Native European branchiobdellids on non-native crayfishes: Report from the Czech Republic

Journal of Limnology, 2017
Invasive alien species present a global threat to biodiversity, particularly where pathogens and symbionts are involved. Non-native crayfish species can increase their impact on the host ecosystem through introductions of symbiotic fauna. Conversely, non-

Distribution of Non-Indigenous Crayfish Species in Estonia and Their Impacts on Noble Crayfish (Astacus astacus L.) Populations

Diversity, 2023
Invasive non-indigenous crayfish species (NICS) are a major threat to the existence of native crayfish populations in European freshwater ecosystems. The discovery of signal crayfish Pacifastacus leniusculus, marbled crayfish Procambarus virginalis, and ...

Decoupled conservatism of Grinnellian and Eltonian niches in an invasive arthropod

Ecosphere, 2010
Whether a species niche is conserved or shifts across space and time is a question of heightened interest in ecology and evolution. Considerable scientific inquiry into this topic has used invasive species to evaluate conservatism of the Grinnellian ...

CRAYFISH MANAGEMENT FOR SWISS WATERS

Knowledge and Management of Aquatic Ecosystems, 2006
Seven species of crayfish are present in Swiss waters: three native ones (Astacus astacus, Austropotamobius pallipes, Austropotamobius torrentium) and four exotic ones (Astacus leptodactylus, Orconectes limosus, Pacifastacus leniusculus, Procambarus ...

Eradication attempt for an early detected invasive crayfish: the case of Pacifastacus leniusculus (Decapoda, Astacidae) in the Clitunno River (central Italy) [PDF]

NeoBiota
The signal crayfish Pacifastacus leniusculus (Dana, 1852) is one of the most ecologically impactful decapod crustaceans introduced in Europe. As a species of Union concern, early detection and rapid eradication measures are required to prevent its ...

REDUCING THE THREAT TO CONTROL INVASIVE SIGNAL CRAYFISH REDUCING: THE POTENTIAL USE OF PHEROMONES

Knowledge and Management of Aquatic Ecosystems, 2003
The need for an effective method of controlling invasive species of crayfish is of utmost importance given the plight of Europe’s native crayfish species. Many techniques have been applied to the growing problem with little success.

Processing of an Antibacterial Peptide from Hemocyanin of the Freshwater Crayfish Pacifastacus leniusculus [PDF]

Journal of Biological Chemistry, 2003
An antibacterial peptide with 16 amino acid residues was found in plasma of the freshwater crayfish, Pacifastacus leniusculus. This peptide, designated astacidin 1, was purified by cation-exchange column chromatography and reverse-phase high performance liquid chromatography.

Environmental DNA‐based methods detect the invasion front of an advancing signal crayfish population

Environmental DNA, 2022
Aquatic invasive species, such as the signal crayfish (Pacifastacus leniusculus), present a major threat to freshwater ecosystems. However, these species can be challenging to detect in recently invaded habitats.

Proteomic profiling of the signal crayfish Pacifastacus leniusculus egg and spermatophore

Animal Reproduction Science, 2014
Proteins of the signal crayfish Pacifastacus leniusculus egg and spermatophore were identified using in-gel digestion, mass spectrometry, and Mascot search. Forty-one and one-hundred-fifty proteins were identified in egg and spermatophore, respectively.
