Mapping Coral Reef Habitats In Southeast Florida Using A Combined Technique Approach, Brian K. Walker, Bernhard Riegl, Richard E. Dodge
Mapping Coral Reef Habitats In Southeast Florida Using A Combined Technique Approach, Brian K. Walker, Bernhard Riegl, Richard E. Dodge

To create maps of nearshore benthic habitats of Broward County, Florida, from 0 to 35 m depth, we combined laser bathymetry, acoustic ground discrimination, subbottom profiling, and aerial photography data in a geographic information system (GIS). A mosaic of interpolated, sun-shaded, laser bathymetry data served as the foundation upon which acoustic ground discrimination, limited subbottom profiling and aerial photography, and groundtruthing data aided in interpretation of habitats. Mapping criteria similar to NOAA biogeographic Caribbean mapping were used to allow for a comparable output. Expert-driven visual interpretation outlined geomorphological features at a scale of 1 : 6000 with a minimum mapping …
A Tale Of Germs, Storms, And Bombs: Geomorphology And Coral Assemblage Structure At Vieques (Puerto Rico) Compared To St. Croix (U.S. Virgin Islands), Bernhard Riegl, Ryan P. Moyer, Brian K. Walker, Kevin E. Kohler, David S. Gilliam, Richard E. Dodge

The former U.S. Navy range at Vieques Island (Puerto Rico, United States) is now the largest national wildlife refuge in the Caribbean. We investigated the geomorphology and benthic assemblage structure to understand the status of the coral reefs. Coral assemblages were quantified at 24 sites at Vieques and at 6 sites at St. Croix, U.S. Virgin Islands. These sites were chosen to represent the major zones of reef geomorphology. Sites consisted of two or three 21-m-long photo-quadrate belt transects. The results revealed surprisingly little differentiation in the coral assemblages within and between reefs of comparable geomorphological and oceanographic setting at …
Comparison Of Bacterial Diversity Within The Coral Reef Sponge, Axinella Corrugata, And The Encrusting Coral Erythropodium Caribaeorum, Jose V. Lopez, L. K. Ranzer, A. Ledger, B. Schoch, A. Duckworth, P. J. Mccarthy, R. G. Kerr

We compared the Caribbean reef sponge, Axinella corrugata, with the Caribbean reef coral, Erythropodium caribaeorum for differences in their resident microbial communities. This cursory survey of bacterial diversity applied 16S rRNA gene sequences. Over 100 culture-independent sequences were generated from five different Axinella 16S rRNA libraries, and compared with 69 cultured isolates. The cultureindependent 16S rDNA clones displayed a higher diversity of Proteobacteria, including “uncultured” or “unknown” representatives from the Deltaproteobacteria. Arcobacterium, and Cyanobacteria were also found. We have also confirmed that Axinella sponges appeared to host specific microbial symbionts, similar to the previously identified clones termed “OSO” …
Scleractinian Coral Recruitment To Reefs Physically Damaged By Ship Groundings, E. T. Rubin, Alison L. Moulding, Jose V. Lopez, David S. Gilliam, V. N. Kosmynin, Richard E. Dodge
Scleractinian Coral Recruitment To Reefs Physically Damaged By Ship Groundings, E. T. Rubin, Alison L. Moulding, Jose V. Lopez, David S. Gilliam, V. N. Kosmynin, Richard E. Dodge

The southeast Florida reef system faces a number of stress factors, among which ship groundings are one of the most physically damaging. Portions of the Florida reef tract located near Port Everglades, Broward County, Florida, USA have been damaged by ship groundings. In 2004, physical damage of more than 30,000 m2 was caused by the groundings of two large cargo ships, the MV Eastwind and MV Federal Pescadores. The present study was designed to measure differences of scleractinian coral recruitment patterns (recruit diversity and richness) and rates to these injured sites in comparison to undamaged reef sites. Coral …

In June 2003, fisheries research was conducted in the Windward Passage using a chartered commercial pelagic longline vessel (Rice and Snodgrass 2003). This paper describes the habitat use by an escolar in this location tagged with a pop-up satellite archival tag (PSAT) that remained attached to the fish for 14 d. Data recovered from the PSAT were used to directly document diel vertical migration and ambient temperature range for the first time in a mesopelagic teleost.

Recent review of deep-sea fishes captured deeper than 200m off greater New England, from the Scotian Shelf at 44°N to the southern New England Shelf at about 38°N, documented 591 species. Subsequent trawling activity and reviews of deep-sea taxa occurring in the area have revealed that an additional 40 species in habit the deep sea off New England. Thirty-two of these new records were captured in the course of 44 bottom trawls and 94 mid-water trawls over or in the proximity of Bear Seamount (39°55'N, 67°30'W). Five of the 40 species have been described as new to science, at least …

Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously implicated in OA production. Analysis of 16S rRNA libraries reveals that Roseobacter are the most abundant bacteria associated with OA producing dinoflagellates of the genus Prorocentrum and are not found in association with non-toxic dinoflagellates. While some polyketide synthase (PKS) genes form a highly supported Prorocentrum clade, most appear to be bacterial, but unrelated to Roseobacter or Alpha-Proteobacterial PKSs or those derived from other Alveolates …
