Establishment of Epiphytic Bromeliads in Successional Tropical Premontane Forests in Costa Rica
(2008)
Plant community composition is the combined result of species‐specific competitive abilities and the availability of propagules. For epiphytic plants, current hypotheses consider that dispersal‐related factors are most ...

Spatial genetic structure within size classes of the endangered tropical tree Guaiacum sanctum (Zygophyllaceae)
(2010)
Premise of the study: Patterns of spatial genetic structure (SGS) were analyzed within a population of the endangered tropical tree Guaiacum sanctum located in northwestern Costa Rica. Documentation of these patterns ...
Functional aspects of genital differences in Leucauge argyra and L. mariana (Araneae: Tetragnathidae)
(2013)
Morphological studies have documented the tendency for male genitalia to diverge rapidly compared to other body parts in many animal groups, including spiders. But documentation of how differences in genital structures of ...

Life history characteristics of five species of Baetidae were investigated over a one-year period at Quebrada Gonza´ lez, a warmwater stream in Braulio Carrillo National Park. Larvae of three species of Baetodes and two ...
Wasp florivory decreases reproductive success in an epiphytic bromeliad
(2009)
Flower predation or florivory may alter the sexual expression, floral display, and reduce the reproductive success in plants. In this article, we estimated the effect of florivory on the reproductive success of the epiphytic ...
Phylogenetic analysis of ITS data from endophytic fungi using massive parallel bayesian tree inference with exabayes
Análisis filogenético de secuencias ITS provenientes de hongos endófitos utilizando inferencia bayesiana paralela de árboles con exabayes
(2020-03-27)
Ecological studies of fungal communities have been favored thanks to the emergence and improvement of independent culture techniques that use the ITS region as a molecular marker. This has allowed a more accurate identification ...
Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
(2019)
Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species ...
