Romañach, S.S., Beerens, J.M., Hanson, M., and Chapman, J., 2019, Fish data collected during 2015 and 2016 at 9 sites at the Ten Thousand Islands National Wildlife Refuge, Florida: U.S. Geological Survey data release,


Field sampling occurred at locations within Ten Thousand Islands National Wildlife Refuge on three transects along the natural salinity gradient of increasing salinity to the coastal south. We used three replicates per tier (east-west) for a total of nine sampling sites. Sites were approximately 1300 m apart in all directions. Sampling events occurred every 3–4 weeks from January to May for 7 sampling events in 2015 and 5 in 2016. These dates were selected to capture signals of the natural variation in water levels and salinity that occur during the transition from the wet season to the dry season. Fish traps were deployed at each of the nine sites and then retrieved the following day, allowing 24 hours soak time. Two minnow traps [...]

We aimed to examine salinity impacts on presence and abundance of prey fish species in the southwest portion of the Everglades, which is experiencing increasing saltwater intrusion as it awaits ecosystem restoration to send freshwater south toward the coast. Previous research shows that diets high in saltwater prey are detrimental to growth of juvenile water birds such as ibises as well as other freshwater-dependent bird species. Without restoration, rising sea levels and saltwater intrusion will likely continue to contract the foraging habitat available to wetland birds in this important region of the Everglades.
