The utilization of eucalyptus plantations by seven sympatric species of prosimians was studied in the eastern rainforest of Madagascar. The species were Avahi laniger, Cheirogaleus major, Hapalemur griseus, Indri indri, Lemur fulvus, Lepilemur mustelinus, and Microcebus rufus. None of the lemurs was ever found in young eucalyptus plantations with little undergrowth. This was mainly due to the lack of travel opportunities within the shrub layer and between the shrubs and the canopy. Food (mainly berries) is seasonally available in the shrub layer but cannot be exploited because frugivorous lemurs cannot reach it. Old eucalyptus plantations with dense undergrowth are used by all prosimian species. They provide food as well as travel and resting facilities. Mixed tree plantations in the western part of Madagascar were used by groups of Lemur fulvus, Lepilemur mustelinus, and Propithecus verreauxi. According to these results, old eucalyptus plantations and mixed tree species plantations could be used to provide firewood and construction wood for the human population. They also might extend the habitat for lemurs and serve as buffers against human disturbance.
在马达加斯加东部雨林中，研究了七种同域分布的原猴对桉树林的利用情况。这些物种分别是毛耳鼠狐猴、大倭狐猴、灰驯狐猴、大狐猴、褐狐猴、鼬狐猴和红倭狐猴。在林下植被稀少的年轻桉树林中，从未发现过这些狐猴。这主要是因为在灌木层以及灌木与树冠层之间缺乏活动机会。食物（主要是浆果）在灌木层有季节性供应，但由于食果狐猴够不到，无法利用。所有原猴物种都会利用林下植被茂密的老桉树林。它们提供食物以及活动和休息场所。马达加斯加西部的混交林被褐狐猴、鼬狐猴和维氏冕狐猴群体所利用。根据这些结果，老桉树林和混交林可用于为人类提供柴火和建筑木材。它们还可能扩大狐猴的栖息地，并作为抵御人类干扰的缓冲地带。
