This research is part of a grant funded by the NOAA National Centers for Coastal Ocean Science award NA11NOS4780045: “Connectivity of the Pulley Ridge - South Florida Coral Reef Ecosystem”. The University of Miami ship R/V Walton Smith was used along with the University of North Carolina at Wilmington (UNCW) Super Phantom ROV and the National Marine Sanctuary Foundation (NMSF) Mohawk ROV. The cruises were a collaboration of the University of Miami, HBOI-CIOERT, NOAA Fisheries, and the UNCW-CIOERT Undersea Vehicles Program.

Marine fisheries scientists, user groups, and resource managers in the southeastern Atlantic states have determined that there is need for accurate information on the location and extent of hard-bottom habitat, which is of importance to the maintenance of reef-fish stocks. Reef fish have declined to such low levels that reproductive stocks are often inadequate to maintain current populations, and some fisheries stocks may be approaching a state of collapse.

Show moreMarine fisheries scientists, user groups, and resource managers in the southeastern Atlantic states have determined that there is need for accurate information on the location and extent of hard-bottom habitat, which is of importance to the maintenance of reef-fish stocks. Reef fish have declined to such low levels that reproductive stocks are often inadequate to maintain current populations, and some fisheries stocks may be approaching a state of collapse. In order to meet this need for information, a Bottom Mapping Work Group was formed in 1985 by the SEAMAP management committee. The work group developed a plan for establishing a bottom-mapping database using historical information obtained from surveys of the study area, and a study was subsequently initiated to describe and characterize hard-bottom resources in the South Atlantic Bight. . The initial segment of the study was conducted by scientists in South Carolina and Georgia (Van Dolah et al., 1994), and the study was continued by scientists in North Carolina (Moser et al., 1995). A total of 23,960 records with information on location and type of bottom were compiled during the first two segments of the study. The SEAMAP Bottom-Mapping Study was initiated by Florida in 1994. The Florida study group has 1) expanded the list of hard-bottom-obligate fishes to 264 taxa, 2) developed a protocol for using specimen-collection-based information to acquire evidence of bottom type, and 3) developed a protocol for incorporating areal data into the database so that the area-data records are equivalent to those of the point and line-segment records incorporated into the database during the first two segments of the study. The Florida group has incorporated an additional 20,787 records from 37 sources with determinations of bottom type into the database. Of these records, 900 are derived from 9 areal databases, primarily from surveys that used side-scan sonar, and an additional secondary data table (Appendix 4) that summarizes those records has been added to the database. Approximately 37% of the grid cells in the Florida study area contain some data on bottom type, and the database now totals 44,747 records.

The purpose of this research cruise was to discover and characterize, for the first time, the extent of mesophotic reefs along the entire coastline of Cuba, and to compare the health and connectivity (physical, genetic and ecological) among both mesophotic and previously well-characterized shallow reef systems in Cuba, the southeastern United States, and Gulf of Mexico (in particular, the FGBNMS and FKNMS). Moreover, the project will directly address a recommendation in the Report from...

Show moreThe continental margin off the northeastern United States (NEUS) contains numerous, topographically complex features that increase habitat heterogeneity across the region. However, the majority of these rugged features have never been surveyed, particularly using direct observations. During summer 2013, 31 Remotely-Operated Vehicle (ROV) dives were conducted from 494 to 3271 m depth across a variety of seafloor features to document communities and to infer geological processes that produced such features. The ROV surveyed six broad-scale habitat features, consisting of shelf-breaching canyons, slope-sourced canyons, inter-canyon areas, open-slope/landslide-scar areas, hydrocarbon seeps, and Mytilus Seamount. Four previously unknown chemosynthetic communities dominated by Bathymodiolus mussels were documented. Seafloor methane hydrate was observed at two seep sites. Multivariate analyses indicated that depth and broad-scale habitat significantly influenced megafaunal coral (58 taxa), demersal fish (69 taxa), and decapod crustacean (34 taxa) assemblages. Species richness of fishes and crustaceans significantly declined with depth, while there was no relationship between coral richness and depth. Turnover in assemblage structure occurred on the middle to lower slope at the approximate boundaries of water masses found previously in the region. Coral species richness was also an important variable explaining variation in fish and crustacean assemblages. Coral diversity may serve as an indicator of habitat suitability and variation in available niche diversity for these taxonomic groups. Our surveys added 24 putative coral species and three fishes to the known regional fauna, including the black coral Telopathes magna, the octocoral Metallogorgia melanotrichos and the fishes Gaidropsarus argentatus, Guttigadus latifrons, and Lepidion guentheri. Marine litter was observed on 81% of the dives, with at least 12 coral colonies entangled in debris. While initial exploration revealed the NEUS region to be both geologically dynamic and biologically diverse, further research into the abiotic conditions and the biotic interactions that influence species abundance and distribution is needed.

To improve understanding of the phylogenetic relationships within Demospongiae, we sequenced and analyzed seven nuclear housekeeping genes involved in a variety of cellular functions from a diverse group of sponges.

Show moreBackground: Demosponges are challenging for phylogenetic systematics because of their plastic and relatively simple morphologies and many deep divergences between major clades. To improve understanding of the phylogenetic relationships within Demospongiae, we sequenced and analyzed seven nuclear housekeeping genes involved in a variety of cellular functions from a diverse group of sponges. Methodology/Principal Findings: We generated data from each of the four sponge classes (i.e., Calcarea, Demospongiae, Hexactinellida, and Homoscleromorpha), but focused on family-level relationships within demosponges. With data for 21 newly sampled families, our Maximum Likelihood and Bayesian-based approaches recovered previously phylogenetically defined taxa: Keratosap, Myxospongiaep, Spongillidap, Haploscleromorphap (the marine haplosclerids) and Democlaviap. We found conflicting results concerning the relationships of Keratosap and Myxospongiaep to the remaining demosponges, but our results strongly supported a clade of Haploscleromorphap+Spongillidap+Democlaviap. In contrast to hypotheses based on mitochondrial genome and ribosomal data, nuclear housekeeping gene data suggested that freshwater sponges (Spongillidap) are sister to Haploscleromorphap rather than part of Democlaviap. Within Keratosap, we found equivocal results as to the monophyly of Dictyoceratida. Within Myxospongiaep, Chondrosida and Verongida were monophyletic. A wellsupported clade within Democlaviap, Tetractinellidap, composed of all sampled members of Astrophorina and Spirophorina (including the only lithistid in our analysis), was consistently revealed as the sister group to all other members of Democlaviap. Within Tetractinellidap, we did not recover monophyletic Astrophorina or Spirophorina. Our results also reaffirmed the monophyly of order Poecilosclerida (excluding Desmacellidae and Raspailiidae), and polyphyly of Hadromerida and Halichondrida. Conclusions/Significance: These results, using an independent nuclear gene set, confirmed many hypotheses based on ribosomal and/or mitochondrial genes, and they also identified clades with low statistical support or clades that conflicted with traditional morphological classification. Our results will serve as a basis for future exploration of these outstanding questions using more taxon- and gene-rich datasets.
