Caribbean-Wide, Long-Term Study of Seagrass Beds Reveals Local Variations, Shifts in Community Structure and Occasional Collapse
The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites (mostly Thalassia testudinum-dominated beds in reef systems) across the Wider Caribbean twice a year over the period ...
Global Human Footprint on the Linkage between Biodiversity and Ecosystem Functioning in Reef Fishes
Difficulties in scaling up theoretical and experimental results have raised controversy over the consequences of biodiversity loss for the functioning of natural ecosystems. Using a global survey of reef fish assemblages, ...
New record of Stellamedusa ventana Raskoff & Matsumoto, 2004 in the Eastern Tropical Pacific
Three specimens of the rare scyphozoan Stellamedusa ventana Raskoff & Matsumoto, 2004 were collected during a vertical plankton tow on April 2013 in a shallow bay on the Eastern Tropical Pacific that was sampled eight times ...
New record of the starfish Ophidiaster ludwigi (Echinodermata: Asteroidea) from the Paciﬁc of Mexico and Costa Rica
Ophidiaster ludwigi had been reported only from Panama and Peru. Here we add record of the genus and species for Mexico and Costa Rica; and, first time its bathymetric distribution (0-156 m)
Ecological assessments of the coral reef communities in the Eastern Caribbean and the effects of herbivory in influencing coral juvenile density and algal cover
Caribbean reefs have been unevenly surveyed, with many areas lacking baseline data. In this study, the current status of Orbicella reefs, a structurally complex forereef habitat, was quantified in an understudied region, ...
Los accidentes acuáticos alrededor de nuestras costas y su relación con el estado del mar y de la atmósfera
Se hace una revisión de los principales fenómenos océano-atmosféricos que pueden producir accidentes acuáticos en nuestras costas, describiendo sus características, propagación y orígenes. Se recopilaron varios casos ...
Fixed-Nitrogen Loss Associated with Sinking Zooplankton Carcasses in a Coastal Oxygen Minimum Zone (Golfo Dulce, Costa Rica)
Oxygen minimum zones (OMZs) in the ocean are of key importance for pelagic fixed-nitrogen loss (N-loss) through microbial denitrification and anaerobic ammonium oxidation (anammox). Recent studies document that zooplankton ...
Gastropods and bivalves taken as by-catch in the deep-water shrimp trawl-fishery along the Pacific coast of Costa Rica, Central America
Deep-water habitats are among the least studied but most vulnerable environments. By-catch data from deep-water fisheries in Latin America are limited, and detailed reports on associated molluscs are scarce. This study ...
New records of gelatinous zooplankton from an oceanic island in the Eastern Tropical Pacific
Gelatinous zooplankton are an abundant and diverse group of animals in the pelagic environment. However, knowledge of species diversity and spatial distributions, as well as their ecological role, is scarce. We present ...
Seagrass morphometrics at species level in Moreton Bay, Australia from 2012 to 2013
Seagrass above, below and total biomass, density and leaf area, length and width were quantified at a species level for 122 sites over three sampling periods in Moreton Bay, Australia. Core samples were collected in two ...
