Cloning and functional characterization of a TMC-like channel gene and protein in the crayfish Astacus leptodactylus (Eschscholtz, 1823) (Decapoda: Astacidea: Astacidae)

Journal of Crustacean Biology, 2023
Ion channels gated selectively by mechanical stimulus are the key elements of mechanosensation. Several genes have been associated with putative mechanosensitive ion channels or mechanosensitive channel complexes.

Les introductions de crustacés décapodes d'eau douce en France. Peut-on parler de gestion ? [PDF]

Knowledge and Management of Aquatic Ecosystems, 1997
La proportion d'espèces allochtones dans les peuplements français de crustacés décapodes d'eau douce est importante. Pour deux espèces de crevettes (famille des Atyidae) et trois espèces d'écrevisses (famille des Astacidae) autochtones, on compte quatre ...

Filling the gaps in the genetic diversity of Austropotamobius torrentium (Astacidae, Decapoda) from one of the few unexplored hot spots

Knowledge and Management of Aquatic Ecosystems
Recent molecular analyses of the stone crayfish have revealed a high degree of genetic diversity. The greatest diversity is found in the western Balkans (Dinarides), where more than half of the known phylogroups exist in a relatively small geographical ...

A PROPOSAL FOR ACCEPTING PONTASTACUS AS A GENUS OF EUROPEAN CRAYFISH WITHIN THE FAMILY ASTACIDAE BASED ON A REVISION OF THE WEST AND EAST EUROPEAN TAXONOMIC LITERATURE

Knowledge and Management of Aquatic Ecosystems, 2006
The taxonomic classification of European crayfish is neither fully examined nor generally accepted as a unifying scheme. At present, one of the most obvious differences exists between astacologists from Western and Eastern Europe.
