Elasmobranch bycatch associated with the shrimp trawl fishery off the Pacific coast of Costa Rica, Central America
Demersal sharks and rays are common yet vulnerable components of the bycatch in tropical bottom-trawl fisheries. Little is known about the elasmobranch assemblages associated with most of these fisheries, particularly ...
Occurrence of the tripodfish Bathypterois ventralis (Aulopiformes: Ipnopidae) in the Pacific coast of Costa Rica
Presencia del pez trípode Bathypterois ventralis (Aulopiformes: Ipnopidae) en la costa pacífica de Costa Rica
Between 1990 and 1992, 2 adult specimens of the ventrad spiderfish, Bathypterois ventralis Garman 1899, were collected at depths between 637 and 880 m off the Pacific coast of Costa Rica. These specimens constitute the ...

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 ...
Systematics and biogeography of Pleurobranchus Cuvier, 1804, sea slugs (Heterobranchia: Nudipleura: Pleurobranchidae)
Species of Pleurobranchus (Mollusca: Gastropoda: Heterobranchia: Nudipleura: Pleurobranchidae) are commonly found worldwide, but there is a substantial amount of confusion regarding the ranges and identification of individual ...
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 ...
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 ...
Using eDNA to determine the source of organic carbon in seagrass meadows
Seagrasses sequester globally significant amounts of carbon (C), which is stored mainly in the sediment. BothC fixation by the seagrass (autochthonous) and the trapping of organic matter that is derived from outside ...
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 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 ...
