collared mangabey

The Collared Mangabey, known scientifically as <em>Cercocebus torquatus</em>, is an Old World monkey belonging to the family Cercopithecidae. As a member of the genus Cercocebus, <em>Cercocebus torquatus</em> is recognised by its distinctive appearance, which typically includes a pale or white collar of fur around the neck region that contrasts with darker body colouration, lending the species its common name. Collared Mangabeys are typically associated with tropical rainforest habitats, particularly swamp forests and riverine forest environments, where they forage for fruits, seeds, invertebrates, and other food items on both the ground and in the canopy. The species is known for its loud, distinctive calls, which are used for communication across forest territories. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Mangabey is currently assessed as Endangered on the IUCN Red List, primarily due to ongoing habitat loss from forest clearance and hunting pressure across its range.

Colombian Oldfield Mouse

<em>Thomasomys dispar</em>, commonly known as the Colombian Oldfield Mouse, is a small rodent species belonging to the genus <em>Thomasomys</em> within the family Cricetidae. This species is classified as Data Deficient, indicating that insufficient information is currently available to evaluate its conservation status with confidence. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Thomasomys</em> are typically associated with high-altitude Andean habitats, including páramo grasslands, shrublands, and montane forest edges, where they occupy ground-level microhabitats and burrow in soft soils. These mice are generally omnivorous, consuming seeds, plant material, and invertebrates, though specific dietary data for <em>Thomasomys dispar</em> have not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification highlights the need for targeted surveys in Colombian Andean regions to determine population size, distribution, and the ecological requirements of this poorly known rodent.
