Habitat
This species primarily inhabits dry forests, shrublands, and grasslands in central South America, including Bolivia, Paraguay, and Argentina. They prefer areas with dense undergrowth and rocky outcrops for shelter, often at elevations up to 2,000 meters.
Diet
The Buff-bellied fat-tailed mouse opossum is omnivorous, feeding on insects such as beetles and crickets, small vertebrates like lizards, and fruits or seeds from native plants. They forage nocturnally, using their keen senses to hunt or scavenge in underbrush.
Behavior
This opossum is solitary and nocturnal, spending its days hidden in nests made of leaves or rock crevices and emerging at night to forage. It exhibits territorial behavior by marking areas with scent glands and may enter torpor during cold weather to conserve energy. They are agile climbers, using their tails for balance in trees or shrubs.
Conservation Status
The IUCN classifies the Buff-bellied fat-tailed mouse opossum as Least Concern, with a stable population trend, though habitat loss due to agriculture and deforestation poses a potential threat.
