DNA-assisted identification of Caulerpa (Caulerpaceae, Chlorophyta) reduces species richness estimates for the Eastern Tropical Pacific
Taxonomy and species richness estimates for the genus Caulerpa have proven challenging due to the difficulty of assessing morphological species limits. In the present study we evaluate the taxonomy of the genus and assess ...
Homoplasious colony morphology and mito-nuclear phylogenetic discordance among Eastern Pacific octocorals
Octocorals are a diverse and ecologically important group of cnidarians. However, the phylogenetic relationships of many octocoral groups are not well understood and are based mostly on mitochondrial sequence data. In ...
Interannual variability of the midsummer drought in Central America and the connection with sea surface temperatures
The midsummer drought (MSD) in Central America is characterised in order to create annual indexes representing the timing of its phases (start, minimum and end), and other features relevant for MSD forecasting such as the ...
Variability of the Caribbean low-level jet during borealwinter: large-scale forcings
An index capturing the anomalies of the zonal wind at 925 hPa from 1950 to 2010 was defined to explore the relationship between the fluctuations of the Caribbean low-level jet (CLLJ) and the main climate variability modes ...
New records of snipe eels (Anguilliformes: Nemichthyidae) from the Pacific coast of lower Central America
Background: New records of occurrence of two snipe eels (Avocettina bowersii and Nemichthys scolopaceus), poorly known for the Pacific coast of Costa Rica and Panama are herein reported. Results: Specimens, 45 in total ...
A new species of Leptoderma Vaillant, 1886 (Osmeriformes: Alepocephalidae) from the Pacific coast of Central America
A new species of Leptoderma Vaillant, 1886 is described from a single specimen trawled at 1368–1406 m depth off El Salvador, Central America, tropical eastern Pacific. Leptoderma ospesca n. sp. can be readily distinguished ...
Distribución espacial de impactos de eventos hidrometeorológicos en América Central
América Central está expuesta a la ocurrencia de eventos hidrometeorológicos a lo largo del año y los impactos que estos pueden provocar van a estar mayormente localizados en áreas donde las variables tanto naturales como ...
Metals in coastal mollusks of Costa Rica
Metales en moluscos costeros de Costa Rica
The input of contaminants to coastal ecosystems is a global problem on the rise. Data on metal pollution from tropical sites is often lacking and pilot surveys are urgently needed to provide a general framework to estimate ...
The early rainy season in Central America: the role of thetropical North Atlantic SSTs
We explored the relationship between the precipitation anomalies during May to June as the first peak of the rainy season in the Pacific slope of Central America, and sea surface temperature (SST) fluctuations in the ...
Productividad primaria en el Humedal Nacional Térraba-Sierpe, Costa Rica
Primary productivity in the National Térraba-Sierpe Wetland, Costa Rica
Se determinó la productividad primaria (PP) del fitoplancton en un amplio sector del Humedal Nacional Térraba Sierpe (HNTS) de Costa Rica, durante la estación lluviosa del año 2008 y en la estación seca del año 2009. Seis ...
