The brown maki ( Eulemur fulvus ) is a species of primate from the family of common makis (Lemuridae) within the lemurs (Lemuriformes). The Sanford-Maki , the Red Maki , the red-fronted lemur , the white-headed lemur , the gray-headed lemur and the collared brown lemur , which formerly all as his sub-species have been classified, are now considered separate species.
features
In contrast to most of the other species of the Great Makis , the sexes of the Brown Makis are almost equally colored. The fur is uniformly gray or gray-brown on the upper side, the underside is gray and lighter. The face, the elongated snout and the top of the head are black, but somewhat lighter in the females. The eyebrows and the tufts around the ears are a little lighter in color, the eyes are orange-red. These animals reach a head body length of 43 to 50 centimeters, the long, bushy tail measures 42 to 51 centimeters. The weight of these animals is 2 to 3 kilograms.
distribution and habitat
Brown Makis live in the northern and eastern regions of Madagascar , an introduced population lives next to the island of Mayotte . In Madagascar, its range is now divided into three large parts: a population in the east, which occurs predominantly in rainforests , one in the northwest north of the Betsiboka River and one in the north in the Sambirano region. In the west and north, dry deciduous forests are their habitat. Small populations in forest fragments between the large habitats suggest that their range was earlier contiguous.
Way of life
These primates are tree dwellers who barely get to the ground. They are cathemeral , which means they can be active both day and night. The degree of their nocturnal activity depends on the position of the moon, on moonlit nights they are more active. They live in groups of 3 to 12 (on average 8 to 9) animals, the groups are composed of several adult males and females as well as the young animals. The groups are larger on Mayotte; a group of 29 animals has been observed here. There is no recognizable ranking within a group. The size of the districts depends heavily on the habitat and varies from 7 to 20 hectares.
Their diet consists of leaves, buds, flowers and fruits, and sometimes insects. The composition of the food varies and depends on the habitat and the season.
Mating takes place in May or June, after a gestation period of around 120 days, the female usually gives birth to a single young in September or October, sometimes twins. The young are weaned after four to five months and sexually mature at around one and a half years.
threat
One of the main dangers of the brown makis is the destruction of their habitat through slash and burn and deforestation as well as hunting. The IUCN estimates that the total population has declined by 20 to 25 percent in the last 24 years (three generations) and lists the species as " near threatened ".
In Germany the species is kept in zoos in Nuremberg and Wolgast.
