Impacts of alien species on public health have received a degree of attention worldwide, largely in developed countries, but scarce in developing countries. Here, we provide a review of human exposures and poisonings cases from native and alien plant species reported to poison information centers. A retrospective review of the Tygerberg Poison Information Centre (TPIC) and Poisons Information Centre (PIC) at Red Cross War Memorial Children's Hospital (RCWMCH) was conducted over approximately 2-year period (1 June 2015 through to 06 March 2017). Combined, TPIC and PIC handled 626 cases during the 2-year period. Toxicity cases were more abundant in Gauteng (47.1%), followed by Western Cape (29.4%). The primary mechanism of injury was ingestion (96.7%), and all cases were predominantly accidental. Most reported cases involved infants (20.6%), with few fully-grown adults related cases (5.8%). Adults presented minor to moderate toxicity, while infants none to minor toxicity. We conclude that reported toxicity cases on human health are biased towards few alien species and that several cases relate to unknown species of mushrooms. Public awareness is essential to reducing the poisoning incidences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alien%20species" title="alien species">alien species</a>, <a href="https://publications.waset.org/abstracts/search?q=poisoning" title=" poisoning"> poisoning</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20species" title=" invasive species"> invasive species</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/82084/the-retrospective-investigation-of-the-impacts-of-alien-taxa-on-human-health-a-case-study-of-two-poison-information-centers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82084.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">185</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">3210</span> Climate Change and the Invasive Alien Species of Western Himalayan State of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yashasvi%20Thakur">Yashasvi Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikas%20K.%20Sharma"> Vikas K.

A total of 297 naturalized alien plant species belonging to 65 families in the IHR have already been reported. Of the total 297 naturalized alien plant species in IHR, the maximum species occur in Himachal Pradesh (232; 78.1%), followed by Jammu & Kashmir (192; 64.6%) and Uttarakhand (181; 60.90%). The present study reports the spread of some invasive and existing weed species like Ageratum conyzoides, Bidens pilosa, Chromolaena odorata, Lantana camara, Brossnetia papyrifera, Oxalis corniculata, Galinsoga parviflora, Panicum maximum at an extent that they are not only invading the agricultural fields but are also replacing the native plant species and degrading the existing grassland quality. Moreover, the degradation of grassland has led to the dry fodder shortage for livestock in the lower Shivalik ranges of the state of Himachal Pradesh and has also encouraged the use of herbicides at an extensive scale. This article provides a mapping of the current spread of some of these species at the block level to allow the development of appropriate management strategies and policy planning for addressing issues pertaining to plant invasion, agricultural fields, and grasslands across the IHR states. <p class="card-text"><strong>Keywords:</strong> <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=invasive%20alien%20species" title=" invasive alien species"> invasive alien species</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=grassland" title=" grassland"> grassland</a>, <a href="https://publications.waset.org/abstracts/search?q=IHR" title=" IHR"> IHR</a> </p> <a href="https://publications.waset.org/abstracts/174947/climate-change-and-the-invasive-alien-species-of-western-himalayan-state-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174947.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">74</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">3209</span> Quality of Work Life of Alien Workers in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chetsada%20Noknoi">Chetsada Noknoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to study the quality of life of alien workers in Thailand and to compare the quality of work life of alien workers based on personal factors and work factors.

