New records of myxomycetes for the state of Veracruz from Cofre de Perote National Park
(2021-09-20)
Most of the species of myxomycetes from Mexico are well documented, but their patchy geographical
and temporal distribution responds to the individual efforts carried out in different areas of the territory over time.

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 ...
Well-posedness and discrete analysis for advection-diffusion-reaction in poroelastic media
(2021)
We analyse a PDE system modelling poromechanical processes (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing and reacting solutes in the medium. We ...
Kinship, association, and social complexity in bats
(2019-01)
Among mammals, bats exhibit extreme variation in sociality, with some species living largely solitary lives while others form colonies of more than a million individuals. Some tropical species form groups during the day ...
An augmented mixed–primal finite element method for a coupled flow–transport problem
(2015)
In this paper we analyze the coupling of a scalar nonlinear convection-diffusion problem with the Stokes equations where the viscosity depends on the distribution of the solution to the transport problem. An augmented ...
A posteriori error analysis of a semi-augmented finite element method for double-diffusive natural convection in porous media
(2024)
This paper presents our contribution to the a posteriori error analysis in 2D and 3D of a semi-augmented mixed-primal finite element method previously developed by us to numerically solve double-diffusive natural convection ...
Stability of a second-order method for phase change in porous media flow
(2018)
We analyse the stability of a second-order finite element scheme for the primal formulation of a Brinkman-Boussinesq model where the solidification process influences the drag and the viscosity. The problem is written in ...
Composition and species richness of the herpetofauna of a Costa Rican University campus
(2019)
The campus of the University of Costa Rica in Limón port city, Costa Rica, known as Sede del Caribe (SC),
includes a secondary forest of ca. 40 years old. This forest holds a great potential for environmental education, ...
Can the location of the isolation laboratory affect the generation of myxomycete data using moist chambers? An experiment in the Neotropics
(2021-03-11)
The moist chamber technique, as it is used in myxomycete research, is an extremely useful method to optimize project resources. However, as it occurs with any laboratory-based protocol, the usefulness of this technique ...
Occurrence of pharmaceuticals, hazard assessment and ecotoxicological evaluation of wastewater treatment plants in Costa Rica
(2020)
The continuous release of pharmaceuticals from WWTP effluents to freshwater is a matter of concern, due to their potential effects on non-target organisms. The occurrence of pharmaceuticals in WWTPs and their associated ...
