Observation of museum specimens of the genus Pacifastacus Bott, 1950 (Decapoda: Astacidae)

Nauplius, 2018
Until recently, three subspecies had traditionally been recognized in the astacid species Pacifastacus leniusculus (Dana, 1852): Pacifastacus leniusculus leniusculus, Pacifastacus leniusculus klamathensis (Stimpson, 1857), and Pacifastacus leniusculus ...

Better Alone Than in Bad Company: Trophic Ecology of Co-Occurring Invasive and Native Crayfish. [PDF]

Ecol Evol
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

Diel turbidity cycles in a headwater stream: evidence of nocturnal bioturbation? [PDF]

, 2016
Purpose: A small number of recent studies have linked daily cycles in stream turbidity to nocturnal bioturbation by aquatic fauna, principally crayfish, and demonstrated this process can significantly impact upon water quality under baseflow conditions ...

Competition and parasitism in the native White Clawed Crayfish Austropotamobius pallipes and the invasive Signal Crayfish Pacifastacus leniusculus in the UK [PDF]

, 2009
Many crayfish species have been introduced to novel habitats worldwide, often threatening extinction of native species. Here we investigate competitive interactions and parasite infections in the native Austropotamobius pallipes and the invasive ...

DISTRIBUTION AND REPRODUCTIVE BIOLOGY OF AUSTROPOTAMOBIUS TORRENTIUM IN BAVARIA AND DOCUMENTATION OF A CONTACT ZONE WITH THE ALIEN CRAYFISH PACIFASTACUS LENIUSCULUS

Knowledge and Management of Aquatic Ecosystems, 2005
In Bavarian freshwater systems, the stone crayfish Austropotamobius torrentium is still present in many headwaters of Danubian tributaries. Since the 1960s an alien species, the signal crayfish Pacifastacus leniusculus, was introduced several times ...
