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

Abundance and habitat associations of two Florida crayfishes, Procambarus paeninsulanus (Faxon, 1914) and P. fallax (Hagen, 1870) (Decapoda: Astacoidea), assessed with N-mixture modeling [PDF]
The study of crayfishes in their native habitats is limited, even if crayfishes are economically and ecologically important. Such is the case in southeastern USA, a center of global crayfish diversity. This study investigated model-estimated abundance and habitat associations of Procambarus paeninsulanus (Faxon, 1914) and P. fallax (Hagen, 1870) in two

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

AbstractFreshwater crayfishes use burrows for predator avoidance, desiccation prevention, foraging, and brood care. Based on their burrow ecology, crayfishes can be categorized as tertiary, secondary, or primary burrowers, with primary burrowers being semi-terrestrial and highly dependent on burrows for survival; secondary and tertiary burrowers have ...

Karyological analysis of freshwater crayfish Austropotamobius pallipes (Lereboullet, 1858) and Austropotamobius torrentium (Schrank, 1803) [PDF]
Provedeno je kariološko-citogenetičko istraživanje na europskim autohtonim vrstama rakova Austropotamobius pallipes i A. torrentium iz porodice Astacidae. Vrsta A. pallipes ima diploidan broj kromosoma 2n=168, a vrsta A. torrentium ima 2n=164.
