Supplementary Material for: Initial reintroduction of the aye-aye (Daubentonia madagascariensis) in Anjajavy Reserve, Northwestern Madagascar

Madagascar’s biodiversity is imperiled by habitat loss and degradation. Furthermore, species may be locally extirpated due to targeted hunting or disease. Translocating at-risk individuals to areas devoid of the species may be an effective conservation intervention. The aye-aye, Daubentonia madagascariensis, is uniquely susceptible to hunting pressure due to a cultural superstition. In June 2018, we reintroduced two aye-ayes in the Anjajavy Reserve, a dry deciduous forest in northwestern Madagascar. The translocated individuals, an adult female and juvenile offspring, were rescued from a neighboring forest that was subjected to pressure from fires and logging. We safely secured and transported the aye-ayes to Anjajavy and put them in a quarantine enclosure, where they were subjected to biomedical and behavioral monitoring. After release in the adjacent, protected forest, we conducted post-release monitoring of the adult female using radio-tracking and scan sampling to determine ranging and activity patterns. We conducted behavioral observations from October 2018 to February 2019 and collected sleeping site data from October 2018 to September 2019. The female aye-aye fed on local resources including Canarium sp. seeds. During the study period, the aye-aye used 31 nests, occupied a home range of approximately 85 ha and travelled, on average, at a pace of 320 meters per hour. Our findings are comparable with published data on wild aye-ayes in other regions of Madagascar, and provide support for future reintroductions of adult aye-ayes, and potentially other endemic species to the natural and protected habitats of Anjajavy.

马达加斯加的生物多样性正因栖息地丧失与退化而岌岌可危。此外，针对性狩猎或疾病可能导致当地物种局部灭绝。将受威胁个体转移至无该物种分布的区域，或为一项有效的保护干预手段。
指猴（aye-aye，Daubentonia madagascariensis）因文化迷信而易受狩猎压力影响。2018年6月，我们在马达加斯加西北部的旱落叶林安扎雅维保护区（Anjajavy Reserve）实施了2只指猴的再引入工作。
此次被转移的个体为1只成年雌性及其幼崽，它们从一处遭受火灾与伐木干扰的邻近森林中获救。我们对这两只指猴进行了安全收容与转运，并将其安置于检疫笼舍内，期间开展了生物医学与行为监测。
在邻近的保护森林中完成放归后，我们通过无线电追踪与扫描取样法对这只成年雌性指猴开展放归后监测，以确定其活动范围与活动模式。其中，行为观察工作于2018年10月至2019年2月期间开展，睡眠位点数据则于2018年10月至2019年9月期间收集。
该雌性指猴以包括橄榄属（Canarium sp.）种子在内的本土资源为食。研究期间，该指猴共使用31个巢穴，活动范围约85公顷，平均移动速度为每小时320米。
本研究结果与马达加斯加其他地区野生指猴的已发表数据相符，为后续成年指猴乃至其他特有物种在安扎雅维自然保护栖息地开展再引入工作提供了科学支撑。
