摘要

摘要：估计家园范围大小是生态学研究的一个重要方面，有助于了解物种生物学。食肉树懒（Melursus ursinus）是研究最少的大型食肉动物之一，分布于印度次大陆，印度是其大本营。尽管它在印度分布广泛，但只有一项研究估计了它的家园范围。在这项研究中，我们利用 2019 年和 2020 年期间在印度南部班纳加塔国家公园（Bannerghatta National Park）通过相机追踪获得的位置数据，估算了懒熊的家园范围。根据懒熊皮毛上可能由铁丝网捕获造成的独特标记，确定了懒熊的身份。利用最小凸多边形和 40 次相机诱捕，我们估计其家园范围为 ∼58 平方公里。尽管进行相机诱捕是为了了解豹子的种群动态，但这些数据也提供了非目标物种的机会性信息。应利用这些副产品数据来增强我们对物种生物学各个方面的了解。

Home range estimate of sloth bear using noninvasive camera-trap data

Abstract: Estimating home range size is an important aspect of ecological studies that helps in understanding species biology. The myrmecophagous sloth bear (Melursus ursinus) is one of the least studied large carnivores and is found in the Indian subcontinent with India being its stronghold. Despite its wide distribution in India, only one study has estimated its home range. In this study, we estimate the home range of a sloth bear using location data obtained through camera-trapping in Bannerghatta National Park in southern India during 2019 and 2020. A sloth bear was identified based on a unique marking on its pelage that was possibly caused by a wire snare. Using the minimum convex polygon and 40 camera-trap encounters, we estimated its home range to be ∼58 km2. Although camera-trapping was conducted to understand the population dynamics of leopards (Panthera pardus pardus), the data provided opportunistic information on nontarget species. Such byproduct data should be utilized to enhance our knowledge on various aspects of species biology.
