Abstract

Agroforestry is an integrated land-use system that plays a great role in the conservation of landscape biodiversity. The study aimed to assess the composition and diversity of avian species along with different habitat types of agroforestry in Kibet Town, Southern Ethiopia. Four habitat types of agroforestry system which are home gardens, live fences, parkland, and eucalyptus woodlot were identified. Line transects were used for bird surveys. The Shannon diversity index (H′) and species evenness index (E) were used to compare diversity among habitat types. A similarity percentages (SIMPER) test was carried out to identify the main species and feeding guild that typified each habitat type. The overall significance was assessed with the ANOSIM test using PAST (version 4.03). A total of 50 bird species belonging to 28 families and 10 orders were recorded. Order Passeriformes (67.3%) had the highest number of species. Bird community composition differed among habitat types. The dissimilarity was mainly due to White-browed robin-chat (Cossypha heuglini), Streaky seed-eater (Serinus striolatus), Village Weaver (Ploceus cucullatus), African Paradise-Flycatcher (Terpsiphone viridis), and Black-Headed Paradise Flycatcher (T. rufiventer). The finding also revealed that insectivore was the dominant feeding guild. The present study shows evidence that more insectivore bird species use different types of agroforestry as habitat and foraging sites. So, any concerned bodies who have engaged in avian conservation should give special consideration to this modified landscape.

埃塞俄比亚南部Kibet镇不同类型农林业系统鸟类组成及多样性变化研究

农林复合利用是一种综合性的土地利用系统，在保护景观生物多样性方面发挥着重要作用。本研究旨在评估埃塞俄比亚南部Kibet镇农林业鸟类的组成和多样性以及不同生境类型。农林复合系统的生境类型为家庭花园、活动围栏、公园绿地和桉树林地。线样条用于鸟类调查。采用Shannon多样性指数(H’)和物种均匀度指数(E)比较不同生境类型间的多样性。采用相似百分率(SIMPER)检验，确定各生境类型的主要种类和取食区。采用PAST(4.03版)的ANOSIM检验评估总体显著性。共记录鸟类50种，隶属于10目28科。雀形目种类最多，占67.3%。不同生境类型的鸟类群落组成存在差异。差异主要是由于白眉知更鸟(Cossypha heuglini)、条纹食种鸟(Serinus striolatus)、乡村织女(Ploceus cucullatus)、非洲天堂捕蝇鸟(Terpsiphone viridis)和黑头天堂捕蝇鸟(T. rufiventer)。这一发现还表明，食虫动物是主要的摄食群体。目前的研究表明，越来越多的食虫鸟类利用不同类型的农林业作为栖息地和觅食地。因此，任何从事鸟类保育的有关团体都应特别考虑这种经改良的景观。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
