Loss and fragmentation of habitat threaten red panda population throughout its range, and as a consequence, it is listed as vulnerable on the IUCN Red List of Threatened Species. Despite this pressing situation, data on the ecology of the red panda in western Nepal are lacking. Our aim in the current study was to determine the distribution, associated habitats, and summer diet of the red panda in Dhorpatan Hunting Reserve (DHR), Nepal. Evidence of red pandas was found in all 7 blocks of the reserve, spanning an area of 345.8 km2, between elevations of 2800 m and 4000 m and predominantly (> 75%) in forests comprising plant communities dominated by Abies spectabilis, Acer caesium, Tsuga domusa, and Betula utilis, with ground cover of Arundinaria spp. The dominant plant found in scat of the red panda was Arundinaria spp. (81.7%), with Acer spp., B. utilis, and lichen also frequently present. Livestock grazing and human activities were significantly higher in habitats where signs of pandas were recorded than in areas where they were absent. This habitat overlap between the red panda and livestock potentially poses a major threat to the panda’s survival in the DHR, a fact that should be taken into account in devising management strategies for this threatened species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=red%20panda" title="red panda">red panda</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhorpatan%20hunting%20reserve" title=" Dhorpatan hunting reserve"> Dhorpatan hunting reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=diet" title=" diet"> diet</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20preference" title=" habitat preference"> habitat preference</a> </p> <a href="https://publications.waset.org/abstracts/30309/feeding-ecology-and-habitat-preference-of-red-panda-in-dhorpatan-hunting-reserve-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30309.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">343</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">526</span> Habitat Model Review and a Proposed Methodology to Value Economic Trade-Off between Cage Culture and Habitat of an Endemic Species in Lake Maninjau, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Yuniarti">Ivana Yuniarti</a>, <a href="https://publications.waset.org/abstracts/search?q=Iwan%20Ridwansyah"> Iwan Ridwansyah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper delivers a review of various methodologies for habitat assessment and a proposed methodology to assess an endemic fish species habitat in Lake Maninjau, Indonesia as a part of a Ph.D. project.

The proposed methodology is a generalized linear model (GLM) combined with GIS to assess presence-absence data or habitat suitability index (HSI) combined with the analytical hierarchy process (AHP). Further, a cost of habitat replacement approach is planned to be used to calculate the habitat value as well as its trade-off with the economic value of aquaculture.

Key aspects of the federal species at risk program include the development of recovery documents (recovery strategies, action plans, and management plans) outlining threats, objectives, and broad strategies or measures for conservation or recovery of the species; the identification and protection of critical habitat for threatened and endangered species; and working with groups and organizations to implement on-the-ground recovery actions. Environment Canada’s progress on the development of recovery documents and on the identification and protection of critical habitat in Ontario will be presented, along with successes and challenges associated with on-the ground implementation of recovery actions. In Ontario, Environment Canada is currently involved in several recovery and monitoring programs for at-risk bird species such as the Loggerhead Shrike, Piping Plover, Golden-winged Warbler and Cerulean Warbler and has provided funding for a wide variety of recovery actions targeting priority species at risk and geographic areas each year through stewardship programs including the Habitat Stewardship Program, Aboriginal Fund for Species at Risk, and the Interdepartmental Recovery Fund. Key research needs relevant to the recovery of species at risk have been identified, and include: surveys and monitoring of population sizes and threats, population viability analyses, and addressing knowledge gaps identified for individual species (e.g., species biology and habitat needs). The engagement of all levels of government, the local and international conservation communities, and the scientific research community plays an important role in the conservation and recovery of species at risk in Ontario– through surveying and monitoring, filling knowledge gaps, conducting public outreach, and restoring, protecting, or managing habitat – and will be critical to the continued success of the federal species at risk program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20biology" title="conservation biology">conservation biology</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20protection" title=" habitat protection"> habitat protection</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20at%20risk" title=" species at risk"> species at risk</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20recovery" title=" wildlife recovery"> wildlife recovery</a> </p> <a href="https://publications.waset.org/abstracts/22960/towards-conservation-and-recovery-of-species-at-risk-in-ontario-progress-on-recovery-planning-and-implementation-and-an-overview-of-key-research-needs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22960.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">452</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">524</span> Dynamic Evaluation of Shallow Lake Habitat Quality Based on InVEST Model: A Case in Baiyangdian Lake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shengjun%20Yan">Shengjun Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Wang"> Xuan Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water level changes in a shallow lake always introduce dramatic land pattern changes. To achieve sustainable ecosystem service, it is necessary to evaluate habitat quality dynamic and its spatio-temporal variation resulted from water level changes, which can provide a scientific basis for protection of biodiversity and planning of wetland ecological system. Landsat data in the spring was chosen to obtain landscape data at different times based on the high, moderate and low water level of Baiyangdian Shallow Lake. We used the InVEST to evaluate the habitat quality, habitat degradation, and habitat scarcity. The result showed that: 1) the water level of shallow lake changes from high to low lead to an obvious landscape pattern changes and habitat degradation, 2) the most change area occurred in northwestward and southwest of Baiyangdian Shallow Lake, which there was a 21 percent of suitable habitat and 42 percent of moderately suitable habitat lost. Our findings show that the changes of water level in the shallow lake would have a strong relationship with the habitat quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=habitat%20quality" title="habitat quality">habitat quality</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20degradation" title=" habitat degradation"> habitat degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20level%20changes" title=" water level changes"> water level changes</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20lake" title=" shallow lake"> shallow lake</a> </p> <a href="https://publications.waset.org/abstracts/82753/dynamic-evaluation-of-shallow-lake-habitat-quality-based-on-invest-model-a-case-in-baiyangdian-lake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82753.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">255</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">523</span> Physical Habitat Simulation and Comparison within a Lerma River Reach, with Respect to the Same but Modified Reach, to Create a Linear Park</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garcia-Rodriguez%20Ezequiel">Garcia-Rodriguez Ezequiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20A.%20Ochoa-Franco"> Luis A.

