(2016)Los manglares tienen gran importancia ecológica, económica, riqueza natural y prestan servicios ambientales. No obstante, son amenazados por la sobreexplotación, la contaminación y el cambio de uso de suelo. Costa Rica ... -
Echinoderm diversity of a tropical estuary in the largest river basin of the Costa Rican Pacific, Eastern Tropical Pacific
(2017)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 ... -
Ecological assessments of the coral reef communities in the Eastern Caribbean and the effects of herbivory in influencing coral juvenile density and algal cover
(2017)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, ... -
Elasmobranch bycatch associated with the shrimp trawl fishery off the Pacific coast of Costa Rica, Central America
(2015)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 ... -
Fishes from the Tusubres River basin, Pacific coast, Costa Rica: checklist, identification key and photographic album
(2015-05)A checklist of the fishes of the Tusubres River basin, Pacific coast of Costa Rica, compiled from field and museum surveys is herein presented. A total of 54 species, representing 47 genera and 27 families, were recorded. ... -
Gastropods and bivalves taken as by-catch in the deep-water shrimp trawl-fishery along the Pacific coast of Costa Rica, Central America
(2017)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 ... -
Human Influences On Eastern Tropical Pacific Coral Communities and Coral Reefs
(2016)Coral reefs world-wide have been impacted by direct and indirect human activity and natural disturbances. This has led to the degradation and disappearance of many reef structures. On a basin-wide scale, the natural impact ... -
Indicator-based management recommendations for an artisanal bottom-longline fishery in Costa Rica, Central America
(2017)There is a growing need to strengthen the small-scale fishing sector with emerging governance methods that improve fishers’ threatened livelihoods. Therefore, this study’s aim was to develop management ... -
Intra- and inter-annual variation in a seagrass meadow on the Caribbean coast of Costa Rica: 2009-2015
(2018)Seagrass beds are an important ecosystem on the Caribbean coast of Costa Rica. At Cahuita National Park (CNP) a seagrass bed at Perezoso has been monitored continually since 1999 within the CARICOMP program. Thalassia ... -

(2015)Se describe la diversidad y composición de especies las playas de arena del Pacífico Sur de Costa Rica. En las playas de arena de la región, se colectó individuos de la infauna por medio de barrenos. Para la zona de entre ... -
Marine Biodiversity of Eastern Tropical Pacific Coral Reefs
(2017)The eastern tropical Pacific (ETP) is an isolated oceanic region exposed to extreme oceanographic conditions, including low salinity, low pH, high temperatures during El Niño, and low temperatures during La Niña and seasonal ... -
Molecular Assisted Identification Reveals Hidden Red Algae Diversity from the Burica Peninsula, Pacific Panama
(2017)The marine flora of Panama harbors a rich diversity of green, red and brown algae,and despite chronic understudy, it is reported as the second most diverse marine flora along thePacific Central American coast, with 174 ... -
Natural ocean acidification at Papagayo upwelling system (north Pacific Costa Rica): implications for reef development
(2018)Numerous experiments have shown that ocean acidification impedes coral calcification, but knowledge about in situ reef ecosystem response to ocean acidification is still scarce. Bahía Culebra, situated at the northern ... -
