AnotationIn the proposed project, we will focus on several interrelated issues dealing with diversity of European crayfish taxa and populations at different scales: 1) analysis of genetic diversity of invasive crayfish species that may serve as models of impacts of bottleneck effects, colonization history, and reproductive mode variation; 2) experimental work on reproductive strategy of O. limosus, the only so-far known decapod capable of facultative parthenogenesis, and in other invasive cambarid species; 3) analysis of genetic diversity of selected populations of native crayfish species Austropotamobius torrentium and Astacus astacus in Central Europe and identification of their conservation management units; 4) analysis of systematic status and diversity of the economically important Astacus leptodactylus complex, and evaluation of its suspected interspecific hybridization with A. astacus at their secondary contact; 5) application of novel approaches for studying systematically relevant morphological characters in crayfish by transferring know-how from studies on other crustacean groups.
