狐蝠科（Pteropodidae）果蝠是多种新型高致病性病毒的天然宿主，威胁着家畜和人类的健康。我们使用GPS数据记录仪记录了菲律宾金冠狐蝠Acerodon jubatus的夜间觅食活动，以更好地了解这一标志性物种的景观利用，具有预防疾病出现和支持保护管理的双重目标。在54 A中的8个上部署了数据记录器。2010年11月22日至12月2日，在菲律宾吕宋岛苏比奇湾附近捕获了一条幼鲸（2条雄性和6条雌性）。体重范围为730 g至1002 g，相当于体重的3-4%。八个记录器中有六个在2-10天内产生了有用的数据，显示了蝙蝠个体运动的性质和范围的变化。大部分的觅食地点是在封闭的森林，大多数是远离明显的人类活动。46个离散觅食地点和5个以前未记录的栖息地进行了鉴定。我们的研究结果表明，觅食是不是一个随机事件，大多数蝙蝠表现出重复的觅食运动夜间到夜间，显然完整的森林提供了主要的觅食资源，已知的栖息地大大低估了真实的数量（和位置）的栖息地。我们的初步研究结果支持政策和决策的各个方面，包括景观管理，物种保护和潜在的疾病出现。
Species of Old World fruit-bats (family Pteropodidae) have been identified as the natural hosts of a number of novel and highly pathogenic viruses threatening livestock and human health. We used GPS data loggers to record the nocturnal foraging movements of Acerodon jubatus, the Golden-crowned flying fox in the Philippines to better understand the landscape utilisation of this iconic species, with the dual objectives of pre-empting disease emergence and supporting conservation management. Data loggers were deployed on eight of 54 A. jubatus (two males and six females) captured near Subic Bay on the Philippine island of Luzon between 22 November and 2 December 2010. Bodyweight ranged from 730 g to 1002 g, translating to a weight burden of 3–4% of bodyweight. Six of the eight loggers yielded useful data over 2–10 days, showing variability in the nature and range of individual bat movements. The majority of foraging locations were in closed forest and most were remote from evident human activity. Forty-six discrete foraging locations and five previously unrecorded roost locations were identified. Our findings indicate that foraging is not a random event, with the majority of bats exhibiting repetitious foraging movements night-to-night, that apparently intact forest provides the primary foraging resource, and that known roost locations substantially underestimate the true number (and location) of roosts. Our initial findings support policy and decision-making across perspectives including landscape management, species conservation, and potentially disease emergence.
