Un método para evaluar el enriquecimiento de metales en sedimentos marinos en Costa Rica
(Revista Biología Tropical 60 (2): 197-211, 2012-04-01)
A method to evaluate metal enrichment in marine sediments. In order to evaluate metal enrichment in sediments , a method is proposed and tested in Bahia Culebra and the Golfo de Nicoya, Costa Rica through the normalization ...
A carbonate platform associated with shallow cold methane seeps in Golfo Dulce, Pacific Costa Rica
Marine methane seeps are typically observed in cold, anoxic and organic-rich deep-sea environments, such as in the Black Sea, where methane emissions fuel the authigenic accretion of calcium carbonate structures via microbial ...
Feeding ecology of common demersal elasmobranch species in the Pacific coast of Costa Rica inferred from stable isotope and stomach content analyses
Knowledge of the feeding ecology and trophic interactions of marine species is essential to understanding food web dynamics and developing ecosystem-based management approaches. Given that many top predatory fishes have ...
A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part I: Eumuricea Verrill, 1869 revisited
Muricea is an amphi-American genus. Verrill proposed dividing the species from the Pacific Ocean into three genera and established the genus Eumuricea for five eastern Pacific species with tubular calyces. Eumuricea is ...
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 ...
Desarrollo costero y ambientes marino-costeros en Bahía Culebra, Guanacaste, Costa Rica
Coastal development and marine ecosystems in Culebra Bay, Guanacaste, Costa Rica
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 ...
Rapid bioerosion in a tropical upwelling coral reef
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 ...
Reef flattening effects on total richness and species responses in the Caribbean
1. There has been ongoing flattening of Caribbean coral reefs with the loss of habitat having severe implications for these systems. Complexity and its structural components are important to fish species richness and ...
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 ...
Seasonal changes of the microplankton community along a tropical estuary
Microplankton organisms are an important link in the transfer of matter and energy between the benthic–pelagic microbial food web and higher trophic levels in estuaries. Although tropical estuaries are among the most ...
