Overland Movement and Activity of the Endangered White-Clawed Crayfish Austropotamobius Pallipe

open access: yes
The UK’s only native crayfish, the white-clawed crayfish Austropotamobius pallipes, is \ud endangered and in decline across its range in Europe. The principle threat derives from \ud the introduction, accidental and deliberate, of invasive crayfish species, which lead to \ud losses of native crayfish through transmission of crayfish plague Aphanomyces ...

Conservation of the native white-clawed crayfish, Austropotamobius pallipes, in the uplands of mid-Wales [PDF]

open access: yes
British native white-clawed crayfish, Austropotamobius pallipes, thrive in calcium rich freshwaters, but have declined dramatically in the last few decades due to competition with invasive species, disease, loss of habitat and pollution. This thesis examines the current status of Welsh A.

The white-clawed crayfish in Spain—reply to Clavero and Centeno-Cuadros

Organisms Diversity & Evolution, 2016
This short communication is only intended to point out briefly and objectively some of the comments, appreciations, and sometimes misinterpretations made by Clavero and CentenoCuadros in their criticism to our article on the phylogeography of the white-clawed crayfish in Spain, recently published in this journal.

Insights into the molecular phylogeny and historical biogeography of the white-clawed crayfish (Decapoda, Astacidae)

Molecular Phylogenetics and Evolution, 2016
In this study, the evolutionary history of the white-clawed crayfish (WCC) was evaluated using large-scale datasets comprising >1350 specimens from the entire distribution range. Using species delimitation methods on mitochondrial DNA (mtDNA) sequences, we propose four primary species hypotheses for WCC.

The significance of chelae in the agonistic behaviour of the white‐clawed crayfish,a Ustropotamobius pallipes

Marine and Freshwater Behaviour and Physiology, 2000
As in other benthic decapods, crayfish have chelae that are important for intra‐specific agonistic encounters. In Austropotamobius pallipes, scars and mutilations are present mostly on the chelae, these being the main targets of agonistic contacts. Because males participate in more aggressive interactions than females do and compete with other males ...

Use of Ephemeroptera as bioindicators of the occurrence of white-clawed crayfish (Austropotamobius pallipes)

Hydrobiologia, 2011
Currently, the distribution of the European native white-clawed crayfish (Austropotamobius pallipes) is restricted, fragmented and mainly located in headwater streams. Many European countries have active programmes for its conservation and some also have reintroduction programmes.

Phylogeography of the white-clawed crayfish (Austropotamobius italicus) in Spain: inferences from microsatellite markers

Molecular Biology Reports, 2013
The white-clawed crayfish (Austropotamobius italicus), a cornerstone of Spain's aquatic ecosystems, was once widely distributed throughout much of the country. Unfortunately, its populations have suffered very strong declines over the last 40 years due to the spread of introduced species (red swamp and signal crayfishes), diseases, habitat loss and ...
