Measuring fitness costs of habitat degradation in an endangered primate

covid - 19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抽样。选取10只爪哇懒猴和1只巽他懒猴（Nycticebus coucang）进行激素和寄生虫学分析。四只懒猴在放生前安装了GPS项圈，我们收集了每只懒猴206到408个GPS位置。释放后，有两人分别在35天和90天内死亡。我们继续监测两个人（迄今为止：监测125天）。放生后的迁移和生境选择的初步分析表明，不同个体的空间利用策略不同。有些人在释放后的几周内迅速建立了家园范围，并且探索性运动的频率很低。在90天的监测后，一个个体仍然表现出探索性运动和较低的场地保真度。利用资源选择函数对生境选择进行了研究，发现放生后3个月内死亡的个体倾向于使用受人类干扰较多的区域。低样本量是一个限制因素，更多的个体需要纳入我们的分析，以得出可靠的结论。我们还完成了异国宠物咖啡馆的项目，记录了日本咖啡馆中属于430种不同物种的3799只野生动物的存在。基于本研究的稿件已被《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.
