The South Florida Fish and Invertebrate Assessment Network (FIAN) is a monitoring project within the Comprehensive Everglades Restoration Plan (CERP). It is an element of the Southern Estuaries module of the Monitoring and Assessment Plan (MAP).The FIAN is designed to support the four broad objectives of MAP: (1) to establish a pre-CERP reference state, including variability, for each of the performance measures; (2) to determine the status and trends in the performance measures; (3) to detect unexpected responses of the ecosystem to changes in stressors resulting from CERP activities; and (4) to support scientific investigations designed to increase ecosystem understanding, cause-and-effect, and interpretation...
Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally threatened freshwater mussel species endemic to the Suwannee River basin in Georgia and Florida. We also assessed the influence of survey effort on detection of M. walkeri during field surveys. All current (2013-2016) mussel survey records in the Suwannee River Basin were compiled, and cumulative discharge contributed by upstream springs...

NOAA’s Deep Sea Coral Research and Technology Program (DSCRTP) is compiling a national database of the locations of deep-sea corals and sponges, beginning in U.S. waters. The DSCRTP will make this information accessible to resource managers, the scientific community, and the public over the World Wide Web. The database fulfills NOAA’s requirements under the Magnuson-Stevens Fishery Conservation and Management Act (MSA) to identify and map locations of deep-sea corals and to submit this information for use by regional fishery management councils. At present, there is no comprehensive, national-scale data portal for deep-sea corals and sponges. Given the authorities outlined in MSA, NOAA’s Deep Sea Coral Research...

Mesopelagic fishes represent an important component of the marine food web due to their global distributions, high abundances and ability to transport organic material throughout a large part of the water column. This study combined stable isotope (SIA) and gut content analyses (GCA) to characterize the trophic structure of mesopelagic fishes in the north central Gulf of Mexico. Additionally this study examined whether mesopelagic fishes utilized chemosynthetic energy from cold seeps. Specimens were collected (9-25 August 2007) over three deep (>1000 m) cold seeps at discrete depths (surface to 1503 m) over the diurnal cycle. Gut content analyses classified 31 species (5 families) of mesopelagic fishes into 5 feeding...

The Nonindigenous Aquatic Species Database (NAS) information resource is an established central repository for spatially referenced biogeographic accounts of introduced aquatic species. The NAS website provides scientific reports, online/real-time queries, spatial data sets, distribution maps, fact sheets, and general information.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
