Vocal behavior and the use of social information during roost finding
(2022-07-26)
When selecting feeding, hiding, or resting areas, animals face multiple
decisions with different fitness consequences. To maximize efficiency,
individuals can either collect personal information, or use information
gathered ...
Plant diversity in the diet of Costa Rican primates in contrasting habitats: a meta-analysis
(2023)
In human-modified tropical landscapes, the survival of arboreal vertebrates, particularly primates, depends on their plant dietary diversity. Here, we assessed diversity of plants included in the diet of Costa Rican ...
Velocity‑vorticity‑pressure formulation for the Oseen problem with variable viscosity
(2021)
We propose and analyse an augmented mixed finite element method for the Oseen equations written in terms of velocity, vorticity, and pressure with non-constant viscosity and homogeneous Dirichlet boundary condition for the ...
Incorporating variable viscosity in vorticity-based formulations for Brinkman equations
Intégration de la viscosité variable dans des formulations en tourbillon pour les équations de Brinkman
(2019-06)
In this brief note, we introduce a non-symmetric mixed finite element formulation for Brinkman equations written in terms of velocity, vorticity, and pressure with non-constant viscosity. The analysis is performed by the ...
Strong individual signatures and weaker group signatures in contact calls of Spix’s disc-winged bat, Thyroptera tricolor
(2012-01)
Spix’s disc-winged bats, Thyroptera tricolor, form small, long-term social groups in which members are
loyal to a patch of forest but move on a daily basis between highly ephemeral roosting sites (partly unfurled Heliconia ...
A mixed-primal finite element method for the coupling of Brinkman-Darcy flow and nonlinear transport.
(2021-01)
This paper is devoted to the mathematical and numerical analysis of a model describing the interfacial
flow-transport interaction in a porous-fluidic domain. The medium consists of a highly permeable
material, where the ...
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
(2007-04)
We examined variation in foraging- and roosting-range size in the tent-making bat Artibeus watsoni. We radiotracked 42 individuals at 2 sites in the Golfito Wildlife Refuge and 6 sites at Corcovado National Park, southwestern ...
Seasonality in the emission of contact calls in Spix’s disc-winged bats(Thyroptera tricolor) suggests a potential role in mate attraction
(2022)
Multiple studies show that animals exhibit consistent individual differences in behavior, but they also experience short-term changes
in their behavioral responses associated with seasonal events, most notably reproduction. ...
Calling for more accurate information in aquarium trade: analysis of live-fish import permits in Costa Rica
(2017)
Ornamental fish trade is a growing business around the world, but also a major pathway for the introduction of potentially invasive species. Trade patterns and policies have been evaluated in high-income countries while ...
Analysis of a vorticity–based fully–mixed formulation for 3D Brinkman–Darcy problem.
(2016)
We propose and analyze a fully-mixed finite element method to numerically approximate the flow patterns of a viscous fluid within a highly permeable medium (an array of low concentration fixed particles), described by ...
