HABITAT PREFERENCE OF DIFFERENT SIZE CLASSES OF AUSTROPOTAMOBIUS PALLIPES IN AN IRISH RIVER

Knowledge and Management of Aquatic Ecosystems, 2003
Juvenile and immature crayfish are more difficult to find than adults and in consequence rather little is known about their habitat preferences. Smaller crayfish are able to inhabit different areas within the stream compared to adult crayfish.

Induction of ovarian maturation by means of dietary hormonal treatment in Austropotamobius pallipes

Italian Journal of Animal Science, 2010
The freshwater crayfish Austropotamobius pallipes is an annual species with low fecundity and a long embryonic development. Restocking programmes for this species have recently been prompted in many countries in Europe because of its ecological ...

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.

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.

Interdisciplinarity to reconstruct historical introductions: solving the status of cryptogenic crayfish [PDF]

, 2017
Anciently introduced species can be confounded with native species because introduction pre-dates the first species inventories or because of the loss of the collective memory of the introductions.

HIGH DISPERSAL ABILITY OF AUSTROPOTAMOBIUS PALLIPES REVEALED BY MICROSATELLITE MARKERS IN A FRENCH BROOK

Knowledge and Management of Aquatic Ecosystems, 2002
The genetic structure of a large population of the white-clawed crayfish Austropotamobius pallipes was assessed with five microsatellite markers by sampling six sites along its extent.

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal Conservation, EarlyView.
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 ...
