Article
The Pourtalès Terrace is an exposed hard-bottom platform located south of the Florida Keys in 200–450 m depth with a diverse deep-sea coral ecosystem dominated by stylasterid hydrocorals, octocorals, and sponges that supports recreational and commercial fisheries. Portions of the Terrace have been designated as managed areas in the absence of detai...

Novel drug leads for malaria therapy are urgently needed because of the widespread emergence of resistance to all available drugs. Screening of the Harbor Branch enriched fraction library against the Plasmodium falciparum chloroquine-resistant strain (Dd2) followed by bioassay-guided fractionation led to the identification of two potent antiplasmod...

Although mesophotic coral reef ecosystems (MCEs) are widespread and diverse, they remain largely unexplored. The Caribbean MCEs are among the most studied in the world, but detailed information regarding Cuban MCEs is limited. In this study we present the first analyses of the ichthyofauna of the Cuban MCEs based on data from a research cruise in J...

Pulley Ridge is a limestone ridge that extends nearly 300 km along the southwestern Florida shelf in the eastern Gulf of Mexico. The southern terminus of Pulley Ridge supports a mesophotic coral ecosystem (MCE) at depths of 59–105 m and is the deepest known photosynthetic coral reef off the continental United States. The biodiversity consists of 95...

This photo album of selected macroalgae associated with Cuba’s mesophotic reefs resulted from a recent joint Cuba-U.S. expedition that was conducted from May 14 to June 13, 2017 to map and document the extent and health of MCEs along the entire coastline of Cuba. Total ship transit around the island covered ~2,778 km (~1,500 nmi). Forty-three Remot...

A joint Cuba-U.S. expedition was conducted May 14-June 12, 2017 to characterize for the first time the extent and health of mesophotic coral ecosystems (MCEs) along the entire coastline of Cuba. Remotely Operated Vehicle (ROV) dives at 36 sites confirmed the presence of MCE habitat along all coasts of Cuba. ROV dives covered 27 km, at depths of...

This annex to the U.S. Southeast chapter in “The State of Deep-Sea Coral and Sponge Ecosystems in the United States” provides a list of deep-sea coral taxa in the Phylum Cnidaria, Classes Anthozoa and Hydrozoa, known to occur in U.S. waters from Cape Hatteras to the Florida Keys. Deep-sea corals are defined as azooxanthellate, heterotrophic coral s...

Article
Red grouper (Epineph-elus morio) modify their habitat by excavating sediment to expose rocky pits, providing structurally complex habitat for many fish species. Surveys conducted with remotely operated vehicles from 2012 through 2015 were used to characterize fish assemblages associated with grouper pits at Pulley Ridge, a mesophotic coral ecosyste...
Article
The dormant phenotype acquired by Mycobacterium tuberculosis ( Mtb ) during infection poses a major challenge in disease treatment since these bacilli are tolerant to front-line drugs. Therefore, it is imperative to find novel compounds that effectively kill dormant bacteria. By screening 4,400 marine natural product samples against dual-fluorescen...
Article
Two new analogues of the potent antitumor compound leiodermatolide, which we call leiodermatolides B and C, have been isolated from specimens of a deep-water sponge of the genus Leiodermatium collected off Florida. The compounds were purified using standard chromatographic methods, and the structures defined through interpretation of the HRMS and 1...

A deep-water sponge of the genus Spongosorites has yielded a bis-indole alkaloid which we have named dragmacidin G. Dragmacidin G was first reported by us in the patent literature and has recently been reported by Hitora et al. from a sponge of the genus Lipastrotheya. Dragmacidin G is the first in this series of compounds to have a pyrazine ring l...

This study documents the distribution and habitat use of the golden crab (Chaceon fenneri), a commercially fished species, in relation to deep—sea coral/sponge ecosystems (DSCEs) at 200—900 m depths off eastern Florida. A total of 386 h of videotapes from 94 submersible and remotely operated vehicle (ROV) dives from 1999 to 2009, covering a total d...

Shelf-margin carbonate mounds in water depths of 116-135 m in the eastern Gulf of Mexico along the central west Florida shelf were investigated using swath bathymetry, side-scan sonar, sub-bottom imaging, rock dredging, and submersible dives. These enigmatic structures, known to fisherman as the”Sticky Grounds,” trend along slope, are 5 to 15 m in...

Background: The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of poaching activities harvesting tens of kg of coral per d...

Underwater video transect methods using small remotely operated vehicles (ROVs) and diver-operated video (DOV) are commonly used in benthic biodiversity assessments. Constraints posed by deeper waters have made surveys of the circalittoral zone (>30 m depth), a particularly challenging problem. Here we compare benthic diversity metrics and cluster...
Conference Paper
The Pourtalès Terrace is a curved, narrow triangular platform that parallels the Florida Keys for 213 km from southern Key Largo to west of Key West at depths of ~200‐450 m, and exhibits a wide variety of Neogene‐age features, including high‐relief ledges, mounds, sinkholes and bioherms. Because prominent features represent popular, long‐term fishi...
Conference Paper
The Miami Terrace is the primary seafloor feature of the southeastern margin of the Florida Peninsula north of the Florida Keys. It is a portion of a drowned carbonate platform, 120 km long and 22.2 km at its widest, that tapers both north and south, covers 740 km2, and spans a depth range of ~200-600 m. It lies directly beneath the Florida Current...
Article
In situ observations and photographs of the Caribbean roughshark, Oxynotus caribbaeus Cervigón, 1961, are reported for the first time from four widely separated localities around the tropical western Atlantic, including multiple records over an 8-yr period from a single locality off Roatán, Honduras. These records document an extension of the known...

The deep-sea (200-1000 m) seafloor off the southeastern U.S. has a variety of extensive deep-sea coral ecosystem (DSCE) habitats including: deep-water coral mounds; various hard-bottom habitats off Florida including the Miami Terrace, Pourtale`s Terrace, and deep-water canyons (Agassiz and Tortugas Valleys); and deep island slopes off western Baham...

Background: 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...
