![]() ![]() However, we identified food resources availability, understory structure, predation, and tree hole availability to be the most frequently invoked factors potentially influencing DF use. We found no variation in degraded habitat use, with respect to forest type, conservation status and distribution range. Our results however confirm that most mouse lemur species are able to cope with, but do not necessarily respond positively to habitat degradation. However, data are scarce for most species, and lacking for almost half of the currently recognized species. ![]() We show that data on degraded forest (DF) use is available for 14 species and geographically aggregated in a few locations. We further question whether mouse lemurs show variation in degraded habitat use, with respect to forest type, conservation status and distribution range. Here, we review the literature on mouse lemur use of degraded habitat. However, there are 24 recognized mouse lemur species living in very different habitats, and it is not clear whether all these species respond similarly to forest degradation. Several mouse lemurs (genus Microcebus) have been shown to cope with habitat disturbances and degradation. This biodiversity is threatened by deforestation, forest degradation and anthropogenic disturbances. madagascariensis pourrait etre important pour la conservation des lemuriens dependant de sites dortoirs.read more read lessĪbstract: Madagascar is known for its unique biodiversity including its endemic primates, the lemurs. Cette espece d’arbre concernait 32,5% (n = 150) des 458 sites dortoirs enregistres. Au cours d’une etude realisee dans le Nord de Madagascar, nous avons observe que Strychnos madagascariensis (Loganiaceae) etait frequemment utilise comme site dortoir par les deux especes de lepilemurs presentes, Lepilemur ankaranensis and L. L’identification des especes d’arbres indigenes creuses de trous et utilises par les lemuriens pourrait faciliter la mise en place d’actions de conservation ayant pour but de maintenir ou ameliorer l’habitat de ces lemuriens. Dans ce contexte, une disponibilite reduite d’arbres pourvus de cavites pourrait entrainer le declin des especes dependant de ces abris comme par exemple les lepilemurs, un des groupes de lemuriens les plus riches en especes. ![]() A Madagascar, les taux de deforestation historiques et actuels sont responsables d’une crise environnementale majeure. Resume De nombreux vertebres forestiers a travers le monde trouvent refuge dans des cavites et des trous d’arbres. madagascariensis may be valuable for the conservation of hollow-dwelling lemurs. This tree species represented 32.5% (n=150) of the 458 sleeping sites recorded. During an extensive survey of sportive lemurs in northern Madagascar, we identified one tree species, Strychnos madagascariensis (Loganiaceae), the spineless monkey orange tree, as a principal sleeping site of two species of northern sportive lemurs, Lepilemur ankaranensis and L. The identification of native tree species used by hollow-dwelling lemurs may facilitate targeted management interventions to maintain or improve habitat quality for these lemurs. In Madagascar, where high historical and ongoing rates of deforestation and forest degradation are responsible for a major environmental crisis, reduced availability of tree hollows may lead to declines in hollow-dwelling species such as sportive lemurs, one of the most species-rich groups of lemurs. Abstract: Tree hollows provide shelters for a large number of forest-dependent vertebrate species worldwide. ![]()
