The Brazil slender-pouch rat ( Marmosops paulensis , Syn . : Marmosa incana paulensis ) is a species of marsupial that occurs in southeastern Brazil in the states of Minas Gerais , Rio de Janeiro , São Paulo and Paraná .
description
The animals reach a head trunk length of 11.4 to 15.3 cm (males) or 9.8 to 13.9 cm (females), have a 15 to 21.2 cm (males) or 14.5 to 18, 1 cm (females) long tail and reach a weight of 20 to 70 (males) or 16 to 47 g (females). Similar to the gray slim-pouch rat ( Marmosops incanus ), the fur on the back of young animals is about 10 mm long and soft and shorter in older animals. The back fur is dark gray-brown with a reddish tinge, especially on the sides of the body. The cheeks are cream colored with a reddish tinge. There are dark circles around the eyes, which clearly contrast with the light brown color on the muzzle. The tail, the length of which is about 145% of the length of the head, is dark on the upper side, light on the underside and has a white tip. The peritoneum is cream-colored to whitish with a rosy tinge. The legs are dark, the hind feet are white. Less than 25mm tall, the ears are relatively small. Females do not have a pouch. The number of teats varies from 7 to 13. The karyotype consists of a chromosome set of 2n = 14 chromosomes (FN = 24).
Habitat and way of life
The Brazilian slender-pouch rat occurs in the mountain and cloud forests of the coastal mountains of the Brazilian southeast at altitudes above 800 meters. It is probably nocturnal and more ground dwelling than climbing in shrubs. She never climbs trees. The Brazil slender-pouch rat feeds on fruits, flowers, arthropods, and small vertebrates. It eats beetles, grasshoppers, ants, cockroaches, spiders, harvestmen and snails, as well as the fruits of pepper plants , nightshade plants , black- mouth plants , myrtle plants ( campomanesia and guavas ) and rose plants . Females are territory-forming. The territories inhabited by different females do not overlap. The territories of the males overlap with those of other males as well as those of the females. The territories are between 0.14 and 1.5 hectares in size. The breeding season begins in September at the end of the dry season and lasts until March. 7 to 13 young animals are born per litter. Each female has young only once in a lifetime and they die from March to April after the young are weaned. The adult males die in December or January.
status
The Brazil slim-pouch rat has only a relatively small distribution area, but is not considered endangered because it is assumed that the population is relatively large.
