The extraordinary evolutionary history of the reticuloendotheliosis viruses [PDF]

, 2013
The reticuloendotheliosis viruses (REVs) comprise several closely related amphotropic retroviruses isolated from birds. These viruses exhibit several highly unusual characteristics that have not so far been adequately explained, including their extremely

Sloths host Anhanga virus‐related phleboviruses across large distances in time and space [PDF]

, 2019
Sloths are genetically and physiologically divergent mammals. Phleboviruses are major arthropod-borne viruses (arboviruses) causing disease in humans and other animals globally. Sloths host arboviruses, but virus detections are scarce.

Distribution and current state of knowledge of Hoffmann’s two-toed sloth (Choloepus hoffmanni) in Colombia, with comments on the variations of its external morphological traits

, 2016
Hoffmann's two-toed sloth ( Choloepus hoffmanni ) has been extensively studied since the 1940s in some countries across its distribution range.  However, several aspects of its biology remain unexplored or have only been described superficially.

Food habits of the Cougar Puma concolor (Carnivora: Felidae) in the Central Andes of the Colombian Coffee Region [PDF]

, 2020
The feeding habits of the cougar have been scarcely studied in Colombia, despite its importance in the ecosystems it inhabits. In this study, we analysed the diet of the cougar using 53 feces samples collected from several sites in the Central Andes of ...

Blood parameters and reproductive hormone profile of female Choloepus hoffmanni in captivity

Revista de Biología Tropical, 2017
El uso de técnicas no invasivas ni estresantes para determinar perfiles hormonales, como la medición de esteroides fecales, ha incrementado la comprensión de la fisiología reproductiva en animales silvestres. Debido a la escasa información con respecto a perfiles hormonales reproductivos del perezoso de dos dedos, Choloepus hoffmani, se realizó un ...

Parámetros sanguíneos y perfil de hormonas reproductivas de hembras de Choloepus hoffmanni en cautiverio

, 2017
In wild animal species, the use of non-invasive and non-stressful procedures to determine hormone profiles, such as fecal steroid measurements, has considerably increased the comprehension of their reproductive physiology.
