| Title: | Results of experiment comparing herbivorous fish grazing at reefs with manipulated lionfish densities at Lee Stocking Island, Bahamas in 2011 (Lionfish Invasion project) (NCEI Accession 0277328) |
| Abstract: | This dataset contains biological and survey - biological data collected at Tropical Marine Lab at Lee Stocking Island during deployment LSI_Reef_Surveys_09-12 in the North Atlantic Ocean from 2011-07-22 to 2011-07-31. These data include family. These data were collected by Mark Hixon and Tye L. Kindinger 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 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: Experiment comparing herbivorous fish grazing at reefs with manipulated lionfish densities. Dataset Description: A field experiment was conducted at Lee Stocking Islands, Bahamas from 07/22/2011 to 07/31/2011 to study the grazing activity of herbivorous fishes at reefs with manipulated lionfish ( Pterois volitans ) densities (low and high). |

| Supplementary information: | Acquisition Description: The grazing rates of herbivorous fishes (bites/time) and the resulting algal loss rates (change in percent cover/time) were measured on paired-by-treatment, algal-covered substrata. At reefs with high lionfish densities, treatments consisted of the presence vs. absence of lionfish in local habitats where algal-covered substrata were distributed. Reefs with low lionfish densities included only the lionfish-absent treatment. Divers counted the number of bites on each replicate sample of algal-covered substratum for each herbivore observed during each of 16 replicate 20-min observation periods per reef. Herbivore behavior was sampled by 4 replicate 60-min automated video observations per reef. Each grazing herbivore was identified to the species-level and its total body length was estimated visually. Changes in percent algal cover were measured from before-after photographs of each replicate substratum using ImageJ. |
