Microcebus murinus live specifically within Madagascar, a large island about 250 miles from the African mainland (The Africa Guide 2014). Microcebus murinus are one of many arboreal primate species. Microcebus murinus are highly adapted to the arboreal lifestyle. TreesMouse Lemur are adequate sources of protection from predators and extreme temperatures. Microcebus murinus inhabit a variety of habitat types including tropical, scrub, and deciduous forests (Lahann 2008). Although Microcebus murinus spend much of their life in the high tree branches, they come closer to ground level to search for food. To move to different trees, Microcebus murinus leap from the limbs of one tree to the limbs of another tree. You can read more about adaptations to climate in form and function (Animal Diversity Web 2014).
 Mouse Lemur
Microcebus murinus nest in tree holes. This species is selective about their nest sites because small mammals in the forests of Madagascar are under high predation. Microcebus murinus utilize tree holes for adequate protection by keeping themselves hidden. This is a contrast from related lemurs (such as Microcebus ravelobensis) that use less protective shelters and rely on their ability to flee in order to avoid predation. Another factor that affects which tree hole the Microcebus murinus chooses is thermoregulation (Radespiel, et al. 2003).
Microcebus murinus have adapted to share nests under specific circumstances. There Mouse Lemurare also intraspecific differences by sex when it comes to nesting choices. Males tend to sleep alone in their nests and most females sleep in groups. Occasionally, females can even be found nesting with the females of related species. Males also tend to frequently change their nesting site, while females will often return to the same nesting site (Radespiel, et al. 2003).
