Book excerpt: "Abstract: Dusky salamanders (Desmognathus) constitute a large, species-rich group within the family Plethodontidae, and though their systematic relationships have been addressed extensively, most studies have centered on particular species complexes and therefore offer only piecemeal phylogenetic perspective on the genus. Recent work has revealed Desmognathus to be far more clade rich--35 reciprocally monophyletic clades versus 22 recognized species--than previously imagined, results that, in turn, provide impetus for additional survey effort within clades and across geographic areas thus far sparsely sampled. We conceived and implemented a sampling regime combining level IV ecoregions and independent river drainages to yield a geographic grid for comprehensive recovery of all genealogically exclusive clades. We sampled over 550 populations throughout the distribution of Desmognathus in the eastern United States of America and generated mitochondrial DNA sequence data (mtDNA; 1,991 bp) for 536 specimens. A Bayesian phylogenetic reconstruction of the resulting haplotypes revealed forty-five reciprocally monophyletic clades, eleven of which have never been included in a comprehensive phylogenetic reconstruction, and an additional three not represented in any molecular systematic survey. Although general limitations associated with mtDNA data preclude new species delineation, we profile each of the 45 clades and assign names to 10 new clades (following a protocol for previous clade nomenclature). We also redefine several species complexes and erect new informal species complexes. Our dataset, which contains topotypic samples for nearly every currently recognized species and most synonymies, will offer a robust framework for future efforts to delimit species within Desmognathus. Keywords: Amphibia, Caudata, Desmognathus, mtDNA phylogeny, level IV ecoregion X independent drainage sampling, new clades"--Page 3.

Available in PDF, EPUB and Kindle. Book excerpt: The dusky salamanders (Desmognathus) constitute a large, species-rich group, and although a considerable body of literature exists on systematic relationships and adaptive trends, these issues have heretofore been approached in piecemeal fashion. Recent work has revealed Desmognathus to be far more lineage rich than previously imagined and demonstrated just how complex the taxon's evolutionary history has been. These recent advances underscore the need for additional sampling in areas and within lineages that have thus far been sparsely evaluated. I conceived and implemented a sampling regimen involving level IV ecoregion X independent river drainages designed for the comprehensive recovery of all genealogically exclusive lineages within the genus. I sampled over 550 populations across the range-wide distribution of described dusky salamander species and generated mtDNA sequence data for each population. A Bayesian phylogenetic reconstruction of the resulting haplotypes revealed forty-five independent evolutionary lineages, eleven of which have never been included in a comprehensive phylogenetic reconstruction and three of which have not been included in any molecular systematic survey. Although general limitations associated with mtDNA data preclude delineation of new species, I have redefined several species complexes and have also erected new informal species complexes. The dataset assembled here, which contains topotypic samples for all currently recognized species as well as most synonymies, should serve as a robust framework for future efforts to delimit species within Desmognathus.
