Confirmation of crayfish plague in Italy: detection of Aphanomyces astaci in white clawed crayfish [PDF]

Diseases of Aquatic Organisms, 2010
In the summer of 2009, high levels of mortality among white clawed crayfish Austropotamobius pallipes were observed in 3 watercourses of central Italy. PCR and culture methods were used to detect the causative agent of the disease. Two strains of Aphanomyces spp.

Origin and colonization history of the white-clawed crayfish, Austropotamobius pallipes, in Ireland [PDF]

Heredity, 2003
The presence of the white-clawed crayfish Austropotamobius pallipes complex in Ireland is suspected to be a result of human translocations. Two hypotheses have been formulated about the origin of the crayfish: from British populations or from western French populations.

Muddied waters: suspended sediment impacts on gill structure and aerobic scope in an endangered native and an invasive freshwater crayfish [PDF]

, 2013
Suspended sediment (SS) loadings in freshwater habitats have increased over the past century and SS is now a significant environmental stressor. Greater tolerance to environmental stressors has been proposed as a factor in the success of aquatic invasive

Simultaneous detection of invasive signal crayfish, endangered white-clawed crayfish and the crayfish plague pathogen using environmental DNA [PDF]

Biological Conservation, 2018
ABSTRACT Aquatic Invasive Species (AIS) are important vectors for the introduction of novel pathogens which can, in turn, become drivers of rapid ecological and evolutionary change, compromising the persistence of native species.

Movement Patterns of the White-clawed Crayfish, Austropotamobius pallipes , in a Tuscan Stream

Journal of Freshwater Ecology, 1998
Abstract We analyzed spatial behavior in the white-clawed crayfish, Austropotamobius pallipes, inhabiting a stream in Tuscany (Italy). Our study suggests an overall complex movement pattern, where nomadic movements are intercalated by stationary phases.

SPECIES OF BRANCHIOBDELLIDAE (ANNELIDA) ON FRESHWATER CRAYFISH IN SOUTH TYROL (NORTHERN ITALY)

Knowledge and Management of Aquatic Ecosystems, 2002
Twenty-eight freshwater crayfish were collected from 8 streams and one small lake in the province of South Tyrol (North Italy) from autumn 1999 to spring 2001, in order to investigate the presence of branchiobdellidans.

The impact of signal crayfish (Pacifastacus leniusculus) on the recruitment of salmonid fish in a headwater stream in Yorkshire, England [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Signal crayfish (Pacifastacus leniusculus) have become increasingly widespread in rivers in Great Britain since their introduction in the late 1970s, causing extensive losses of indigenous white-clawed crayfish and negative impacts on communities of ...

Preliminary disease investigations on white-clawed crayfish Austropotamobius pallipes from streams of Northern Italy.

, 2004
A total of 99 live and 3 dead white-clawed crayfish Austropotamobius pallipes were collected during the summer-autumn 2003 in one creek of Emilia Romagna and four watercourses of Friuli Venezia Giulia in Northern Italy for experimental breeding and ...
