Here we show that NRT contain a variety of bacteria and fungi within their bodies in which environment they could be protected from the extremes of the space and released into new cosmic environments. Diatoms were also shown to contain viable alga and Escherichia coli and so could also act as panspermic vehicles for the transfer of these and perhaps other microbes through space. Although not studied here, NRT, and possibly diatoms, also carry protozoa and viruses within their bodies and could act as vehicles for the panspermic transfer of an even wider range of microbes than shown here. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extromophiles" title="extromophiles">extromophiles</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=panspermia" title=" panspermia"> panspermia</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20in%20space" title=" survival in space"> survival in space</a> </p> <a href="https://publications.waset.org/abstracts/3350/nematodes-rotifers-tardigrades-and-diatoms-as-vehicles-for-the-panspermic-transfer-of-microbes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3350.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">559</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">391</span> Mass Production of Endemic Diatoms in Polk County, Florida Concomitant with Biofuel Extraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melba%20D.%20Horton">Melba D.

Diatoms are unique forms of algae characterized by silicified cell walls which have gained prominence in various technological applications. Polk County is home to a multitude of ponds and lakes but has not been explored for the presence of diatoms. Considering the condition of the waters brought about by predominant phosphate mining activities in the area, this research was conducted to determine if endemic diatoms are present and explore their potential for low-cost mass production. Using custom-built photobioreactors, water samples from various lakes provided by the Polk County Parks and Recreation and from nearby ponds were used as the source of diatoms together with other algae obtained during collection. Results of the initial culture cycles were successful, but later an overgrowth of other algae crashed the diatom population. Experiments were conducted in the laboratory to tease out some factors possibly contributing to the die-off. Generally, the total biomass declines after two culture cycles and the causative factors need further investigation. The lipid yield is minimum; however, the high frustule production after die-off adds value to the overall benefit of the harvest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=algae" title=" algae"> algae</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuel" title=" biofuel"> biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid" title=" lipid"> lipid</a>, <a href="https://publications.waset.org/abstracts/search?q=photobioreactor" title=" photobioreactor"> photobioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=frustule" title=" frustule"> frustule</a> </p> <a href="https://publications.waset.org/abstracts/141873/mass-production-of-endemic-diatoms-in-polk-county-florida-concomitant-with-biofuel-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">390</span> Phylogenetic Analysis and a Review of the History of the Accidental Phytoplankter, Phaeodactylum tricornutum Bohlin (Bacillariophyta)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20S.%20M.%20Sabir">Jamal S.

We have incorporated several new raphid pennates into a three-gene phylogenetic dataset (SSU, rbcL, psbC), and recover Gomphonemopsis sp. as sister to P. tricornutum with 100% BS support. This is the first time a close relative has been identified for P. tricornutum with robust statistical support. We test and reject a succession of hypotheses for other relatives. Our molecular data are statistically significantly incongruent with placement of either or both species among the Cymbellales, an order of diatoms with which both have been associated. We believe that further resolution of the phylogenetic position of P. tricornutum will rely more on increased taxon sampling than increased genetic sampling. Gomphonemopsis is a benthic diatom, and its phylogenetic relationship with P. tricornutum is congruent with the hypothesis that P. tricornutum is a benthic diatom with specific adaptations that lead to active recruitment into the plankton. We hypothesize that other benthic diatoms are likely to have similar adaptations and are not merely passively recruited into the plankton. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benthic" title="benthic">benthic</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms%3B%20ecology" title=" diatoms; ecology"> diatoms; ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=Phaeodactylum%20tricornutum" title=" Phaeodactylum tricornutum"> Phaeodactylum tricornutum</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogeny" title=" phylogeny"> phylogeny</a>, <a href="https://publications.waset.org/abstracts/search?q=tychoplankton" title=" tychoplankton "> tychoplankton </a> </p> <a href="https://publications.waset.org/abstracts/91315/phylogenetic-analysis-and-a-review-of-the-history-of-the-accidental-phytoplankter-phaeodactylum-tricornutum-bohlin-bacillariophyta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">389</span> Timing and Impacts of Megafloods in the North Pacific as Recorded by Freshwater Diatoms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Lopes">Cristina Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20C.%20Mix"> Alan C. Mix</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The timing and extension of large discharges from glacial lakes, known as megafloods, into the oceans have been of key importance. This type of events can influence the oceanic/land interactions and even be related with climate changes. While the impact of such floods has been fairly studied in the North Atlantic, the impact of analog floods in the North Pacific remains debatable and relatively unknown. Here we will show records of the Missoula floods that have carved the Northwest landscape and have entered the North Pacific through the Columbia River. These records are given by the presence of high (more than 40%) percentages of freshwater diatoms in marine sediments. A regression equation using these percentages allows to estimate by how much the salinities decreased. The timing and impact of North Pacific megafloods recorded in three marine cores of Oregon and California for the past 25000 years (B.P.) will be presented. These records show that the volume of freshwater that entered the North Pacific reached as far as 600 Km south of the Columbia River Mouth, decreasing the salinities by as much as 4 units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=megafloods" title=" megafloods"> megafloods</a>, <a href="https://publications.waset.org/abstracts/search?q=Missoula" title=" Missoula"> Missoula</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Pacific" title=" North Pacific"> North Pacific</a> </p> <a href="https://publications.waset.org/abstracts/103119/timing-and-impacts-of-megafloods-in-the-north-pacific-as-recorded-by-freshwater-diatoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">388</span> Critical Evaluation of Long Chain Hydrocarbons with Biofuel Potential from Marine Diatoms Isolated from the West Coast of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indira%20K.">Indira K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Valsamma%20Joseph"> Valsamma Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20S.