A contribution on the morphometrics of the thick-clawed crayfish Pontastacus pachypus (Rathke, 1837) (Decapoda, Astacoidea, Astacidae) [PDF]

open access: yesZoosystematics and Evolution, 2023
The thick–clawed crayfish Pontastacus pachypus (Rathke, 1837) is an endangered, and the least known, crayfish species in Europe. Currently, detailed information regarding the morphology, ecology and reproduction of thick–clawed crayfish is outdated. This

Genomic and Morphological Evidence Support Contemporary Three-Way Interspecific Hybridization in Ranid Frogs. [PDF]

open access: yesEcol Evol
We investigated natural hybridization among three rapid frogs in eastern Oklahoma. Using genomic SNP data and cranial morphometrics, we confirmed the presence of hybrids exhibiting intermediate traits. Despite overlapping breeding phenologies, minimal introgression suggests hybrid fitness may be considerably lower than that of parental populations ...

Morphological evidence for hidden diversity in the threatened stone crayfish Austropotamobius torrentium (Schrank, 1803) (Decapoda: Astacoidea: Astacidae) in Croatia [PDF]

open access: yesJournal of Crustacean Biology, 2017
The stone crayfish Austropotamobius torrentium (Schrank, 1803) is a native European species distributed in central and southeastern Europe. Recent molecular phylogenetic research has shown that at least seven distinct monophyletic phylogroups exist within A.

Range expansion of the invasive rusty crayfish Orconectes rusticus (Girard, 1852) (Decapoda: Astacoidea) in northeastern Iowa (USA) rivers [PDF]

open access: yesJournal of Crustacean Biology, 2016
The rusty crayfish Orconectes rusticus (Girard, 1852) is an invasive species that has been introduced to the Upper Midwest, USA from the Ohio River Valley, and is associated with ecological damage to aquatic systems. We examined the distributions of rusty and native crayfishes in two Iowa river systems.

The phylogenetic position of the East Asian freshwater crayfish Cambaroides within the Northern Hemisphere Astacoidea (Crustacea, Decapoda, Astacida) based on molecular data

open access: yesJournal of Zoological Systematics and Evolutionary Research, 2006
The phylogenetic position of the four East Asian freshwater crayfish species of the genus Cambaroides is not settled. Morphological phylogenetic analyses suggest close affinities of Cambaroides with North American Cambaridae. This view is based mainly on characters of the male and female reproductive organs. In contrast, the only molecular phylogenetic

A Scanning Electron Microscopic Study on the Appendage Morphology of Astacus leptodactylus (Eschscholtz, 1823) and Pacifastacus leniusculus (Daña, 1852) (Crustácea:Decapoda: Astacoidea) [PDF]

open access: yesInternational Journal of Morphology, 2008
Este estudio compara la morfologia del rostro, pereiopodos 1,2,4 y piezas bucales de los Astacus leptodactylus jovenes con los de Pacifastacus leniusculus. Se observaron las diferencias en la morfologia, en particular, con respecto a las piezas bucales, por ejemplo incluyendo la armadura setal y el numero de dientes en la mandibula.
