Austropotamobius pallipes reduction vs. Procambarus clarkii spreading: Management implications

Journal for Nature Conservation, 2014
One of the main threats to native European crayfish is the spread of alien crayfish species that are immune carriers of the detrimental crayfish plague Aphanomyces astaci. In this study we analyzed both at a regional and at a local scale factors determining native and alien crayfish distribution in an area where the species Procambarus clarkii is ...

Morphometrical characterization of theAustropotamobius pallipesspecies complex

Journal of Natural History, 2008
Genetic studies have shown that the threatened crayfish Austropotamobius pallipes species complex is composed of two lineages (A. italicus and A. pallipes), both occurring in Italy. However, the issue surrounding their taxonomic status has not yet been solved even though the confused taxonomy may hamper attempts to conserve indigenous crayfish. The aim

Mitochondrial DNA variation and population genetic structure of the white-clawed crayfish, Austropotamobius pallipes pallipes

Conservation Genetics, 2000
Here we report a high level of mtDNA variationfrom RFLP analysis within A. p. pallipes from 21 French and 4British populations. Seventeen haplotypes were recorded among 269individuals. Nucleotide sequence divergence (p) among mtDNAhaplotypes ranged from 0.0019 to 0.0425.

The setae of Austropotamobius pallipes (Crustacea: Astacidae)

Journal of Zoology, 1970
The author presents here the results of an introductory study into the setal armature of the British species of crayfish, Austropotamobius pallipes (Lereboullet, 1858). Using an ordinary optical microscope, it is demonstrated that a considerable variety of setae exist on the body and appendages of A. pallipes.

Metal ion metabolism in the moulting crayfish (Austropotamobius pallipes)

Comparative Biochemistry and Physiology Part A: Physiology, 1982
Abstract 1. 1. The hepatopancreas, antennal gland, gills, gonads. muscle, stomach, carapace, gastroliths and blood of 52 crayfish (Austropotamobius pallipes) have been analysed for copper, zinc, iron, manganese and calcium throughout the moult cycle. 2. 2. There are significant changes in most of these metals at the time of ecdysis. 3. 3.

Hemolymph phenol oxidases in Drosophila melanogaster, Locusta migratoria, and Austropotamobius pallipes

Biochemical and Biophysical Research Communications, 1991
The early enzyme-mediated reaction sequence in the biosynthesis of melanin from L-tyrosine involves an initial hydroxylation (monophenol oxidase activity, MPO) of the aromatic amino acid precursor to form L-dopa (3,4-dihydroxyphenylalanine), and the ensuing oxidation (diphenol oxidase activity, DPO) of the resultant diphenol to form dopaquinone.