%20Bright"> I. S. Bright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction :Biofuels could replace fossil fuels and reduce our carbon footprint on the planet by technological advancements needed for sustainable and economic fuel production. Micro algae have proven to be a promising source to meet the current energy demand because of high lipid content and production of high biomass rapidly. Marine diatoms, which are key contributors in the biofuel sector and also play a significant role in primary productivity and ecology with high biodiversity and genetic and chemical diversity, are less well understood than other microalgae for producing hydrocarbons. Method :The marine diatom samples selected for hydrocarbon analysis were a total of eleven, out of which 9 samples were from the culture collection of NCAAH, and the remaining two of them were isolated by serial dilution method to get a pure culture from a mixed culture of microalgae obtained from the various cruise stations (350&357) FORV Sagar Sampada along the west coast of India. These diatoms were mass cultured in F/2 media, and the biomass harvested. The crude extract was obtained from the biomass by homogenising with n-hexane, and the hydrocarbons was further obtained by passing the crude extract through 500mg Bonna Agela SPE column and the quantitative analysis was done by GCHRMS analysis using HP-5 column and Helium gas was used as a carrier gas(1ml/min). The injector port temperature was 2400C, the detector temperature was 2500C, and the oven was initially kept at 600C for 1 minute and increased to 2200C at the rate of 60C per minute, and the analysis of a mixture of long chain hydrocarbons was done .Results:In the qualitative analysis done, the most potent hydrocarbon was found to be Psammodictyon Panduriforme (NCAAH-9) with a hydrocarbon mass of 37.27mg/g of the biomass and 2.1% of the total biomass 0f 1.395g and the other potent producer is Biddulphia(NCAAH 6) with hydrocarbon mass of 25.4mg/g of biomass and percentage of hydrocarbon is 1.03%. In the quantitative analysis by GCHRMS, the long chain hydrocarbons found in most of the marine diatoms were undecane, hexadecane, octadecane 3ethyl 5,2 ethyl butyl, Eicosane7hexyl, hexacosane, heptacosane, heneicosane, octadecane 3 methyl, triacontane. The exact mass of the long chain hydrocarbons in all the marine diatom samples was found to be Nonadecane 12C191H40, Tritriacontane,13-decyl-13-heptyl 12C501H102, Octadecane,3ethyl-5-(2-ethylbutyl 12C261H54, tetratetracontane 12C441H89, Eicosane, 7-hexyl 12C261H54. Conclusion:All the marine diatoms screened produced long chain hydrocarbons which can be used as diesel fuel with good cetane value example, hexadecane, undecane. All the long chain hydrocarbons can further undergo catalytic cracking to produce short chain alkanes which can give good octane values and can be used as gasoline. Optimisation of hydrocarbon production with the most potent marine diatom yielded long chain hydrocarbons of good fuel quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofuel" title="biofuel">biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbons" title=" hydrocarbons"> hydrocarbons</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20diatoms" title=" marine diatoms"> marine diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a> </p> <a href="https://publications.waset.org/abstracts/164701/critical-evaluation-of-long-chain-hydrocarbons-with-biofuel-potential-from-marine-diatoms-isolated-from-the-west-coast-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164701.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">387</span> Nuances of Urban Ecology in the Present Global Scenario: Scope, Issues, Challenges and Implications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meenakshi%20Pappu">Meenakshi Pappu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The term, 'urban ecology' has often been misconstrued by the educational practitioners as well as the researchers as a study under a single discipline i.e., the environmental sciences. One who has done research extensively in this study would always argue that urban ecology is not a study under a single discipline, but it is a study across disciplines such as social sciences and other sciences like architecture, engineering, planning, ecology, geography, biology, economics, sociology, anthropology, psychology and health sciences. The aim of this paper is to discuss at length the scope of Urban Ecology as an interdisciplinary study. The paper highlights the nuances of urban ecology as a study across disciplines and the challenges and the implications it holds for future research by conducting a qualitative survey in the particular areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20practitioners" title="educational practitioners">educational practitioners</a>, <a href="https://publications.waset.org/abstracts/search?q=interdisciplinary" title=" interdisciplinary"> interdisciplinary</a>, <a href="https://publications.waset.org/abstracts/search?q=researchers" title=" researchers"> researchers</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20ecology" title=" urban ecology"> urban ecology</a> </p> <a href="https://publications.waset.org/abstracts/60758/nuances-of-urban-ecology-in-the-present-global-scenario-scope-issues-challenges-and-implications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60758.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">386</span> Trophic Ecology of Sarotherodon Melanotheron Heudelotii and Tilapia Guineensis from the Banc D'Arguin National Park, Mauritania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N%C3%A9n%C3%A9%20Gall%C3%A9%20Kide">Néné Gallé Kide</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamadou%20Dia"> Mamadou Dia</a>, <a href="https://publications.waset.org/abstracts/search?q=Lemhaba%20Ould%20Yarba"> Lemhaba Ould Yarba</a>, <a href="https://publications.waset.org/abstracts/search?q=Youssouf%20Kone"> Youssouf Kone</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatimetou%20Mint%20Khalil"> Fatimetou Mint Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajar%20Bouksir"> Hajar Bouksir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghislane%20Salhi"> Ghislane Salhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn%C3%A8s%20Saoud"> Younès Saoud </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The diet of Sarotherodon melanotheron and Tilapia guineensis were investigated in the National Park of Banc d'Arguin (PNBA) from September 2012 to October 2013. A total of 499 individuals ranging in size between 219 and 400 mm total length of S. melanotheron (253 males and 246 females), and 280 individuals of T.guineensis (229 males and 51 females) ranged between 180 and 424mm total length. We used for studying the feeding habits of both two species the frequency of occurrence method. The coefficient of emptiness was 40.88% for S. melanotheron and 38.57% for T. guineensis. Both two species were herbivorous and very close feedings. Their diet consists of Seagrass, green, red, blue, and brown algae, diatoms, gastropods, bivalves, Crustaceans, and mud. The Seagrass and green algae were prey preference of these two species. The diet feeding showed that the composition varies slightly depending on the season and size of individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cichlidae" title="Cichlidae">Cichlidae</a>, <a href="https://publications.waset.org/abstracts/search?q=trophic%20ecology" title=" trophic ecology"> trophic ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=National%20park" title=" National park"> National park</a>, <a href="https://publications.waset.org/abstracts/search?q=Banc%20d%27Arguin" title=" Banc d'Arguin"> Banc d'Arguin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauritania" title=" Mauritania"> Mauritania</a> </p> <a href="https://publications.waset.org/abstracts/16683/trophic-ecology-of-sarotherodon-melanotheron-heudelotii-and-tilapia-guineensis-from-the-banc-darguin-national-park-mauritania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16683.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">795</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">385</span> Response of Subfossile Diatoms, Cladocera, and Chironomidae in Sediments of Small Ponds to Changes in Wastewater Discharges from a Zn–Pb Mine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ewa%20Szarek-Gwiazda">Ewa Szarek-Gwiazda</a>, <a href="https://publications.waset.org/abstracts/search?q=Agata%20Z.%20Wojtal"> Agata Z.

