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]

Journal of Crustacean Biology, 2018
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

Analysis and description of burrow structure in four species of freshwater crayfishes (Decapoda: Astacoidea: Cambaridae) using photogrammetry to recreate casts as 3D models

Journal of Crustacean Biology, 2019
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 ...

Claw morphology, claw strength, and fighting behavior in the New River crayfishCambarus chasmodactylusJames, 1966 (Decapoda: Astacoidea: Cambaridae)

Journal of Crustacean Biology, 2021
AbstractDespite the diversity in the size, performance, and function of crustacean claws (chelae), our understanding of the functional morphology and evolution of these claws are lacking. Since crayfish claws are multi-function organs that face selection from fighting, mating, foraging, and predation, these pressures all interact to shape the claws ...

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

Journal 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
