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 ...
Indicator-based management recommendations for an artisanal bottom-longline fishery in Costa Rica, Central America
Recomendaciones de manejo basadas en indicadores para la pesca artesanal con líneas de fondo en Costa Rica, Centroamérica
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 ...
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 ...
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 ...
Simulated overfishing and natural eutrophication promote the relative success of a non-indigenous ascidian in coral reefs at the Pacific coast of Costa Rica
Colonial ascidians of the genus Didemnum are common fouling organisms and are typically associated with degraded ecosystems and anthropogenic structures installed in the sea. In this study, however, the non-indigenous ...
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 ...
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 ...
Cambios en la cobertura de manglares en Bahía Culebra, Pacífico Norte de Costa Rica (1945-2010)
Changes in mangrove coverage in Culebra Bay, North Pacific of Costa Rica (1945-2010)
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 ...
Natural ocean acidification at Papagayo upwelling system (north Pacific Costa Rica): implications for reef development
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 ...
Abundance patterns (1984-1987 / 1994-1998) of polychaete worms (Annelida) from an estuarine tidal flat, Pacific, Costa Rica
The objectives of this report are to provide an updated list of the annelid polychaete worm species found at a tropical estuarine intertidal flat, describe long term oscillations of 11 of the species, and the impact of red ...