The response of organisms to environmental changes can be well recorded in sediments of the affected water bodies and may be reconstructed based on analyses of organisms' remains. The present study aimed at the response of diatoms (Bacillariophyta), Cladocera, and Chironomidae communities to the impact of Zn-Pb mine water discharge recorded in sediment cores of small subsidence ponds on the Chechło River floodplain (Silesia–Krakow Region, southern Poland). We hypothesize various responses of the above groups to high metal concentrations (Cd, Pb, Zn, and Cu). The investigated ponds were formed either during the peak of the ore exploitation (DOWN) or after mining cessation (UP). Currently, the concentrations of dissolved metals (in µg g⁻¹) in water reached up to 0.53 for Cd, 7.3 for Pb, and up to 47.1 for Zn. All the sediment cores from subsidence ponds were heavily polluted with Cd 6.7–612 μg g⁻¹, Pb 0.1–10.2 mg g⁻¹, and Zn 0.5–23.1 mg g⁻¹. Core sediments varied also in respect to pH 5.8-7.1 and concentrations of organic matter (5.7-39.8%). The impact of high metal concentrations was expressed by the occurrence of metal-tolerant taxa like diatoms – Nitzschia amphibia, Sellaphora nigri, and Surirella brebisonii var. kuetzingii; Cladocera – Chydorus sphaericus (dominated in cores from all ponds), and Chironomidae – Chironomus and Cricotopus especially in the DOWN ponds. Statistical analysis exhibited a negative impact of metals on some taxa of diatoms and Cladocera but only on Polypedilum sp. from Chironomidae. The abundance of such diatoms like Gomphonema utae, Staurosirella pinnata, Eunotia bilunaris, and Cladocera like Alona, Chydorus, Graptoleberis, and Pleuroxus decreased with increasing Pb concentration. However, the occurrence or dominance of more sensitive species of diatoms and Cladocera indicates their adaptation to higher metal loads, which was facilitated by neutral pH and slightly alkaline waters. Diatom assemblages were generally resistant to Zn, Pb, Cu, and Cd pollution, as indicated by their large similarity to populations from non-contaminated waters. Comparison with reference objects clearly indicates the dominance of Achnanthidium minutissimum, Staurosira venter, and Fragilaria gracilis in very diverse assemblages of unpolluted waters. The distribution of the Cladocera and Chironomidae taxa depended on the habitat type. The DOWN ponds with stagnant water and overgrown with macrophytes were more suitable for cladocerans (14 taxa, higher diversity) than the UP ponds with river water flowing through their centre and with a small share of macrophytes (8 taxa). The Chironominae, mainly Chironomus and Microspectra, were abundant in cores from the UP ponds with muddy bottoms. Inversely, the density of Orthocladiinae, especially genus Cricotopus, was related to the organic matter content and dominated in cores from the DOWN ponds. The presence of diatoms like Nitzschia amphibia, Sellaphora nigri, and Surirella brebisonii var. kuetzingii, cladocerans: Bosmina longirostris, Chydorus sphaericus, Alona affinis, and A. rectangularis as well as Chironomidae Chironomus sp. (UP ponds) and Psecrotanypus varius (DOWN ponds) indicate the influence of the water trophy on their distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chironomidae" title="Chironomidae">Chironomidae</a>, <a href="https://publications.waset.org/abstracts/search?q=Cladocera" title=" Cladocera"> Cladocera</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn-Pb%20mine" title=" Zn-Pb mine"> Zn-Pb mine</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20cores" title=" sediment cores"> sediment cores</a>, <a href="https://publications.waset.org/abstracts/search?q=subsidence%20ponds" title=" subsidence ponds"> subsidence ponds</a> </p> <a href="https://publications.waset.org/abstracts/176661/response-of-subfossile-diatoms-cladocera-and-chironomidae-in-sediments-of-small-ponds-to-changes-in-wastewater-discharges-from-a-zn-pb-mine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176661.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">384</span> Unfolding Global Biodiversity Patterns of Marine Planktonic Diatom Communities across the World's Oceans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shruti%20Malviya">Shruti Malviya</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Bowler"> Chris Bowler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of microbial eukaryotic diversity is fundamental to understanding ecosystems’ structure, biology, and ecology. Diatoms (Stramenopiles, Bacillariophyceae) are one of the most diverse and ecologically prominent groups of phytoplankton. This study was performed to enhance the understanding of global biodiversity patterns and structure of planktonic diatom communities across the world's oceans. We used the metabarcoding data set generated from the biological samples and associated environmental data collected during the Tara Oceans (2009-2013) global circumnavigation covering all major oceanic provinces. A total of ~18 million diatom V9-18S rDNA tags from 126 sampling stations, constituting 631 size-fractionated plankton communities were generated. Using ~250,000 unique diatom metabarcodes, the global diatom distribution and diversity across size classes, genus and ecological niches was assessed. Notably, our analysis revealed: (i) a new estimate of the total number of planktonic diatom species, (ii) a considerable unknown diversity and exceptionally high diversity in the open ocean, and (iii) complex diversity patterns across oceanic provinces. Also, co-occurrence of several ribotypes in locations separated by great geographic distances (equatorial stations) demonstrated a widespread but not ubiquitous distribution. This work provides a comprehensive perspective on diatom distribution and diversity in the world’s oceans and elaborates interconnections between associated theories and underlying drivers. It shows how meta-barcoding approaches can provide a framework to investigate environmental diversity at a global scale, which is deemed as an essential step in answering various ecological research questions. Consequently, this work also provides a reference point to explore how microbial communities will respond to environmental conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=Tara%20Oceans" title=" Tara Oceans"> Tara Oceans</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=metabarcoding" title=" metabarcoding"> metabarcoding</a> </p> <a href="https://publications.waset.org/abstracts/87703/unfolding-global-biodiversity-patterns-of-marine-planktonic-diatom-communities-across-the-worlds-oceans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87703.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">383</span> Effect of Chain Length on Skeletonema pseudocostatum as Probed by THz Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruqyyah%20Mushtaq">Ruqyyah Mushtaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiacar%20Gamberdella"> Chiacar Gamberdella</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberta%20Miroglio"> Roberta Miroglio</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Novelli"> Fabio Novelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Domenica%20Papro"> Domenica Papro</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Paturzo"> M.

Specifically, we explored whether metal toxicants could affect the growth of these algal chains, potentially serving as an ecotoxicological indicator of heavy metal pollution. We utilized THz spectroscopy in conjunction with standard optical microscopy to observe the formation of these chains and their response to toxicants. Despite the strong absorption of terahertz radiation in water, we demonstrate that changes in water absorption in the terahertz range due to water-diatom interaction can provide insights into diatom chain length. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=THz-TDS%20spectroscopy" title="THz-TDS spectroscopy">THz-TDS spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20ecotoxicology" title=" marine ecotoxicology"> marine ecotoxicology</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20pollution" title=" marine pollution"> marine pollution</a> </p> <a href="https://publications.waset.org/abstracts/188473/effect-of-chain-length-on-skeletonema-pseudocostatum-as-probed-by-thz-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188473.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">31</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">382</span> Effect of Urbanization on Basic Environmental Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sehba%20Saleem">Sehba Saleem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A country with a spread of only 2.4 percent of the total land surface area of the world, India is home to 17.5 percent of the world population. This fact is sufficient enough to delineate as well as simultaneously bringing to fore the paradox which exists between land and human population. It is evident that the relation which exists between both is an unequal one where the latter has the ability to multiply self, but the former remains constant. This unequal relation that exists has very significantly contributed to the depletion in the quality of land. This is because construction of every kind and nature has been forced on the land to assimilate the ever increasing population which has altered the not only the land but the environment which existed on the land. To get behind this alteration, it becomes imperative to delve into concepts like urbanization, ecology and their amalgam viz. urban ecology. The concept of urban ecology does not only involve study of buildings, flora, and fauna which exists in a given land space. It goes further into establishing a relation between construction on land and the consequent harm, which the same is causing to the environmental resources like air, water etc. This paper shall try cerebrating concepts of urbanization, ecology and urban ecology in the light of relation which exists between man and nature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetrical%20growth" title="asymmetrical growth">asymmetrical growth</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanisation" title=" urbanisation"> urbanisation</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20space" title=" urban space"> urban space</a> </p> <a href="https://publications.waset.org/abstracts/49633/effect-of-urbanization-on-basic-environmental-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49633.