The Class Monogenea van Beneden, 1858 comprises a diverse group of platyhelminthes parasitic primarily on the external surfaces and gills of marine and freshwater fishes. The family Macrovalvitrematidae Yamaguti, 1963 ...

Recurrent blooms of the potentially ichthyotoxic dinoflagellate Cochlodinium polykrikoides were observed since 1958 at Bahía Fosforescente, a bioluminescent bay in southwestern Puerto Rico. Despite its potential deleterious ...

Clear coral reefs waters are highly transparent to ultraviolet radiation (UVR) and therefore, reef organisms should be adapted to tolerate present levels of UVR. However, UVR can severely damage coral tissues and overall ...

The northern quahog, Mercenaria mercenaria was accidentally introduced to Puerto Rico in the early decades of the 20th century. Since then, a small-scale market has been established along the northeast coast of the island. ...

Since the mid-1980s, two Indo-Pacific lionfishes, Pterois volitans and P. miles, have established a significant presence in the Western North Atlantic, including the Caribbean Sea and the Gulf of Mexico. The first documented ...

The relationship between the distribution, abundance, and movement of fishes to the abundance and arrangement of habitats constitutes a fundamental basis for ecosystem-based management. Defining nursery areas, essential ...

A detailed 5 year study of algal community structure at 8 coral reefs distributed across the insular shelf at La Parguera, Puerto Rico was undertaken between 2003 and 2007. Significant temporal variation in species cover ...

Fragmentation and local dispersion of hurricane-generated fragments have been considered an important feature in the life history, population dynamics and genetic structure of the elkhorn coral Acropora palmata. The ...

Atmospheric transport of aerosols from desert regions of Africa supply nutrients, such as iron, to oligotrophic oceanic waters. Phytoplanktonic organisms in surface waters use bio-available Fe, increasing their rate of ...

Natural populations of many marine invertebrates are under pressure by fisheries due to the increasing demand and unit prices leading to overexploitation. I examined the genetic variation of two marine invertebrates: the ...
