Sea Turtles in the Dry Tortugas: Tracking Movements of Endangered Species in Florida's Coral-Reef Habitats

Kristen Hart and Keith Ludwig of the USGS Florida Integrated Science Center (FISC) participated in two research cruises in 2008 to study patterns of habitat use by endangered sea turtles in and around the National Park. Hart's research effort focuses on quantifying patterns of sea turtle habitat use, employing capture-recapture and satellite- and More...

Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources: Final Report, Synthesis and Assessment Product 4.4

The U.S. Environmental Protection Agency has released a report that can help reduce the potential impact of climate change on estuaries, forests, wetlands, coral reefs, and other sensitive ecosystems. The report identifies strategies to protect the environment as these changes occur. The report finds that climate change can increase the impact of More...

Trophic coupling and habitat connectivity among coral reef, mangrove, and seagrass fishes and benthic invertebrate communities of the Virgin Islands National Park (VIIS) and Coral Reef National Monument (VICR)

The connection between fish habitat utilization, prey use, and fish movement patterns is not known in relation to available invertebrate prey resources in off-reef sites. Developing a better understanding of the habitat use, diet, and resource needs of benthic communities and their interactions with mobile fish and invertebrates is an important More...

Coral Microbial Ecology: Coastal and Marine Geology Program

Coral microbial ecology is the study of the relationship of coral-associated microorganisms to each other, the coral host, and to their environment. Just as we humans have beneficial bacteria living on our skin and in our intestines, corals also have co-habitating non-pathogenic (not disease-causing) microbes. These microbes include bacteria, More...

Biological Communities and Geomorphology of Patch Reefs in Biscayne National Park, Florida, U.S.A.

This web resource is a map that shows all of the biological communities and geomorphology of patch reefs in Biscayne National Park, Florida. The map shows all of the patch reefs in Biscayne National Park that were surveyed in September 2003. Scientists investigated the relationships among physical, benthic, and fish variables in effort to help More...

Protocols for Monitoring with Digital Video and a SONAR-based Locating System (FISC)

Coral Reefs in the Caribbean and western Atlantic are deteriorating in response to hurricanes, coral diseases, anchor damage, sedimentation, and other stresses. USGS biologists at the Caribbean Field Station are documenting the current status of coral reefs and the effects of some of these stresses. The primary objective of this issue overview is More...

USGS DISCOVRE Expedition: Diversity, Systematics, and Connectivity of Vulnerable Reef Ecosystems

This 4-year multidisciplinary research program will focus on understanding the physical oceanography, biology, ecology, genetic connectivity, and trophodynamics of deep coral environments in the Gulf of Mexico (300-1000 m depths), both within natural and artificial (shipwreck) sites. A combination of traditional techniques (for example, More...

Community Structure and Adaptive Strategies of Fungi in Geothermal Soils

There are approximately 500,000 abandoned mines in the western US. Collectively, these mines pollute rivers, streams, and western reservoirs with millions of tons of metals annually that degrade aquatic habitat and water used by humans for drinking, recreation, and irrigation. However, there is great potential in decreasing or eliminating the flow More...