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">381</span> Analysis and Study of Phytoplankton and the Environmental Characteristics of Tarkwa Bay, Lagos, South-Western, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bukola%20Dawodu">Bukola Dawodu</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Onyema"> Charles Onyema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The phytoplankton and environmental characteristics of Tarkwa Bay, Lagos in South-western Nigeria were investigated from January to June 2012. Environmental characteristics within the Bay were largely determined by floodwater inflow in the wet months (April – June) and increased tidal marine conditions in the dry months (January – March). Similarly, rainfall distribution and possibly tidal seawater inflow were the key factors that govern the variation in phytoplankton distribution, species diversity, chlorophyll a concentration and environmental characteristics of the bay. Values for physico-chemical parameters were indicative of high levels of fluctuations inwards from the East mole towards Tarkwa Bay (e.g. T.S.S > 11mg/L, T.D.S > 33541.0mg/L, D.O. < 5.4). Chlorophyll A values did not show any discernable pattern and correlated negatively with total dissolved solids and total suspended solids (r = -0.27 and -0.04) as both were inconsistent throughout the study period. Four phytoplankton divisions were observed throughout the sampling period with the Bacillariophyta (diatoms) being the dominant group followed by Dinophyta (dinoflagellates), Cyanophyta (the blue-green algae) and Chlorophyta (the green algae). A total of twenty-one species from nine genera were recorded during the period of study. Diatoms formed the most abundant group making fifteen species from five genera. The centric forms dominated over the pennates in the diatom group with Skeletonema sp. Chaetoceros spp. and Coscinodiscus spp. being the dominant centric diatoms while Navicula spp. was the more dominant pennate form. The Dinoflagellates were represented by six species from one genus, the blue-green algae with five species from two genera while the green algae had one species from one genus. Comparatively, total biomass was more in the dry months (Jan. - Mar.) and decreased in the 'wet months' (Apr. – Jun.). Species diversity (S), Shannon Wiener index (Hs), Margalef Index (d) and Equitability Index (j) values were higher during the dry months while reduced value marked the wet months possibly as a result of dilution of rain effects. Outcomes of bio-indices variations were reflections of the degree of occurrence and abundance of species linked to seasons operating in the study site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20waters" title="coastal waters">coastal waters</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoplankton" title=" phytoplankton"> phytoplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20abundance" title=" species abundance"> species abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystems" title=" ecosystems"> ecosystems</a> </p> <a href="https://publications.waset.org/abstracts/75259/analysis-and-study-of-phytoplankton-and-the-environmental-characteristics-of-tarkwa-bay-lagos-south-western-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">380</span> Agroecology Techniques in Palestine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rima%20Younis">Rima Younis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agro-ecology is considered one of the agricultural approaches that is spreading across the world due to the practical solutions it provides that are in harmony with nature. These solutions target many agricultural problems, food production issues, and climate change. Agriculture and fertile soil in particular, play a vital role when it comes to food security and climate change. The organic substances, which mainly consist of carbon, in the soil contribute to the ecological system through 4 elements: Resistance to soil erosion, conserving water in soil, increasing soil fertility, and improving the biodiversity in it. Any small changes to the carbon storage in soil have a tremendous impact on both agricultural productivity and the greenhouse gas cycle, which is what agro-ecology aims to achieve. The importance of agro-ecology lies here, as it helps increase organic matter/carbon in the soil, on an ongoing basis, 15-20 times higher than nature’s rate in producing organic matter. Agro-ecology is set to increase the production of crops free of chemicals, develop organic matter, and establish carbon in soil, thus being a factor in limiting climate change, not just mitigating or adapting. Under the events of the rapid increase in population and the need to feed humans, agro-ecology stands in the first place as it surpasses the productivity of chemical agriculture per unit area, according to international and local experience. The introduction of agro-ecology to Palestine started 15 years ago, with modest beginnings faced with a lot of criticism and opposition, but is currently experiencing rapid growth among farmers and is becoming accepted among specialists. Even though the number of agro-ecologist farmers is still small, it reflects a state of turnover into a more sustainable, less polluting agriculture that works on renewing life and the elements of nature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toward%20to%20solidarity%20economy" title="toward to solidarity economy">toward to solidarity economy</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20sovereignty" title=" food sovereignty"> food sovereignty</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20introduction%20of%20agro-ecology%20to%20Palestine" title=" the introduction of agro-ecology to Palestine"> the introduction of agro-ecology to Palestine</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20importance%20of%20agro-ecology" title=" the importance of agro-ecology"> the importance of agro-ecology</a> </p> <a href="https://publications.waset.org/abstracts/191529/agroecology-techniques-in-palestine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191529.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">25</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">379</span> Sleep Ecology, Sleep Regulation and Behavior Problems in Maltreated Preschoolers: A Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabrina%20Servot">Sabrina Servot</a>, <a href="https://publications.waset.org/abstracts/search?q=Annick%20St-Amand"> Annick St-Amand</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Rousseau"> Michel Rousseau</a>, <a href="https://publications.waset.org/abstracts/search?q=Valerie%20Simard"> Valerie Simard</a>, <a href="https://publications.waset.org/abstracts/search?q=Evelyne%20Touchette"> Evelyne Touchette</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Child maltreatment has a profound impact on children’s development. In its victims, internalizing and externalizing problems are highly prevalent, and sleep problems are common. Furthermore, the environment they live in is often disorganized, lacking routine and consistency. In non-maltreated children, several studies documented the important role of sleep regulation and sleep ecology. A poor sleep ecology (e.g., lack of sleep hygiene and bedtime routine, inappropriate sleeping location) may lead to sleep regulation problems (e.g., short sleep duration, nocturnal awakenings), and sleep regulation problems may increase the risk of behavior problems. Therefore, this scoping review aims to map evidence about sleep ecology and sleep regulation and the associations between sleep ecology, sleep regulation, and behavior problems in maltreated preschoolers. Literature from 1993 was searched in PsycInfo, Pubmed, Medline, Eric, and Proquest Dissertations and Theses. Articles and thesis were comprehensively reviewed based upon inclusion/exclusion criteria: 1) it concerns maltreated children aged 1-5 years, and 2) it addresses at least one of the following: sleep ecology, sleep regulation, and/or their associations with behavior problems in maltreated preschoolers. From the 650 studies screened, nine of them were included. Data were charted according to study characteristics, nature of variable documented, measures, analyses performed, and results of each study, then synthesized in a narrative summary. The main results show all included articles were quantitative. Foster children samples were used in four studies, children experienced different types of maltreatment in six studies, while one was specifically about sexually abused children. Regarding sleep ecology, only one study describing maltreated preschoolers’ sleep ecology was found, while seven studies documented sleep regulation. Among these seven studies, 17 different sleep variables (e.g., parasomnia, dyssomnia, total 24-h sleep duration) were used, each study documenting from one to nine of them. Actigraphic measures were employed in three studies, the others used parent-reported questionnaires or sleep diaries. Maltreated children’s sleep was described and/or compared to non-maltreated children’s sleep, or an intervention group, showing mild differences. As for associations between sleep regulation and behavior problems, five studies investigated it and performed correlational or linear regression analyses between sleep and behavior problems, revealing some significant associations. No study was found about associations between sleep ecology and sleep regulation, between sleep ecology and behavior problems, or between these three variables. In conclusion, literature about sleep ecology, sleep regulation, and their associations with behavior problems are far more scarce in maltreated preschoolers than in non-maltreated ones. At present, there is especially a paucity of research about sleep ecology and the association between sleep ecology and sleep regulation in maltreated preschoolers, while studies on non-maltreated children showed sleep ecology plays a major role in sleep regulation. In addition, as sleep regulation is measured in many different ways among the studies, it is difficult to compare their findings. Finally, it seems necessary that research fill these gaps, as recommendations could be made to clinicians working with maltreated preschoolers regarding the use of sleep ecology and sleep regulation as intervention tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maltreated%20preschoolers" title="maltreated preschoolers">maltreated preschoolers</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20ecology" title=" sleep ecology"> sleep ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20regulation" title=" sleep regulation"> sleep regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20problems" title=" behavior problems"> behavior problems</a> </p> <a href="https://publications.waset.org/abstracts/131448/sleep-ecology-sleep-regulation-and-behavior-problems-in-maltreated-preschoolers-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131448.