Старост
Ground cuscuses have a typical lifespan of 5 to 10 years, with a maximum recorded lifespan of 18 years and 11 months; the theoretical lifespan ranges from 9 years and 6 months to 18 years and 11 months. The species reaches sexual maturity from 7 months and 2 weeks to 1 year of age. The embryo develops in the mother’s uterus for a very short time, after which the young enters the ‘infant’ stage, living in the mother’s pouch, feeding on her milk, and growing for 5 to 7 months. Following this, the animal enters the ‘adult’ stage, lasting from 1 year to 8 years and 3 months, during which it independently forages for food and participates in reproduction.
Фенотип
The ground cuscus has thick fur that protects it from the cold and helps it to camouflage on the forest floor. The species possesses large eyes, which allow for good vision at night. A prehensile tail assists with balance when moving along the ground and low branches. Adult ground cuscuses have a tail that aids in maintaining equilibrium.
Физиологија
The ground cuscus has a body length ranging from 38 to 55 centimeters; its mass varies from 1.89 to 3 kilograms. The embryonic stage exhibits a body mass of 0.2 to 0.5 grams and a body length of 5 millimeters to 1.5 centimeters. During the juvenile stage, the young have a body mass ranging from 5 to 400 grams and a body length from 3 to 15 centimeters. Adult ground cuscuses weigh from 2.2 to 5 kilograms and measure 43 to 55 centimeters in body length.
Станиште
The ground cuscus inhabits tropical moist forests, always hot and humid, characterized by massive trees and vines, and found on land and in forest landscapes; the species’ elevation range extends to 2.8 kilometers above sea level; the climate is consistently hot and wet, with frequent rains and very high humidity year-round, although periods of dryness can occasionally occur; the species experiences very hot conditions throughout the year, with frequent rains, but sometimes dry spells are observed; the habitat is always very wet, with rain occurring almost constantly and extremely high humidity.
Склониште
Ground cuscuses are found on the ground among dense vegetation or beneath fallen trees; the species constructs or utilizes nest structures for laying eggs and raising young. These nests are built from twigs and moss, serving purposes of reproduction, rest, and protection from the sun.
Географија
Ground cuscuses inhabit several biogeographical realms, including Australasia, Afrotropics, Indomalaya, Oceania, and the Palearctic. The species is found in lowland forests of central Congo and forests of the Eastern arc.
Храна
The ground cuscus is an omnivorous species; it consumes fruits, young leaves, insects, and occasionally small vertebrates. The species forages and grazes, searching for and obtaining food through paw manipulation on the ground and in grass. Its diet includes fruits, leaves, insects, and small vertebrates, with daily food intake ranging from 80 grams to 250 grams. The ground cuscus obtains prey such as beetles, butterflies, flies, Hymenoptera, bedbugs, Orthoptera, dragonflies, mayflies, and net-winged insects.
Размножавање
The uniform cuscus lives on land and develops outside of water bodies. The female carries the offspring in a pouch or mouth on land, with embryonic development lasting 1 week 6 days. Litter size is 1–2 offspring, which immediately after birth crawl into the pouch and remain there for several months. The number of young is 1–2, and the breeding interval is from 8 months to 1 year 1 month. Eggs, eggs, or offspring develop in a terrestrial nest built on the ground or close to it. Maturity occurs at an age from 1 year 1 month to 1 year 11 months.