To determine the effect of ecological park construction, on physical habitat of the Lerma river stretch of study, first, the available habitat for the Ictalurus punctatus species was estimated through the simulation of the physical habitat, by using surveying, hydraulics, and habitat information gotten at the river reach in its actual situation. Second, it was estimated the available habitat for the above species, upon the simulation of the physical habitat through the proposed modification for the ecological park creation. Third, it is presented a comparison between both scenarios in terms of available habitat estimated for Ictalurus punctatus species, concluding that in cases of adult and spawning life stages, changes in the channel to create an ecological park would produce a considerable loss of potentially usable habitat (PUH), while in the case of the juvenile life stage PUH remains virtually unchanged, and in the case of life stage fry the PUH would increase due to the presence of velocities and depths of lesser magnitude, due to the presence of minor flow rates and lower volume of the wet channel. It is expected that habitat modification for linear park construction may produce the lack of Ictalurus punktatus species conservation at the river reach of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Habitat%20modification" title="Habitat modification">Habitat modification</a>, <a href="https://publications.waset.org/abstracts/search?q=Ictalurus%20punctatus" title=" Ictalurus punctatus"> Ictalurus punctatus</a>, <a href="https://publications.waset.org/abstracts/search?q=Lerma" title=" Lerma"> Lerma</a>, <a href="https://publications.waset.org/abstracts/search?q=river" title=" river"> river</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20park" title=" linear park"> linear park</a> </p> <a href="https://publications.waset.org/abstracts/29239/physical-habitat-simulation-and-comparison-within-a-lerma-river-reach-with-respect-to-the-same-but-modified-reach-to-create-a-linear-park" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29239.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">475</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">522</span> Urban Sustainable Development Based on Habitat Quality Evolution: A Case Study in Chongqing, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Ren">Jing Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun%20Wu"> Kun Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decade or so, China's urbanization has shown a rapid development trend. At the same time, it has also had a great negative impact on the habitat quality. Therefore, it is of great significance to study the impact of land use change on the level of habitat quality in mountain cities for sustainable urban development. This paper analyzed the spatial and temporal land use changes in Chongqing from 2010 to 2020 using ArcGIS 10.6, as well as the evolutionary trend of habitat quality during this period based on the InVEST 3.13.0, to obtain the impact of land use changes on habitat quality. The results showed that the habitat quality in the western part of Chongqing decreased significantly between 2010 and 2020, while the northeastern and southeastern parts remained stable. The main reason for this is the continuous expansion of urban construction land in the western area, which leads to serious habitat fragmentation and the continuous decline of habitat quality. while, in the northeast and southeast areas, due to the greater emphasis on ecological priority and urban-rural coordination in the development process, land use change is characterized by a benign transfer, which maintains the urbanization process while maintaining the coordinated development of habitat quality. This study can provide theoretical support for the sustainable development of mountain cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mountain%20cities" title="mountain cities">mountain cities</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20environment" title=" ecological environment"> ecological environment</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20quality" title=" habitat quality"> habitat quality</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/175176/urban-sustainable-development-based-on-habitat-quality-evolution-a-case-study-in-chongqing-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175176.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">84</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">521</span> Uneven Habitat Characterisation by Using Geo-Gebra Software in the Lacewings (Insecta: Neuroptera), Knowing When to Calculate the Habitat: Creating More Informative Ecological Experiments </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hakan%20Bozdo%C4%9Fan">Hakan Bozdoğan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A wide variety of traditional methodologies has been enhanced for characterising smooth habitats in order to find out different environmental objectives. The habitats were characterised based on size and shape by using Geo-Gebra Software. In this study, an innovative approach to researching habitat characterisation in the lacewing species, GeoGebra software is utilised. This approach is demonstrated using the example of ‘surface area’ as an analytical concept, wherein the goal was to increase clearness for researchers, and to improve the quality of researching in survey area. In conclusion, habitat characterisation using the mathematical programme provides a unique potential to collect more comprehensible and analytical information about in shapeless areas beyond the range of direct observations methods. This research contributes a new perspective for assessing the structure of habitat, providing a novel mathematical tool for the research and management of such habitats and environments. Further surveys should be undertaken at additional sites within the Amanos Mountains for a comprehensive assessment of lacewings habitat characterisation in an analytical plane.

Two hundred and ten species of Araceae were reported in Thailand, of which 43 species were reported as threatened plants. Fifty percent of endemic status and rare status plants were recorded in limestone areas. Currently, these areas are seriously threatened by land-use changes. The study on taxonomy of Araceous plants was carried out in Lop Buri and Saraburi limestone mountains from February 2011 to May 2015. The purposes of this study were to study species diversity, taxonomic character and ecological habitat. 55 specimens collected from various limestone areas including Pra Phut Tabat National forest (Pra Phut Tabat Mountain, Khao Pra Phut Tabat Noi Mountains, Wat Thum Krabog Mountain), Tab Khwang and Muak Lek Natinal forest (Pha Lad mountain, and Muak Lek waterfall) in Saraburi province ,and Wang Plaeng Ta Muang and Lumnarai National forest (Wat Thum chang phuk mountain), Panead National forest (Wat Khao Samo Khon Mountain), Lan Ta Ridge National forest (Khao Wong Prachan mountain, Wat Pa Chumchon) in Lop Buri province. Twenty species of Araceous plants were identified using characteristics of underground stem, phyllotaxis and leaf blade, spathe and spadix. Species list are Aglaonema cochinchinense, A. simplex, Alocasia acuminata, Amorphophallus paeoniifolius, A. albispathus, A. saraburiensis, A. pseudoharmandii, Pycnospatha arietina, Hapaline kerri, Lasia spinosa, Pothos scandens, Typhonium laoticum, T. orbifolium, T. saraburiense, T. trilobatum, T. sp.1, T. sp. 2, Cryptocoryne crispatula var. balansae, Scindapsus sp., and Rhaphidophora peepla. Five species are new locality records. One species (Typhonium sp.1) is considered as a new species. Seven species were reported as threatened plants in Thailand Red Data Book. Taxonomic features were used for key to species constructions. Araceous specimens were found in mixed deciduous forests, dry evergreen forests with 50-470 m. elevation. New ecological habitat of Typhonium laoticum, T. orbifolium, and T. saraburiense were reported in this study. <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=limestone%20mountains" title=" limestone mountains"> limestone mountains</a>, <a href="https://publications.waset.org/abstracts/search?q=Lopburi%20and%20Saraburi%20provinces" title=" Lopburi and Saraburi provinces"> Lopburi and Saraburi provinces</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20diversity" title=" species diversity"> species diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=taxonomic%20character" title=" taxonomic character"> taxonomic character</a> </p> <a href="https://publications.waset.org/abstracts/46312/taxonomy-of-araceous-plants-on-limestone-mountains-in-lop-buri-and-saraburi-provinces-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46312.