Marine Tardigrades From South Carolina, Usa, Paul J. Bartels, Lilvia J. Bradbury, Diane R. Nelson
Journal of the South Carolina Academy of Science
Until now, there have been only three studies of marine tardigrades from South Carolina, USA. The Fall 2015 invertebrate zoology class from Warren Wilson College collected four sediment samples from Huntington Beach State Park: shallow beach sand, deep beach sand, shallow salt marsh sediment, and deep salt marsh sediment. No tardigrades were found in the salt marsh, but two species were found in the beach samples. Batillipes pennaki Marcus, 1946 was found in shallow and deep beach sand, and three specimens of a potentially new species of Stygarctus Schulz, 1951 were found in the deep beach sand at groundwater level. …

Bleaching of corals and other organisms with symbiotic zooxanthellae is a worldwide phenomenon with increasing importance due to global warming scenarios. Bleaching has been historically related to changes in the environment, especially water temperature increase, that stress corals and provoke the release of zooxanthellae. The discovery of Vibrio shilonii, a bacterium causing bleaching under thermal stress in corals of the Mediterranean Sea has changed our thinking about the cause (or explanation) for bleaching of corals worldwide. During this study, we evaluated the effect of a proline rich toxin, extracted from Vibrio shilonii, on zooxanthellae obtained from: Oculina patagonica from the …

Aspergillosis Of Pseudopterogorgia Americana: Increased Host Range Of Aspergillus Sydowii From The Wider Caribbean, Garriet W. Smith

Reports of gorgonian diseases have been increasing in the past few years,but, with the exception of Gorgonia spp., the etiological agents responsible are generally unknown. In the summer of 1999, populations of Pseudopterogorgia americana were observed with lesions and galls, somewhat similar to Aspergillus sydowii infections on Gorgonia ventalina, in Bermuda. Surveys of three sites were made, repeated the following two years, and compared with sites in the Bahamas. Microscopic observations of affected tissue and subsequent pure culture studies indicated the pathogen was also A. sydowii. Over half of the colonies at the Bahamas site were affected, but …
