Introduction: Zooplankton is a major link between primary producers and the following trophic levels, and in coral reefs they represent an energy source for corals and involve complex assemblies integrating a wide variety of species form different functional groups. Objective: To define interannual chang...
Introduction: Zooplankton is a major link in coral reef food webs and a source of nutrients for corals. Demersal zooplankton in coral reefs makes diel migrations at night to avoid predation by fish and corals, increasing abundance and biomass at night. Objectives: To study the composition and variation o...
Introduction: El Niño 2015-2016 was considered one of the most severe worldwide, causing the third global event of coral bleaching. Previous high-intensity El Niño events (1982-83 and 1997-98) caused high coral mortalities and deterioration of coral reef structures along the Eastern Tropical Pacific, a...
Introduction: North Pacific Costa Rica is generally considered rich in marine habitats and species. However, some areas are subject to fishing pressures that could degrade ecosystems. The Gulf of Papagayo comprises protected and unprotected areas with various degrees of impact. Objectives: Our aim was to...

Introduction: Rehabilitation of hermatypic coral species that have declined in the Caribbean in recent decades is a priority. Production of sexual recruits is considered the best restoration method to aid affected populations. Objective: To gain knowledge of early life stages of Orbicella faveolata and t...
Abstract The sea anemone Condylactis gigantea is an ecologically important member of the benthic community in coral reefs of the tropical Atlantic, and displays two morphotypes with respect to the color in their tentacular tips: the green tip morphotype and the pink/purple tip morphotype. Although some m...
El mar Caribe de Guatemala forma parte del Sistema Arrecifal Mesoamericano (SAM), el cual alberga una alta diversidad de especies marinas. Dichas poblaciones son importantes para el bienestar de las comunidades humanas que habitan en la zona marino-costera de los países que conforman el SAM, y que depen...
ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history...
ABSTRACT The reef-building vermetid Petaloconchus varians occurs in the western Atlantic Ocean, from the Caribbean Sea to the southern coast of Brazil. The present study evaluated the abundance of P. varians on intertidal rocky shores in Ilha Grande Bay (Rio de Janeiro State), and characterized their ree...

ResumenEl primer avistamiento del pez león en el Parque Nacional "Cayos de San Felipe" en el 2009 podría amenazar la diversidad de sus ecosistemas marinos y la capacidad de brindar servicios. Para analizar la incidencia de la invasión del pez león en el área, se realizó un muestreo anual entre 2013...
