Aquatic macroinvertebrate responses to native and non-native predators [PDF]

, 2014
Non-native species can profoundly affect native ecosystems through trophic interactions with native species. Native prey may respond differently to non-native versus native predators since they lack prior experience.

SYNTOPY OF A. PALLIPES AND A. ITALICUS: GENETIC AND MORPHOMETRICAL INVESTIGATIONS

Knowledge and Management of Aquatic Ecosystems, 2006
Genetic studies on the populations of Austropotamobius pallipes complex from Alessandria province (N-Italy), conducted on the basis of variations recorded in the sequences of mitochondrial DNA in the gene 16S RNA, have allowed to single out an ...

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.

Habitat use by the endangered white-clawed crayfish Austropotamobius species complex: a systematic review

Knowledge and Management of Aquatic Ecosystems, 2017
Understanding habitat requirements is a key part of conserving declining species, particularly when reintroductions are planned as part of the recovery strategy.

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal Conservation, Volume 29, Issue 3, Page 274-284, June 2026.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

Systematics of the European Endangered Crayfish Species Austropotamobius Pallipes (Decapoda: Astacidae) [PDF]

Journal of Crustacean Biology, 2000
Abstract Mitochondrial DNA sequence variation in the 16S rRNA gene was used to estimate the phylogenetic relationships of Austropotamobius pallipes. The program ModelTest was used to test alternative models of evolution for our data using likelihood ratio tests.

Molecular Characterisation of Endangered White‐Clawed Crayfish Populations in Southern Switzerland

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT This study investigates the phylogeography of the endangered European White‐Clawed Crayfish (WCC) Austropotamobius pallipes species complex in the main tributaries of the Po River basin in southern Switzerland and northern Italy, a diversity hotspot for this species.

Spatial ecology of white-clawed crayfish Austropotamobius pallipes and signal crayfish Pacifastacus leniusculus in upland rivers, Northern England [PDF]

, 2004
The American signal crayfish Pacifastacus lernusculus, an invasive species widely introduced throughout Europe, is a major threat to native European crayfish species and is causing increasing concern because of its wide impact on aquatic ecosystems. This

Distribution and biometry of native and alien crayfish in Trentino (Italian Alps)

Journal of Limnology, 2013
To fill the existing gaps in the knowledge of the crayfish species distribution in Trentino region (North-East Italy), we surveyed fourteen lakes, six ponds and sixty-nine creeks and streams in 2010-2012.

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...