Non-native fish species can displace native fish species through competition, predation, disrupting spawning, transforming ecosystems, or transmitting parasites. This influence is more and more noticeable in Poland and in the world. From December 2014 to October 2020, did catch of fishes by electrofishing method carried on 416 sites in various parts of Poland. Research was conducted in both running and stagnant freshwaters with the predominance of running waters. Only sites where the presence of fish was found were analysed. The research covered a wide spectrum of waters from small mountain streams, through drainage ditches to the largest Polish river - the Vistula. Single sites covered oxbow lakes, small ponds and lakes. Electrofishing was associated with ichthyofauna inventories and was mainly aimed at detecting protected species of fish and lampreys or included in the annexes to the EU Habitats Directive (Council Directive 92/43/EEC on the Conservation of natural habitats and of wild fauna and flora). The results of these catches were analysed for alien and invasive fish species. The analysis of the catch structure shows that in 71 out of 416 research sites was found alien and invasive fish species, belonging to 9 taxa. According to the above, alien species of fish are present in 17% of the study sites. The most frequently observed species was the Prussian carp Carassius gibelio, which was recorded on 43 sites. Stone moroko Pseudorasbora parva was found on 24 sites. Chinese sleeper Perccottus glenii was found on 6 sites, and Bullhead Ameiurus sp. was also found on 6 sites. Western tubenose goby Proterorhinus semilunaris was found at 5 sites and Rainbow trout Oncorhynchus mykiss at 3 sites. Monkey goby Neogobius fluviatilis, Round goby Neogobius melanostomus and Eurasian carp Cyprinus carpio was recorded on 2 sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-native%20species" title="non-native species">non-native species</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20species" title=" invasive species"> invasive species</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20species" title=" fish species"> fish species</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20fish%20species" title=" invasive fish species"> invasive fish species</a>, <a href="https://publications.waset.org/abstracts/search?q=native%20fish%20species" title=" native fish species"> native fish species</a> </p> <a href="https://publications.waset.org/abstracts/157318/non-native-and-invasive-fish-species-in-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157318.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">110</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">3207</span> Rapid and Long-term Alien Language Analysis - Forming Frameworks for the Interpretation of Alien Communication for More Intelligent Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samiksha%20Raviraja">Samiksha Raviraja</a>, <a href="https://publications.waset.org/abstracts/search?q=Junaid%20Arif"> Junaid Arif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important abilities in species is the ability to communicate. This paper proposes steps to take when and if aliens came in contact with humans, and how humans would communicate with them. The situation would be a time-sensitive scenario, meaning that communication is at the utmost importance if such an event were to happen. First, humans would need to establish mutual peace by conveying that there is no threat to the alien race. Second, the aliens would need to acknowledge this understanding and reciprocate. This would be extremely difficult to do regardless of their intelligence level unless they are very human-like and have similarities to our way of communicating. The first step towards understanding their mind is to analyze their level of intelligence - Level 1-Low intelligence, Level 2-Human-like intelligence or Level 3-Advanced or High Intelligence. These three levels go hand in hand with the Kardashev scale. Further, the Barrow scale will also be used to categorize alien species in hopes of developing a common universal language to communicate in. This paper will delve into how the level of intelligence can be used toward achieving communication with aliens by predicting various possible scenarios and outcomes by proposing an intensive categorization system. This can be achieved by studying their Emotional and Intelligence Quotient (along with technological and scientific knowledge/intelligence). The limitations and capabilities of their intelligence must also be studied. By observing how they respond and react (expressions and senses) to different kinds of scenarios, items and people, the data will help enable good categorisation. It can be hypothesised that the more human-like aliens are or can relate to humans, the more likely it is that communication is possible. Depending on the situation, either human can teach aliens a human language, or humans can learn an alien language, or both races work together to develop a mutual understanding or mode of communication. There are three possible ways of contact. Aliens visit Earth, or humans discover aliens while on space exploration or through technology in the form of signals. A much rarer case would be humans and aliens running into each other during a space expedition of their own. The first two possibilities allow a more in-depth analysis of the alien life and enhanced results compared. The importance of finding a method of talking with aliens is important in order to not only protect Earth and humans but rather for the advancement of Science through the shared knowledge between the two species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligence" title="intelligence">intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=Kardashev%20scale" title=" Kardashev scale"> Kardashev scale</a>, <a href="https://publications.waset.org/abstracts/search?q=Barrow%20scale" title=" Barrow scale"> Barrow scale</a>, <a href="https://publications.waset.org/abstracts/search?q=alien%20civilizations" title=" alien civilizations"> alien civilizations</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20and%20intelligence%20quotient" title=" emotional and intelligence quotient"> emotional and intelligence quotient</a> </p> <a href="https://publications.waset.org/abstracts/161879/rapid-and-long-term-alien-language-analysis-forming-frameworks-for-the-interpretation-of-alien-communication-for-more-intelligent-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161879.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">72</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">3206</span> Inhibitory Effects of Ambrosia trifida L. on the Development of Root Hairs and Protein Patterns of Radicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Hyon%20Kil">Ji-Hyon Kil</a>, <a href="https://publications.waset.org/abstracts/search?q=Kew-Cheol%20Shim"> Kew-Cheol Shim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Ae%20Park"> Kyoung-Ae Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungho%20Kim"> Kyoungho Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ambrosia trifida L. is designated as invasive alien species by the Act on the Conservation and Use of Biodiversity by the Ministry of Environment, Korea.

