马来亚狐猴是一种夜间活动的哺乳动物，生活在东南亚的森林中。2003年8月至11月进行了调查，首次估计了新加坡动物园内马来亚飞猴的种群密度。研究区域由新加坡动物园和夜间野生动物组成，位于中央流域自然保护区，新加坡现存的大部分天然森林都在这里发现。动物园由28公顷的景观栖息地组成，邻近的夜间野生动物园由40公顷的次生雨林组成。动物园和夜间野生动物园的飞行狐猴密度估计分别为15只和24只。分析了7种首选食物植物和另外10种在这些地点常见但不被飞猴吃掉的植物，以比较矿物和植物化学含量。飞行狐猴摄入的叶子中钾和氮含量明显较少，但单宁含量较高(p<；0.05)。这项研究表明，飞行狐猴能够在改变和支离破碎的地形中生存。保护和管理策略对于保护新加坡日益减少的栖息地至关重要。
The Malayan flying lemur (Cynocephalus variegatus) is a nocturnal mammalian arboreal folivore that inhabits the forests of Southeast Asia. Surveys were conducted from August to November 2003 to estimate the population density of Malayan flying lemurs for the first time in the Singapore Zoological Gardens. The study area consisting of Singapore Zoo and Night Safari was located in the Central Catchment Nature Reserve, where most of Singapore's remaining natural forest is found. The Zoo consisted of 28 ha of landscaped habitat and the adjacent Night Safari consisted of 40 ha of secondary rainforest. The density estimates of flying lemurs in the Zoo and Night Safari were 15 and 24 individuals respectively. Seven plant species that were the preferred food items and an additional 10 plants that were common in the sites but not eaten by the flying lemurs were analysed to compare the mineral and phytochemical contents. Flying lemurs consumed leaves containing significantly less potassium and nitrogen but higher tannin (p < 0.05). The study shows that flying lemurs are able to survive in altered and fragmented landscapes. Conservation and management strategies are essential to protect the shrinking habitats in Singapore.
