“…(2013) suggested that with even more sampling effort more and/or new occurrence localities are likely to be discovered for the Yazoo Darter, this would most likely be true for the Sickle Darter as well. Other studies have attempted to capture spatiotemporal variation fish community composition, but many of these studies are done on various temporal scales and do not focus on single species assessments (Calloway et al., 2017; Parks et al., 2014). From a global perspective, most spatiotemporal assessments of freshwater fish distributions have focused on community composition over shorter temporal periods (Garcia et al., 2001; Sylvie et al., 1999).…”

The Sickle Darter Percina williamsi (Page and Near, 2007) is a species of fish endemic to the upper Tennessee River basin in eastern Tennessee, southwestern Virginia, and western North Carolina. Because of its narrow range and presumed decline in occupied sites over the last half century, it is being proposed for federal listing under the Endangered Species Act. We analyzed the current distribution of the Sickle Darter and temporal trends in its distribution in relation to temporal trends in environmental and habitat covariates for each of the historically occupied sub‐basins (upper Clinch, Emory, upper French Broad, Little, Little Pigeon, Middle Fork Holston, North Fork Holston, Powell, South Fork Holston, and Watauga) with multiple linear regression modelling. A total of 154 Sickle Darters were observed at 15 sites throughout the upper Tennessee River Basin. Sickle Darters were observed in the Little River, Emory River, and Middle Fork Holston River sub‐basins. A total of 133 unique historical occurrences were used for the spatiotemporal analyses. Sickle Darters have declined in 8 out of 10 historically occupied sub‐basins. Our best model for the whole distribution scale (Mallow's Cp = −0.87; Adjusted R2 = .92) suggests that habitat fragmentation due to damming has had adverse effects on Sickle Darter populations across its distribution. Models were very similar for the sub‐basin specific models as well. The results from this study highlight the drivers of decline in Sickle Darter distribution and outline the future research needs for this species that should be used to inform future conservation decisions regarding this species.

Checklists are fundamental and important tools for organizing information about biodiversity that provide a basis for conservation and additional scientific research. While Alabama is recognized as an aquatic biodiversity ‘hotspot’ with the highest native freshwater fish diversity in the contiguous United States, we currently lack an up-to-date list of the state’s fishes. In particular, much has changed over the past ~20 years regarding our knowledge of fishes from Alabama and the Mobile River Basin, rendering past comprehensive treatments by Mettee et al. (1996) and Boschung and Mayden (2004) out of date. Here, we provide a revised checklist of marine and freshwater fishes known from the coastal and inland waters of Alabama that includes 463 species (335 primarily freshwater fishes, and 128 marine or diadromous fishes) in 35 orders, 78 families, and 176 genera. Extant, extirpated, and extinct species are included, as are putative candidate species. The checklist is based on prior work, searches of the literature and online sources, as well as parsing a large compilation of >140,000 fish records for Alabama and the Mobile River Basin from 37 data providers in the global Fishnet2 database (www.fishnet2.net) and >4000 marine survey records from the SEAMAP database (https://www.gsmfc.org/seamap.php). After editing and quality control checks, the final combined database contained 144,215 collection records, ~95% of which were georeferenced. We discuss the species descriptions, nomenclatural changes, and updates to marine species that account for changes to the state list, and we close with a discussion of ~13 candidate species forms that remain undescribed, which represent outstanding taxonomic issues in need of further research attention.