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">240</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">518</span> House Price Index Predicts a Larger Impact of Habitat Loss than Primary Productivity on the Biodiversity of North American Avian Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marlen%20Acosta%20Alamo">Marlen Acosta Alamo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Manne"> Lisa Manne</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Veit"> Richard Veit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Habitat loss due to land use change is one of the leading causes of biodiversity loss worldwide. This form of habitat loss is a non-random phenomenon since the same environmental factors that make an area suitable for supporting high local biodiversity overlap with those that make it attractive for urban development. We aimed to compare the effect of two non-random habitat loss predictors on the richness, abundance, and rarity of nature-affiliated and human-affiliated North American breeding birds. For each group of birds, we simulated the non-random habitat loss using two predictors: the House Price Index as a measure of the attractiveness of an area for humans and the Normalized Difference Vegetation Index as a proxy for primary productivity. We compared the results of the two non-random simulation sets and one set of random habitat loss simulations using an analysis of variance and followed up with a Tukey-Kramer test when appropriate. The attractiveness of an area for humans predicted estimates of richness loss and increase of rarity higher than primary productivity and random habitat loss for nature-affiliated and human-affiliated birds. For example, at 50% of habitat loss, the attractiveness of an area for humans produced estimates of richness at least 5% lower and of a rarity at least 40% higher than primary productivity and random habitat loss for both groups of birds. Only for the species abundance of nature-affiliated birds, the attractiveness of an area for humans did not outperform primary productivity as a predictor of biodiversity following habitat loss. We demonstrated the value of the House Price Index, which can be used in conservation assessments as an index of the risks of habitat loss for natural communities. Thus, our results have relevant implications for sustainable urban land-use planning practices and can guide stakeholders and developers in their efforts to conserve local biodiversity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity%20loss" title="biodiversity loss">biodiversity loss</a>, <a href="https://publications.waset.org/abstracts/search?q=bird%20biodiversity" title=" bird biodiversity"> bird biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=house%20price%20index" title=" house price index"> house price index</a>, <a href="https://publications.waset.org/abstracts/search?q=non-random%20habitat%20loss" title=" non-random habitat loss"> non-random habitat loss</a> </p> <a href="https://publications.waset.org/abstracts/163832/house-price-index-predicts-a-larger-impact-of-habitat-loss-than-primary-productivity-on-the-biodiversity-of-north-american-avian-communities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163832.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">86</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">517</span> Species Distribution Modelling for Assessing the Effect of Land Use Changes on the Habitat of Endangered Proboscis Monkey (Nasalis larvatus) in Kalimantan, Indonesia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wardatutthoyyibah">Wardatutthoyyibah</a>, <a href="https://publications.waset.org/abstracts/search?q=Satyawan%20Pudyatmoko"> Satyawan Pudyatmoko</a>, <a href="https://publications.waset.org/abstracts/search?q=Sena%20Adi%20Subrata"> Sena Adi Subrata</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali%20Imron"> Muhammad Ali Imron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The proboscis monkey is an endemic species to the island of Borneo with conservation status IUCN (The International Union for Conservation of Nature) of endangered. The population of the monkey has a specific habitat and sensitive to habitat disturbances. As a consequence of increasing rates of land-use change in the last four decades, its population was reported significantly decreased. We quantified the effect of land use change on the proboscis monkey’s habitat through the species distribution modeling (SDM) approach with Maxent Software. We collected presence data and environmental variables, i.e., land cover, topography, bioclimate, distance to the river, distance to the road, and distance to the anthropogenic disturbance to generate predictive distribution maps of the monkeys. We compared two prediction maps for 2000 and 2015 data to represent the current habitat of the monkey. We overlaid the monkey’s predictive distribution map with the existing protected areas to investigate whether the habitat of the monkey is protected under the protected areas networks. The results showed that almost 50% of the monkey’s habitat reduced as the effect of land use change. And only 9% of the current proboscis monkey’s habitat within protected areas. These results are important for the master plan of conservation of the endangered proboscis monkey and provide scientific guidance for the future development incorporating biodiversity issue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endemic%20species" title="endemic species">endemic species</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20change" title=" land use change"> land use change</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20entropy" title=" maximum entropy"> maximum entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20distribution" title=" spatial distribution"> spatial distribution</a> </p> <a href="https://publications.waset.org/abstracts/101537/species-distribution-modelling-for-assessing-the-effect-of-land-use-changes-on-the-habitat-of-endangered-proboscis-monkey-nasalis-larvatus-in-kalimantan-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101537.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">516</span> Assessing the Nutritional Characteristics and Habitat Modeling of the Comorian’s Yam (Dioscorea comorensis) in a Fragmented Landscape</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mounir%20Soule">Mounir Soule</a>, <a href="https://publications.waset.org/abstracts/search?q=Hindatou%20Saidou"> Hindatou Saidou</a>, <a href="https://publications.waset.org/abstracts/search?q=Razafimahefa"> Razafimahefa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Thani%20Ibouroi"> Mohamed Thani Ibouroi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High levels of habitat fragmentation and loss are the main drivers of plant species extinction. They reduce the habitat quality, which is a determining factor for the reproduction of plant species, and generate strong selective pressures for habitat selection, with impacts on the reproduction and survival of individuals. The Comorian’s yam (Dioscorea comorensis) is one of the most threatened plant species of the Comoros archipelago. The species faces one of the highest rates of habitat loss worldwide (9.3 % per year) and is classified as Endangered in the IUCN red list. Despite the nutritional potential of this tuber, the Comorian’s yam cultivation remains neglected by local populations due probably to lack of knowledge on its nutritional importance and the factors driving its spatial distribution and development. In this study, we assessed the nutritional characteristics of Dioscorea comorensis and the drivers of spatial distribution and abundance to propose conservation measures and improve crop yields. To determine the nutritional characteristics, the Kjeldahl method, the Soxhlet method, and Atwater's specific calorific coefficients methods were applied for analyzing proteins, lipids, and caloric energy respectively. In addition, atomic absorption spectrometry was used to measure mineral particles. By combining species occurrences with ecological (habitat types), climatic (temperature, rainfall, etc.), and physicochemical (soil types and quality) variables, we assessed habitat suitability and spatial distribution of the species and the factors explaining the origin, persistence, distribution and competitive capacity of a species using a Species Distribution Modeling (SDM) method. The results showed that the species contains 83.37% carbohydrates, 6.37% protein, and 0.45% lipids. In 100 grams, the quantities of Calcium, Sodium, Zinc, Iron, Copper, Potassium, Phosphorus, Magnesium, and Manganese are respectively 422.70, 599.41, 223.11, 252.32, 332.20, 780.41, 444.17, 287.71 and 220.73 mg. Its PRAL index is negative (- 9.80 mEq/100 g), and its Ca/P (0.95) and Na/K (0.77) ratios are less than 1. This species provides an energy value of 357.46 Kcal per 100 g, thanks to its carbohydrates and minerals and is distinguished from others by its high protein content, offering benefits for cardiovascular health. According