Previous research evaluating hydrocarbon toxicity to corals and coral reefs has generally focused on community-level effects, and results often are not comparable between studies because of variability in hydrocarbon exposure characterization and evaluation of coral ...
Forecasting the Success of Invasive Marine Species; Lessons Learned from Purposeful Reef Fish Releases in the Hawaiian Islands Fisheries Research (2016)
Eleven grouper, snapper, and emperor fish species were intentionally released in the Hawaiian Islands spanning the years 1955–1961 to produce new fisheries. Within 15 years, three of the introduced species established self-sustaining populations and eight ...
Measuring Bahamian Lionfish Impacts to Marine Ecological Services Using Habitat Equivalency Analysis Marine Biology (2015)
Marine ecological services provide goods, amenities, food resources, and economic benefits to millions of people globally. The loss of these services, attributed to the infiltration of marine invasive species such as the Indo-Pacific lionfish (Pterois ...
Growth Rates of Florida Corals from 1937 to 1996 and Their Response to Climate Change Nature Communications (2011)
Ocean acidification causes declines in calcification rates of corals because of decreasing aragonite saturation states (Ωarag). Recent evidence also indicates that increasing sea surface temperatures may have already reduced growth and calcification rates because of ...
The 13C Suess Effect in Scleractinian Corals Mirror Changes in the Anthropogenic CO2 Inventory of the Surface Oceans Geophysical Research Letters (2010)
New δ13C data are presented from 10 coral skeletons collected from Florida and elsewhere in the Caribbean (Dominica, Dominican Republic, Puerto Rico, and Belize). These corals range from 96 to 200 years in age and ...
Coral Reefs: Threats and Conservation in an Era of Global Change Annals of the New York Academy of Sciences (2009)
Coral reefs are iconic, threatened ecosystems that have been in existence for ∼500 million years, yet their continued ecological persistence seems doubtful at present. Anthropogenic modification of chemical and physical atmospheric dynamics that cause coral ...
Mapping Coral Reef Habitats in Southeast Florida Using a Combined Technique Approach Journal of Coastal Research (2008)
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 ...
A Tale of Germs, Storms, and Bombs: Geomorphology and Coral Assemblage Structure at Vieques (Puerto Rico) Compared to St. Croix (U.S. Virgin Islands) Journal of Coastal Research (2008)
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 ...
Scleractinian Coral Recruitment to Reefs Physically Damaged by Ship Groundings Proceedings of the 11th International Coral Reef Symposium, Ft. Lauderdale, Florida, 7-11 July 2008 (2008)
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, ...
Geomorphology of the Southeast Florida Continental Reef Tract (Miami-Dade, Broward, and Palm Beach Counties, USA) Coral Reefs (2007)
This paper describes the geomorphology of the northern, relict, portion of the Florida reef tract that extends along the southeast Florida (USA) continental coast northward to latitude N26° 43.1′. The descriptions are based on high-resolution ...
Cellular Reactions to Sedimentation and Temperature Stress in the Caribbean Coral Montastraea cavernosa Journal of Invertebrate Pathology (2007)
We present evidence of cellular responses to increased sedimentation and temperature in Montastraea cavernosa collected off Broward County, Florida. We sampled corals from six different sites approximately, 500–1000 m off shore, 10–15 m depth. Six ...
Assessing the Accuracy of Acoustic Seabed Classification for Mapping Coral Reef Environments in South Florida (Broward County, USA) Revista de Biología Tropical (2005)
