“…The total number, length and distance and width of line transects were determined by the size and topography of the sites. 2,16 Diversity and threat data of mammals in the study site was collected from the established line transect in each habitat from April 2018 to May 2018. 5 Direct and indirect observations of medium and large mammals were conducted along randomly selected transects (trails, footpaths and other access routes).…”

“…Mammals are an important ecological constituent of terrestrial ecosystems. 1 Large−sized mammals (weigh more than 7kg) and medium−sized mammals (weigh between 2 and 7kg), 2 in particular have important ecosystem functions. 3 They regulate plant diversity and structure and potential pest species through hervibory, other animal populations through predation, and plant dispersion through seeds consumption.…”

“…1,4 Large−sized animals are more vulnerable to local extinction than their small sized counterparts because of their large home-range requirements, naturally low population densities, and are typically favored targets for hunting. 2,4 It is also very difficult to study mammals because most of the species are cryptic, occur at low densities, nocturnal, or inherently difficult to observe. 1 Recently, numerous anthropogenic factors have promoted habitat loss and fragmentation, and the decline and losses of global mammalian biodiversity.…”

Mammal inventories are essential tools to effectively direct conservation strategies and management practices. A survey of large and medium-sized mammals was conducted in Wabe Forest fragments near to Wolkite town of Ethiopia to assess their diversity and abundance in the area and to determine their major threats. Transect method and anecdotal interviews were used to collect data for the study. A total of 12 mammal species belonging to seven orders and seven families were recorded by direct and indirect evidences. Porcupine (Hystrix cristata), honey badger (Mellivera capensis), vervet monkey (Chlorocebus aethiops), olive baboon (Papio anubis), and colobus guereza (Colobus guereza) were among the medium-sized mammals, and spotted hyena (Crocuta crocuta), aardvark (Oryctropus afer), bohor reedbuck (Redunca redunca), Oribi (Ourebia ourebi) and common duiker (Sylvicapra grimmia) were the large mammals of the study area. Vervet monkey (C. aethiops) was the dominant species followed by guereza (Colobus guereza), whereas common duiker (S. grimmia), spotted hyena (C. crocuta) and bush pig (Pontamochoreus larvatus) were less common. Mammals were recorded in low population number in the study area. Simpson's Similarity Index (SI) showed a considerable overlap of species between the natural forest and scrubland habitats (0.58%) with reference to species composition. Field observation and interviews indicated illegal logging of trees for fuel wood and charcoal production, domestic dogs, road construction and extraction of construction materials, and agricultural land expansion were the main anthropogenic threats in the area. The study area harbors considerable mammals that are threatened by interacting anthropogenic factors. Urgent conservation program is needed to safeguard these animals.

“…Higher animals, such as mammals, have been demonstrated to be significantly influenced by human activities, and the destruction of natural habitats is considered to be the major threat to wild animals [8]. According to the IUCN (International Union for Conservation of Nature) Red List [9], 286 species of 5801 mammalian species recorded are listed as EX (extinct) or EW (extinct in the wild).…”

Through history, the habitats of wild mammals have changed greatly in China. Habitat changes may reflect changes in the environment and human–wildlife conflicts. This study focused on how the habitat changed for six taxa of rare wild mammals (one family, one genus, and four species) in mainland China. Their historical and current habitats were estimated according to their historical and current presence occurrences and three sets of environmental data (climate data, topography data, and human activity data), using the Maximum Entropy Model. Then, spatial statistical methods were used to analyze the changes in their habitats, and how human activities have influenced changes in their habitat. The results suggest that the habitats of all six taxa of mammals have shrunk considerably, compared to their historical ranges. With regards to current or past habitats, on average, 68.3% of habitats have been lost. The Asian elephant, which is facing the most serious habitat losses, has lost 93.1% of its habitat. By investigating the relationship between the changes in habitats and the anthropogenic impacts for each taxa, human activities have an obvious negative influence on mammal habitats. The sensitivity of habitats to human activities varies among different mammals: the tiger, Asian elephant, Bactrian camel, and snub-nosed monkey are more sensitive to human activities than musk deer and Chinese water deer.

“…The loss and modification of natural habitats have been considered the greatest threats to the conservation of the diversity and the main disturbing agent of the mammal communities (Cuarón, 2000;Porras et al, 2016). Medium and large sized mammals are key elements to the ecosystem, as they play an important role in forest maintenance and regeneration, as well as providing ecological services that are essential for the environment in ISSN On-Line: 1807-0205 ISSN Printed: 0031-1049 ISNI: 0000-0004-0384-1825 structuring the biological communities (Cuarón, 2000;Jones & Safi, 2011).…”

Medium and large sized mammals of the Boqueirão da Onça, North of Bahia State, Brazil

et al. 2019

The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order to characterize the community of mammals of this region, considering species richness, we installed 80 camera-trap stations. With a sampling effort of 10,370 camera-days we recorded 28 species (22 wild and six domestic). Opportunistically, we recorded four mammals, resulting in a total richness of 32 species, five of which are included in the global list of endangered species, and seven in the national list. The results are significant, since the richness of wild mammals of the Boqueirão da Onça (S = 26) presented a high value when compared to other Caatinga localities. During the study we found evidence of human activities threatening the conservation of the region, such as poaching and deforestation. Therefore, there is an urgent need in the publication of the Management Plan of the recently created Boqueirão da Onça National Park, to minimize negative impacts on biodiversity and ensure the maintenance of ecological processes.
