Rapid bioerosion in a tropical upwelling coral reef
(2018)
Coral reefs persist in an accretion-erosion balance, which is critical for understanding the natural variability of sediment production, reef accretion, and their effects on the carbonate budget. Bioerosion (i.e. biodegradation ...
Importance of differentiating Orbicella reefs from gorgonian plains for ecological assessments of Caribbean reefs
(2015)
Region-wide assessments of coral cover typically rely on meta-analyses of small-scale ecological studies which have combined different coral reef habitats. This is particularly problematic on forereefs where at least 2 ...
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 ...
Desarrollo costero y ambientes marino-costeros en Bahía Culebra, Guanacaste, Costa Rica
Coastal development and marine ecosystems in Culebra Bay, Guanacaste, Costa Rica
(2018-04-01)
Bahía Culebra ha experimentado un proceso acelerado de desarrollo costero desde la implementación del proyecto Polo Turístico Golfo de Papagayo. Este trabajo analiza el cambio temporal en el estado de salud sus ecosistemas ...
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, ...
Los accidentes acuáticos alrededor de nuestras costas y su relación con el estado del mar y de la atmósfera
(2017)
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 ...
Fixed-Nitrogen Loss Associated with Sinking Zooplankton Carcasses in a Coastal Oxygen Minimum Zone (Golfo Dulce, Costa Rica)
(2017)
Oxygen minimum zones (OMZs) in the ocean are of key importance for pelagic fixed-nitrogen loss (N-loss) through microbial denitrification and anaerobic ammonium oxidation (anammox). Recent studies document that zooplankton ...
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 ...
New records of gelatinous zooplankton from an oceanic island in the Eastern Tropical Pacific
(2017)
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 ...
