Behavioural responses of reptiles to visitors of protected areas in Costa Rica
(2016)
Tourists can have a strong impact on the behaviour of wild animals, modifying
foraging strategies, diet and habitat use, increasing stress, and altering communication
and escaping behaviour. Such behavioural changes have ...
Comparing the efficiency of monofilament and traditional nets for capturing bats
(2021)
Traditional mist nets used for capturing bats have several drawbacks, particularly that they are inefficient at sampling many insectivorous species. One possible alternative is to use monofilament nets, whose netting is ...
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 ...
Plan de manejo y desarrollo de la Reserva Biológica Alberto Ml. Brenes: versión para discusión
(2014-01-21)
Expone un plan de manejo y desarrollo para la Reserva Biológia Alberto Manuel Brenes, la cual es administrada por la Universidad de Costa Rica. Es un instrumento de planificación orientador de todas las acciones que deben ...
New mixed finite element methods for natural convection with phase-change in porous media
(2019)
This article is concerned with the mathematical and numerical analysis of a steady phase change problem for non-isothermal incompressible viscous flow. The system is formulated in terms of pseudostress, strain rate and ...
Twofold Saddle-Point Formulation of Biot Poroelasticity with Stress-Dependent Diffusion
(2023)
We present a new stress/total-pressure formulation for poroelasticity that incorporates the coupling with steady nonlinear diffusion modified by stress. This nonlinear problem is written in mixed-primal form, which combines ...
Finite Element Methods for Large-Strain Poroelasticity/Chemotaxis Models Simulating the Formation of Myocardial Oedema
(2022-07-22)
In this paper we propose a novel coupled poroelasticity-diffusion model for the formation of
extracellular oedema and infectious myocarditis valid in large deformations, manifested as an interaction between interstitial ...
A posteriori error analysis of mixed finite element methods for stress-assisted diffusion problems
(2022)
We develop the a posteriori error analysis for mixed-primal and fully-mixed finite element methods approximating the stress-assisted diffusion of solutes in elastic materials. The systems are formulated in terms of stress, ...
Cambio Climático en América Central, proyecciones hidrológicas e impactos en el Corredor Seco Centroamericano
(2022-12-07)
Se presentan nueve infografías relacionadas con los impactos del Cambio Climático en América Central en las variables precipitación y temperatura, así como sus repercusiones en la agricultura y biodiversidad. También se ...
Caracterización fisicoquímica del agua superficial en la subcuenca del río La Paz, San Ramón, Alajuela Costa Rica; como indicador del impacto ambiental por urbanismo en la zona
(2020)
El río La Paz es uno de los afluentes del río Barranca ubicado en el distrito Piedades Norte de San Ramón. Esta zona se caracteriza por ser montañosa de población rural en crecimiento, en la que se llevan a cabo actividades ...