This study was conducted to determine the distribution and abundance of alien invasive trees in Nyika National Park (NNP). Data on species' presence and abundance were collected from belt transects (n=31) in a 100 square kilometer area on the central plateau. The data were tested for normality using the Shapiro-Wilk test; Mann-Whitney test was carried out to compare frequencies and abundances between the species, and geographical information systems were used for spatial analyses. Results revealed that Black Wattle (Acacia mearnsii), Mexican Pine (Pinus patula) and Himalayan Raspberry (Rubus ellipticus) were the main alien invasive trees on the plateau. A. mearnsii was localized in the areas where it was first introduced, whereas P. patula and R. ellipticus were spread out beyond original points of introduction. R. ellipticus occurred as dense, extensive (up to 50 meters) thickets on the margins of forest patches and pine stands, whilst P. patula trees were frequent in the valleys, occurring most densely (up to 39 stems per 100 square meters) south-west of Chelinda camp on the central plateau with high variation in tree heights. Additionally, there were no significant differences in abundance between R. ellipticus (48) and P. patula (48) in the study area (p > 0.05) It was concluded that R. ellipticus and P. patula require more attention as compared to A. mearnsii. Howbeit, further studies into the invasion ecology of both P. patula and R. ellipticus on the Nyika plateau are highly recommended so as to assess the threat posed by the species on biodiversity, and recommend appropriate conservation measures in the national park. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alien-invasive%20trees" title="alien-invasive trees">alien-invasive trees</a>, <a href="https://publications.waset.org/abstracts/search?q=Himalayan%20raspberry" title=" Himalayan raspberry"> Himalayan raspberry</a>, <a href="https://publications.waset.org/abstracts/search?q=Nyika%20National%20Park" title=" Nyika National Park"> Nyika National Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexican%20pine" title=" Mexican pine"> Mexican pine</a> </p> <a href="https://publications.waset.org/abstracts/99850/status-of-alien-invasive-trees-on-the-grassland-plateau-in-nyika-national-park" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99850.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">205</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">3204</span> Colonization of Non-Planted Mangrove Species in the “Rehabilitation of Aquaculture Ponds to Mangroves” Projects in China </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanmei%20Xiong">Yanmei Xiong</a>, <a href="https://publications.waset.org/abstracts/search?q=Baowen%20Liao"> Baowen Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun%20Xin"> Kun Xin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhongmao%20Jiang"> Zhongmao Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Guo"> Hao Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujun%20Chen"> Yujun Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei%20Li"> Mei Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conversion of mangroves to aquaculture ponds represented as one major reason for mangrove loss in Asian countries in the 20th century.

In this study, a total of 17 rehabilitation sites in Dongzhai Bay, Hainan, China were surveyed for vegetation, soil and surface elevation five years after the rehabilitation project was initiated. Colonization of non-planted mangrove species was found at all sites and non-planted species dominated over planted species at 14 sites. Mangrove plants could only be found within the elevation range of -20 cm to 65 cm relative to the mean sea level. Soil carbon and nitrogen contents of the top 20 cm were generally low, ranging between 0.2%–1.4% and 0.03%–0.09%, respectively, and at each site, soil carbon and nitrogen were significantly lower at elevations with mangrove plants than lower elevations without mangrove plants. Seven sites located at the upper stream of river estuaries, where soil salinity was relatively lower, and nutrient was relatively higher, was dominated by non-planted Sonneratia caseolaris. Seven sites located at the down-stream of river estuaries or in the inner part of the bay, where soil salinity and nutrient were intermediate, were dominated by non-planted alien Sonneratia apetala. Another three sites located at the outer part of the bay, where soil salinity was higher and nutrient was lower, were dominated by planted species (Rhizophora stylosa, Kandelia obovata, Aegiceras corniculatum and Bruguiera sexangula) with non-planted S. apetala and Avicennia marina also found. The results suggest that natural colonization of mangroves is feasible in pond rehabilitation projects given the rehabilitation of tidal activities and appropriate elevations. Surface elevation is the major determinate for the success of mangrove rehabilitation, and soil salinity and nutrients are important in shaping vegetation structure. The colonization and dominance of alien species (Sonneratia apetala in this case) in some rehabilitation sites poses invasion risks and thus cautions should be taken when introducing alien mangrove species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20wetlands" title="coastal wetlands">coastal wetlands</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20restoration" title=" ecological restoration"> ecological restoration</a>, <a href="https://publications.waset.org/abstracts/search?q=mangroves" title=" mangroves"> mangroves</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20colonization" title=" natural colonization"> natural colonization</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20pond%20rehabilitation" title=" shrimp pond rehabilitation"> shrimp pond rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=wetland%20restoration" title=" wetland restoration"> wetland restoration</a> </p> <a href="https://publications.waset.org/abstracts/115643/colonization-of-non-planted-mangrove-species-in-the-rehabilitation-of-aquaculture-ponds-to-mangroves-projects-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115643.