摘要

摘要在世界范围内，许多草原生境已经消失或发生了重大变化，许多草原特有动物种群面临灭绝的危险。Kori Bustard Ardeotis Kori是非洲本土最大的飞禽，也是开放稀树草原的专家，但在过去的30年里，没有关于纳米比亚Kori Bustard种群生态学的研究发表。利用驱动样带的距离采样，我们估计在2021-2022日历年有0.34±0.1只鸟km - 2，这意味着在576 km2的研究区域内，Kori鸨的种群数量<200(~ 196)只。我们发现，从2016年到2021年，不同季节的密度估计值没有显著变化。在纳米比亚和其他缺乏数据的国家，开展全国范围内的现状调查和潜在限制因素的调查，包括存活率和种群之间的连通性分析，将是更好地为这一濒危物种的保护战略提供信息的重要工作。Statut et densiteise de i 'outarde kori Ardeotis kori, espce menacacei, dans and savane arboracei, ungrande partie des habitats de prairie du monde entier, desdesdessubements, desdeschanges substantiels, desquede nombreuses esp，动物适应sames aux prairies和种群menacei灭绝。我想我是说，我是说我是非洲人，我是说我是非洲人，我是说我是非洲人。在纳米比亚，关于人口和人口的 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -人口基数<200(~ 196)，人口基数<200(~ 196)，人口基数<200(~ 196)，人口基数<200(~ 196)，人口基数<200(~ 196)，人口基数> 576 km2。Nous n 'avons pas trouvous de variation significance dans(2016-2021年)。1 . enquête全国范围内关于电子数据交换和电子数据交换潜力因素限制的分析，包括关于人口的生存和联系的分析、关于企业的重要信息的分析、关于电子数据交换和保护的分析、关于纳米比亚的电子数据交换和关于电子数据交换和危险的分析、关于电子数据交换和电子数据交换的研究、关于电子数据交换和电子数据交换的研究、关于电子数据交换和电子数据交换的研究、关于电子数据交换和电子数据交换的研究、关于电子数据交换和电子数据交换où关于电子数据交换和电子数据交换的研究。关键词:密度估计距离采样草原纳米比亚蜈蚣种群大小样带数据

Status and density of the threatened Kori Bustard Ardeotis kori in a woodland savanna

Many grassland habitats have disappeared or undergone substantial change worldwide and many obligatory grassland animal species have populations that are at risk of extinction. The Kori Bustard Ardeotis kori is the largest flying bird native to Africa and an open savanna specialist, but no research on the population ecology of the Kori Bustard in Namibia has been published in the last 30 years. Using distance sampling from driven transects, we estimated 0.34 ± 0.1 birds km−2 in the 2021–2022 calendar year, which projects a population of <200 (∼196) Kori Bustards for the 576 km2 study area. We found no significant variation in density estimates among seasons from 2016 to 2021. A nationwide status survey and investigation of potential limiting factors, including analysis of survival rates and connectivity between populations, will be important undertakings to better inform conservation strategies for this imperilled species in Namibia and in other range countries with data deficiency.

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.
