Introduction
Know and understand the functional diversity of mammals, their ecological importance, and its relationship to ecosystem services. To do this: Analysis of local distribution patterns of mammals. Mechanisms that regulate the structure of the local assembly in natural and transformed landscapes. Use and habitat preference. Activity patterns, diet and foraging behavior. Models of conservation of mammals that integrate social, economic and biological components in crop and livestock systems.

Coxiella burnetii is the etiologic agent of Q fever, a zoonotic infectious disease of worldwide distribution that has a wide clinical spectrum. Transmission of C. burnetii occurs by inhalation of contaminated secretions and excreta of infected animal species, particularly goats, cattle and sheep. Activities associated with livestock contact represe...

Leptospirosis is caused by pathogenic Leptospira spp., which can be found in nature among domestic and wild animals. In Colombia, the Macaregua cave is known for its bat richness; thus, because bats are reservoir hosts of human microbiological pathogens, we determined if the Macaregua cave bats harbored Leptospira in the wild. A total of 85 kidney...

When fruit bats forage, they serve an important ecological function, as is seed dispersal. Although several authors have approached the significance of bats in generating ecosystem services, there is a gap in understanding the importance of the seed dispersal by fruit bats for ecosystems and society. To fill this gap, we considered different compon...

Climate change can cause geographic displacement of the ecological niche of a species, so that similar species that previously did not coexist could begin to face new interactions. Such geographic displacement and increased competition can also be exacerbated by anthropic intervention. Until less than 100 years ago, Vultur gryphus and Coragyps atra...

Neotropical frugivorous bats display a trophic structure composed of bat species with dietary preferences of core plant taxa (Artibeus-Ficus + Cecropia, Carollia-Piper, Sturnira-Solanum + Piper). This structure is hypothesized to be an ancestral trait, suggesting that similar diets would be observed throughout a species' range. However, most eviden...