to our SDM, the species has a very limited distribution, restricted to forests with higher biomass, humidity, and clay. Our findings highlight how distribution patterns are related to ecological and environmental factors. They also emphasize how the Comoros yam is beneficial in terms of nutritional quality. Our results represent a basic knowledge that will help scientists and decision-makers to develop conservation strategies and to improve crop yields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dioscorea%20comorensis" title="Dioscorea comorensis">Dioscorea comorensis</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20characteristics" title=" nutritional characteristics"> nutritional characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20distribution%20modeling" title=" species distribution modeling"> species distribution modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation%20strategies" title=" conservation strategies"> conservation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20yields%20improvement" title=" crop yields improvement"> crop yields improvement</a> </p> <a href="https://publications.waset.org/abstracts/189323/assessing-the-nutritional-characteristics-and-habitat-modeling-of-the-comorians-yam-dioscorea-comorensis-in-a-fragmented-landscape" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189323.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">515</span> Ethno-Botanical Survey on the Rare and Endangered Medicinal Plants of Poonch District (Jammu and Kashmir)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shazia%20Shamim">Shazia Shamim</a>, <a href="https://publications.waset.org/abstracts/search?q=Pallavi%20Gautam"> Pallavi Gautam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study describes the presence of rare or endangered plants from Poonch Dist., which spread over 1674 Km sq. located between latitude 330 25' N to 340 01' N and longitude 730 58' E to 740 35' E forming a part of the Northwest Himalaya in Jammu and Kashmir state of India, with the aim of suggesting the strategy for the conservation and promotion of cultivation of rare and endangered medicinal plants, as well as developing traditional knowledge of medicinal plants. The main threats to biodiversity and ecosystem are overexploitation, global climate change, habitat loss, fragmentation, pollution, and invasion of alien species and disturbance of community structure. Surveys were carried out during 2015-2016 throughout the Poonch valley. During the field survey, various criteria of International Union for the conservation of nature for categorizing threatened plants, extent of occurrence, area of occupancy, probability of extinction, etc. were measured. The rarity of species was determined by field study, visual estimations, and literature. During the collection, it was observed that few rare and endangered species which were present in the study area, are also mentioned in the prescribed red data book of Indian plants, International Union for conservation of nature, list of threatened species and list of Botanical Survey of India presented by its Northern Regional Centre. The study was based on extensive surveys of the study area and then concluded by preparing a list of plant species occurring in different seasons, the photographs of all these plant species were collected. Actual threats to the population of a selected plant species in a given area were recorded by direct observation. The present paper provides information about 22 rare and endangered medicinal plant species belonging to 18 families that are used by the native of these areas. Information provided includes botanical name, family name, local name, habitat, part used, ethno medicinal uses and brief preparation of the reported plant species is presented in the present work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20knowledge" title=" traditional knowledge"> traditional knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=International%20Union%20for%20Conservation%20of%20Nature" title=" International Union for Conservation of Nature"> International Union for Conservation of Nature</a>, <a href="https://publications.waset.org/abstracts/search?q=Botanical%20Survery%20of%20India" title=" Botanical Survery of India"> Botanical Survery of India</a> </p> <a href="https://publications.waset.org/abstracts/110532/ethno-botanical-survey-on-the-rare-and-endangered-medicinal-plants-of-poonch-district-jammu-and-kashmir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110532.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">135</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">514</span> Habitat Preference of Lepidoptera (Butterflies), Using Geospatial Analysis in Diyasaru Wetland Park, Western Province, Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiripurage%20Mallika%20Sandamali%20Dissanayaka">Hiripurage Mallika Sandamali Dissanayaka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Butterflies are found everywhere on Earth, helping flowering plants reproduce through pollination. Wetlands perform many valuable functions such as providing wildlife habitat. Diyasaru Wetland Park was chosen as the study site. It is located in a highly urbanized area of Sri Jayawardenepura Kotte, Sri Lanka. A distribution map was prepared to increase butterfly habitat in the urbanized area, and research was conducted to determine the most suitable sections for using it. As this wetland has footpaths for walking, line transect surveys were used to mark species within the sampling area, and directly observed species were recorded. All data collection was done from 0900 to 1200 hours and 1300 to 1600 hours and fieldwork was done from 11 February 2020 to 20 January 2021. ED binoculars (10.5x45), DSLR cameras (Canon EOS/EFS5 mm 3.5-5.6), and Garmin GPS (Etrex 10) were used to observe butterfly species, identify locations, and take photographs as evidence. Analyzing their habitats using GIS (ArcGIS Pro) to identify their distribution within the park premises, the distribution density of the known size of the population was calculated for each point by kernel density, and local similarity values were calculated for each pair of corresponding features through hotspot analysis, and cell values were determined by inverse distance weighting (IDW) using a linearly weighted combination of a set of sample points. According to the maps prepared to predict the distribution of butterflies in this park, the high level of distribution or favorable areas were near flower gardens and meadows, but some individual species prefer habitats that are more suitable for their life activities, so they live in other areas. Sixty-six (66) species belonging to six (6) families have been recorded in the premises. Sixty (60) species of least concern (LC), two (2) near threatened (NT), and four (4) vulnerable (VU) species have been recorded, and several new species, such as Plum Judy (Abisara echerius), were reported. The outcome of the study will form the basis for decision-making by the Sri Lanka Land Development (SLLD) Corporation for the future development and maintenance of the park. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wetland" title="wetland">wetland</a>, <a href="https://publications.waset.org/abstracts/search?q=Lepidoptera" title=" Lepidoptera"> Lepidoptera</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat" title=" habitat"> habitat</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=west" title=" west"> west</a> </p> <a href="https://publications.waset.org/abstracts/182159/habitat-preference-of-lepidoptera-butterflies-using-geospatial-analysis-in-diyasaru-wetland-park-western-province-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182159.