Despite their evolutionary relevance, multispecies networks or syngameons are rarely
reported in the literature. Discovering how syngameons form and how they are maintained …

Phylogenomic data from a rapidly increasing number of studies provide new evidence for
resolving relationships in recently radiated clades, but they also pose new challenges for …

Significant advances have been made in species delimitation and numerous methods can
test precisely defined models of speciation, though the synthesis of phylogeography and …

Abstract Dusky Salamanders (genus Desmognathus) currently comprise only 22 described,
extant species. However, recent mitochondrial and nuclear estimates indicate the presence …

Integrative taxonomy, combining data from multiple axes of biologically relevant variation, is
a major goal of systematics. Ideally, such taxonomies will derive from similarly integrative …

The origin and eventual loss of biogeographic barriers can create alternating periods of
allopatry and secondary contact, facilitating gene flow among distinct metapopulations and …

Genomic‐scale datasets, sophisticated analytical techniques, and conceptual advances
have disproportionately failed to resolve species boundaries in some groups relative to …

Abstract Spotted and Northern Dusky Salamanders (Desmognathus conanti and D. fuscus)
have a long and complex taxonomic history. At least 10 other currently recognized species …

Abstract John Edwards Holbrook published North American Herpetology in 11 volumes from
1836–1842, authoring the first accounts of numerous amphibians and reptiles from the …

The “mountain” dusky is a charismatic ecomorph of Dusky Salamander (Desmognathus):
smaller (~ 20–50mm SVL), more terrestrial and montane woodland species, typically with …
