Coral-Excavating Sponge Cliona delitrix: Current Trends of Space Occupation on High Latitude Coral Reefs Hydrobiologia (2017)
The recent increase in abundance of coral-excavating sponges is a threat to the health of coral reefs. However, the distribution and growth of these sponges are poorly documented on high latitude reefs where corals live ...
Investigating the Spatial Distribution and Effects of Nearshore Topography on Acropora cervicornis Abundance in Southeast Florida PeerJ (2016)
Dense Acropora cervicornis aggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been ...
Siderastrea siderea Spawning and Oocyte Resorption at High Latitude Invertebrate Reproduction and Development (2016)
At high latitudes (>25°), sexual reproduction and the maintenance of coral populations can be impaired by marginal environmental conditions. However, little is known about sexual reproduction of many coral species at high latitude on the ...
Fecundity and Sexual Maturity of the Coral Siderastrea siderea at High Latitude Along the Florida Reef Tract, USA Invertebrate Biology (2016)
Siderastrea siderea is one of the most abundant corals at high latitude shallow sites along the Florida Reef Tract (25°–27°N). This species is able to tolerate wide seawater temperature fluctuations and sedimentation stress, but its ...
Effects of Excavating-Sponge Removal on Coral Growth Journal of the Marine Biological Association of the United Kingdom (2016)
Some excavating sponges are strong competitors for space on coral reefs, able to kill live coral tissue and to overgrow entire coral colonies. Stony corals with excavating sponges can die or become dislodged. To date ...
Percent Recent Mortality (PRM) of Stony Corals as an Ecological Indicator of Coral Reef Condition Ecological Indicators (2014)
The reef communities of the Florida coral reef tract play a major role in supporting the regional economy but are threatened by increased exploitation and environmental factors. Coral reef ecosystem services are vital to the ...
Possible Recovery of Acropora palmata (Scleractinia:Acroporidae) Within the Veracruz Reef System, Gulf of Mexico: A Survey of 24 Reefs to Assess the Benthic Communities Revista de Biologia Tropical (2014)
Recent evidence shows that Acropora palmata within the Veracruz Reef System, located in the southwestern Gulf of Mexico, may be recovering after the die off from the flooding of the Jamapa River and a dramatic ...
Determining the Extent and Characterizing Coral Reef Habitats of the Northern Latitudes of the Florida Reef Tract (Martin County) PLoS One (2013)
Climate change has recently been implicated in poleward shifts of many tropical species including corals; thus attention focused on higher-latitude coral communities is warranted to investigate possible range expansions and ecosystem shifts due to global ...
In Situ Coral Nurseries Serve as Genetic Repositories for Coral Reef Restoration After an Extreme Cold-Water Event Restoration Ecology (2012)
During an unusual cold-water event in January 2010, reefs along the Florida Reef Tract suffered extensive coral mortality, especially in shallow reef habitats in close proximity to shore and with connections to coastal bays. The ...
Small-Scale Mapping of Indeterminate Arborescent Acroporid Coral (Acropora cervicornis) Patches Coral Reefs (2012)
Western Atlantic populations of the staghorn coral Acropora cervicornis have drastically declined over the past few decades. Hence, interest in its ecology and spatial extent has increased. Acroporid corals with indeterminate arborescent growth like A.cervicornis ...
Caribbean Corals in Crisis: Record Thermal Stress, Bleaching, and Mortality in 2005 PLoS One (2010)
Background: The rising temperature of the world’s oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures ...
Elevated Sedimentation on Coral Reefs Adjacent to a Beach Nourishment Project Marine Pollution Bulletin (2010)
An increasingly common method to restore eroding beaches is nourishment, a process by which lost sand is replaced with terrestrial or offshore sediments to widen beaches. The southeastern Florida coastline contains shore-parallel coral reef communities ...
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, ...
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 ...
Reef Fish Assemblage Structure Affected by Small-Scale Spacing and Size Variations of Artificial Patch Reefs Journal of Experimental Marine Biology and Ecology (2005)
To examine how varying the distance between patch reefs affects reef fish assemblage structure, replicate concrete reef modules (∼ 1 m3 each) were deployed on sand bottom at 8 m depth off Ft. Lauderdale, Florida, ...
Growth and Survivorship of Stony Coral Meandrina meandrites and Montastrea cavernosa Transplants to an Artificial Reef Environment: A Work in Progress Nova Southeastern University (2003)
Reef Ball Deployment: In November of 2000, 160 concrete Reef BallTM modules (1.22m wide x 0.9m high) were deployed, at a depth of approximately 15 meters, between the Second and Third Reef tracts off Dania ...
Status of Coral Reefs of Little Cayman, Grand Cayman and Cayman Brac, British West Indies, in 1999 and 2000 (Part 1: Stony Corals and Algae) Atoll Research Bulletin (2003)
A benthic assessment of the isolated Cayman Islands was completed at 42 sites. Major changes in the reef community structure were documented by comparison with earlier studies. Acropora palmata and A. cervicornis, once abundant as ...
Artificial Substrate and Coral Reef Restoration: What Do We Need to Know to Know What We Need Bulletin of Marine Science (2001)
