(Instituto de Ecologia, A.C., 2019)Background and Aims: The group of pteridophytes and lycophytes has been understudied in Honduras, which can be observed in the Río Plátano Man and Biosphere Reserve (RPHBR) that only has 44 species reported. The objective ... -
Response of macroinvertebrate communities to thermal regime in small Mediterranean streams (southern South America): Implications of global warming
(Elsevier GmbH, 2020-03)The seasonal nature of the stream thermal regime has been recognized as an important factor for the structure of benthic macroinvertebrate communities. In this study, we show the importance of temperature and the ... -
Vanilla distribution modeling for conservation and sustainable cultivation in a joint land sparing/sharing concept
(Wiley-Blackwell, 2020-03-01)Vanilla, an expensive but popular spice used in many industries, faces problems related to its supply. Some of these problems are due to the fact that vanilla cultivation is based on clonal material of a single species ... -
Redescription of four species of Camelobaetidius Demoulin, 1966 (Ephemeroptera: Baetidae) from Central and North America
(Magnolia Press, 2020-03-30)Four species of Camelobaetidius (C. maidu, C. variabilis, C. kondratieffi, and C. shepardi) are redescribed and diagnosed based on paratype material and original descriptions. Some omissions and inaccurate information in ... -
Using visible-near-infrared spectroscopy to classify lichens at a Neotropical Dry Forest
(Elsevier B.V., 2020-04)The optical properties of lichens have been traditionally explored in the context of geological mapping where the encrustation of lichens on rocks may influence the detection of minerals of interest. As of today, few studies ... -
The first gynandromorph of the Neotropical bee Megalopta amoena (Spinola, 1853) (Halictidae) with notes on its circadian rhythm
(Pensoft Publishers, 2020-04-27)Gynandromorphy is an anomaly that results in an organism phenotypically expressing both male and female characteristics. Here we describe the first gynandromorph of the bee species Megalopta amoena (Spinola, 1853) (Halictidae, ... -
Environmentally relevant concentrations of silver nanoparticles diminish soil microbial biomass but do not alter enzyme activities or microbial diversity
(Elsevier B.V., 2020-06-05)The increasing use of silver nanoparticles (AgNPs) due to their well-known antimicrobial activity, has led to their accumulation in soil ecosystems. However, the impact of environmental realistic concentrations of AgNPs ... -
Changes in digestive enzymes activities during the initial ontogeny of wolf cichlid, Parachromis dovii (Perciformes: Cichlidae)
(Sociedade Brasileira de Ictiologia, 2019)Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated ... -
Design of a monitoring network as a participative management tool: physical and chemical quality of groundwater in three sub-basins in the Central Valley of Costa Rica
(Universidad Nacional, Costa Rica, 2019-01-31)The groundwater of the Barva, Upper Colima, and Lower Colima aquifers, located in the western part of the Central Valley of Costa Rica represents the main source of drinking water in this region. The purpose of this study ... -
Diversidad microbiana asociada a chenopodiaceae Halotolerantes: Análisis comparativo de comunidades microbianas de suelo, de rizósferas y de microorganismos endofíticos en Suaeda spp y Atriplex spp

Beta diversity and oligarchic dominance in the tropical forests of Southern Costa Rica
(Blackwell Publishing Ltd, 2019-03)Recent studies have reported a consistent pattern of strong dominance of a small subset of tree species in neotropical forests. These species have been called “hyperdominant” at large geographical scales and “oligarchs” ... -

(Elsevier Ltd, 2019-04-19)In the present investigation, we report the growth and hydrogen production of two wild type Chlamydomonas reinhardtii strains isolated from a tropical oxidation pond in Costa Rica. The performance of these two new isolates ... -
Isolation on a remote island: genetic and morphological differentiation of a cosmopolitan odonate
(Nature Publishing Group, 2019-06-01)Although low levels of genetic structure are expected in highly widespread species, geographical and/or ecological factors can limit species distributions and promote population structure and morphological differentiation. ... -
Dietary resource overlap among three species of frugivorous bat in Costa Rica
(Cambridge University Press, 2019-05-03)The maintenance of biodiversity in tropical forests is thought to be dependent on fine-scale mechanisms of niche partitioning that allow species to coexist. This study examined whether three species of short-tailed fruit ... -
Influence of oceanographic conditions on nesting abundance, phenology and internesting periods of east Pacific green turtles
(Springer Verlag, 2019)Sea turtles are migratory animals that travel from foraging grounds to specifc nesting beaches every few years and that, therefore, can be infuenced by oceanographic conditions in several diferent habitats. We assessed ... -
Historical demography of the Caribbean spiny lobster Panulirus argus (Latreille, 1804) (Decapoda: Achelata: Palinuridae) in the Florida Keys, USA inferred using single nucleotide polymorphisms (SNPs)
(Oxford University Press, 2019)The Caribbean spiny lobster Panulirus argus (Latreille, 1804) is an important species in shallow-water coral reefs and target of the most lucrative fishery in the Caribbean Sea. We explored historical demography in P. argus ... -
