Differences in plasmatic butyrylcholinesterases (BChE) values between Pacific and Caribbean populations of terciopelo (Bothrops asper) in Costa Rica
(2019)
The terciopelo (Bothrops asper) inhabits human-modified environments such as agricultural areas, becoming more prone to be exposed to organophosphate insecticides. These chemicals can inhibit plasmatic butyrylcholinesterases ...
Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)
In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ...
A call-and-response system facilitates group cohesion among disc-winged bats
(2013)
Acoustic signals are important in maintaining group cohesion, particularly in highly mobile species. For these signals to facilitate group cohesion, individuals must be able to recognize, and respond to, calls emitted by ...
Mosses as spore traps for myxomycetes
(2020-07-06)
Small-mesh nylon bags filled with autoclaved samples of mosses were placed out in the field in northwest Arkansas and central Costa Rica to assess the extent to which mosses could serve as spore traps for myxomycetes. The ...
La investigación en la Reserva Biológica Alberto ML. Brenes (Área de Conservación Arenal - Tilarán)
(2000)
El documento se refiere a las actividades de investigación en la Reserva Biológica Alberto Manuel Brenes (RBAMB), ubicada en San Ramón de Alajuela y administrada por la Universidad de Costa Rica, por medio de la Sede de ...
Informe técnico sobre la importancia biológica de la Reserva Forestal de San Ramón
(1991-04)
En el documento se presenta una síntesis de las actividades de investigación que se han llevado a cabo en la Reserva Forestal de San Ramón, en las que han participado investigadores de la Universidad de Costa Rica y el ...
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 ...
A posteriori error analysis of a fully-mixed formulation for the Brinkman–Darcy problem
(2017-09-05)
We develop the a posteriori error analysis for a mixed finite element method
applied to the coupling of Brinkman and Darcy equations in 3D, modelling the interaction of viscous and non-viscous flow effects across a given ...
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. ...
