The mugger () is a medium-sized crocodilian inhabiting South Asia. As a result of intensive hunting, its range declined drastically up till the 1970s. Currently, the world mugger population is fragmented and threatened mainly by habitat loss and the consequences of human-crocodile conflict, being classified as Vulnerable by the IUCN. The goal of this paper is to comprehensively determine the mugger's current range, and assess risks in notable habitats of the species across its range. To determine the range and notable habitats, extensive literature covering surveys, monitoring, population studies and reports of human-crocodile conflict was examined. Habitat suitability and risk assessment were performed by evaluating selected habitats using eight factors: the legal status of the area, elevation, surface water availability, water quality, salinity, availability of nesting and basking sites, interaction with humans and interspecific competition. Based on our findings, the chances of the mugger's survival varies greatly across its range and the threats they face are complex and often site-specific. Defining these threats is the first step for determining suitable risk mitigation efforts, some of which are explored in this review.
泽鳄是一种栖息在南亚的中型鳄鱼。由于过度捕猎,其分布范围在20世纪70年代前急剧缩小。目前,全球泽鳄种群呈碎片化分布,主要受到栖息地丧失以及人类与鳄鱼冲突后果的威胁,被世界自然保护联盟列为易危物种。本文的目的是全面确定泽鳄当前的分布范围,并评估该物种在其分布范围内显著栖息地的风险。为了确定分布范围和显著栖息地,我们查阅了涵盖调查、监测、种群研究以及人类与鳄鱼冲突报告的大量文献。通过使用八个因素对选定栖息地进行评估来开展栖息地适宜性和风险评估:该区域的法律地位、海拔、地表水可利用性、水质、盐度、筑巢和晒太阳地点的可利用性、与人类的互动以及种间竞争。根据我们的研究结果,泽鳄在其分布范围内的生存机会差异很大,它们面临的威胁复杂且往往因地点而异。明确这些威胁是确定合适的风险缓解措施的第一步,本文对此进行了一些探讨。