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">378</span> Industrial Ecology Perspectives of Food Supply Chains: A Framework of Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Batista">Luciano Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvia%20Saes"> Sylvia Saes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Fouto"> Nuno Fouto</a>, <a href="https://publications.waset.org/abstracts/search?q=Liam%20Fassam"> Liam Fassam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces the theoretical and methodological basis of an analytical framework conceived with the purpose of bringing industrial ecology perspectives into the core of the underlying disciplines supporting analyses in studies concerned with environmental sustainability aspects beyond the product cycle in a supply chain. Given the pressing challenges faced by the food sector, the framework focuses upon waste minimization through industrial linkages in food supply chains. The combination of industrial ecology practice with basic LCA elements, the waste hierarchy model, and the spatial scale of industrial symbiosis allows the standardization of qualitative analyses and associated outcomes. Such standardization enables comparative analysis not only between different stages of a supply chain, but also between different supply chains. The analytical approach proposed contributes more coherently to the wider circular economy aspiration of optimizing the flow of goods to get the most out of raw materials and cuts wastes to a minimum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=by-product%20synergy" title="by-product synergy">by-product synergy</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20supply%20chain" title=" food supply chain"> food supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20ecology" title=" industrial ecology"> industrial ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20symbiosis" title=" industrial symbiosis"> industrial symbiosis</a> </p> <a href="https://publications.waset.org/abstracts/20036/industrial-ecology-perspectives-of-food-supply-chains-a-framework-of-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20036.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">377</span> Effects of Jigsaw Strategy on Senior Secondary School Students’ Achievement in Ecology in Maitagari, Jigawa State, Nigeriaind Out the Effect of Jigsaw Strategy on Students’ Achievement in Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozoji%20Bernadette">Ozoji Bernadette</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%E2%80%99Ad-Abdullahi%20Abdulhafiz"> Sa’Ad-Abdullahi Abdulhafiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Izundu%20Chike%20Leo"> Izundu Chike Leo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigated the effect of Jigsaw strategy on senior secondary school students’ achievement in Maitagari, Jigawa State, Nigeria. The pre-test, post-test quasi experimental design was employed in the study. The sample for the study comprised 120 students from two public schools from the study area. An instrument namely, Ecological Achievement Test (EAT) was used to collect data from students. The data were analyzed using SPSS version 26.0. The EAT was validated by two experts, one, in Science Education unit and the other in Research, Measurement and Evaluation unit, both in the Faculty of Education, University of Jos, Nigeria. The reliability coefficient of the EAT was established as 0.85 using Kuder Richardson Formular 20. Mean and standard deviation were used to answer two research questions while Analysis of Covariance was used to test two hypotheses that guided the study. Results showed that students taught using jigsaw strategy achieved significantly better than their counterparts taught using the conventional method in ecology. Furthermore, it was revealed that gender had no significant influence on achievement of students exposed to jigsaw strategy. It was concluded that jigsaw strategy was effective in improving students’ achievement in ecology. The study recommended that teachers should incorporate jigsaw strategy into science classrooms for improved achievement outcome and gender equality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=achievement" title="achievement">achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=ecology" title=" ecology"> ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=jigsaw%20strategy" title=" jigsaw strategy"> jigsaw strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=lecture%20strategy" title=" lecture strategy"> lecture strategy</a> </p> <a href="https://publications.waset.org/abstracts/156037/effects-of-jigsaw-strategy-on-senior-secondary-school-students-achievement-in-ecology-in-maitagari-jigawa-state-nigeriaind-out-the-effect-of-jigsaw-strategy-on-students-achievement-in-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156037.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">376</span> The Renewal of Chinese Urban Village on Cultural Ecology: Hubei Village as an Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaojun%20Zheng">Shaojun Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Xu"> Lei Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yunzi%20Wang"> Yunzi Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of the research is to use the cultural ecology to analyze the renewal of Shenzhen urban village in the process of China's urbanization and to evaluate and guide the renewal, which will combine the society value and economic efficiency and activate urban villages. The urban village has a long history. There are also many old buildings, various residents, and a strong connection with the surrounding environment. Cultural ecology, which uses the knowledge of ecology to study culture, provides us a cultural perspective in the renewal. We take Hubei village in Shenzhen as our example. By using cultural ecology, we find a new way dealing with the relationship between culture and other factors. It helps us to give the buildings and space the culture meanings from different scales. It enables us to find a unique development pattern of urban village. After analyzing several famous cultural blocks cases, we find it is possible to connect the unique culture of urban village with the renovation of its buildings, community, and commerce. We propose the following strategies with specific target: 1. Building renovation: We repair and rebuild the origin buildings as little as possible, and retain the original urban space tissue as much as possible to keep the original sense of place and the cultural atmosphere. 2. Community upgrade: We reshape the village stream, fix the original function, add event which will activate people to complete the existing cultural circle 3. District commerce: We implant food and drink district, boutique commercial, and creative industries, to make full use of the historical atmosphere of the site to enhance the culture feelings For the renewal of a seemingly chaotic mixed urban village, it is important to break out from the conventional practices of building shopping malls or residential towers. Without creating those building landmarks, cultural ecology activates the urban village by exploiting its unique culture, which makes the old and new combine and becomes a new stream of energy, forming the new cultural, commercial and stylish landmark of the city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20ecology" title="cultural ecology">cultural ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20village" title=" urban village"> urban village</a>, <a href="https://publications.waset.org/abstracts/search?q=renewal" title=" renewal"> renewal</a>, <a href="https://publications.waset.org/abstracts/search?q=combination" title=" combination"> combination</a> </p> <a href="https://publications.waset.org/abstracts/47016/the-renewal-of-chinese-urban-village-on-cultural-ecology-hubei-village-as-an-example" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47016.