A list of all known polychaete species reported in the primary literature is presented for the Caribbean Sea. The most spe-cies-rich polychaete faunas are those of Cuba in the North Caribbean ecoregion and Trinidad-Tobago and Colombia in theSouth Caribbean ecoregion while the ecoregion with the greatest number of species is the Greater Antilles. While part ofthe explanation for these higher diversity areas may be due to collection effort, these areas may also be higher in speciesnumber as a result of being ecotones between the Gulf of Mexico in the north and the northern South American region tothe south. The most species-rich families are the Syllidae, Eunicidae, Nereididae, Polynoidae, Sabellidae, Serpulidae, Ter-ebellidae, and Spionidae. A brief discussion of the history of polychaete research identified many of the more importantworkers in the characterization of the polychaete fauna of the region. An analysis of the species-record accumulation curvefor polychaetes indicated that this fauna has not yet been fully characterized. One portion of the polychaete fauna identified as being especially poorly known is that from the deep-water areas of the Caribbean.

Paired End Sequencing

As a first step to establish the genetic structure of the sea urchin Echinometra lucunter lucunter throughout the Caribbean Sea, 26 microsatellite loci were isolated using Illumina paired-end sequencing, Next Generation Sequencing (NGS). We successfully optimized 17 loci for genotyping and the variation tested for 23 individuals from the Caribbean Sea and Tropical Eastern Atlantic Ocean. The allele number per locus (Na) ranged from four to 24, the observed heterozygosity (Ho) from 0.682 to 1, and the expected heterozygosity (He) from 0.609 to 0.9304. We detected no linkage disequilibrium between pairs of loci. These microsatellites will be used for the first time to detect the influence of marine barriers to genetic flow in the sea urchin E. lucunter lucunter throughout the Caribbean Sea. These new validated markers will be essential for current conservation and connectivity studies across the Caribbean Sea and the Atlantic Ocean.

Fuscol and the related fuscosides are diterpenes isolated from the Caribbean gorgonian Eunicea fusca, which exhibit potent anti-inflammatory activity with a selective action against leukotriene production in murine models. This report describes the isolation and characterization of the diterpene cyclase product leading to these natural products. The cyclase product has been assigned the trivial name eunicene A and was identified through a radioactivity-guided isolation. Additional biosynthetic experiments conducted by incubating a cell-free extract of E. fusca with 3H-labelled metabolites confirmed the involvement of this unsaturated hydrocarbon in the production of fuscol and fuscosides.
