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 ... -
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 ... -

(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 ... -
Analysis of the Latin American west coast rainfall predictability using an ENSO index
(2015)El objetivo de este estudio es determinar la probabilidad de ocurrencia de estaciones lluviosas o secas a lo largo de la costa oeste de Centro y Sudamérica, mediante la construcción de perfiles latitudinales para la ... -
Dynamics in benthic community composition and influencing factors in an upwelling-exposed coral reef on the Pacific coast of Costa Rica
(2015-11-24)Seasonal upwelling at the northern Pacific coast of Costa Rica offers the opportunity to investigate the effects of pronounced changes in key water parameters on fine-scale dynamics of local coral reef communities. This ... -
A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part I: Eumuricea Verrill, 1869 revisited
(2015)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 ... -
A carbonate platform associated with shallow cold methane seeps in Golfo Dulce, Pacific Costa Rica
(2015)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 ... -
Abundance patterns (1984-1987 / 1994-1998) of polychaete worms (Annelida) from an estuarine tidal flat, Pacific, Costa Rica
(2015-12)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 ... -
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. ... -
Systematics and biogeography of Pleurobranchus Cuvier, 1804, sea slugs (Heterobranchia: Nudipleura: Pleurobranchidae)
(2015)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 ... -
Occurrence of the tripodfish Bathypterois ventralis (Aulopiformes: Ipnopidae) in the Pacific coast of Costa Rica
(2015-05)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 ... -
Nueva especie del género Urobatis (Myliobatiformes: Urotrygonidae) del Pacífico oriental tropical
(2015-06)Una nueva especie de raya redonda con espina, Urobatis pardalis sp. nov., es descrita a partir de material recolectado en las costas del Pacífico de Costa Rica. Esta nueva especie difiere de sus congéneres por el patrón ... -
Upwelling Increases Net Primary Production of Corals and Reef-Wide Gross Primary Production Along the Pacific Coast of Costa Rica
(2015-12-23)Photosynthetic production is a key ecosystem service provided by tropical coral reefs, but knowledge about the contribution of corals and other reef-associated organisms and the controlling environmental factors is scarce. ... -
A new alcyonacean octocoral (Cnidaria, Anthozoa, Octocorallia) from Chilean fjords
(2015-02-17)A new species, Swiftia comauensis, is described from Chile. It occurs in shallow waters from 18 to 59 m in the Patagonian fjord region and seems to be endemic to the northern part of the region. The species is characterized ... -
Effects of Seasonal Upwelling on Inorganic and Organic Matter Dynamics in the Water Column of Eastern Pacific Coral Reefs
(2015-11)The Gulf of Papagayo at the northern Pacific coast of Costa Rica experiences pronounced seasonal changes in water parameters caused by wind-driven coastal upwelling. While remote sensing and open water sampling already ... -
Seasonal changes of the microplankton community along a tropical estuary
(2015-11)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 ... -
Productividad primaria en el Humedal Nacional Térraba-Sierpe, Costa Rica
(2015)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 ... -