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">375</span> Integrating Molecular Approaches to Understand Diatom Assemblages in Marine Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shruti%20Malviya">Shruti Malviya</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Bowler"> Chris Bowler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental processes acting at multiple spatial scales control marine diatom community structure. However, the contribution of local factors (e.g., temperature, salinity, etc.) in these highly complex systems is poorly understood. We, therefore, investigated the diatom community organization as a function of environmental predictors and determined the relative contribution of various environmental factors on the structure of marine diatoms assemblages in the world’s ocean. The dataset for this study was derived from the Tara Oceans expedition, constituting 46 sampling stations from diverse oceanic provinces. The V9 hypervariable region of 18s rDNA was organized into assemblages based on their distributional co-occurrence. Using Ward’s hierarchical clustering, nine clusters were defined. The number of ribotypes and reads varied within each cluster-three clusters (II, VIII and IX) contained only a few reads whereas two of them (I and IV) were highly abundant. Of the nine clusters, seven can be divided into two categories defined by a positive correlation with phosphate and nitrate and a negative correlation with longitude and, the other by a negative correlation with salinity, temperature, latitude and positive correlation with Lyapunov exponent. All the clusters were found to be remarkably dominant in South Pacific Ocean and can be placed into three classes, namely Southern Ocean-South Pacific Ocean clusters (I, II, V, VIII, IX), South Pacific Ocean clusters (IV and VII), and cosmopolitan clusters (III and VI). Our findings showed that co-occurring ribotypes can be significantly associated into recognizable clusters which exhibit a distinct response to environmental variables. This study, thus, demonstrated distinct behavior of each recognized assemblage displaying a taxonomic and environmental signature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assemblage" title="assemblage">assemblage</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20clustering" title=" hierarchical clustering"> hierarchical clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=Tara%20Oceans" title=" Tara Oceans"> Tara Oceans</a> </p> <a href="https://publications.waset.org/abstracts/87705/integrating-molecular-approaches-to-understand-diatom-assemblages-in-marine-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">374</span> Exploring the Intrinsic Ecology and Suitable Density of Historic Districts Through a Comparative Analysis of Ancient and Modern Ecological Smart Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hu%20Changjuan">Hu Changjuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gong%20Cong"> Gong Cong</a>, <a href="https://publications.waset.org/abstracts/search?q=Long%20Hao"> Long Hao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although urban ecological policies and the public's aspiration for livable environments have expedited the pace of ecological revitalization, historic districts that have evolved through natural ecological processes often become obsolete and less habitable amid rapid urbanization. This raises a critical question about historic districts inherently incapable of being ecological and livable. The thriving concept of ‘intrinsic ecology,’ characterized by its ability to transform city-district systems into healthy ecosystems with diverse environments, stable functions, and rapid restoration capabilities, holds potential for guiding the integration of ancient and modern ecological wisdom while supporting the dynamic involvement of cultures. This study explores the intrinsic ecology of historic districts from three aspects: 1) Population Density: By comparing the population density before urban population expansion to the present day, determine the reasonable population density for historic districts. 2) Building Density: Using the ‘Space-mate’ tool for comparative analysis, form a spatial matrix to explore the intrinsic ecology of building density in Chinese historic districts. 3) Green Capacity Ratio: By using ecological districts as control samples, conduct dual comparative analyses (related comparison and upgraded comparison) to determine the intrinsic ecological advantages of the two-dimensional and three-dimensional green volume in historic districts. The study inform a density optimization strategy that supports cultural, social, natural, and economic ecology, contributing to the creation of eco-historic districts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco-historic%20districts" title="eco-historic districts">eco-historic districts</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20ecology" title=" intrinsic ecology"> intrinsic ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=suitable%20density" title=" suitable density"> suitable density</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20capacity%20ratio." title=" green capacity ratio."> green capacity ratio.</a> </p> <a href="https://publications.waset.org/abstracts/189342/exploring-the-intrinsic-ecology-and-suitable-density-of-historic-districts-through-a-comparative-analysis-of-ancient-and-modern-ecological-smart-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">23</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">373</span> Ecological and Economical Indicators of Successful Community Based Forest Management: A Case of Lowland Community Forestry in Nepal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bikram%20Jung%20Kunwar">Bikram Jung Kunwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Pralhad%20Kunwor"> Pralhad Kunwor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Community-Based Forest Management (CBFM) approach is often glorified as the best forest management alternatives in the developing countries. However, how the approach has been understood by the local user households, who implement it is remained unanswered for many planners, policy makers, and sometimes researcher as well. The study attempts to assess the understanding of ecology and economics of CBFM in Nepal, where community forest program has been implemented since the 1970s. In order to understand the impacts of the program, eight criteria and sixteen indicators for ecological conservation and similarly same number of criteria and indicators for socio-economic impacts of the program were designed and compared between before and after the program implementation. The community forestry program has positive effects in forest ecology conservation and at the same time rural livelihood improvement of local people. The study revealed that collective understanding of forest ecology and economics leads the CBFM approach towards the sustainability of the program in a win-win situation. The recommendations of the study are expected to be useful to natural resource managers, planners, and policy makers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20management" title=" forest management"> forest management</a>, <a href="https://publications.waset.org/abstracts/search?q=ecology" title=" ecology"> ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=economics" title=" economics"> economics</a>, <a href="https://publications.waset.org/abstracts/search?q=Nepal" title=" Nepal"> Nepal</a> </p> <a href="https://publications.waset.org/abstracts/26600/ecological-and-economical-indicators-of-successful-community-based-forest-management-a-case-of-lowland-community-forestry-in-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26600.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">372</span> Environmental Resilience in Sustainability Outcomes of Spatial-Economic Model Structure on the Topology of Construction Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moustafa%20Osman%20Mohammed">Moustafa Osman Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The resilient and sustainable of construction ecology is essential to world’s socio-economic development. Environmental resilience is crucial in relating construction ecology to topology of spatial-economic model. Sustainability of spatial-economic model gives attention to green business to comply with Earth’s System for naturally exchange patterns of ecosystems. The systems ecology has consistent and periodic cycles to preserve energy and materials flow in Earth’s System. When model structure is influencing communication of internal and external features in system networks, it postulated the valence of the first-level spatial outcomes (i.e., project compatibility success).

The model topology has state-of-the-art in value-orientation impact and correspond complexity of sustainability issues (e.g., build a consistent database necessary to approach spatial structure; construct the spatial-economic model; develop a set of sustainability indicators associated with model; allow quantification of social, economic and environmental impact; use the value-orientation as a set of important sustainability policy measures), and demonstrate environmental resilience. The model is managing and developing schemes from perspective of multiple sources pollutants through the input–output criteria. These criteria are evaluated the external insertions effects to conduct Monte Carlo simulations and analysis for using matrices in a unique spatial structure. The balance “equilibrium patterns” such as collective biosphere features, has a composite index of the distributed feedback flows. These feedback flows have a dynamic structure with physical and chemical properties for gradual prolong of incremental patterns. While these structures argue from system ecology, static loads are not decisive from an artistic/architectural perspective. The popularity of system resilience, in the systems structure related to ecology has not been achieved without the generation of confusion and vagueness. However, this topic is relevant to forecast future scenarios where industrial regions will need to keep on dealing with the impact of relative environmental deviations. The model attempts to unify analytic and analogical structure of urban environments using database software to integrate sustainability outcomes where the process based on systems topology of construction ecology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=system%20ecology" title="system ecology">system ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20ecology" title=" construction ecology"> construction ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20ecology" title=" industrial ecology"> industrial ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial-economic%20model" title=" spatial-economic model"> spatial-economic model</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20topology" title=" systems topology"> systems topology</a> </p> <a href="https://publications.waset.org/abstracts/192670/environmental-resilience-in-sustainability-outcomes-of-spatial-economic-model-structure-on-the-topology-of-construction-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192670.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">371</span> A Laboratory–Designed Activity in Ecology to Demonstrate the Allelopathic Property of the Philippine Chromolaena odorata L.

