The future of wild populations of the red ruffed lemur became much brighter when, in March of 1997, the 840-square-mile Masoala National Park, Madagascar’s largest protected area, was established. Previous to the establishment of this park, deforestation in their range and hunting and trapping of the ruffed lemurs for food had dramatically reduced their numbers.
The red ruffed lemur is one of the largest species of lemur. Red ruffed lemurs’ live on the east coast of Madagascar, in almost overlapping ranges with its sister species the black and white ruffed lemur. Despite living in separate ranges, and being separate species the two can understand each other’s calls and communications.
Many lemurs, such as the Red-ruffed Lemur, and many types of bamboo lemurs are critically endangered. With a drastically reduced home ground there are few left in the natural state. The Hairy-eared Dwarf Lemur, Golden-brown Mouse Lemur, and the Black and White Ruffed Lemurs are non as near to extinction, but are listed as endangered.
The activity budgets and daily activity rhythms of Varecia rubra were examined over an annual cycle according to season and reproductive stage. Given the relatively high reproductive costs and patchy food resources of this species, I predicted that V. rubra would 1) travel less and feed more during seasonal resource scarcity in an attempt to maintain energy balance, and 2) show sex differences.
The rare black-and-white or black-and-red ruffed lemurs (genus Varecia) live in rainforests on the eastern side of Madagascar. The gentle lemurs, or lesser bamboo lemurs (genus Hapalemur), and the highly endangered greater bamboo lemurs (Prolemur simus) feed on bamboo stems in the eastern and northwestern rainforests of the island.
Varecia rubra (red ruffed lemur) currently lives, along with all extant lemurs, on the island-nation of Madagascar. The Antainambalana River dissects the Peninsula area, separating the range of red ruffed lemurs from their close relatives, black-and-white ruffed lemurs (Varecia variegata).
The red-fronted lemur is protected in at least ten Madagascar reserves and is classified as Near Threatened by the International Union for Conservation of Nature (IUCN). Sexual Dichromatism Red-fronted lemurs are sexually dichromatic (different coloration in males vs. females) and the sexes are easily distinguished from each other.
