摘要

研究了奇米特考拉生境异质性和降雨对小型哺乳动物多样性和繁殖的影响。在6个有代表性的生境中采用网格和线捕获设计收集数据。利用分子技术和R编程软件进行物种鉴定和数据分析。共捕获11种,总捕集成功率为25.6%。最丰富的是水乳螺(Mastomys awashensis),其次是松果(Acomys louisae),最小的是小鳄(Crocidura parvipes)。物种丰富度和多样性以河滨林生境最高,以休耕地生境最低。河流森林丰度最高,草地次之,森林最少。大多数小型兽类的丰度和繁殖活动在雨季明显高于旱季。妊娠偏向于右子宫角而不是左子宫角。小型哺乳动物的多样性和繁殖受到生境生产力的影响,而生境生产力又与季节性降雨有关,反映了生境异质性和季节性资源可得性对物种保护的重要性。

The Influence of Habitat Heterogeneity and Rainfall on Small Mammal Diversity and Reproduction in an Ethiopian Landscape

The influence of habitat heterogeneity and rainfall on small mammal diversity and reproduction was studied in Chimit Kola. Data were collected using a grid and line trapping design in six representative habitats. Species identification and data analysis were performed using molecular techniques and R programming software. A total of 11 species were captured with an overall trap success of 25.6%. Mastomys awashensis was the most abundant, followed by Acomys louisae, and the least was Crocidura parvipes. Species richness and diversity were the highest in the riverine forest and the least in the fallowland habitats. The riverine forest had the highest abundance, followed by grassland and the least was in the forest. The abundance and reproductive activities of most small mammals were significantly higher during the wet season than during the dry season. Pregnancy was biased towards the right uterine horn compared to the left. The diversity and reproduction of small mammals are influenced by habitat productivity, which in turn is associated with seasonal rainfall, reflecting the significance of habitat heterogeneity and seasonal resource availability for the conservation of species.

期刊介绍: African Journal of Ecology (formerly East African Wildlife Journal) publishes original scientific research into the ecology and conservation of the animals and plants of Africa. It has a wide circulation both within and outside Africa and is the foremost research journal on the ecology of the continent. In addition to original articles, the Journal publishes comprehensive reviews on topical subjects and brief communications of preliminary results.
