Abstract

The study on medium and large-sized mammalian species' diversity and distribution is important for conservation efforts in the different protected areas of Ethiopia. The present study was intended to investigate the species diversity of medium and large-sized mammalian fauna between October 2019 and July 2020 in Michole Community Protected Forest, southern Ethiopia. The study was conducted by stratification of the study area into three habitat types: riverine forest (3.37 km2), woodland (4.14 km2), and grassland with scattered trees (2.33 km2) based on the vegetation cover. A diurnal transect survey method was implemented to record the mammalian species diversity. A total of 18 representative sample transect lines (six in riverine forest, four in grassland with scattered trees, and eight in woodland habitats) that varied in length and width were used. A total of 17 species of medium and large-sized mammalian species were identified and recorded in the study area. As a result, the orders Carnivora and Primates have the greatest abundance, while the order Lagomorpha has the least. Anubis baboon (Papio anubis) was the most abundant species (15.14%), followed by Spotted hyena (Crocuta crocuta) (12.98%), Crested porcupine (Hystrix cristata) (12.51%), Vervet monkey (Chlorocebus aethiops) (10.35%), Common duiker (Sylvicapra grimmia) (8.80%), and Giant root-rat (Tachyoryctes macrocephalus) (8.65%). The distributions of mammals among the three habitat types were comparable. The riverine forest harbored the highest mammalian diversity index (H' = 2.35) followed by the woodland (H' = 2.32), and the grassland with scattered trees (H' = 2.30), respectively. The greatest species similarity was recorded in woodland (0.902). The study area harbors considerable mammalian species that are threatened by interacting anthropogenic factors. So, urgent conservation measures by concerned sectors are needed to safeguard these animals and their habitat.

埃塞俄比亚南部Michole群落保护区陆生大中型哺乳动物物种多样性。
研究埃塞俄比亚不同保护区大中型哺乳动物物种的多样性和分布对保护工作具有重要意义。本研究旨在调查2019年10月至2020年7月埃塞俄比亚南部Michole社区保护区大中型哺乳动物的物种多样性。根据植被覆盖度将研究区划分为3种生境类型:河流森林(3.37 km2)、林地(4.14 km2)和散树草地(2.33 km2)。采用昼夜样带调查方法记录哺乳动物物种多样性。共使用了18条具有代表性的样条线(河流森林样条6条,树木分散的草地样条4条,林地样条8条),它们的长度和宽度各不相同。研究区共鉴定记录到大中型哺乳动物17种。结果表明,食肉目和灵长类目的数量最多,而Lagomorpha目的数量最少。种类最多的是狒狒(Papio Anubis)(15.14%),其次是斑鬣狗(Crocuta Crocuta)(12.98%)、冠豪猪(Hystrix cristata)(12.51%)、黑尾猴(Chlorocebus aethiops)(10.35%)、狐猴(Sylvicapra grimmia)(8.80%)和巨根鼠(Tachyoryctes macrocephalus)(8.65%)。三种生境类型的哺乳动物分布具有可比性。哺乳动物多样性指数最高的是河流森林(H′= 2.35),其次是林地(H′= 2.32)和树木分散的草地(H′= 2.30)。林地物种相似度最高,为0.902。研究区有相当多的哺乳动物物种受到相互作用的人为因素的威胁。因此,需要有关部门采取紧急保护措施,保护这些动物及其栖息地。
