Population ecology of endangered white-clawed crayfish (Austropotamobius pallipes s. str.) in a small rhithral river in Germany

Knowledge and Management of Aquatic Ecosystems, 2015
Sound knowledge on distribution and ecology of imperiled species is an essential prerequisite for effective conservation planning. Here, we report the distribution and autecological traits of a newly discovered population of ...

First record of the stone crayfish in the Romanian lowlands

Knowledge and Management of Aquatic Ecosystems, 2021
The stone crayfish is a native European freshwater species with significant population declines caused by anthropogenic pressure onto its habitats, climate change and spreading of non-indigenous invasive crayfish and their pathogens (e.g., Aphanomyces ...

Two indigenous European crayfish under threat – how can we retain them in aquatic ecosystems for the future?

Knowledge and Management of Aquatic Ecosystems, 2011
Indigenous crayfish species (ICS) are under threat in Europe; due to competition from invasive non-indigenous crayfish species (NICS) from crayfish plague, which is carried by introduced American crayfish, and habitat degradation.

First record of an introduced population of the southern lineage of white-clawed crayfish (Austropotamobius ‘italicus’) north of the Alps

Knowledge and Management of Aquatic Ecosystems, 2015
Elucidating the status of populations of endangered species of unclear origin may have important implications for conservation management. In September 2013, a population of white-clawed crayfish was discovered outside of the native ...

Placement matters: Implications of trail- versus random-based camera-trap deployment for monitoring mammal communities. [PDF]

Ecol Appl
Abstract Optimizing protocols to assess and monitor mammal communities is essential to meet the current biodiversity targets of halting species loss. Camera‐traps are the most effective tool for multispecies monitoring, yet their deployment strategy is debated, with two main strategies adopted: trail‐ and random‐based camera deployment.

COMPARISON OF WHITE-CLAWED CRAYFISH POPULATIONS IN IRISH AND FRENCH STREAMS, WITH COMMENTS ON ITS FUTURE SURVIVAL IN EUROPE

Knowledge and Management of Aquatic Ecosystems, 2006
White-clawed crayfish Austropotamobius pallipes (Lereboullet) populations remain strong in Ireland across a range of river and lake habitats, but the species is in decline elsewhere in Europe where it is sympatric with alien species.

Native and Invasive Crayfish Species Impact on the Development of Fire Salamander Larvae: A Pilot Field Study From Northern Italy

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT In northern Italy, the ongoing spread of non‐native red‐swamp crayfish Procambarus clarkii keeps indirectly decimating native populations of white‐clawed crayfish Austropotamobius pallipes complex and is now also threatening local amphibians adapted to slow‐flowing, hilly streams at the borders of its distribution.
