The golden-brown mouse lemur (Microcebus ravelobensis), also known as the (Lac) Ravelobe mouse lemur, is part of the Cheirogaleidae family, and the smallest species of lemur. It is arboreal, nocturnal and usually social. It get its name from the color of its body. Like several other mouse lemurs, like the brown mouse lemur (Microcebus rufus), it is a small primate that has a brown dorsal side and a whitish-grey for its ventral side of the body. All lemurs live in Madagascar. This species was discovered in 1994. Geographic range and habitat The island of Madagascar is located off the southeastern coast of Africa. All species of lemur are indigenous to the island. The Golden-brown mouse lemur is isolated in the forest reserve of Ankarafantsika National Park, a dry deciduous forest located in northwestern Madagascar. It shares the habitat with the gray mouse lemur,(M. murinus), a sympatric species. Within the habitat that which both the golden-brown lemur and gray mouse lemur live, they occupy two very different niches showing divergent regional distribution and different population density patterns. The golden-brown mouse lemur prefers habitat areas in lower latitudes that are humid and in close proximity to water resources. Whereas the gray mouse lemur populations increase with altitude and are located in drier habitats away from water sources. M. ravelobensis, as well as other species of mouse lemur have been classified as leaf or nest builders. The golden-brown mouse lemur’s habitat is well dispersed among sexes and family groups, showing little sign of intra- or interspecific competition among overlapping territories. In a 2009 study by S. Thoren et al. showed only lactating females were seen building nests, but studies suggest non-lactating females will also. Nest building will take place in the early hours of the night and will take approximately 60 minutes to build. The nests are constructed of small branches and leaves from surrounding vegetation. They will be occupied by lactating or dominant females, their offspring and mixed lineage group members for a period of 36 days. Feeding The golden-brown mouse lemurs are nocturnal creatures, which means they sleep during the day and search for food at night. According to National Geographic, golden-brown mouse lemurs consume “insects, fruit, flowers, and other plants.” They are known to be mostly frugivorous primates (primarily fruit-eating), but they can be omnivorous as well. The brown mouse lemur is able to store “thirty-five percent of their body
