摘要

马来西亚半岛的快速发展和森林砍伐导致热带森林退化和支离破碎,影响了许多巨型动物物种的生存。随着漫游空间的减少,亚洲象(Elephas maximus)可能会将其活动范围扩大到被改变的地貌中,从而导致人象冲突(HEC)。人象冲突是指野象与人类之间的任何互动,这种互动会对人类和大象造成负面影响。虽然大象是该地区的重要物种,但以前从未对冲突和非冲突大象进行过空间比较研究。在这项研究中,我们使用了 2012 年至 2021 年期间五头冲突大象和七头非冲突大象的 GPS 卫星项圈数据。我们绘制了它们的家园范围图,确定了热点地区,并估算了马来西亚半岛大象管理区的栖息地使用比例(面积和时间)。我们发现,12头大象中的9头无论是否处于冲突状态,都有90%的时间在家园范围内度过,95%的时间在森林地区的热点区域度过。然而,冲突状态的大象平均每天移动的距离要比非冲突状态的大象远得多。我们的研究结果凸显了根据威胁程度和栖息地使用情况重新定义大象冲突状态的重要性,以考虑迅速退化的栖息地,这也是人象共存的信号。

Asian elephants involved in conflicts exhibit similar habitat use but travel farther than non-conflict individuals
Rapid development and deforestation in Peninsular Malaysia have degraded and fragmented the tropical forest, impacting the survival of many megafauna species. With reduced space to roam, Asian elephants (Elephas maximus) may extend their range into the altered landscape, leading to human–elephant conflict (HEC). HEC is defined as any interactions between wild elephants and humans that result in negative effects on both humans and elephants. Although known as a keystone species in the region, spatial studies comparing conflict and non-conflict elephants have never been done before. In this study, we used GPS satellite collar data for five conflict and seven non-conflict elephants from 2012 to 2021. We mapped their home ranges, identified hotspots, and estimated the proportion of habitat use (area and time spent) across the Managed Elephant Ranges of Peninsular Malaysia. We found that nine of the 12 elephants spent >90 % of their time in their home range and >95 % of their time in hotspots in forested areas regardless of conflict status. redefining of conflict status as spending <53 % of the time in the home range and <41 % in hotspots in forested areas. However, conflict elephants moved significantly farther on the daily average than non-conflict elephants. Our findings highlight the importance of redefining the conflict status of elephants based on threat levels and habitat use to consider the rapidly degrading habitat that signals human–elephant coexistence.
