The impact of streetlights on an aquatic invasive species: artificial light at night alters signal crayfish behaviour [PDF]

, 2016
Artificial light at night (ALAN) can significantly alter the behaviour, communication and orientation of animals, and will potentially interact with other stressors to affect biodiversity.

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.

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.

Invasion biology in non-free-living species: interactions between abiotic (climatic) and biotic (host availability) factors in geographical space in crayfish commensals (Ostracoda, Entocytheridae) [PDF]

, 2013
In invasion processes, both abiotic and biotic factors are considered essential, but the latter are usually disregarded when modeling the potential spread of exotic species.

Climate change threatens unique genetic diversity within the Balkan biodiversity hotspot – The case of the endangered stone crayfish

Global Ecology and Conservation, 2022
The stone crayfish Austropotamobius torrentium is globally endangered due to anthropogenic pressure on its habitats, climate change and the invasive crayfish species, particularly the signal crayfish Pacifastacus leniusculus.

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.

Artificial light at night and invasive signal crayfish alter aquatic‐terrestrial food webs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Resource flows across aquatic‐terrestrial boundaries are increasingly affected by multiple stressors, such as artificial light at night (ALAN) and aquatic invasive species, which can alter the availability of resources for consumers.

Host shift to non-native species or ecological dead end? Endangered branchiobdellidans (Annelida: Clitellata) found on introduced Signal Crayfish in Japan

Knowledge and Management of Aquatic Ecosystems
Symbionts, including parasites, are usually small and thus have been overlooked for their existence and scientific research. In the context of biological invasion, host shifts between native and non-native species occur. Since symbionts often affect host

LONG TERM STUDY OF COMPETITION BETWEEN TWO CO-OCCURRING CRAYFISH SPECIES, THE NATIVE ASTACUS ASTACUS L. AND THE INTRODUCED PACIFASTACUS LENIUSCULUS DANA, IN A FINNISH LAKE.

Knowledge and Management of Aquatic Ecosystems, 2001
Since 1893, crayfish plague, Aphanomyces astaci Schikora, has devastated Finland’s most productive populations of the native noble crayfish, Astacus astacus, causing great losses to once very valuable fisheries and exports.

Evaluating the Efficacy of Approaches to Control Invasive Populations: A Conceptual Model Development for the Signal Crayfish

Ecologies, 2022
Invasive crayfish are among the major threats to freshwater ecosystems, with the signal crayfish, Pacifastacus leniusculus, being one of the most successful crayfish invaders in Europe.
