Marine biodiversity baseline for Área de Conservación Guanacaste, Costa Rica: published records
(2017)The diversity of tropical marine organisms has not been studied as intensively as the terrestrial biota worldwide. Additionally, marine biodiversity research in the tropics lags behind other regions. The 43,000 ha Sector ... -
Macrofauna bentónica de las playas de arena del Área de Conservación Osa, Puntarenas, Pacífico Sur de Costa Rica
(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 ... -
Feeding ecology of common demersal elasmobranch species in the Pacific coast of Costa Rica inferred from stable isotope and stomach content analyses
(2015)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 ... -
Effects of simulated overfishing on the succession of benthic algae and invertebrates in an upwelling-influenced coral reef of Pacific Costa Rica
(2015)Overfishing and nutrient enrichment are among the major local stressors to coral reefs worldwide, as they can alter the benthic reef community by promoting fast growing algae and bioeroders. The Northern coast of Pacific ... -
Hierarchical spatial patterns in Caribbean reef benthic assemblages
(2015)Aim: Coral assemblages on Caribbean reefs have largely been considered to be biogeographically homogeneous at a regional scale. We reassess this in three taxa (corals, sponges and octocorals) using three community attributes ... -
Evaluation of Extreme Waves Associated with Cyclonic Activity on San Andrés Island in the Caribbean Sea since 1900
(2015)San Andrés Island is one of the most important tourist destinations in the Caribbean Sea. The extreme waves associated with storms and hurricanes since 1900 were studied. A total of 17 important events was identified in ... -
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 ... -
Desarrollo costero y ambientes marino-costeros en Bahía Culebra, 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 ... -
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
