The contrasting roles of aquatic fungi and oomycetes in the degradation and transformation of polymeric organic matter
(2019)
Studies on the ecological role of fungi and, to a lesser extent, oomycetes, are receiving increasing attention, mainly due to their participation in the cycling of organic matter in aquatic ecosystems. To unravel their ...
Ontogeny repeats phylogeny in Steatoda and Latrodectus spiders
(2010)
Web designs of young spiders are often less derived than those of older conspecific individuals. This study tested whether this ‘‘ontogeny repeats phylogeny’’ pattern occurs in two species of Latrodectus and two species ...
Viscid globules in webs of the spider achaearanea tesselata (araneae: theridiidae)
(2006)
We describe the presence and dimensions of viscid globules in both the sheet and tangle portions of the webs of Achaearanea tesselata (Keyserling 1884). We found viscid globules in all sheets and tangles of the webs examined. ...
First Record of the Family Potamocoridae (Hemiptera: Heteroptera) in Costa Rica and of Coleopterocoris Hungerford, 1942 in Central America
(2012)
The Neotropical family Potamocoridae includes nine species in the genera Coleopterocoris Hungerford, 1942 and Potamocoris Hungerford, 1941. The biology of the family is barely known and most of the species mentioned in the ...
Modelo unidimensional de velocidades sísmicas y características tomográficas tridimensionales del Caribe Sur de Costa Rica
(2021-04-22)
El Caribe Sur de Costa Rica fue en 1991 el escenario del último gran terremoto (Mw 7,7) entre la placa Caribe y la microplaca de Panamá. Pese a la alta sismicidad y avances en la cobertura de las redes sísmicas, esa zona ...
Description of the final instar nymphs of seven species from Anacroneuria Klapálek (Plecoptera: Perlidae) in Costa Rica, and first record for an additional genus in Central America
(2011)
The final nymphal stages for seven species of Anacroneuria Klapálek from Costa Rica are described for the first time based upon reared specimens: A. benedettoi Stark, 1998, A. divisa (Navás, 1924), A. holzenthali Stark, ...
Genetic structure in neotropical birds with different tolerance to urbanization
(2022)
Gene flow in birds can be affected by urbanization depending on natural history traits and adaptability
to habitat change. Contrasting results can be expected when comparing species with opposite
resilience to urbanization. ...
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 ...
Uso de una Tabla de Contingencia para Aplicaciones Climáticas
Use of a Contingency Table for Climatic Applications
(2004)
Desde 1997 se han venido realizando en distintas partes de Latinoamérica los llamados Foros Regionales de Predicción Climática (conocidos como RCOFs por sus siglas en inglés), financiados por diversas agencias internacionales ...
Moho structure of Central America based on three-dimensional lithospheric density modelling of satellite-derived gravity data
(2012-05-23)
The Central American isthmus hosts a highly variable Moho structure due to the diverse origin and composition of the crustal basement and the influence of large-scale neotectonic processes. Gravity data from the combined ...
