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 distribution of crayfish (Decapoda, Astacoidea) and branchiobdellids (Annelida, Clitellata) in Vienna, Austria

, 2018
Flusskrebse (Decapoda, Astacidea) werden aufgrund mannigfaltiger Interaktionen mit anderen Arten, sowie physikalischer Einflüsse auf ihr Habitat oft als Schlüsselarten von Süßwassersystemen betrachtet. Der Verlust von Flusskrebspopulationen, aber auch die Migration eingeführter Flusskrebsarten, kann die lokale Biodiversität gravierend beeinträchtigen ...
