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 ...
Polychaetes associated with decaying wood in Térraba mangrove, South Pacific, Costa Rica
Poliquetos asociados a madera en descomposición en el manglar de Térraba, Pacífico Sur, Costa Rica
The present study shows spatial patterns in the faunal assemblage of decaying wood and sediments, with emphasis on the polychaetes. The survey was executed across a salinity gradient in a tropical mangrove estuary of Costa ...
Evaluation of Extreme Waves Associated with Cyclonic Activity on San Andrés Island in the Caribbean Sea since 1900
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 ...
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 ...

One year weekly dynamics of limnological conditions and phytoplankton in Lake Bonilla, Costa Rica
The detailed response of tropical lake phytoplankton to weather variations has been little studied, but it seems that composition varies in response to rain and wind variability over the course of the year. In order to ...
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 ...
Importance of differentiating Orbicella reefs from gorgonian plains for ecological assessments of Caribbean reefs
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 ...
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 ...
Seasonal phenology of Sargassum liebmannii J. Agardh (Fucales, Heterokontophyta) in an upwelling area of the Eastern Tropical Pacific
Seasonal changes in growth, biomass, abundance and reproduction of brown algae have been reported from subtropical and temperate regions, but there are very few reports from tropical regions, and none from the Eastern ...