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">134</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">3203</span> Evaluation of Invasive Tree Species for Production of Phosphate Bonded Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Osakue%20Amiandamhen">Stephen Osakue Amiandamhen</a>, <a href="https://publications.waset.org/abstracts/search?q=Schwaller%20Andreas"> Schwaller Andreas</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Meincken"> Martina Meincken</a>, <a href="https://publications.waset.org/abstracts/search?q=Luvuyo%20Tyhoda"> Luvuyo Tyhoda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Invasive alien tree species are currently being cleared in South Africa as a result of the forest and water imbalances. These species grow wildly constituting about 40% of total forest area. They compete with the ecosystem for natural resources and are considered as ecosystem engineers by rapidly changing disturbance regimes. As such, they are harvested for commercial uses but much of it is wasted because of their form and structure. The waste is being sold to local communities as fuel wood. These species can be considered as potential feedstock for the production of phosphate bonded composites. The presence of bark in wood-based composites leads to undesirable properties, and debarking as an option can be cost implicative. This study investigates the potentials of these invasive species processed without debarking on some fundamental properties of wood-based panels. Some invasive alien tree species were collected from EC Biomass, Port Elizabeth, South Africa. They include Acacia mearnsii (Black wattle), A. longifolia (Long-leaved wattle), A. cyclops (Red-eyed wattle), A. saligna (Golden-wreath wattle) and Eucalyptus globulus (Blue gum). The logs were chipped as received. The chips were hammer-milled and screened through a 1 mm sieve. The wood particles were conditioned and the quantity of bark in the wood was determined. The binding matrix was prepared using a reactive magnesia, phosphoric acid and class S fly ash. The materials were mixed and poured into a metallic mould. The composite within the mould was compressed at room temperature at a pressure of 200 KPa. After initial setting which took about 5 minutes, the composite board was demoulded and air-cured for 72 h. The cured product was thereafter conditioned at 20°C and 70% relative humidity for 48 h. Test of physical and strength properties were conducted on the composite boards. The effect of binder formulation and fly ash content on the properties of the boards was studied using fitted response surface technology, according to a central composite experimental design (CCD) at a fixed wood loading of 75% (w/w) of total inorganic contents. The results showed that phosphate/magnesia ratio of 3:1 and fly ash content of 10% was required to obtain a product of good properties and sufficient strength for intended applications. The proposed products can be used for ceilings, partitioning and insulating wall panels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invasive%20alien%20tree%20species" title="invasive alien tree species">invasive alien tree species</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphate%20bonded%20composites" title=" phosphate bonded composites"> phosphate bonded composites</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20properties" title=" physical properties"> physical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/48207/evaluation-of-invasive-tree-species-for-production-of-phosphate-bonded-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48207.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">295</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">3202</span> A Cross-Cultural Approach for Communication with Biological and Non-Biological Intelligences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Schalow">Thomas Schalow</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper posits the need to take a cross-cultural approach to communication with non-human cultures and intelligences in order to meet the following three imminent contingencies: communicating with sentient biological intelligences, communicating with extraterrestrial intelligences, and communicating with artificial super-intelligences. The paper begins with a discussion of how intelligence emerges. It disputes some common assumptions we maintain about consciousness, intention, and language. The paper next explores cross-cultural communication among humans, including non-sapiens species. The next argument made is that we need to become much more serious about communicating with the non-human, intelligent life forms that already exist around us here on Earth. There is an urgent need to broaden our definition of communication and reach out to the other sentient life forms that inhabit our world. The paper next examines the science and philosophy behind CETI (communication with extraterrestrial intelligences) and how it has proven useful, even in the absence of contact with alien life. However, CETI’s assumptions and methodology need to be revised and based on the cross-cultural approach to communication proposed in this paper if we are truly serious about finding and communicating with life beyond Earth. The final theme explored in this paper is communication with non-biological super-intelligences using a cross-cultural communication approach. This will present a serious challenge for humanity, as we have never been truly compelled to converse with other species, and our failure to seriously consider such intercourse has left us largely unprepared to deal with communication in a future that will be mediated and controlled by computer algorithms. Fortunately, our experience dealing with other human cultures can provide us with a framework for this communication. The basic assumptions behind intercultural communication can be applied to the many types of communication envisioned in this paper if we are willing to recognize that we are in fact dealing with other cultures when we interact with other species, alien life, and artificial super-intelligence.