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">49</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">513</span> Habitat Suitability, Genetic Diversity and Population Structure of Two Sympatric Fruit Bat Species Reveal the Need of an Urgent Conservation Action</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Thani%20Ibouroi">Mohamed Thani Ibouroi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Cheha"> Ali Cheha</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudine%20Montgelard"> Claudine Montgelard</a>, <a href="https://publications.waset.org/abstracts/search?q=Veronique%20Arnal"> Veronique Arnal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawiyat%20Massoudi"> Dawiyat Massoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillelme%20Astruc"> Guillelme Astruc</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Ali%20Ousseni%20Dhurham"> Said Ali Ousseni Dhurham</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurelien%20Besnard"> Aurelien Besnard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Livingstone's flying fox (Pteropus livingstonii) and the Comorian fruit bat (P.seychellensis comorensis) are two endemic fruit bat species among the mostly threatened animals of the Comoros archipelagos. Despite their role as important ecosystem service providers like all flying fox species as pollinators and seed dispersers, little is known about their ecologies, population genetics and structures making difficult the development of evidence-based conservation strategies. In this study, we assess spatial distribution and ecological niche of both species using Species Distribution Modeling (SDM) based on the recent Ensemble of Small Models (ESMs) approach using presence-only data. Population structure and genetic diversity of the two species were assessed using both mitochondrial and microsatellite markers based on non-invasive genetic samples. Our ESMs highlight a clear niche partitioning of the two sympatric species. Livingstone’s flying fox has a very limited distribution, restricted on steep slope of natural forests at high elevation. On the contrary, the Comorian fruit bat has a relatively large geographic range spread over low elevations in farmlands and villages. Our genetic analysis shows a low genetic diversity for both fruit bats species. They also show that the Livingstone’s flying fox population of the two islands were genetically isolated while no evidence of genetic differentiation was detected for the Comorian fruit bats between islands. Our results support the idea that natural habitat loss, especially the natural forest loss and fragmentation are the important factors impacting the distribution of the Livingstone’s flying fox by limiting its foraging area and reducing its potential roosting sites. On the contrary, the Comorian fruit bats seem to be favored by human activities probably because its diets are less specialized. By this study, we concluded that the Livingstone’s flying fox species and its habitat are of high priority in term of conservation at the Comoros archipelagos scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Comoros%20islands" title="Comoros islands">Comoros islands</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20niche" title=" ecological niche"> ecological niche</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20loss" title=" habitat loss"> habitat loss</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20genetics" title=" population genetics"> population genetics</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20bats" title=" fruit bats"> fruit bats</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation%20biology" title=" conservation biology"> conservation biology</a> </p> <a href="https://publications.waset.org/abstracts/62161/habitat-suitability-genetic-diversity-and-population-structure-of-two-sympatric-fruit-bat-species-reveal-the-need-of-an-urgent-conservation-action" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62161.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">266</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">512</span> Bioclimatic Niches of Endangered Garcinia indica Species on the Western Ghats: Predicting Habitat Suitability under Current and Future Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malay%20K.%20Pramanik">Malay K. Pramanik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, climate change has become a major threat and has been widely documented in the geographic distribution of many plant species. However, the impacts of climate change on the distribution of ecologically vulnerable medicinal species remain largely unknown. The identification of a suitable habitat for a species under climate change scenario is a significant step towards the mitigation of biodiversity decline. The study, therefore, aims to predict the impact of current, and future climatic scenarios on the distribution of the threatened Garcinia indica across the northern Western Ghats using Maximum Entropy (MaxEnt) modelling. The future projections were made for the year 2050 and 2070 with all Representative Concentration Pathways (RCPs) scenario (2.6, 4.5, 6.0, and 8.5) using 56 species occurrence data, and 19 bioclimatic predictors from the BCC-CSM1.1 model of the Intergovernmental Panel for Climate Change’s (IPCC) 5th assessment. The bioclimatic variables were minimised to a smaller number of variables after a multicollinearity test, and their contributions were assessed using jackknife test. The AUC value of 0.956 ± 0.023 indicates that the model performs with excellent accuracy. The study identified that temperature seasonality (39.5 ± 3.1%), isothermality (19.2 ± 1.6%), and annual precipitation (12.7 ± 1.7%) would be the major influencing variables in the current and future distribution. The model predicted 10.5% (19318.7 sq. km) of the study area as moderately to very highly suitable, while 82.60% (151904 sq. km) of the study area was identified as ‘unsuitable’ or ‘very low suitable’. Our predictions of climate change impact on habitat suitability suggest that there will be a drastic reduction in the suitability by 5.29% and 5.69% under RCP 8.5 for 2050 and 2070, respectively. Finally, the results signify that the model might be an effective tool for biodiversity protection, ecosystem management, and species re-habitation planning under future climate change scenarios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garcinia%20Indica" title="Garcinia Indica">Garcinia Indica</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20entropy%20modelling" title=" maximum entropy modelling"> maximum entropy modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=MaxEnt" title=" MaxEnt"> MaxEnt</a>, <a href="https://publications.waset.org/abstracts/search?q=Western%20Ghats" title=" Western Ghats"> Western Ghats</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a> </p> <a href="https://publications.waset.org/abstracts/83845/bioclimatic-niches-of-endangered-garcinia-indica-species-on-the-western-ghats-predicting-habitat-suitability-under-current-and-future-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83845.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">157</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">511</span> Wildlife Habitat Corridor Mapping in Urban Environments: A GIS-Based Approach Using Preliminary Category Weightings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Peters">Stefan Peters</a>, <a href="https://publications.waset.org/abstracts/search?q=Phillip%20Roetman"> Phillip Roetman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global loss of biodiversity is threatening the benefits nature provides to human populations and has become a more pressing issue than climate change and requires immediate attention. While there have been successful global agreements for environmental protection, such as the Montreal Protocol, these are rare, and we cannot rely on them solely. Thus, it is crucial to take national and local actions to support biodiversity. Australia is one of the 17 countries in the world with a high level of biodiversity, and its cities are vital habitats for endangered species, with more of them found in urban areas than in non-urban ones. However, the protection of biodiversity in metropolitan Adelaide has been inadequate, with over 130 species disappearing since European colonization in 1836. In this research project we conceptualized, developed and implemented a framework for wildlife Habitat Hotspots and Habitat Corridor modelling in an urban context using geographic data and GIS modelling and analysis. We used detailed topographic and other geographic data provided by a local council, including spatial and attributive properties of trees, parcels, water features, vegetated areas, roads, verges, traffic, and census data. Weighted factors considered in our raster-based Habitat Hotspot model include parcel size, parcel shape, population density, canopy cover, habitat quality and proximity to habitats and water features. Weighted factors considered in our raster-based Habitat Corridor model include habitat potential (resulting from the Habitat Hotspot model), verge size, road hierarchy, road widths, human density, and presence of remnant indigenous vegetation species. We developed a GIS model, using Python scripting and ArcGIS-Pro Model-Builder, to establish an automated reproducible and adjustable geoprocessing workflow, adaptable to any study area of interest. Our habitat hotspot and corridor modelling framework allow to determine and map existing habitat hotspots and wildlife habitat corridors. Our research had been applied to the study case of Burnside, a local council in Adelaide, Australia, which encompass an area of 30 km2. We applied end-user expertise-based category weightings to refine our models and optimize the use of our habitat map outputs towards informing local strategic decision-making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS%20modeling" title=" GIS modeling"> GIS modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20hotspot" title=" habitat hotspot"> habitat hotspot</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20corridor" title=" wildlife corridor"> wildlife corridor</a> </p> <a href="https://publications.waset.org/abstracts/152993/wildlife-habitat-corridor-mapping-in-urban-environments-a-gis-based-approach-using-preliminary-category-weightings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152993.