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 ...
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 ...
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 ...
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 ...
A mixed-primal finite element approximation of a sedimentation–consolidation system
(2016)
This paper is devoted to the mathematical and numerical analysis of a strongly cou- pled flow and transport system typically encountered in continuum-based models of sedimentation–consolidation processes. The model focuses ...
Effect of exposition to chlorpyrifos upon plasmatic cholinesterases, hematology and blood biochemistry values in Bothrops asper (Serpentes: Viperidae)
(2018)
The terciopelo (Bothrops asper), is one of the most important venomous snakes in Costa Rica and common on agriculture where insecticides are frequently used for pest control. To assess the exposure to
organophosphates on ...
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)
Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may
disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ...
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 ...
Inventario florístico de la Reserva Biológica Alberto Ml. Brenes en San Ramón
(2014-01-28)
A partir de 1978 se incician las actividades docentes-administrativas y de investigación en la Reserva Biológica, por lo que se hizo necesario conocer su biodiversidad.Este proyecto de tuvo como objetivos: conocer la ...