Kariyawasam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The distribution of gorse (Ulex europaeus) plants in South Australia has been modelled using 126 presence-only location data as a function of seven climate parameters. The predicted range of U. europaeus is mainly along the Mount Lofty Ranges in the Adelaide Hills and on Kangaroo Island. Annual precipitation and yearly average aridity index appeared to be the highest contributing variables to the final model formulation. The Jackknife procedure was employed to identify the contribution of different variables to gorse model outputs and response curves were used to predict changes with changing environmental variables. Based on this analysis, it was revealed that the combined effect of one or more variables could make a completely different impact to the original variables on their own to the model prediction. This work also demonstrates the need for a careful approach when selecting environmental variables for projecting correlative models to climatically distinct area. Maxent acts as a robust model when projecting the fitted species distribution model to another area with changing climatic conditions, whereas the generalized linear model, bioclim, and domain models to be less robust in this regard. These findings are important not only for predicting and managing invasive alien gorse in South Australia and Sri Lanka but also in other countries of the invasive range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invasive%20species" title="invasive species">invasive species</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxent" title=" Maxent"> Maxent</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20distribution%20modelling" title=" species distribution modelling"> species distribution modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=Ulex%20europaeus" title=" Ulex europaeus"> Ulex europaeus</a> </p> <a href="https://publications.waset.org/abstracts/97750/invasive-ranges-of-gorse-ulex-europaeus-in-south-australia-and-sri-lanka-using-species-distribution-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97750.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">134</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">3199</span> Microbiological Analysis of Soil from Onu-Ebonyi Contaminated with Inorganic Fertilizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20N.%20Alo">M.

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">3197</span> A Predator-Prey Model with Competitive Interaction amongst the Preys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Titus%20G.%20Kassem">Titus G.

These restoration processes are expensive and have to be evidence-based. In this study in-stream macroinvertebrate and adult Odonata assemblages were used as indicators of restoration success by quantifying the response of biodiversity metrics for these two groups to the removal of IAP’s in a strategic water resource of South Africa that is extensively invaded by invasive alien plants (IAP’s). The study consisted of a replicated design that included 45 sampling units, viz. 15 invaded, 15 uninvaded and 15 cleared sites stratified across the upper reaches of six sub-catchments of the Luvuvhu river catchment, Limpopo Province. Cleared sites were only considered if they received at least two WfW treatments in the last 3 years. The Benthic macroinvertebrate and adult Odonate assemblages in each of these sampling were surveyed from between November and March, 2013/2014 and 2014/2015 respectively. Generalized Linear Models (GLM) with a log link function and Poisson error distribution were done for metrics (invaded, cleared, and uninvaded) whose residuals were not normally distributed or had unequal variance and for abundance. RDA was done for EPTO genera (Ephemeroptera, Plecoptera, Trichoptera and Odonata) and adult Odonata species abundance. GLM was done to for the abundance of Genera and Odonates that had the association with the RDA environmental factors. Sixty four benthic macroinvertebrate families, 57 EPTO genera, and 45 adult Odonata species were recorded across all 45 sampling units. There was no significant difference between the SASS5 total score, ASPT, and family richness of the three invasion classes. Although clearing only had a weak positive effect on the adult Odonate species richness it had a positive impact on DBI scores. These differences were mainly the result of significantly larger DBI scores in the cleared sites as compared to the invaded sites. Results suggest that water quality is positively impacted by repeated clearing pointing to the importance of follow up procedures after initial clearing. Adult Odonate diversity as measured by richness, endemicity, threat and distribution respond positively to all forms of the clearing. The clearing had a significant impact on Odonate assemblage structure but did not affect EPTO structure. Variation partitioning showed that 21.8% of the variation in EPTO assemblage can be explained by spatial and environmental variables, 16% of the variation in Odonate structure was explained by spatial and environmental variables. The response of the diversity metrics to clearing increased in significance at finer taxonomic resolutions, particularly of adult Odonates whose metrics significantly improved with clearing and whose structure responded to both invasion and clearing. The study recommends the use of DBI for surveying river health when hydraulic biotopes are poor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DBI" title="DBI">DBI</a>, <a href="https://publications.waset.org/abstracts/search?q=evidence-based%20conservation" title=" evidence-based conservation"> evidence-based conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=EPTO" title=" EPTO"> EPTO</a>, <a href="https://publications.waset.org/abstracts/search?q=macroinvetebrates" title=" macroinvetebrates"> macroinvetebrates</a> </p> <a href="https://publications.waset.org/abstracts/52779/the-impact-of-riparian-alien-plant-removal-on-aquatic-invertebrate-communities-in-the-upper-reaches-of-luvuvhu-river-catchment-limpopo-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52779.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">186</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">3194</span> Computing the Similarity and the Diversity in the Species Based on Cronobacter Genome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Al%20Daoud">E.

