Echinoderm diversity of a tropical estuary in the largest river basin of the Costa Rican Pacific, Eastern Tropical Pacific
Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports ...
Gastropods and bivalves taken as by-catch in the deep-water shrimp trawl-fishery along the Pacific coast of Costa Rica, Central America
Deep-water habitats are among the least studied but most vulnerable environments. By-catch data from deep-water fisheries in Latin America are limited, and detailed reports on associated molluscs are scarce. This study ...
New records of gelatinous zooplankton from an oceanic island in the Eastern Tropical Pacific
Gelatinous zooplankton are an abundant and diverse group of animals in the pelagic environment. However, knowledge of species diversity and spatial distributions, as well as their ecological role, is scarce. We present ...
Ecological assessments of the coral reef communities in the Eastern Caribbean and the effects of herbivory in influencing coral juvenile density and algal cover
Caribbean reefs have been unevenly surveyed, with many areas lacking baseline data. In this study, the current status of Orbicella reefs, a structurally complex forereef habitat, was quantified in an understudied region, ...
New record of the starfish Ophidiaster ludwigi (Echinodermata: Asteroidea) from the Paciﬁc of Mexico and Costa Rica
Ophidiaster ludwigi had been reported only from Panama and Peru. Here we add record of the genus and species for Mexico and Costa Rica; and, first time its bathymetric distribution (0-156 m)
Los accidentes acuáticos alrededor de nuestras costas y su relación con el estado del mar y de la atmósfera
Se hace una revisión de los principales fenómenos océano-atmosféricos que pueden producir accidentes acuáticos en nuestras costas, describiendo sus características, propagación y orígenes. Se recopilaron varios casos ...

Three specimens of the rare scyphozoan Stellamedusa ventana Raskoff & Matsumoto, 2004 were collected during a vertical plankton tow on April 2013 in a shallow bay on the Eastern Tropical Pacific that was sampled eight times ...
Seagrass morphometrics at species level in Moreton Bay, Australia from 2012 to 2013
Seagrass above, below and total biomass, density and leaf area, length and width were quantified at a species level for 122 sites over three sampling periods in Moreton Bay, Australia. Core samples were collected in two ...
Análisis de datos de CTD de campañas oceanográficas recientes en el Pacífico Tropical del Este, Costa Rica
Un CTD es un instrumento oceanográfico el cual permite medir la conductividad, temperatura y presión. Los datos producidos por un CTD permiten calcular otras variables como la salinidad. La información generada permite la ...
