Using genomics, morphometrics, and environmental niche modeling to test the validity of a narrow-range endemic snail, Patera nantahala (Gastropoda, Polygyridae)

Autor: Nathan V. Whelan, Ellen E. Strong, Nicholas S. Gladstone, Jason W. Mays

Publikováno v: ZooKeys, Vol 1158, Iss , Pp 91-120 (2023)

Terrestrial gastropods are among the most imperiled groups of organisms on Earth. Many species have a complex taxonomic history, often including poorly defined subspecies, most of which have not been the focus of modern systematics research. Genomic

Autor: Alexander Czaja, Nicholas S. Gladstone, Jorge Luis Becerra-López, José Luis Estrada-Rodríguez, Jorge Sáenz‑Mata, Fernando Hernández-Terán

Publikováno v: Subterranean Biology, Vol 39, Iss , Pp 129-141 (2021)

This paper describes a new genus and species of subterranean gastropod from a karstic region near Viesca, Coahuila in northern Mexico. Shells of Phreatoviesca spinosa gen. nov. et sp. nov. were found in spring-deposited sediments near the outlet of a

Spatiotemporal patterns of non-native terrestrial gastropods in the contiguous United States

Autor: Nicholas S. Gladstone, Trystan A. Bordeau, Christy Leppanen, Michael L. McKinney

Publikováno v: NeoBiota, Vol 57, Iss , Pp 133-152 (2020)

The contiguous United States (CONUS) harbor a significant non-native species diversity. However, spatiotemporal trends of some groups such as terrestrial gastropods (i.e., land snails and slugs) have not been comprehensively considered, and therefore

Morphometrics and phylogeography of the cave-obligate land snail Helicodiscus barri (Gastropoda, Stylommatophora, Helicodiscidae)

Autor: Nicholas S. Gladstone, Matthew L. Niemiller, Evelyn B. Pieper, Katherine E. Dooley, Michael L. McKinney

Publikováno v: Subterranean Biology, Vol 30, Iss , Pp 1-32 (2019)

Molecular studies have recently led to the detection of many cryptic species complexes within morphologically ambiguous species formerly undescribed by the scientific community. Organisms such as land snails are at a particularly higher risk of speci

A new maximum body size record for the Berry Cave Salamander (Gyrinophilus gulolineatus) and genus Gyrinophilus (Caudata, Plethodontidae) with a comment on body size in plethodontid salamanders

Autor: Nicholas S. Gladstone, Evin T. Carter, K. Denise Kendall Niemiller, Lindsey E. Hayter, Matthew L. Niemiller

Publikováno v: Subterranean Biology, Vol 28, Iss , Pp 29-38 (2018)

Lungless salamanders in the family Plethodontidae exhibit an impressive array of life history strategies and occur in a diversity of habitats, including caves. However, relationships between life history, habitat, and body size remain largely unresol