Whose introduction causes or is likely to cause economic, ecological, or environmental harm. The integrated management of the invasive plant, Tithonia diversifolia, will be assessed through two herbicide trials (one on the seedlings and the other on matured plants) and a competitive trial between Tithonia and invasive grass species. The initial herbicide trial will be undertaken at the University of Venda Agricultural greenhouse facilities, where Tithonia will be planted in pot plants and watered every after two days until they reach at least 30 cm and will then be subjected to four different herbicide treatments (Metsulfuron methyl, Fluroxypyr, Picloram, Triclopyr), water will be utilised as a control. The percentage damage to foliar will be recorded. The second herbicide trial will be undertaken at Levubu road site, where matured Tithonia will be cut at at least 10cm above the ground and the subjected to herbicide treatments (Picloram, Fluroxypyr, Imazapyr, and Water as a control). The site will be visited post treatment for assessment. For the competition trial, tall grass species will be chosen as competitors (Panicum maximum and Eragrostis murvula), they will be grown at six densities per pot in the greenhouse facilities at the University of Venda, were they will be kept watered for the duration of the experiment. At the end of the experiment, plants will be removed from pots, and the above and below ground biomass will be weighed. The expected results are to know the effective integrated management strategy for T. diversifolia, the effective rehabilitation of T. diversifolia invaded habitats, and the effective chemical control of T. diversifolia <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foliar" title="foliar">foliar</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=competition" title=" competition"> competition</a>, <a href="https://publications.waset.org/abstracts/search?q=invasion" title=" invasion"> invasion</a> </p> <a href="https://publications.waset.org/abstracts/153732/integrated-management-of-tithonia-diversifolia-in-the-vhembe-biosphere-reserve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153732.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">95</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">3191</span> Palyno-Morphological Characteristics of Gymnosperm Flora of Pakistan and Its Taxonomic Implications with Light Microscope and Scanning Electron Microscopy Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raees%20Khan">Raees Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheikh%20Z.%20Ul%20Abidin"> Sheikh Z.

Pollens of 35 gymnosperm species (12 genera and five families) were collected from its various distributional sites of gymnosperms in Pakistan. LM and SEM were used to investigate different palyno-morphological characteristics. Five pollen types (i.e., Inaperturate, Monolete, Monoporate, Vesiculate-bisaccate, and Polyplicate) were observed. In equatorial view seven types of pollens were observed, in which ten species were sub-angular, nine species were triangular, six species were perprolate, three species were rhomboidal, three species were semi-angular, two species were rectangular and two species were prolate. While five types of pollen were observed in polar view, in which ten species were spheroidal, nine species were angular, eight were interlobate, six species were circular, and two species were elliptic. Eighteen species have rugulate and 17 species has faveolate ornamentation. Eighteen species have verrucate and 17 have gemmate type sculpturing. The data was analysed through cluster analysis. The study showed that these palyno-morphological features have significance value in classification and identification of gymnosperms. Based on these different palyno-morphological features, a taxonomic key was proposed for the accurate and fast identifications of gymnosperms from Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gymnosperms" title="gymnosperms">gymnosperms</a>, <a href="https://publications.waset.org/abstracts/search?q=palynology" title=" palynology"> palynology</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=taxonomy" title=" taxonomy"> taxonomy</a> </p> <a href="https://publications.waset.org/abstracts/82016/palyno-morphological-characteristics-of-gymnosperm-flora-of-pakistan-and-its-taxonomic-implications-with-light-microscope-and-scanning-electron-microscopy-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82016.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">221</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">3190</span> Devising a Paradigm for the Assessment of Guilt across Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trisha%20S.%20Malhotra">Trisha S. Malhotra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While there exist frameworks to study the induction, manifestation, duration and general nature of emotions like shame, guilt, embarrassment and pride in humans, the same cannot be said for other species. This is because such 'complex' emotions have situational inductions and manifestations that supposedly vary due to differences between and within different species' ethology. This paper looks at the socio-adaptive functions of guilt to posit why this emotion might be observed across varying species. Primarily, the experimental paradigm of guilt-assessment in domesticated dogs is critiqued for lack of ethological consideration in its measurement and analysis. It is argued that a paradigm for guilt-assessment should measure the species-specific prosocial approach behavior instead of the immediate feedback of the 'guilty'. Finally, it is asserted that the origin of guilt is subjective and if it must be studied across a plethora of species, its definition must be tailored to fit accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=guilt" title="guilt">guilt</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=dogs" title=" dogs"> dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=prosocial%20approach%20behavior" title=" prosocial approach behavior"> prosocial approach behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=empathy" title=" empathy"> empathy</a>, <a href="https://publications.waset.org/abstracts/search?q=species" title=" species"> species</a>, <a href="https://publications.waset.org/abstracts/search?q=ethology" title=" ethology"> ethology</a> </p> <a href="https://publications.waset.org/abstracts/104123/devising-a-paradigm-for-the-assessment-of-guilt-across-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104123.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">308</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">3189</span> Diversity of Bird Species and Conservation of Two Lacustrine Wetlands of the Upper Benue Basin, Adamawa, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20l.%20David"> D. l.

