Bat Assemblages along an Elevational Gradient in Costa Rica
(2022)
Spatio-temporal patterns of species richness, Hill numbers, captures per species, feeding guilds, sex ratio, and biomass were studied
in a Neotropical bat assemblage during 17 continuous months in four bands (low: 50–150, ...
Potential vibratory signal performed by a male
(2021)
(English) The video shows the vibratory movement of the fourth toe performed by a male of the Green-and-Black Poison Dart Frog, Dendrobates auratus, at Carara National Park. The toe-tapping behaviour was performed in front ...
Signal repertoire and contest outcome in the Jacky dragon
(2016)
Establishing dominance is an important mechanism for determining access to
resources such as mates or territories. However, levels of aggression and dominance
may vary among populations based on history and variation in ...
Sound amplification by means of a horn-like roosting structure in Spix's disc-winged bat
(2013-10)
While sound is a signal modality widely used by many animals, it is very susceptible to attenuation, hampering effective long-distance communication. A strategy to minimize sound attenuation that has been historically used ...
When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
(2013-11)
For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ...

Las aves oceánicas o pelágicas son aquellas que están adaptada al océano abierto y pasan la mayor parte de su vida lejos de la tierra (Harrison et al. 2021), aunque pueden reportarse en ecosistemas costeros de forma ...
Effect of temperature on the visual displays of the Jacky dragon
(2019)
In ectotherms such as lizards, temperature is a key determinant of their behavior and their ability to signal to conspecifics. We asked whether changes in the thermal environment along the distribution of an agamid lizard, ...

An updated analysis of myxomycete diversity in Costa Rica is provided herein as a product of
an extensive data mining-based study intended to normalize the information on myxomycetes from
that country. Within the context ...
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 ...