Ethanol extracts of C. odorata leaves were tested on seed germination and seedling growth of L. esculentum in 7-day and 14-day observation periods. Analysis of variance and Tukey’s HSD post hoc test was utilized to determine differences among treatments while Pre–test – Post–test experimental design was utilized in the determination of the effectiveness of the designed laboratory activity. Results showed that the 0.5% concentration level of ethanol leaf extracts significantly inhibited germination and seedling growth of L. esculentum in both observation periods. These results were used as the basis in the development of instructional material in ecology. The laboratory activity underwent face validation by five (5) experts in various fields of specialization, namely, Biological Sciences, Chemistry and Science Education. The readability of the designed laboratory activity was determined using a Cloze Test. Pilot testing was conducted and showed that the laboratory activity developed is found to be a very effective tool in supplementing learning about allelopathy in ecology class. Thus, it is recommended for use among ecology classes but modification will be made in a small – scale basis to minimize time consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allelopathy" title="allelopathy">allelopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=chromolaena%20odorata%20l.%20%28hagonoy%29" title=" chromolaena odorata l.

Naturally, exchange patterns of industrial ecology have consistent and periodic cycles to preserve energy flows and materials in Earth’s System. When engineering topology is affecting internal and external processes in system networks, it postulated the valence of the first-level spatial outcome (i.e., project compatibility success). These instrumentalities are dependent on relating the second-level outcome (i.e., participant security satisfaction). Construction ecology approach feedback energy from resources flows between biotic and abiotic in the entire Earth’s ecosystems. These spatial outcomes are providing an innovation, as entails a wide range of interactions to state, regulate and feedback “topology” to flow as “interdisciplinary equilibrium” of ecosystems. The interrelation dynamics of ecosystems are performing a process in a certain location within an appropriate time for characterizing their unique structure in “equilibrium patterns”, such as biosphere and collecting a composite structure of many distributed feedback flows. These interdisciplinary systems regulate their dynamics within complex structures. These dynamic mechanisms of the ecosystem regulate physical and chemical properties to enable a gradual and prolonged incremental pattern to develop a stable structure. The engineering topology of construction ecology for integration sustainability outcomes offers an interesting tool for ecologists and engineers in the simulation paradigm as an initial form of development structure within compatible computer software. This approach argues from ecology, resource savings, static load design, financial other pragmatic reasons, while an artistic/architectural perspective, these are not decisive.

Algae produce oxygen during photosynthesis, which is taken up by heterotrophic bacteria for mineralizing organic carbon to carbon dioxide. This phenomenon reduces the net mechanical aeration requirement of aerobic biological wastewater treatment processes. Consequently, the treatment cost is also reduced. Microalgae also participate in the treatment process by taking up nutrient (N, P) from wastewater. Algal biomass, if harvested, can generate value-added by-products. The aim of the present study was to compare the performance of two systems - System A (mixed microalgae and bacteria) and System B (diatoms and bacteria) in treating kitchen wastewater (KWW). The test reactors were operated at five different solid retention times (SRTs) -2, 4, 6, 8, and 10-days in draw-and-fill mode. The KWW was collected daily from the dining hall-kitchen area of the Indian Institute of Technology Hyderabad. The influent and effluent samples were analyzed for total organic carbon (TOC), total nitrogen (TN) using TOC-L analyzer. A colorimetric method was used to analyze anionic surfactant. Phosphorus (P) and chlorophyll were measured by following standard methods. The TOC, TN, and P of KWW were in the range of 113.5 to 740 mg/L, 2 to 22.8 mg/L, and 1 to 4.5 mg/L, respectively. Both the systems gave similar results with 85% of TOC removal and 60% of TN removal at 10-d SRT. However, the anionic surfactant removal in System A was 99% and 60% in System B. The chlorophyll concentration increased with an increase in SRT in both the systems. At 2-d SRT, no chlorophyll was observed in System B, whereas 0.5 mg/L was observed in System A. At 10-d SRT, the chlorophyll concentration in System A was 7.5 mg/L, whereas it was 4.5 mg/L in System B. Although both the systems showed similar performance in treatment, the increase in chlorophyll concentration suggests that System A demonstrated a better algal-bacterial symbiotic relationship in treating KWW than System B. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=microalgae" title=" microalgae"> microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=retention%20time" title=" retention time"> retention time</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a> </p> <a href="https://publications.waset.org/abstracts/117873/effect-of-retention-time-on-kitchen-wastewater-treatment-using-mixed-algal-bacterial-consortia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">368</span> Harmful Algal Blooming Micro-Algae in Kenya’s Coastal Waters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Awuor%20Oduor">Nancy Awuor Oduor</a>, <a href="https://publications.waset.org/abstracts/search?q=Nils%20Moosdorf"> Nils Moosdorf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Harmful Algal Blooms (HABs) are a threat to coastal water quality, marine biodiversity, and human health. The attention on HABs and associated phycotoxins is still very low in tropical coastal developing countries despite the high dependence of local communities on coastal and marine resources for food and livelihoods and the growing evidence of the global increase in HABs frequency, toxicity, and geographical expansion. Lack of HABs monitoring thus creates a high risk of exposure due to uncertainty. This study assessed the spatial and temporal variability and effects of potential HAB-forming species in Kenya’s coastal waters. The preliminary results from 463 sampled collected over a series of 10 coastal surveys conducted over 267 Km of Kenya’s coastline between August 2021 and July 2022 revealed the presence of 87 potential algal blooming species belonging to 47 genera dominated by species capable of producing toxins, causing physical harm and high biomass at 41, 31 and 21 % respectively. The taxonomic composition was also dominated by dinoflagellates at 47%, followed by diatoms, cyanobacteria, and silicoflagellates at 39, 12, and 2%, respectively. About 92 % of the toxin-producing species were established in the creek waters. However, there were no significant variations established in species richness between the dry and wet seasons. Paralytic Shellfish Poisoning (PSP) toxin-producing dinoflagellates Alexandrium spp., Aphanizomenon spp., Gonyaulax spp., Gymnodinium spp., and Brachydinium capitatum, and Amnesic Shellfish Poisoning (ASP) Toxin producing diatoms Amphora spp., Nitzschia spp. and Pseudo-nitzschia spp. Frequented the area in low cell densities ranging between 5 and 1500 cells/L. However, no domoic acid (DA) and saxitoxins (SXTs) were detected during the July surveys. This does not mean that the toxins are absent in the area, and longer studies are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=harmful%20algal%20blooms" title="harmful algal blooms">harmful algal blooms</a>, <a href="https://publications.waset.org/abstracts/search?q=phycotoxins" title=" phycotoxins"> phycotoxins</a>, <a href="https://publications.waset.org/abstracts/search?q=saxitoxin" title=" saxitoxin"> saxitoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=domoic%20acid" title=" domoic acid"> domoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenya" title=" Kenya"> Kenya</a> </p> <a href="https://publications.waset.org/abstracts/181207/harmful-algal-blooming-micro-algae-in-kenyas-coastal-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">367</span> Semi-Natural Vertical Gardens and Urban Ecology, the Sample of Bartın City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yeliz%20Sar%C4%B1%20Nayim">Yeliz Sarı Nayim</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20N.%20Nayim"> B.