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">115</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">510</span> The Influence of Forest Management Histories on Dead and Habitat Trees in the Old Growth Forest in Northern Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kiomars%20Sefidi">Kiomars Sefidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dead and habitat tree such as fallen logs, snags, stumps and cracks and loos bark etc. is regarded as an important ecological component of forests on which many forest dwelling species depend, yet its relation to management history in Caspian forest has gone unreported. The aim of research was to compare the amounts of dead tree and habitat in the forests with historically different intensities of management, including: forests with the long term implication of management (PS), the short-term implication of management (NS) which were compared with semi virgin forest (GS). The number of 405 individual dead and habitat trees were recorded and measured at 109 sampling locations. ANOVA revealed volume of the dead tree in the form and decay classes significantly differ within sites and dead volume in the semi virgin forest significantly higher than managed sites. Comparing the amount of dead and habitat tree in three sites showed that dead tree volume related with management history and significantly differ in three study sites. Also, the numbers of habitat trees including cavities, Cracks and loose bark and Fork split trees significantly vary among sites. Reaching their highest in virgin site and their lowest in the site with the long term implication of management, it was concluded that forest management cause reduction of the amount of dead and habitat tree. Forest management history affect the forest's ability to generate dead tree especially in a large size, thus managing this forest according to ecological sustainable principles require a commitment to maintaining stand structure that allow, continued generation of dead tree in a full range of size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest%20biodiversity" title="forest biodiversity">forest biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=cracks%20trees" title=" cracks trees"> cracks trees</a>, <a href="https://publications.waset.org/abstracts/search?q=fork%20split%20trees" title=" fork split trees"> fork split trees</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20management" title=" sustainable management"> sustainable management</a>, <a href="https://publications.waset.org/abstracts/search?q=Fagus%20orientalis" title=" Fagus orientalis"> Fagus orientalis</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/33463/the-influence-of-forest-management-histories-on-dead-and-habitat-trees-in-the-old-growth-forest-in-northern-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33463.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">554</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">509</span> Distribution and Habitat Preference of Red Panda (Ailurus Fulgens Fulgens) in Jumla District, Nepal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saroj%20Panthi">Saroj Panthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sher%20Singh%20Thagunna"> Sher Singh Thagunna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliable and sufficient information regarding status, distribution and habitat preference of red panda (Ailurus fulgens fulgens) is lacking in Nepal. The research activities on red panda in the mid-western Nepal are very limited, so the status of red panda in the region is quite unknown. The study conducted during May, 2013 in three Village Development Committees (VDCs) namely Godhemahadev, Malikathata and Tamti of Jumla district was an important step for providing vital information including distribution and habitat preference of this species. The study included the reconnaissance, key informants survey, interviews, and consultation for the most potential area identification, opportunistic survey comprising the direct observation and indirect sign count method for the presence and distribution, habitat assessment consisting vegetation sampling and ocular estimation. The study revealed the presence of red panda in three forests namely Bahirepatan, Imilchadamar and Tyakot of Godhemahadev, Tamti and Malikathata VDCs respectively. The species was found distributed between 2880 and 3244 m with an average dropping encounter rate of 1.04 per hour of searching effort and 12 pellets per dropping. Red panda mostly preferred the habitat in the elevation range of 2900 - 3000 m with southwest facing steep slopes (36˚ - 45˚), associated with water sources at the distance of ≤100 m. Trees such as Acer spp., Betula utilis and Quercus semecarpifolia, shrub species of Elaeagnus parvifolia, Drepanostachyum spp. and Jasminum humile, and the herbs like Polygonatum cirrhifolium, Fragaria nubicola and Galium asperifolium were found to be the most preferred species by red panda. The red panda preferred the habitat with dense crown coverage ( >20% - 100%) and 31% - 50% ground cover. Fallen logs (39%) were the most preferred substrate used for defecation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution" title="distribution">distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20preference" title=" habitat preference"> habitat preference</a>, <a href="https://publications.waset.org/abstracts/search?q=jumla" title=" jumla"> jumla</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20panda" title=" red panda"> red panda</a> </p> <a href="https://publications.waset.org/abstracts/29668/distribution-and-habitat-preference-of-red-panda-ailurus-fulgens-fulgens-in-jumla-district-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29668.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">309</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">508</span> Designing Bird-Friendly Kolkata city</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madhumita%20Roy">Madhumita Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kolkata, the city of joy, is an organic city with 45 lakhs of people till date. The increasing population stress is creating a constant pressure on the ground surface which in turn reducing the possible area for plantation. Humans, plants, and birds have a mutualistic relationship, and all are dependent on each other for their survival. Vegetation structure is very important for a bird life because it can be used as a residence, foraging, life cycle, and shelter from predators. On the other hand, in urban areas, buildings and structures also plays a major role for birds habitat w.r.t, nesting, resting, etc. City birds are constantly upgrading their adaptative mechanism with changing urban pattern with modern architectural designs. Urbanisation and unplanned development lead to environmental degradation and bird habitat fragmentation, which have impacts on the degradation of the quality and quantity of bird habitat. Declining green cover and habitat loss affects the diversity and population structure of birds. Their reducing number is an increasing threat not only to the bird community but also to the city as birds are considered as one of the most important environmental indicator. This study aims to check the present avian status like species richness, relative abundance, and diversity of bird species in the context of changing urban pattern in Kolkata city. Nesting strategy in the urban habitat of the avian community is another avenue of interest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urbanisation" title="urbanisation">urbanisation</a>, <a href="https://publications.waset.org/abstracts/search?q=avian%20species" title=" avian species"> avian species</a>, <a href="https://publications.waset.org/abstracts/search?q=kolkata%20metropolis" title=" kolkata metropolis"> kolkata metropolis</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a> </p> <a href="https://publications.waset.org/abstracts/154202/designing-bird-friendly-kolkata-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154202.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">100</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">507</span> The Influence of Environment Characteristics in the Distribution of Vegetation Communities in Rawdhat Salasil, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suliman%20Mohammed%20Alghanem">Suliman Mohammed Alghanem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecological and botanical surveys were conducted on Rawdhat Salasil, Al-Qassim region, Saudi Arabia.

