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 ...
Formulation and analysis of fully-mixed methods for stress-assisted diffusion problems
(2019-03)
This paper is devoted to the mathematical and numerical analysis of a mixed-mixed PDE system describing the stress-assisted diffusion of a solute into an elastic material. The equations of elastostatics are written in mixed ...
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 ...

(2023-07)
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, ...

(2018-04)
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 ...
Phenology of myxomycetes in Turrialba, Costa Rica
(2021-05)
Long-term monitoring and phenological patterns
of microbial communities are rare in the scientific
literature. Myxomycetes have life cycle characteristics
that allow both to be documented. The present
study summarizes ...
Taxonomic Keys and Plates from The Myxomycetes
(2021-04-01)
In 1969, George W. Martin and Constantine J. Alexopoulos published a remarkable work on myxomycetes. Their monograph on this group of organisms became one of the references to the taxonomy and geographical distribution of ...
