Functional analysis of a mutated analogue of the crustacean hyperglycaemic hormone from the crayfish Pontastacus leptodactylus

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2015
ABSTRACTThe crustacean hyperglycaemic hormone (CHH), a pleiotropic neuropeptide, belongs to a family of structurally related peptides, having six cysteine residues in conserved positions forming three disulphide bridges, and regulating several physiological processes in crustaceans and insects.

Multi-method distribution modelling of an invasive crayfish (Pontastacus leptodactylus) at Eurasian scale [PDF]

Hydrobiologia
Abstract Globally, human activities profoundly influence biodiversity, frequently favouring biological invasions. Crayfish, prominent invaders on multiple continents, pose significant varied threats. Using species distribution models (SDMs), this study explores the current and future potential distribution of Pontastacus leptodactylus, a ...

Cheliped loss and abnormalities of the narrow-clawed crayfish, Pontastacus leptodactylus (Eschscholtz, 1823) (Crustacea: Decapoda: Astacidae) [PDF]

Nauplius
Heterochely is an important phenomenon in decapod crustaceans. Nevertheless, it was rarely examined in freshwater crayfish. Therefore, the aim of this study was to investigate cheliped loss and abnormalities of the narrow-clawed crayfish, Pontastacus ...

A contribution on the morphometrics of the thick-clawed crayfish Pontastacus pachypus (Rathke, 1837) (Decapoda, Astacoidea, Astacidae) [PDF]

Zoosystematics and Evolution, 2023
The thick–clawed crayfish Pontastacus pachypus (Rathke, 1837) is an endangered, and the least known, crayfish species in Europe. Currently, detailed information regarding the morphology, ecology and reproduction of thick–clawed crayfish is outdated. This

Some effects of experimental acidification on phenoloxidase, trypsin and lysozyme activities in freshwater crayfish (Pontastacus leptodactylus)

, 2008
Levels of phenoloxidase (Po), trypsin and lysozyme activities were determined following 48 hours exposing freshwater crayfish (Pontastacus leptodactylus) weighing 59.8±3.4g to different low pH values of 6.5, 5.5, 4 and 2.5 at 20-23˚C.

Phylogeographic patterns of genetic diversity in Pontastacus leptodactylus (Decapoda: Astacidae): is the hypothesis of the taxonomically rich genus Pontastacus true?

Zoological Journal of the Linnean Society, 2023
Abstract The narrow-clawed crayfish Pontastacus leptodactylus is a large native European astacid crayfish species distributed in the drainage area of the Azov, Black and Caspian Seas. The species shows immense morphological diversity across its range. Various species and subspecies have been described and, recently, eight species and two

Influence of distance from source population and seasonality in eDNA detection of white‐clawed crayfish, through qPCR and ddPCR assays

Environmental DNA, Volume 5, Issue 4, Page 733-749, July 2023., 2023
Abstract The white‐clawed crayfish (Austropotamobius pallipes) is an emblematic taxon of European rivers, found mainly in oxygenated streams, known to be an excellent indicator of river quality. Since several decades, the population of A. pallipes declined in relation to anthropogenic pressure, habitat loss, and competition with pests (invasive ...
