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 ...

DETERMINATION OF THE RATE OF GROWTH OF PACIFASTACUS LENIUSCULUS IN LAKE POBŁĘDZIE, USING POLYMODAL LENGTH FREQUENCY DISTRIBUTION ANALYSIS

Knowledge and Management of Aquatic Ecosystems, 2006
This study estimated the rate of growth of Pacifastacus leniusculus using the sizefrequency data analysis in Lake Pobłędzie NE Poland. A sample of 1,342 individuals (645 males and 697 females) was collected with baited traps in late September 2002.

Consequences for lotic ecosystems of invasion by signal crayfish [PDF]

, 2012
PhDNon-native invasive species are major drivers of biodiversity loss and ecosystemlevel modification. The signal crayfish (Pacifastacus leniusculus) is a highly successful invasive species and demonstrates traits often seen in keystone species ...

Trypsin from Pacifastacus leniusculus hepatopancreas: Purification and cDNA cloning of the synthesized zymogen

, 1999
Trypsin was purified from crayfish, Pacifastacus leniusculus, hepatopancreas, and the gene that encoded this enzyme was cloned from a hepatopancreas cDNA library.

Predation preference of signal crayfish (Pacifastacus leniusculus) on native and invasive bivalve species [PDF]

, 2022
Predatory, non-native fauna can influence biodiversity and trophic dynamics in invaded ecosystems. Signal crayfish (Pacifastacus leniusculus) are a highly successful invader, which have altered freshwater benthic communities, including bivalve ...

River bank burrowing is innate in native and invasive signal crayfish (Pacifastacus leniusculus) and is driven by biotic and abiotic cues [PDF]

, 2023
The behavior of animals can change when they become invasive. Whilst many species demonstrate exaggerations of existing behaviors, signal crayfish (Pacifastacus leniusculus) display a novel burrowing activity in some invaded rivers.

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 ...