Therefore, optimal management of ungulates populations permits harbouring of viable large carnivore populations within protected areas. Ungulate density is likely to respond to regimes of protection and vegetation types. This has generated the need among conservation practitioners to obtain strata specific seasonal species densities for habitat management. Kanha Tiger Reserve (KTR) of 2074 km2 area comprises of two distinct management strata: The core (940 km2), devoid of human settlements and buffer (1134 km2) which is a multiple use area. In general, four habitat strata, grassland, sal forest, bamboo-mixed forest and miscellaneous forest are present in the reserve. Stratified sampling approach was used to access a) impact of human use and b) effect of habitat and season on ungulate densities. Since 2013 to 2016, ungulates were surveyed in winter and summer of each year with an effort of 1200 km walk in 200 spatial transects distributed throughout Kanha Tiger Reserve. We used a single detection function for each species within each habitat stratum for each season for estimating species specific seasonal density, using program DISTANCE. Our key results state that the core area had 4.8 times higher wild ungulate biomass compared with the buffer zone, highlighting the importance of undisturbed area. Chital was found to be most abundant, having a density of 30.1(SE 4.34)/km2 and contributing 33% of the biomass with a habitat preference for grassland. Unlike other ungulates, Gaur being mega herbivore, showed a major seasonal shift in density from bamboo-mixed and sal forest in summer to miscellaneous forest in winter. Maximum diversity and ungulate biomass were supported by grassland followed by bamboo-mixed habitat. Our study stresses the importance of inviolate core areas for achieving high wild ungulate densities and for maintaining populations of endangered and rare species. Grasslands accounts for 9% of the core area of KTR maintained in arrested stage of succession, therefore enhancing this habitat would maintain ungulate diversity, density and cater to the needs of only surviving population of the endangered barasingha and grassland specialist the blackbuck. We show the relevance of different habitat types for differential seasonal use by ungulates and attempt to interpret this in the context of nutrition and cover needs by wild ungulates. Management for an optimal habitat mosaic that maintains ungulate diversity and maximizes ungulate biomass is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distance%20sampling" title="distance sampling">distance sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20management" title=" habitat management"> habitat management</a>, <a href="https://publications.waset.org/abstracts/search?q=ungulate%20biomass" title=" ungulate biomass"> ungulate biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a> </p> <a href="https://publications.waset.org/abstracts/60899/effect-of-human-use-season-and-habitat-on-ungulate-densities-in-kanha-tiger-reserve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60899.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">303</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">504</span> Nesting Habitat Preference of Indigenous Bumblebee, Bombus haemorrhoidalis in Himalayan Range of Azad Jammu and Kashmir, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umer%20Ayyaz%20Aslam%20Sheikh">Umer Ayyaz Aslam Sheikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non Apis bee like the bumblebees are important due to their utilization of diverse floral plants and belong to the richest and most conspicuous flower visitors in alpine, temperate and arctic environments for pollination in both natural and managed cropping systems. These bees generally construct underground nests and habitat devastation and crumbling are major causes for their decline in nature. The present study was conducted in the Himalayan range of Azad Jammu, and Kashmir, Pakistan, surveys were conducted during the early spring season to observe maximum Bombus haemorrhoidalis queens (emerged after winter diapauses) searching for a nesting place. Whole study area was grouped into four types of landscape (open field, relatively open , relatively wooded and wooded), five habitat types (field, field boundary, pasture forest boundary and forest) and these habitat further grouped into four different patch types including withered grass, new grass, tussocks and stones and moss. Maximum nest seeking bumblebee queens preferred relatively open field landscape followed by open fields and forest boundaries. Field boundaries were recorded as most proffered habitat along with withered grasses for nesting sites of B. haemorrhoidalis queens.

Osmoderma inhabits cavities containing sufficient volume of wood mould usually caused by brown rot in veteran deciduous trees. As the species, having high demands for the habitat quality, they indicate the suitability of the habitat for a number of other specialized saproxylic species. Since typical habitat needed for Osmoderma and other species associated with hollow veteran trees is rapidly declining, the species complex is protected under various legislation, such as Bern Convention, EU Habitats Directive and the Red Lists of many European states. Natura 2000 sites are the main tool for conservation of O. barnabita in Lithuania, currently 17 Natura 2000 sites are designated for the species, where monitoring is implemented once in 3 years according to the approved methodologies. Despite these monitoring efforts in species reports, provided to EU according to the Article 17 of the Habitats Directive, it is defined on the national level, that overall assessment of O. barnabita is inadequate and future prospects are poor. Therefore, research on the distribution and habitat status of O. barnabita was launched on the national level in 2016, which was complemented by preparatory actions of LIFE OSMODERMA project. The research was implemented in the areas equally distributed in the whole area of Lithuania, where O. barnabita was previously not observed, or not observed in the last 10 years. 90 areas, such as Habitats of European importance (9070 Fennoscandian wooded pastures, 9180 Tilio-Acerion forests of slopes, screes, and ravines), Woodland key habitats (B1 broad-leaved forest, K1 single giant tree) and old manor parks, were chosen for the research after review of habitat data from the existing national databases. The first part of field inventory of the habitats was carried out in 2016 and 2017 autumn and winter seasons, when relative abundance of O. barnabita was estimated according to larval faecal pellets in the tree cavities or around the trees. The state of habitats was evaluated according to the density of suitable and potential trees, percentage of not overshadowed trees and amount of undergrowth. The second part of the field inventory was carried out in the summer with pheromone traps baited with (R)-(+)-γ –decalactone. Results of the research show not only occurrence and habitat status of O. barnabita, but also help to clarify O. barnabita habitat requirements in Lithuania, define habitat size, its structure and distribution. Also, it compares habitat needs between the regions in Lithuania and inside and outside Natura 2000 areas designated for the species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=habitat%20status" title="habitat status">habitat status</a>, <a href="https://publications.waset.org/abstracts/search?q=insect%20conservation" title=" insect conservation"> insect conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=Osmoderma%20barnabita" title=" Osmoderma barnabita"> Osmoderma barnabita</a>, <a href="https://publications.waset.org/abstracts/search?q=veteran%20trees" title=" veteran trees"> veteran trees</a> </p> <a href="https://publications.waset.org/abstracts/89540/occurrence-and-habitat-status-of-osmoderma-barnabita-in-lithuania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89540.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">137</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">502</span> Ecological Study of Habitat Conditions and Distribution of Cistanche tubulosa (Rare Plant Species) in Pakpattan District, Pakistan </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shumaila%20Shakoor">Shumaila Shakoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> C. tubulosa is a rare parasitic plant. It is found to be endangered and it acquires nutrition by penetrating roots deep in host roots. It has momentous potential to fulfill local and national health needs. This specie became endangered due to its parasitic mode of life and lack of awareness. Investigation of distribution and habitat conditions of C. tubulosa from District Pakpattan is the objective of this study. To explore its habitat conditions and community ecology phytosociological survey of C. tubulosa in different habitats i.e roadsides and graveyards was carried out. It was found that C. tubulosa occurs successfully in different habitats like graveyards and roadsides with specific neighboring species. Soil analysis was carried out by taking soil samples from seven sites. Soil was analyzed for pH, EC, soil texture, OM, N %age, Ca, Mg, P and K, which shows that soil of C. tubulosa is rich in all these nutrients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title="organic matter">organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium" title=" potassium"> potassium</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a> </p> <a href="https://publications.waset.org/abstracts/55645/ecological-study-of-habitat-conditions-and-distribution-of-cistanche-tubulosa-rare-plant-species-in-pakpattan-district-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55645.