Article
Mazama temama is the smallest red deer in Central America. It was one of the first species described for the genus, and until the end of the last century many authors considered it as a subspecies of Mazama americana due to morphological similarities. Cytogenetic studies of animals in captivity have shown different karyotypes that led to its recog...
Article
In forest ecosystems, particularly those in the tropics, the occurrence of rapid transformation impacts the wildlife. Most of the studies on fauna have been conducted on pristine and protected areas, with less consideration of lands and landscapes dedicated to diverse human activities. This is particularly true for medium and large-sized mammals, w...

The Central American brocket deer is a vulnerable species. Geographically isolated populations have been affected by poaching and habitat fragmentation, leading to local extinctions. It is therefore important to understand this species’ habitat characteristics, particularly of resting sites, which play a crucial role in survival and fitness. We des...

As human modification of primate habitats expands, overlapping use of resources and conflict between people and primates are becoming more common, particularly at the forest–farm edge where primates feed on crops. Although there is anecdotal evidence that the white-faced capuchin monkey (Cebus imitator) feeds on crops in Panama, to our knowledge fa...

White-tailed deer is a sensitive species and can easily get stressed. Human activities associated with ecotourism and hunting (such as the creation of enclosures), as well as environmental factors can trigger stress. It is necessary to know the hormonal stress and reproductive levels for a better management and conservation of the species. The aim...

Core activity areas are the most important sites within an animal's home range as they contain the greatest density of critical resources. Because these areas are small and intensively used, they can affect the total distances covered by animals searching for resources. Our objective was to document which habitat variables affect core area selectio...

Sexual segregation in the white-tailed deer is very common in temperate habitats. Two main hypotheses have been used to explain this pattern: one based on the differential risk of predation between the sexes and the other, sexual dimorphism. We evaluated whether sexual segregation is occurring in a tropical population of white-tailed deer by examin...
