Abstract

Background: Dumpsites play key role in conservation of birds. A study was conducted to assess the diversity and abundance of birds in dumpsites of Afar region, Ethiopia from August, 2019 to March, 2020, covering both the wet and dry seasons. A total of nine dumpsites that contain domestic wastes found in different towns of Afar region were selected. Point count technique was employed to identify and count the birds. Shannon-Weiner diversity index was used to estimate species diversity and Two-way ANOVA was used to test birds' species richness and abundance variation across dumpsites and seasons.

Results: A total of 48 bird species consisting of one endemic and 10 globally threatened species were recorded. Red-billed Quelea, Marabou Stork and Egyptian Vulture were the most abundant species. There was a significant difference in bird species richness and abundance among dumpsites (F = 8.44, df = 8, P < 0.05) and F = 15.507, df = 8, P < 0.05), respectively. Moreover, a significant difference in abundance was also observed between the two seasons (F = 19.339, df = 1, P < 0.05). The highest species diversity (H' = 3.18) was observed during wet season in Abala and Afambo dumpsites and the highest species evenness (E = 0.86) was observed during dry season in Afdera.

Conclusion: Bird species diversity and abundance among dumpsites was high, and man-made disturbance are main threats for conservation of birds in the area. Therefore, conservation measures are needed to maintain survival of birds mainly the globally threatened species. Moreover, proper management of dumpsites is vital to support the waste dependent birds.

埃塞俄比亚阿法尔地区垃圾场鸟类多样性和丰度:对保护的启示。

背景:垃圾场在保护鸟类方面发挥着重要作用。2019年8月至2020年3月，对埃塞俄比亚阿法尔地区垃圾场鸟类的多样性和丰度进行了一项研究，涵盖了旱季和雨季。在阿法尔地区不同城镇发现的9个生活垃圾垃圾场被选中。采用点计数技术对鸟类进行识别和计数。采用Shannon-Weiner多样性指数估算鸟类物种多样性，采用双因素方差分析(Two-way ANOVA)分析鸟类物种丰富度及其在不同垃圾场和季节间的变化。结果:共记录到鸟类48种，其中特有种1种，全球濒危物种10种。红嘴鸟、马拉布鹳和埃及秃鹫是数量最多的物种。各垃圾场鸟类物种丰富度和丰度差异有统计学意义(F = 8.44, df = 8, P)。结论:垃圾场鸟类物种多样性和丰度较高，人为干扰是影响该地区鸟类保护的主要因素。因此，需要采取保护措施来维持鸟类的生存，主要是全球濒危物种。此外，妥善管理垃圾场对支持依赖废物的鸟类至关重要。

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.