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">196</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">501</span> River Habitat Modeling for the Entire Macroinvertebrate Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pinna%20Beatrice.">Pinna Beatrice.</a>, <a href="https://publications.waset.org/abstracts/search?q=Laini%20Alex"> Laini Alex</a>, <a href="https://publications.waset.org/abstracts/search?q=Negro%20Giovanni"> Negro Giovanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Burgazzi%20Gemma"> Burgazzi Gemma</a>, <a href="https://publications.waset.org/abstracts/search?q=Viaroli%20Pierluigi"> Viaroli Pierluigi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vezza%20Paolo"> Vezza Paolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Habitat models rarely consider macroinvertebrates as ecological targets in rivers. Available approaches mainly focus on single macroinvertebrate species, not addressing the ecological needs and functionality of the entire community. This research aimed to provide an approach to model the habitat of the macroinvertebrate community. The approach is based on the recently developed Flow-T index, together with a Random Forest (RF) regression, which is employed to apply the Flow-T index at the meso-habitat scale. Using different datasets gathered from both field data collection and 2D hydrodynamic simulations, the model has been calibrated in the Trebbia river (2019 campaign), and then validated in the Trebbia, Taro, and Enza rivers (2020 campaign). The three rivers are characterized by a braiding morphology, gravel riverbeds, and summer low flows. The RF model selected 12 mesohabitat descriptors as important for the macroinvertebrate community. These descriptors belong to different frequency classes of water depth, flow velocity, substrate grain size, and connectivity to the main river channel. The cross-validation R² coefficient (R²𝒸ᵥ) of the training dataset is 0.71 for the Trebbia River (2019), whereas the R² coefficient for the validation datasets (Trebbia, Taro, and Enza Rivers 2020) is 0.63. The agreement between the simulated results and the experimental data shows sufficient accuracy and reliability. The outcomes of the study reveal that the model can identify the ecological response of the macroinvertebrate community to possible flow regime alterations and to possible river morphological modifications. Lastly, the proposed approach allows extending the MesoHABSIM methodology, widely used for the fish habitat assessment, to a different ecological target community. Further applications of the approach can be related to flow design in both perennial and non-perennial rivers, including river reaches in which fish fauna is absent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20flows" title="ecological flows">ecological flows</a>, <a href="https://publications.waset.org/abstracts/search?q=macroinvertebrate%20community" title=" macroinvertebrate community"> macroinvertebrate community</a>, <a href="https://publications.waset.org/abstracts/search?q=mesohabitat" title=" mesohabitat"> mesohabitat</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20habitat%20modeling" title=" river habitat modeling"> river habitat modeling</a> </p> <a href="https://publications.waset.org/abstracts/164056/river-habitat-modeling-for-the-entire-macroinvertebrate-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164056.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">94</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">500</span> A Study of the Relationship between Habitat Patch Metrics and Landscape Connectivity with Reference to Colombo Wetlands Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20E.%20M.%20W.%20G.%20M.%20K.%20Ekanayake">H.

Urban Wetlands are the most vulnerable ecosystem effects from the fragmentation. Therefore, management of landscape connectivity with proper analysis and understanding has become a most important measure for urban wetland habitats. This study aimed to introduce spatial planning strategy to identify and locate landscape developments appropriately in order to restore landscape connectivity. Therefore, the study focuses on understanding the relationship between habitat patch metrics and landscape connectivity with reference to Colombo wetlands. Geographic Information Systems (GIS) was used to measure the wetland patch metrics; Patch area, Total edge, Perimeter-area ratio, Core area index and Inter-patch distances. Further, GIS-enabled least-cost path tool was used to measure the Landscape connectivity and calculate the number of species flow paths per wetland patch. According to the research findings; increasing the patch area, maintaining a mean perimeter-area ratio and core area index also reducing the inter-patch distances could enhance the landscape connectivity. Further, this study introduces three patch typologies; ‘active patches,' ‘open patches’ and ‘closed patches’ that severs to landscape connectivity in different levels. In the end, the study proposes a strategy for Landscape Architects to select most suitable locations to implement ecological based landscape developments with adjacent to the existing urban habitat in order to enhance habitat patch metrics and to restore the landscape connectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landscape%20fragmentation" title="landscape fragmentation">landscape fragmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20wetlands" title=" urban wetlands"> urban wetlands</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20connectivity" title=" landscape connectivity"> landscape connectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20metrics" title=" patch metrics"> patch metrics</a> </p> <a href="https://publications.waset.org/abstracts/82563/a-study-of-the-relationship-between-habitat-patch-metrics-and-landscape-connectivity-with-reference-to-colombo-wetlands-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82563.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">204</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">499</span> Ecological Evaluation and Conservation Strategies of Economically Important Plants in Indian Arid Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sher%20Mohammed">Sher Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Purushottam%20Lal"> Purushottam Lal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pawan%20K.%20Kasera"> Pawan K.

This desert is spreading over 12 districts having a rich source of economically important/threatened plant diversity interacting and growing with adverse climatic conditions of the area. Due to variable geological, physiographic, climatic, edaphic and biotic factors, the arid zone medicinal flora exhibit a wide collection of angiosperm families. The herbal diversity of this arid region is medicinally important in household remedies among tribal communities as well as in traditional systems. The on-going increasing disturbances in natural ecosystems are due to climatic and biological, including anthropogenic factors. The unique flora and subsequently dependent faunal diversity of the desert ecosystem is losing its biotic potential. A large number of plants have no future unless immediate steps are taken to arrest the causes, leading to their biological improvement. At present the potential loss in ecological amplitude of various genera and species is making several plant species as red listed plants of arid zone vegetation such as Commmiphora wightii, Tribulus rajasthanensis, Calligonum polygonoides, Ephedra foliata, Leptadenia reticulata, Tecomella undulata, Blepharis sindica, Peganum harmala, Sarcostoma vinimale, etc. Mostly arid zone species are under serious pressure against prevailing ecosystem factors to continuation their life cycles. Genetic, molecular, cytological, biochemical, metabolic, reproductive, germination etc. are the several points where the floral diversity of the arid zone area is facing severe ecological influences. So, there is an urgent need to conserve them. There are several opportunities in the field to carry out remarkable work at particular levels to protect the native plants in their natural habitat instead of only their in vitro multiplication. <p
