Environmental Drivers and Distribution Patterns of Carnivoran Assemblages (Mammalia: Carnivora) in the Americas: Past to Present
Ecological niche modeling and macroecological approach in order to assess whether constraints patterns in carnivoran richness and composition structures in replicated assemblages through time and space should reflect environmental filtering through ecological niche constraints from the Last Inter-glacial (LIG), Last Glacial Maximum (LGM) to the present (C) time

Survival analysis of two endemic lizard species before, during and after a rat eradication attempt on Desecheo Island, Puerto Rico
The combination of studies such as these can help managers make informed decisions about the potential negative impacts of rodenticides used during eradication operations versus the expected positive impact to native biota from the permanent removal of threats posed by invasive species.

Food habits of puma (Puma concolor) in the Andean areas of Tamá National Natural Park and its buffer zone, Colombia
Even though the puma (Puma concolor) is the second largest felid in America and is widely distributed in both the continent and in Colombia. Knowledge about its food habits in many areas of the Neotropics, especially in the highlands, is still limited. We surveyed nine localities in Tamá NNP (National Natural Park) and its buffer zone. This...

Multi‑criteria spatial identification of carnivore conservation areas under data scarcity and conflict: a jaguar case study in Sierra Nevada de Santa Marta, Colombia
Knowledge about carnivore species in data-poor countries, such as Colombia, is scarce which has the potential to result in poor landscape planning decisions. We present a multi-criteria spatial identification tool for conservation and management areas, focused on Jaguars (Panthera onca) in the Sierra Nevada de Santa Marta, in northern Colombia

MINERAL-LICK USE BY CHOLOEPUS HOFFMANNI (PILOSA: MEGALONYCHIDAE) AT LAS CRUCES BIOLOGICAL STATION, COTO BRUS, COSTA RICA
Hasta la fecha, solo existe un registro del consumo de minerales en perezosos (i.e., Choloepus didactylus) en Ecuador. Aquí presentamos el primer registro del consumo mineral para C. hoffmanni en una selva tropical en Costa Rica. Este comportamiento se ha asociado principalmente con procesos de desintoxicación en herbívoros, pero no existe evidencia de tales necesidades en perezosos.

Communal egg-laying and thermal isolation in a nest of Erythrolamprus epinephelus (Dipsadidae)
This data showed that nest cavity maintained low thermal fluctuation despite large fluctuations of external temperature, which could be favorable to hatchling development. The physiological and behavioral benefits to both females and offspring must be studied in more detail for Neotropical snakes.
