This research investigates the distribution and population structure of crustaceans, endemic to anchialine systems in the tropical western Atlantic focusing on cave-dwelling shrimp from the family Barbouriidae. Taxonomic and molecular tools (genetic and genomic) are utilized to examine population dynamics and the presence of phenotypic hypervariation (PhyV) of the critically endangered species Barbouria cubensis (von Martens, 1872). The presence of PhyV and its geographic distribution is investigated among anchialine populations of B. cubensis from 34 sites on Abaco, Eleuthera, and San Salvador, Bahamas. Examination of 54 informative morphological characters revealed PhyV present in nearly 90% (n=463) of specimens with no …

The coral microbiome plays an integral role in coral health. Modification of the microbiome is thought to alter susceptibility to disease. Black Band Disease (BBD), is polymicrobial, mat forming, and affects reef building coral globally. Dominated by the cyanobacterium Roseofilum reptotaenium, it has been noted to increase in virulence with increasing temperatures, making BBD of particular concern in the face of climate change-induced warming seas. The active sulfur cycle of BBD makes dimethylsulfoniopropionate (DMSP), a widely available source of sulfur in the marine environment, of particular interest in the study of BBD. Traditional infection studies require field collection and …
