Measuring fitness costs of habitat degradation in an endangered primate

COVID19阻止了这名男子前往印度尼西亚，因此我们在YIARI救援中心的同事进行了采样。在可能的情况下，对10只爪哇懒猴和1只舜达懒猴进行激素和寄生虫学分析。在放生前，四只懒猴被安装了GPS项圈，我们收集了每个个体206到408个GPS位置。自他们获释以来，有两人在35天和90天内死亡。我们继续监测两个个体(到目前为止：125天的监测)。对释放后的活动和栖息地选择的初步分析表明，空间利用策略在个体之间有所不同。一些个体在释放后的几周内迅速建立起家庭活动范围，并且探索性活动的比率很低。一名患者在90天的监测后仍表现出探索性活动和低保真度。利用资源选择功能，我们调查了栖息地选择，发现在放生后3个月内死亡的个体倾向于使用更受人类干扰的地区。低样本量是一个限制因素，我们的分析需要包括更多的个体才能得出可靠的结论。我们还完成了关于外来宠物咖啡馆的项目，并记录了日本机构中存在的属于430个不同物种的3799只野生动物。基于这项研究的手稿已被《保护科学与实践》杂志接受。这项工作显示了这些企业对生物多样性、全球健康和动物福利的潜在影响。

COVID19 prevented the fellow from traveling to Indonesia, so sampling was performed by our colleagues at the YIARI Rescue center. Ten Javan slow lorises and 1 Sunda slow loris (Nycticebus coucang) were sampled, when possible, for hormonal and parasitological analysis. Four lorises were fitted with GPS collars before release, and we collected between 206 to 408 GPS locations per individual. Since their release, two individuals died within 35 and 90 days. We continue to monitor two individuals (to date: 125 days of monitoring).Preliminary analysis of post-release movement and habitat selection show that space-use strategies differ among individuals. Some individuals establish home ranges quickly within a few weeks post release and have a low rate of exploratory movements. One individual still displayed exploratory movements and low site fidelity after 90 days of monitoring. Using resource selection functions, we investigated habitat selection and found that individuals that died within 3 months post-release tended to use areas more disturbed by humans. Low sample size is a limiting factor, and more individuals need to be included in our analysis to draw robust conclusions.We also completed the project on exotic pet cafes and recorded the presence 3799 wild animals belonging to 430 different species in Japanese establishments. The manuscript based on this research has been accepted in the journal "Conservation Science and Practice". This work shows the potential implications for biodiversity, global health and animal welfare of these businesses.
