El Parque Nacional Bukit Barisan Selatan (BBSNP en sus siglas en ingles) es una de las mayores zonas de conservacion de la isla de Sumatra y es importante para la conservacion de muchas especies amenazadas. El tigre de Sumatra (Panthera tigris sumatrae) se encuentra en peligro critico de extincion y sirve de especie paraguas para la conservacion, pero tambien puede afectar a la actividad y la distribucion de otros carnivoros. Utilizamos camaras de trampeo durante 8 anos en una zona del Parque Nacional BBSNP con escasa actividad humana, a fin de documentar la comunidad local de mamiferos terrestres y estudiar el solapamiento espacial y temporal del tigre con otras especies de carnivoros. Detectamos 39 especies de mamiferos como el tigre de Sumatra y otros varios mamiferos amenazados. La riqueza anual de especies se situo de media en 21,5 mamiferos (intervalo 19–24) y se mantuvo estable a lo largo del tiempo. A diferencia de la situacion de conservacion de la especie, el orden de los mamiferos tuvo un efecto significativo en la deteccion anual de especies y el numero de camaras en las que se detecto una especie. El tigre mostro una pauta de actividad diurna y el mayor solapamiento temporal con el gato jaspeado (Pardofelis marmorata), el cuon (Cuon alpinus) y el oso malayo (Helarctos malayanus), pero poco solapamiento con otros carnivoros. Estos resultados sugieren que algunos carnivoros de menor talla podrian estar ajustando la actividad temporal para evitar a los tigres o a mesocarnivoros. La tendencia estable de la riqueza de especies de mamiferos terrestres pone de manifiesto que el BBSNP sigue siendo una zona importante para la conservacion de la biodiversidad.

Bukit Barisan SelatanNational Park (BBSNP) is one of the largest conserved areas on the island of Sumatra, and is important for the conservation of many threatened species.

Most of the studies were performed by researchers from developed countries. Translocations occurred mostly in temperate regions, with almost no translocations occurring in the tropics. Almost 60 % of the studies did not provide information regarding the success or failure of the translocation programs. The most commonly used technique was hard release. Wild–caught specimens were preferred for translocations. Translocation programs were less common for groups like amphibians, fishes, and invertebrates. If criteria for suitable translocation are met, this management tool should also be conducted for tropical threatened species, led by native researchers. Furthermore, criteria for successful translocation should be clearly identified in order to improve future conservation actions.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2020-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70170399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the fauna of these riparian forests and associated ecosystems can be strongly affected, as is the case with amphibians. In this study we identify how anuran species composition varies in riparian forests with various levels of environmental integrity. The study took place in the Fritz Plaumann State Park (FPSP), a protected area with forest formations typical of the Southern Atlantic Forest. Our results suggest that the environmental integrity of the sampling sites influenced where each species was found. The most preserved habitats, with large areas of riparian forest and fewer anthropic impacts, promoted greater species diversity and allowed for the maintenance of species with specific environmental requirements. Two species registered are on the list of endangered amphibians (Boana curupi and Vitreorana uranoscopa) and one is an exotic invasive species (Lithobates catesbeianus). Because it preys on native amphibians and may act as a pathogen vector, this species is a potential threat to the native amphibian populations inside the park. Even though large portions of the FPSP consist of forests in a secondary stage of succession, the connection with better–preserved areas of primary forest allows for the general occurrence of more demanding species that are usually associated with well–preserved habitats. On a regional level, these habitats occur only inside the park and in their absence, these species will most likely become locally or regionally extinct.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2020-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44437091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we describe the diet of Scinax fuscomarginatus by evaluating its possibly generalist diet related to prey availability in its environment. We studied the diet of Scinax fuscomarginatus by analysing the stomach contents of 48 individuals captured in the Campo Grande municipality, Mato Grosso do Sul state, Brazil. We found eight prey categories, the most common and most representative being Hemiptera. The selectivity index of the two most important prey varied inversely between dry and wet seasons.

Given this species’ economic and ecological importance, priority must be given to management measures aimed at limiting the effects of this disease. However, despite the wealth of research on sarcoptic mange in ibex, no common patterns of action are yet available to manage this disease under field conditions. The lack of national and international protocols aimed at controlling sarcoptic mange has favoured the spontaneous emergence of various disease management initiatives in Spain. However, very little information is available concerning this trend and what there is tends to be available only as ‘grey literature’ or is consigned to the memory of local observers. Traditional strategies designed to combat this disease include the administration of medicated feed and the non–selective culling of mangy ibex. Here, we propose a management approach that takes into account aspects relating to the ecology and conservation of ibex populations, as well as public–health–related factors. Our recommendations are based on knowledge of the disease and host–parasite interaction, and aim to promote long–term advances in its control. Moreover, we discuss the efficacy of the measures traditionally used in mange management. The overall aim is to encourage debate between wildlife managers and motivate the development of alternative management strategies.","PeriodicalId":49107,"journal":{"name":"Animal Biodiversity and Conservation","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2020-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43794128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
