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...

The data set associated with this metadata is included in three separate csv files: 'Occupancy_Data', 'Stage_Raw', and 'Flood_Stage_Height'. 'Occupancy_Data' was used to fit the dynamic occupancy models and includes 17 columns: Time: time periods numbered 1 to 5; 'Oxbow': individual oxbows numbered 1 through 10; 'OxbowName': the name of each oxbow; 'Species': species encountered during sampling, numbered 1 to 16; 'SpeciesName': common and scientific names for each species; 'Occ1', 'Occ2', 'Occ3': detection (1) and non-detection data for each Time, Oxbow, Species combination across 3 survey occasions (NAs represent surveys that did not occur); Binary-coded life history characteristics (traits) for each species:...
