New Records of Species of Macrovalvitrematidae Yamaguti, 1963 (Monogenea) from Puerto Rico Including One New Genus and Two New Species.

New records of Macrovalvitrematidae Yamaguti, 1963 are reported from Puerto Rico including Buccamagna archosarga n. gen., n.

Parasitism in Pterois volitans (Scorpaenidae) from coastal waters of Puerto Rico, the Cayman Islands, and the Bahamas.

Recently, Pterois volitans, a Pacific species of lionfish, invaded the Atlantic Ocean, likely via the aquarium trade. We examined for internal and external parasites 188 individuals from 8 municipalities of Puerto Rico collected during 2009-2012, 91 individuals from Little Cayman, Cayman Islands, collected during the summers of 2010 and 2011, and 47 individuals from Lee Stocking Island, Bahamas, collected during the summer of 2009. In total, 27 parasite taxa were found, including 3 previously reported species from lionfish, the digenean Lecithochirium floridense, the leech Trachelobdella lubrica, and an Excorallana sp.

New genus and species of fish blood fluke (Digenea: Aporocotylidae Odhner, 1912) from stoplight parrotfish, Sparisoma viride (Bonnaterre, 1788), (Labridae: Scarinae) in the Caribbean Sea.

Primisanguis caribbeanensis n. gen., n.

Caribbean corals in crisis: record thermal stress, bleaching, and mortality in 2005.

Background: The rising temperature of the world's oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.

Methodology/principal Findings: Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers' field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005.

Additional records of metazoan parasites from Caribbean marine mammals, including genetically identified anisakid nematodes.

Studies of marine mammal parasites in the Caribbean are scarce. An assessment for marine mammal endo- and ectoparasites from Puerto Rico and the Virgin Islands, but extending to other areas of the Caribbean, was conducted between 1989 and 1994. The present study complements the latter and enhances identification of anisakid nematodes using molecular markers.

Habitat and species differences in prevalence and intensity of Neobenedenia melleni (Monogenea: Capsalidae) on sympatric Caribbean surgeonfishes (Acanthuridae).

We quantified Neobenedenia melleni from the skin of Caribbean surgeonfishes (Acanthuridae) from June through October 2005 and 2007. Prevalence, or mean intensity of infection, or both, varied significantly among the 3 species, and among sites and between years for the most heavily infected species, blue tang (Acanthurus coeruleus). Among 6 sites sampled, no more than 12% of ocean surgeonfish (Acanthurus bahianus) were infected, compared with 10 to 100% of A.

Delayed population explosion of an introduced butterfly.

1. The causes of lagged population and geographical range expansions after species introductions are poorly understood, and there are relatively few detailed case studies. 2.

Helminth and arthropod parasites of the brown pelican, Pelecanus occidentalis, in Puerto Rico, with a compilation of all metazoan parasites reported from this host in the Western Hemisphere.

Seven species of helminths and six species of arthropods are reported from 23 of 40 brown pelicans, Pelecanus occidentalis, collected from various localities in Puerto Rico. Helminth parasites include three nematodes (Contracaecum multipapillatum, Contracaecum mexicanum, and Eustrongylides sp.), three trematodes (Galactosomum darbyi, Mesostephanus appendiculatoides, and Ribeiroia ondatrae), and one cestode (Tetrabothrium sulae).

Does lymphocystis occur in pacora, Plagioscion surinamensis (Sciaenidae), from Colombia?

A lymphocystis-like condition produced hemorrhagic lesions over the bodies of pacora Plagioscion surinamensis (Bleeker) (Perciformes: Sciaenidae) held in freshwater aquaculture in northern Colombia and increased their sensitivity to handling stress. This disease eliminated this fish from a project evaluating its aquaculture potential. Lymphocystis disease is assumed to be less damaging to the host.

Thermal influences on oviposition in the montane butterfly Euphydryas gillettii.

Euphydryas gillettii in a montane meadow in Wyoming oviposits in clusters on the highest large leaves of its larval host, the shrub Lonicera involucrata. Egg masses are found on the underside of leaves which predominantly face the southeast and thereby intercept morning sun. Measurements of leaf temperatures show that, during the cool, clear mornings, these leaves are warmer than leaves of the opposite orientation.
