马来飞狐猴（Galeopterus variegatus）属于皮翅目，主要分布在泰国南部、印度支那、马来半岛、苏门答腊、爪哇、婆罗洲和附近岛屿（Lim 2007）。它栖息在低地和山区，并在各种各样的栖息地，包括原始林和次生林，椰子格罗夫斯林和橡胶种植园（Lim 2007; Baba 2008）。最近关于飞狐猴线粒体DNA的数据表明，该物种与灵长类动物密切相关，可能与我们的远亲有关（Schmitz et al. 2002; Lim 2007）。摄食、活动范围、社会和繁殖行为数据是动物生态学的基本信息。然而，据我们所知，有关飞狐猴栖息地利用及其决定因素的信息仍然有限，基本上，我们只知道飞狐猴是树栖和夜行动物（Byrnes等人，2011年），在白天，它们可以在树洞或洞穴中找到（Yasuma 1994），挂在树枝上，或抓住树干，他们在黄昏时活跃（Lim 2007）。最近的研究报告了它们的家域大小，夜间活动和栖息地偏好（Baba 2008; Lim et al. 2013）。关于进食行为，与其姐妹菲律宾物种（Wischusen和里士满，1998年）相比，关于马来飞狐猴的信息是零散的（Agoramoorthy等人，2006年; Lim，2007年; Baba，2008年; Dzulhelmi和Abdullah，2009年）。在这项研究中，我们调查了栖息在印度尼西亚西爪哇的野生马来飞狐猴的昼夜休息地点选择，在植物物种和景观水平。我们重点关注森林结构，例如隐蔽区域和树冠覆盖的范围，因为这些通常会影响其他哺乳动物物种的休息地点选择（Heymann 1995; Di Bitetti et al. 2000; Tsuji 2011）。Lim等人（2013）报告称，新加坡的飞狐猴更喜欢覆盖率较高的森林地区;因此，我们的目的是在我们的研究中心证实这一发现。此外，我们还记录了白天吃的几种食物。白天进食的相对重要性似乎低于夜间，但提供很少研究的哺乳动物物种的饮食的基本信息将是有意义的。
The Malayan flying lemur (Galeopterus variegatus) belongs to the Order Dermoptera, and is mainly distributed in the southern parts of Thailand, Indochina, Malay Peninsula, Sumatra, Java, Borneo, and the islands nearby (Lim 2007). It inhabits both lowland and mountainous areas, and is found in a large variety of habitats, including primary and secondary forests, coconut groves, and rubber plantations (Lim 2007; Baba 2008). Recent data on mitochondrial DNA of the flying lemurs have shown that this species is closely related to primates, likely related to our distant relatives (Schmitz et al. 2002; Lim 2007). Feeding, ranging, social, and reproductive behaviour data are fundamental information on animal ecology. However, to the best of our knowledge, information on habitat utilisation by flying lemurs and its determinants remains limited, and basically, we only know that flying lemurs are arboreal and nocturnal animals (Byrnes et al. 2011), that during the daytime they can be found in tree holes or hollows (Yasuma 1994), hanging from branches, or holding onto tree trunks, and that they are active at dusk (Lim 2007). Recent studies have reported about their home range size, nocturnal activity, and habitat preference (Baba 2008; Lim et al. 2013). With regard to feeding behaviour, information about Malayan flying lemur is fragmental (Agoramoorthy et al. 2006; Lim 2007; Baba 2008; Dzulhelmi and Abdullah 2009), compared to its sister Philippine species (Wischusen and Richmond 1998). In this study, we investigated diurnal resting site selection by the wild Malayan flying lemurs inhabiting West Java, Indonesia, at the plant-species and landscape level. We focused on forest structure, such as the extent of concealed areas and canopy cover, as these often influence resting site selection in other mammal species (Heymann 1995; Di Bitetti et al. 2000; Tsuji 2011). Lim et al. (2013) reported that flying lemurs in Singapore preferred forested areas with higher coverage; therefore, we aimed to confirm this finding in our study site. Besides we record several food items eaten in daytime. The relative importance of the daytime feeding seems lower than nocturnal one, but providing fundamental information on diet of the rarely studied-mammalian species would be meaningful.
