Ontogeny of an interactive call-and-response system in Spix's disc-winged bats
(2020)
We investigated the ontogenetic changes of two call types, the inquiry call and the response call, which comprise an interactive communication system in Spix's disc-winged bats, Thyroptera tricolor. We documented structural ...
Morphological and ecological variation of a tropical anoline lizard: are agonistic interactions shaping ecomorphological relationships?
(2018)
Ecologists have long been intrigued by which factors influence habitat use by an organism and how communities are structured. However, the links between habitat preferences, morphology, biotic interactions and community ...
Effect of exposition to chlorpyrifos upon plasmatic cholinesterases, hematology and blood biochemistry values in Bothrops asper (Serpentes: Viperidae)
(2018)
The terciopelo (Bothrops asper), is one of the most important venomous snakes in Costa Rica and common on agriculture where insecticides are frequently used for pest control. To assess the exposure to
organophosphates on ...
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)
Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may
disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ...

A partir de 1978 se incician las actividades docentes-administrativas y de investigación en la Reserva Biológica, por lo que se hizo necesario conocer su biodiversidad.Este proyecto de tuvo como objetivos: conocer la ...
Vocal behavior and the use of social information during roost finding
(2022-07-26)
When selecting feeding, hiding, or resting areas, animals face multiple
decisions with different fitness consequences. To maximize efficiency,
individuals can either collect personal information, or use information
gathered ...
Plant diversity in the diet of Costa Rican primates in contrasting habitats: a meta-analysis
(2023)
In human-modified tropical landscapes, the survival of arboreal vertebrates, particularly primates, depends on their plant dietary diversity. Here, we assessed diversity of plants included in the diet of Costa Rican ...
Strong individual signatures and weaker group signatures in contact calls of Spix’s disc-winged bat, Thyroptera tricolor
(2012-01)
Spix’s disc-winged bats, Thyroptera tricolor, form small, long-term social groups in which members are
loyal to a patch of forest but move on a daily basis between highly ephemeral roosting sites (partly unfurled Heliconia ...
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
(2007-04)
We examined variation in foraging- and roosting-range size in the tent-making bat Artibeus watsoni. We radiotracked 42 individuals at 2 sites in the Golfito Wildlife Refuge and 6 sites at Corcovado National Park, southwestern ...
Seasonality in the emission of contact calls in Spix’s disc-winged bats(Thyroptera tricolor) suggests a potential role in mate attraction
(2022)
Multiple studies show that animals exhibit consistent individual differences in behavior, but they also experience short-term changes
in their behavioral responses associated with seasonal events, most notably reproduction. ...
