Historical data show that the native white-clawed crayfish, Austropotamobius pallipes, was once widespread throughout South Tyrol (northern Italy), whereas recent studies identified only half a dozen remaining populations. In order to implement conservation strategies based on knowledge of genetic diversity, each of the six remaining populations in South Tyrol and one population in Tyrol (Austr...

Abstract The white-clawed crayfish, Austropotamobius pallipes is endangered throughout its entire biogeographic range in Europe due to infection with Aphanomyces astaci (crayfish plague) and habitat deterioration. Ex situ propagation of increasing importance safeguard genetic resources enable restocking measures after the pathogen’s disappearance. This study aimed quantify impact crude protein ...

The stone crayfish, Austropotamobius torrentium, is a European freshwater crayfish. Although this species relatively widespread throughout the continent, it undergoing significant declines its range. However, as decline rates have not been quantified in detail, classified data deficient by IUCN Red List of Threatened Species. present study describes development and validation two species-specif...

2,4-D is a widely used phenoxy herbicide, potentially toxic to humans and biota. The objective of the present study was to reveal short term sublethal effects of 2,4-D on narrow-clawed freshwater crayfish (Astacus leptodactylus Eschscholtz, 1823), based on histology, total haemocyte counts, selected haemolymph parameters, and oxidative stress parameters. In the laboratory conditions crayfish sp...
