The distribution of Sphaerospora dicentrarchi Sitjà-Bobadilla et Alvarez-Pellitero, 1992 and S. testicularis Sitjà-Bobadilla et Alvarez-Pellitero, 1990, myxozoan parasites of European seabass Dicentrarchus labrax (L.), was investigated in different farming systems in Italy. In total, 1406 fish were examined. High S. dicentrarchi prevalence was observed in all the farming systems involved in thi...

Stomach contents from 449 schoolmaster snapper, Lutjanus apodus, from southwestern Puerto Rico were examined. Hierarchical cluster analysis identified two primary trophic groups: ::;70 mm FL and >70 mm FL. Small L. apodus (::;70 mm) fed almost exclusive]y on crustaceans (89% by weight; 95% by numbcr; 98% frequency of occurrence), particularly amphipods and crabs, By contrast, L. apodus greater ...

Like many marine species with meroplanktonic larvae, the Caribbean spiny lobster (Panulirus argus) has a postlarval stage that moves from the oceanic plankton to inshore nurseries only under specific environmental conditions (i.e., at night, in the surface water layer, on the flood tide, and during new moon), presumably to avoid predation or to enhance onshore transport. Using field and mesocos...

Availability of domain-specific datasets is an essential problem in object detection. Datasets inshore and offshore maritime vessels are no exception, with a limited number studies addressing vessel detection on such datasets. For that reason, we collected dataset consisting images taking into account different factors: background variation, atmospheric conditions, illumination, visible proport...

Tropical storms (cyclones, hurricanes, or typhoons) are the most severe form of mechanical disturbance of coral reefs. In 2005, severe tropical cyclone Ingrid crossed the far northern Great Barrier Reef, a region that had not been affected by a major disturbance for several decades, and where benthic data had been collected before the cyclone crossed. This storm provided a unique opportunity to...
