Subtle ecological effects of the invasive signal crayfish (Pacifastacus leniusculus) on Iberian fish communities

Biological Invasions
The introduction of non-native species can disrupt the structure of communities and affect the functioning of freshwater ecosystems, disturbing various taxonomic groups, including fish.

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.

Invasive dynamics of the signal crayfish Pacifastacus leniusculus in a protected area

Hydrobiologia
Invasive species have been drivers of biodiversity loss and functional changes in aquatic ecosystems, including in protected areas. Therefore, monitoring population invasion dynamics and biological traits is fundamental to better understand their ...

Signatures of Wild Animal Life in Earth's Landscapes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Animals shape Earth surface processes and landforms by displacing Earth surface materials and by making them more or less susceptible to geophysical processes. Despite increased recognition of the global significance of animal landscape “signatures”, analysis of their magnitude and generality has not been possible until now.

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.