This research covers the investigation of the semi-natural plant walls of Bartın city which is located on the western Black Sea coast of Turkey. Landscape analysis and evaluation as a result of land and office work have resulted in vertical garden ecosystems that have been processed in the urban habitat map, mostly in natural stone walls, wooden garden fences, garden entrance doors, historical buildings and building walls. Structural surfaces on old building facades, especially with abandoned or still in use with natural stone walls, have been found to have many natural vertical gardens over time. Parietaria judaica, Cymbalaria longipes and Hedera helix species were dominant, and other types of content were recorded, providing information on the current biotope potential, human activities and effects on them. It has been emphasized that the described vertical gardens together with the species they contain should be protected in terms of Bartin urban ecology and biodiversity. It has been stated that sustainable urban planning, design and management should be considered as a compensation for open and green area losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semi-natural%20vertical%20gardens" title="semi-natural vertical gardens">semi-natural vertical gardens</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20ecology" title=" urban ecology"> urban ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20planning%20and%20design" title=" sustainable urban planning and design"> sustainable urban planning and design</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%C4%B1n" title=" Bartın"> Bartın</a> </p> <a href="https://publications.waset.org/abstracts/66259/semi-natural-vertical-gardens-and-urban-ecology-the-sample-of-bartin-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">366</span> Revitalization Strategy of Beijing-Tianjin-Hebei Rural Areas Organized by Production-Living-Ecology Spatial Network at Township Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liuhui%20Zhu">Liuhui Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Zeng"> Peng Zeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rural revitalization strategy means to take the country and the city on the same level, and achieve urban-rural integration and comprehensive development of rural areas. Beijing-Tianjin-Hebei rural areas have always been the weak links in the region, with prominently uneven development between urban and rural areas. The rural areas need to join the overall regional synergy. Based on the analysis of the characteristics and problems of rural development in the region from the perspective of production-living-ecology space, the paper proposes the township as the basic unit for rural revitalization according to the overall requirements of the rural revitalization strategy. The basic unit helps to realize resource arrangement, functional organization, and collaborative governance organized by the production-living-ecology spatial network. The paper summarizes the planning strategies for the basic unit. Through spatial cognition and spatial reconstruction, the three space is networked through the base, nodes, and connections to improve the comprehensive value of rural areas and achieve the multiple goals of rural revitalization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rural%20revitalization" title="rural revitalization">rural revitalization</a>, <a href="https://publications.waset.org/abstracts/search?q=Beijing-Tianjin-Hebei%20region" title=" Beijing-Tianjin-Hebei region"> Beijing-Tianjin-Hebei region</a>, <a href="https://publications.waset.org/abstracts/search?q=township%20level" title=" township level"> township level</a>, <a href="https://publications.waset.org/abstracts/search?q=production-living-ecology%20spatial%20network" title=" production-living-ecology spatial network"> production-living-ecology spatial network</a> </p> <a href="https://publications.waset.org/abstracts/116760/revitalization-strategy-of-beijing-tianjin-hebei-rural-areas-organized-by-production-living-ecology-spatial-network-at-township-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116760.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">365</span> An Approach for Multilayered Ecological Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20F.%20F.%20Ebecken">N.

The emerging field of 'multilayer networks' provides a natural framework for extending ecological systems analysis to include these multiple layers of complexity as it specifically allows for differentiation and modeling of intralayer and interlayer connectivity. The structure provides a set of concepts and tools that can be adapted and applied to the ecology, facilitating research in high dimensionality, heterogeneous systems in nature. Here, ecological multilayer networks are formally defined based on a review of prior and related approaches, illustrates their application and potential with existing data analyzes, and discusses limitations, challenges, and future applications. The integration of multilayer network theory into ecology offers a largely untapped potential to further address ecological complexity, to finally provide new theoretical and empirical insights into the architecture and dynamics of ecological systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20networks" title="ecological networks">ecological networks</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayered%20networks" title=" multilayered networks"> multilayered networks</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20ecology" title=" sea ecology"> sea ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20Coastal%20Area" title=" Brazilian Coastal Area"> Brazilian Coastal Area</a> </p> <a href="https://publications.waset.org/abstracts/104637/an-approach-for-multilayered-ecological-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">364</span> The Ecological Urbanism as an Oppurtunity to Solve City Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fairuz%20A.%20Ulinnuha">Fairuz A.

Increased numbers of people and cities hand in hand with greater exploitation of world’s resource. Every year, more cities are feeling the devastating of this impact of this situation. During the 1970’s, some of eco-concept were applied to urban settings, one of them is Ecological Cities. A non-profit organization, Urban Ecology, was founded in California in 1975 to 'rebuild cities in balance with nature'. Efforts to synthesize ecological and urban planning approaches were slowed somewhat in the 1980s, but useful refinements were made. Consideration of social impact acknowledges that the ecological design is not just about ecology itself. It is also about questioning and redefining our understanding of the ecology. When ecologist did recognize the existence of cities, they were usually concerned with resource flows. One popular approach was to study the flow and transformation of energy through urban ecosystem. This research method is descriptive method, following LEED Certification which is the international standard of the sustainable building, is more widely applied. But there remains problem that the moral imperative of sustainability and by implication of sustainable design, tends to supplant the disciplinary contribution. Sustainable design is not always seen as design excellence or design innovation. This can provoke the skepticism and cause the tension those who promote disciplinary knowledge and those who push for sustainability. The challenges of rapid urbanization and limited of global resources has become more pressing. So, there is a need to find an alternative design approaches. The urban, as the site of complex relation (economy, political, social, cultural), need a complex problem solving that can solve current and future condition. The aim of this study is to discussed about conjoining of ecology such as public park and sustainable design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecology" title="ecology">ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=cities" title=" cities"> cities</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/92891/the-ecological-urbanism-as-an-oppurtunity-to-solve-city-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92891.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">363</span> Environmental Awareness on Formal Education Level: A Program Approach through Physical Education Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jocelyn%20Floresca">Jocelyn Floresca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aimed to present the by-product of the introduction of environmental ecology awareness on a formal education level utilizing the program course of Physical Education, particularly in the tertiary level. It is based on the premise that the radical need for environmental protection may not only necessarily be the work of people in the pure sciences but also deemed necessary to look into more avenues of the school setting particularly in the field of Physical Education. In the Philippines, most schools’ Physical Education focuses on the advancement of sports, fitness and wellness which are mostly done in the confines of a closed building. The paper dwells into the introduction of Physical Education as an outdoor recreation activity where in the participants of the study had the opportunity to indulge in activities undertaken outside the confines of buildings and going into large areas of the environment. It looked into the individual participant’s environmental social behaviour and effects on the participant’s perceptions in terms of the set objectives of Physical Education before and after the study’s intervention. The study utilized the formal course in Physical Education on nature walks, mountaineering and bird watching as interventions to gain perceptions and understanding. The introduction of the environmental ecology activities as a formal Physical Education course has resulted in deeper awareness that led to understanding the need to protect the environment, appreciation of the value of natural areas and acquiring behaviour for a sustainable use of the environment during the practice of Physical Education. Also, prior to the introduction of environmental ecology in Physical Education as a formal study; participants have no knowledge of what dwells in the identified sites of intervention. Whereas after the study, participants were able to identify various species of birds and plants found in the sites of the study that may lead to further conservation of the particular species. <p
