Integrating threat mapping and animal movement data to identify high-risk areas for endangered mobile species

In this study, we introduced a framework for quantifying the exposure to poisoning risk and illustrated an example of an endangered African vulture species, the Lappet-faced Vulture (<i>Torgos tracheliotos</i>). We combined GPS tracking data of 19 individuals collected between 2012 and 2022 with food availability and spatial threat maps of both intentional (poachers directly targeting vultures) and unintentional (farmers aiming to kill carnivores, with vultures being secondarily affected) poisoning across Southern Africa.

本研究提出了一套量化中毒风险暴露水平的研究框架，并以濒危非洲秃鹫物种——皱脸秃鹫（<i>Torgos tracheliotos</i>）为例进行了说明。研究整合了2012年至2022年间收集的19只个体的GPS追踪数据，结合非洲南部地区的食物可获得性数据，以及两类投毒行为的空间威胁分布图：一类为故意投毒（偷猎者直接以秃鹫为目标），另一类为无意投毒（农民为捕杀食肉动物而投毒，秃鹫随之间接受害）。
