This dataset contains biological and survey - biological data collected at Cape_Eleuthera_Reefs during deployment Eleuthera_Reef_Surveys_2012 from 2012-07-21 to 2012-07-31. These data include species and taxon_code. These data were collected by Kurt Ingeman and Mark Hixon of Oregon State University as part of the "Ecological Release and Resistance at Sea: Invasion of Atlantic Coral Reefs by Pacific Lionfish (Lionfish Invasion)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-10-31.

The following is the text of the dataset description provided by BCO-DMO:

Size of predators observed during dedicated reef predator searches at Eleuthera, Bahamas.

Dataset Description:
Counts and sizes of fish observed during dedicated reef predator surveys at Eleuthera, Bahamas.

To rigorously test whether and how lionfish have altered prey density-dependent dynamics, a manipulation was conducted of both basslet and lionfish densities in a cross-factored design, such that differences in patterns of mortality between treatments could be attributable to lionfish predation alone. Because density-dependent basslet mortality was attributed to predators aggregating preferentially near high prey concentrations, predatory behavior of both native and invasive predators was also examined in order to determine whether differences in any aggregative response could explain different patterns of prey mortality.

Supplemental Information
Acquisition Description:
During the summer of 2012, a field experiment was conducted on 14 isolated patch reefs near the Cape Eleuthera Institute, Eleuthera, Bahamas. Reefs were paired into blocks by location, size, depth, and vertical relief so that reefs in each block demonstrated similar environmental characteristics. Reefs were then randomly assigned to one of two lionfish treatments: low lionfish reefs (where divers regularly removed lionfish), and high lionfish reefs (where lionfish were added to maintain differential lionfish densities. At each reef, the investigator selected two isolated populations of fairy basslet on small ledges sufficiently separated from each other and from other suitable basslet habitat to inhibit emigration or immigration. Populations were then randomly assigned to either receive artificially increased recruitment or remain unmanipulated. Following the establishment of treatments, the investigator returned to census each population after two days, four days and weekly thereafter, with a final census after four weeks. During each census, the investigator recorded the size of each basslet (adult and juvenile), the total population size, any predators within 2-m of the target basslet ledge, and whether those predators where actively hunting among the experimental basslet populations.
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
