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

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

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.

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

Functional Ecology, Volume 40, Issue 6, Page 1740-1754, June 2026.
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.

Impacts of signal crayfish on stream fishes [PDF]

, 2013
Invasive species cause biodiversity and economic loss globally. Invasive crayfish have a wide range of effects as a result of their high densities and biomass, feeding at multiple trophic levels, aggressive competition for shelter and ecosystem ...

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.

Interactive effects between burrowing crayfish and flow conditions increase riverbank erosion: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Biological and geomorphic effects have been treated independently in fluvial geomorphology. Flume experiments with burrowing crayfish show that interactions between these drivers do more geomorphic work than the sum of their maximum independent parts combined, meaning total biogeomorphic effects to rivers are likely underestimated.

Spatial ecology of white-clawed crayfish Austropotamobius pallipes and signal crayfish Pacifastacus leniusculus in upland rivers, Northern England [PDF]

, 2004
The American signal crayfish Pacifastacus lernusculus, an invasive species widely introduced throughout Europe, is a major threat to native European crayfish species and is causing increasing concern because of its wide impact on aquatic ecosystems. This

New data on the introduction of the invasive signal crayfish Pacifastacus leniusculus (Dana, 1852) (Crustacea, Decapoda) and ectosymbiont branchiobdellidans (Annelida, Clitellata) in NW Iberian Peninsula

, 2017
The non-native signal crayfish Pacifastacus leniusculus (Dana, 1852) has successfully been established in many catchments of Europe, causing detrimental impacts on both native flora and fauna.

The role of mitophagy during hematopoiesis in an invertebrate , Pacifastacus leniusculus

The Journal of Immunology
Abstract Freshwater crayfish as most aquatic crustaceans live for up to 20–30 years on the bottom of lakes and rivers, constantly exposed to millions of microorganisms. Consequently, they must have an effective immune system to combat and eliminate pathogens.
