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.

First detection of Aphanomyces astaci and its potential responsibility for mass mortalities of Pontastacus (Astacus) leptodactylus in Greek lakes

Journal of Biological Research - Thessaloniki
Aphanomyces astaci is a pathogen categorized among the 100 worst invasive alien species, responsible for the crayfish plague disease. In the past, many disease outbreaks devastated native European crayfish populations.

A STUDY ON THE POSSIBLE EFFECT OF TWO CRAYFISH SPECIES ON EPILITHIC ALGAE IN A MOUNTAIN STREAM FROM CENTRAL SPAIN

Knowledge and Management of Aquatic Ecosystems, 2006
The effects on epilithic algae of increasing densities of two crayfish species, Austropotamobius italicus and Pacifastacus leniusculus, the latter recently introduced in Spain, have been monitored using riverine enclosures, within a large experimental ...

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.

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.

The mycobiome of a successful crayfish invader and its changes along the environmental gradient

Animal Microbiome, 2023
Background The microbiome plays an important role in biological invasions, since it affects various interactions between host and environment. However, most studies focus on the bacteriome, insufficiently addressing other components of the microbiome ...

Transglutaminase activity in the hematopoietic tissue of a crustacean, Pacifastacus leniusculus, importance in hemocyte homeostasis [PDF]

BMC Immunology, 2008
Abstract Background Transglutaminases (TGases) form a group of enzymes that have many different substrates and among the most well known are fibrin for Factor XIIIa and the clotting protein in crustaceans. We also found that TGase is an abundant protein in the hematopoietic tissue (Hpt) cells of crayfish and hence we ...

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.

RELATIONSHIPS BETWEEN CHANGES IN HABITAT CONDITIONS AND POPULATION DENSITY OF AN INTRODUCED POPULATION OF SIGNAL CRAYFISH (PACIFASTACUS LENIUSCULUS IN A FLUVIAL SYSTEM.

Knowledge and Management of Aquatic Ecosystems, 2001
After the disappearance of the native crayfish in many rivers in Biscay, Basque Country, Spain, the signal crayfish Pacifastacus leniusculus was introduced in the main fluvial stretches and several breeding populations have established.
