Aridity Trends in Central America: A Spatial Correlation Analysis
(2020-04-23)
Trend analyses are common in several types of climate change studies. In many cases, finding evidence that the trends are different from zero in hydroclimate variables is of particular interest. However, when estimating ...
Recuento de la sismicidad en Costa Rica durante el 2019

Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera
(2019)
Certain color patterns in insects show convergent evolution reflecting potentially important biological functions,
for example, aposematism and mimicry. This phenomenon has been most frequently documented in Lepidoptera
and ...
Spectral measure of color variation of black-orange-black (BOB) pattern in small parasitoid wasps (Hymenoptera: Scelionidae), a statistical approach
(2019)
Small parasitoid wasps are abundant and extremely diverse, yet their colors have not been analyzed. One of the more common color patterns observed in these wasps is a black-orange-black pattern, which is especially common ...

(2019)
Jumping spiders were sampled for 24 months in a Costa Rican urban environment and one
of the species collected, Lyssomanes jemineus, was observed in detail in order to document its
phenology in this disturbed habitat. ...
Bile salts and derivatives: Rigid unconventional amphiphiles as dispersants, carriers and superstructure building blocks
(2015)
Steroidal surfactants like bile salts have a rigid amphiphilic structure significantly different from the typical head–tail one. As a result, these molecules show peculiar features in their self-assembly behavior and ...
New insights into the molecular phylogeny of the swimming crabs of the genera Portunus Weber, 1795 and Achelous De Haan, 1833 (Brachyura: Portunidae) of the Americas
(2018)
Earlier studies of swimming crabs (family Portunidae) in the Americas suggested polyphyly of Portunus Weber, 1795. Our previous molecular analyses provided evidence for a subdivision of the genus, resulting in a reassignment ...
Novelties in Costa Rican Stelis (Orchidaceae: Pleurothallidinae): two new species and a new record in the "Dracontia group"
(2017)
Stelis dies-natalis and Stelis aenigma, belonging to a group of mostly Middle American species alternatively placed in genus Dracontia, are described and illustrated based on living material. They were both ...