Two of these invasive plant species, Lantana camara and Chromolaena odorata, are found in the Philippines. Lantana camara has the ability to suppress the growth of and outcompete neighboring plants. Chromolaena odorata causes serious agricultural and economical damage and causes fire hazards during dry season. In addition, both species has been reported to poison livestock. One of the known global management strategies to control invasive plants is the introduction of biological control agents. These natural enemies of the invasive plants reduce population density and impacts of the invasive plants, resulting in the balance of the nature in their invasion. Through secondary data sources, interviews, and field validation (e.g. microhabitat searches, sweep netting, opportunistic sampling, photo-documentation), we investigated whether the biocontrol agents previously released by the Philippine Coconut Authority (PCA) in their Davao Research Center to control these invasive plants are still present and are affecting their respective host weeds. We confirm the presence of the biocontrol agent of L. camara, Uroplata girardi, which was introduced in 1985, and Cecidochares connexa, a biocontrol agent of C. odorata released in 2003. Four other biocontrol agents were found to affect L. camara. Signs of damage (e.g. stem galls in C. odorata, and leaf mines in L. camara) signify that these biocontrol agents have successfully established outside of their release site in Davao. Further investigating the extent of the spread of these biocontrol agents in the Philippines and their damage to the two weeds will contribute to the management of invasive plant species in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invasive%20alien%20species" title="invasive alien species">invasive alien species</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20control%20agent" title=" biological control agent"> biological control agent</a>, <a href="https://publications.waset.org/abstracts/search?q=entomology" title=" entomology"> entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=worst%20weeds" title=" worst weeds"> worst weeds</a> </p> <a href="https://publications.waset.org/abstracts/67203/assessment-of-the-possible-effects-of-biological-control-agents-of-lantana-camara-and-chromolaena-odorata-in-davao-city-mindanao-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67203.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">374</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">3186</span> Species Composition of Alticinae Newman, 1834 (Coleoptera, Chrysomelidae): Distribution and Host Plants in Eastern Upper Plains (Setif, Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Bounechada">M.

Two species of Hesperiidae are reported for Syrian fauna for the first time and one species is newly recorded for Armenia. From the species above mentioned 38 are common both for Syria and Armenia. For estimation of the similarity of faunas studied were used the Jaccard index. By families the index is rather different, consisting for Hesperiidae 0.5151 and for Nymphalidae 0.337. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armenia" title="Armenia">Armenia</a>, <a href="https://publications.waset.org/abstracts/search?q=fauna" title=" fauna"> fauna</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesperiidae" title=" Hesperiidae"> Hesperiidae</a>, <a href="https://publications.waset.org/abstracts/search?q=Nymphalidae" title=" Nymphalidae"> Nymphalidae</a>, <a href="https://publications.waset.org/abstracts/search?q=%28Rhopalocera%3A%20Lepidoptera%29" title=" (Rhopalocera: Lepidoptera)"> (Rhopalocera: Lepidoptera)</a>, <a href="https://publications.waset.org/abstracts/search?q=Syria" title=" Syria"> Syria</a> </p> <a href="https://publications.waset.org/abstracts/48129/a-faunistic-comparative-study-of-families-hesperiidae-and-nymphalidae-lepidoptera-rhopalocera-of-syrian-arab-republic-and-republic-of-armenia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48129.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">252</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">3184</span> Improved Rare Species Identification Using Focal Loss Based Deep Learning Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chad%20Goldsworthy">Chad Goldsworthy</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Rajeswari%20Matam"> B. Rajeswari Matam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of deep learning for species identification in camera trap images has revolutionised our ability to study, conserve and monitor species in a highly efficient and unobtrusive manner, with state-of-the-art models achieving accuracies surpassing the accuracy of manual human classification. The high imbalance of camera trap datasets, however, results in poor accuracies for minority (rare or endangered) species due to their relative insignificance to the overall model accuracy. This paper investigates the use of Focal Loss, in comparison to the traditional Cross Entropy Loss function, to improve the identification of minority species in the “255 Bird Species” dataset from Kaggle. The results show that, although Focal Loss slightly decreased the accuracy of the majority species, it was able to increase the F1-score by 0.06 and improve the identification of the bottom two, five and ten (minority) species by 37.5%, 15.7% and 10.8%, respectively, as well as resulting in an improved overall accuracy of 2.96%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20networks" title="convolutional neural networks">convolutional neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20imbalance" title=" data imbalance"> data imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=focal%20loss" title=" focal loss"> focal loss</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20classification" title=" species classification"> species classification</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20conservation" title=" wildlife conservation"> wildlife conservation</a> </p> <a href="https://publications.waset.org/abstracts/132442/improved-rare-species-identification-using-focal-loss-based-deep-learning-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132442.