Evaluation of Three Monitoring Methods for the Native European Crayfish Austropotamobius torrentium

Freshwater Crayfish, 2023
Abstract For the stone crayfish, a threatened species listed in the Habitats Directive in Annex II and V, three monitoring methods were evaluated: hand capture by day, hand capture by night and eDNA sampling respectively. The lack of a standardized sampling method in Austria and the simultaneous obligation to monitor and report on the status of ...

Habitat and shelter requirements of the stone crayfish, Austropotamobius torrentium Schrank

Hydrobiologia, 2002
The attractiveness of shelters and the relationship between crayfish size and refuge size were investigated in the stone crayfish Austropotamobius torrentium. Shelter suitability was mainly determined by water velocity, stone surface area and stone width. Water depth and stone height had no influence on crayfish occupancy of stones.

Evolutionary history of Austropotamobius torrentium

2019
Austropotamobius torrentium is a freshwater crayfish species distributed across central and south-eastern Europe, with the highest genetic diversity recorded in the northern-central Dinarides. Previous studies have shown that evolutionary history of A. torrentium was shaped through different paleohydrologic and paleogeologic events from Miocene onwards.
