BIOCIDE TREATMENT OF PONDS IN SCOTLAND TO ERADICATE SIGNAL CRAYFISH [PDF]
Bulletin Français de la Pêche et de la Pisciculture, 2006 This trial aimed to eradicate illegally introduced signal crayfish Pacifastacus leniusculus in the North Esk catchment, Scotland. Sites treated were (1) an isolated gravel-pit (c. 9,000 m3), with crayfish present for 6 years; (2) three dammed ponds, (c. 5,000 m3) and (3) a leaking, offline pond (c. 6,000 m3), with crayfish for two years.

The Anatomical Record, EarlyView.Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

STATUS OF FRESHWATER CRAYFISH IN LATVIA
Knowledge and Management of Aquatic Ecosystems, 2005 There are three crayfish species present in Latvia: the European noble crayfish (Astacus astacus), the narrow-clawed crayfish (Astacus leptodactylus), and the North-American signal crayfish (Pacifastacus leniusculus) species. Probably only noble crayfish