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">3183</span> Features in the Distribution of Fleas (Siphonaptera) in the Balkhash-Alakol Depression on the South-Eastern Kazakhstan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurtazin%20Sabir">Nurtazin Sabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Begon%20Michael"> Begon Michael</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeszhanov%20Aidyn"> Yeszhanov Aidyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Belyaev"> Alexander Belyaev</a>, <a href="https://publications.waset.org/abstracts/search?q=Hughes%20Nelika"> Hughes Nelika</a>, <a href="https://publications.waset.org/abstracts/search?q=Bethany%20Levick"> Bethany Levick</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmurzauly%20Ruslan"> Salmurzauly Ruslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the features of the distribution of the most abundant species of fleas that are carriers of the most dangerous infections in the Balkhash-Alakol depression of Kazakhstan. We show that of 153 species of fleas described in the territory of the great gerbil (Rhombomys opimus Licht.), 35 species are parasitic. 21 of them are specific to gerbils species, and four species of fleas from the Xenopsylla genus are dominant in number and value of epizootic. We also describe the modern features of habitats of these species and their relationship with the great gerbil populations found in the South Balkhash region. It indicates the need for research on the population structure of the most abundant fleas species and their relationship with the structure of the populations of main carrier of transmission infections in the region-great gerbil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balkhash-Alakol%20depression" title="Balkhash-Alakol depression">Balkhash-Alakol depression</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20foci%20of%20plague" title=" natural foci of plague"> natural foci of plague</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20diversity%20and%20distribution%20of%20fleas" title=" species diversity and distribution of fleas"> species diversity and distribution of fleas</a>, <a href="https://publications.waset.org/abstracts/search?q=flea%20and%20great%20gerbil%20population%20structure" title=" flea and great gerbil population structure"> flea and great gerbil population structure</a>, <a href="https://publications.waset.org/abstracts/search?q=epizootic%20activity" title=" epizootic activity"> epizootic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20species%20of%20fleas" title=" mass species of fleas"> mass species of fleas</a> </p> <a href="https://publications.waset.org/abstracts/27346/features-in-the-distribution-of-fleas-siphonaptera-in-the-balkhash-alakol-depression-on-the-south-eastern-kazakhstan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27346.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">444</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">3182</span> Phylogenetic Relationships between the Whole Sets of Individual Flow Sorted U, M, S and C Chromosomes of Aegilops and Wheat as Revealed by COS Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20Farkas">András Farkas</a>, <a href="https://publications.waset.org/abstracts/search?q=Istv%C3%A1n%20Moln%C3%A1r"> István Molnár</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Vr%C3%A1na"> Jan Vrána</a>, <a href="https://publications.waset.org/abstracts/search?q=Veronika%20Bure%C5%A1ov%C3%A1"> Veronika Burešová</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20C%C3%A1pal"> Petr Cápal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20Cseh"> András Cseh</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rta%20Moln%C3%A1r-L%C3%A1ng"> Márta Molnár-Láng</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Dole%C5%BEel"> Jaroslav Doležel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Species of Aegilops played a central role in the evolution of wheat and are sources of traits related to yield quality and tolerance against biotic and abiotic stresses. These wild genes and alleles are desirable to use in crop improvement programs via introgressive hybridization. However, the success of chromosome mediated gene transfer to wheat are hampered by the pour knowledge on the genome structure of Aegilops relative to wheat and by the low number of cost-effective molecular markers specific for Aegilops chromosomes. The COS markers specific for genes conserved throughout evolution in both sequence and copy number between Triticeae/Aegilops taxa and define orthologous regions, thus enabling the comparison of regions on the chromosomes of related species. The present study compared individual chromosomes of Aegilops umbellulata (UU), Ae. comosa (MM), Ae. speltoides (SS) and Ae. caudata (CC) purified by flourescent labelling with oligonucleotid SSR repeats and biparametric flow cytometry with wheat by identifying orthologous chromosomal regions by COS markers. The linear order of bin-mapped COS markers along the wheat D chromosomes was identified by the use of chromosome-specific sequence data and virtual gene order. Syntenic regions of wheat identifying genome rearrangements differentiating the U, M, S or C genomes from the D genome of wheat were detected. The conserved orthologous set markers assigned to Aegilops chromosomes promise to accelerate gene introgression by facilitating the identification of alien chromatin. The syntenic relationships between the Aegilops species and wheat will facilitate the targeted development of new markers specific for U, M, S and C genomic regions and will contribute to the understanding of molecular processes related to the evolution of Aegilops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aegilops"
