New County Records and Other Data Since 1996
Eurycea aquatica Rose & Bush, Brown-backed Salamander
Since publication of Atlas of Amphibians in Tennessee (Redmond, W. H. and A. F. Scott. 1996. The Center for Field Biology, Austin Peay State University, Clarksville, TN. 94 pp.), several applicable taxonomic and nomenclatural changes and numerous reports of new county records have appeared in the literature. Comments, accompanied by cited references, on the taxonomic and nomenclatural changes, plus an updated distribution map and bibliographical information on new county records as they pertain to E. aquatica follow:
Taxonomic and Nomenclatural Changes
Using a multiple-analysis approach, Kozak et al. (2006) studied the phylogenetic variation of the Eurycea bislineata species complex and proposed that Eurycea aquatica is a legitimate taxon as described by Rose & Bush (1963). Further evidence to support this proposal was provided by Timpe et al. (2009) who demonstrated that E. aquatica from isolated springs in Georgia, Alabama, and Tennessee (Bradley County) form a well-supported monophyletic group that is nested among E. cirrigera, E. wilderae, and E. junaluska.
