Contrasting Thermal Strategies of Montane Neotropical Bats at High Elevations
(2018)
In the Neotropics, captive vespertilionid bats substantially reduce their metabolic rate at low ambient temperatures, similar to their temperate counterparts, whereas the ability of phyllostomids to lower metabolic rate ...
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 ...
Mass movement of individuals at Carara National Park
(2021)
The video shows the movement of individuals of the Green-and-Black Poison Dart Frog, Dendrobates auratus, under rainy conditions. The filmed individuals moved close to the researchers and in close proximity of conspecifics. ...
Diversity patterns, ecological associations and future of research on Costa Rican myxomycetes
(2018-06-05)
The most active research period on myxomycetes in Costa Rica has taken place in the last three decades. During this time, most of the collections have been carried out and most of the scientific articles have been produced. ...

Representa una muestra representativa de la flora y frutos de la Reserva Biológica Alberto Manuel Brenes y ha sido elaborada para personas que empiezan a incursionar en el campo científico y para aquellas aficionadas a las ...
Rotation-Based Mixed Formulations for an Elasticity-Poroelasticity Interface Problem
(2020)
In this paper we introduce a new formulation for the stationary poroelasticity equations written using the rotation vector and the total fluid-solid pressure as additional unknowns, and we also write an extension to the ...
Analysis and mixed-primal finite element discretisations for stress-assisted diffusion problems
(2018)
We analyse the solvability of a static coupled system of PDEs describing the diffusion of a solute into an elastic material, where the process is affected by the stresses exerted in the solid. The problem is formulated in ...
Stability analysis for a new model of multi-species convection-diffusion-reaction in poroelastic tissue
(2020)
We perform the linear stability analysis of a new model for poromechanical processes with inertia (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing and ...
Aritmética para maestros: el número, su operatoria y su enseñanza
(1996)
Es un manual en el que se desarrolla, de una forma sencilla, una posible introducción del niño preescolar y escolar al campo del número y del cálculo aritmético. Se sugieren actividades que tienen una función didáctica ...
