Abstract National parks and other protected areas are important for preserving landscapes and biodiversity worldwide. An essential component of the mission of the United States (U.S.) National Park Service (NPS) requires understanding and maintaining

Candidate‐species delimitation in Desmognathus salamanders reveals gene flow across lineage boundaries, confounding phylogenetic estimation and clarifying hybrid zones

Autor: Robert Alexander Pyron, Kyle A. O’Connell, Emily Moriarty Lemmon, Alan R. Lemmon, David A. Beamer

Publikováno v: Ecology and Evolution, Vol 12, Iss 2, Pp n/a-n/a (2022)

Abstract Dusky Salamanders (genus Desmognathus) currently comprise only 22 described, extant species. However, recent mitochondrial and nuclear estimates indicate the presence of up to 49 candidate species based on ecogeographic sampling. Previous st

A systematic revision of the Shovel-nosed Salamander (Plethodontidae: Desmognathus marmoratus), with re-description of the related D. aureatus and D. intermedius

Autor: R. ALEXANDER PYRON, DAVID A. BEAMER

Publikováno v: Zootaxa. 5270:262-280

Shovel-nosed Salamanders, Desmognathus marmoratus (Moore, 1899), were long thought to represent a single species from the southern Appalachian Mountains of the eastern United States, ranging from northeastern Georgia to extreme southwestern Virginia.

Speciation Hypotheses from Phylogeographic Delimitation Yield an Integrative Taxonomy for Seal Salamanders (Desmognathus monticola)

Autor: R Alexander Pyron, Kyle A O’Connell, Sophie C Duncan, Frank T Burbrink, David A Beamer

Publikováno v: Systematic Biology. 72:179-197

Significant advances have been made in species delimitation and numerous methods can test precisely defined models of speciation, though the synthesis of phylogeography and taxonomy is still sometimes incomplete. Emerging consensus treats distinct ge

Allocation of Salamandra auriculata Holbrook, 1838, with a new species of swamp-dwelling dusky salamander (Plethodontidae: Desmognathus) from the Atlantic Coastal Plain

Autor: R. ALEXANDER PYRON, DAVID A. BEAMER

Publikováno v: Zootaxa. 5188:587-595

Most swamp-dwelling dusky salamanders of the genus Desmognathus from the Coastal Plain were long treated as a single species (Desmognathus auriculatus) ranging from east Texas to southeastern Virginia. This taxon concept was based on the name Salaman

Understanding 'Alexandrian' extinctions using genomic DNA from fluid-preserved museum specimens of Desmognathus salamanders

Autor: Kyle A. O’Connell, David A. Beamer, Alex Pyron, Chace R. Holzheuser, Addison H. Wynn, Alan R. Lemmon, Emily Moriarty Lemmon

Species that went extinct prior to the genomic era are typically out-of-reach for modern phylogenetic studies. We refer to these as “Alexandrian” extinctions, after the lost library of the ancient world. This is particularly limiting for conserva
