STATUS OF FRESHWATER CRAYFISH IN LATVIA

Knowledge and Management of Aquatic Ecosystems, 2005
There are three crayfish species present in Latvia: the European noble crayfish (Astacus astacus), the narrow-clawed crayfish (Astacus leptodactylus), and the North-American signal crayfish (Pacifastacus leniusculus) species. Probably only noble crayfish

Trophic plasticity and invasive success: dynamic feeding strategies of the signal crayfish in Croatian rivers

Journal of Freshwater Ecology
The invasive signal crayfish (Pacifastacus leniusculus), a species of high concern in European freshwaters, represents a substantial threat to native crayfish species and freshwater ecosystems.

SHELTER COMPETITION BETWEEN TWO INVASIVE CRAYFISH SPECIES: A LABORATORY STUDY

Knowledge and Management of Aquatic Ecosystems, 2006
Alien crayfishes represent a common threat to aquatic ecosystems. Their spread in Europe is leading to more frequent contacts between different invasive species populations. Shelter can be an important factor in the resulting interactions.

Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology [PDF]

NeoBiota
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused on the NCE of predator-induced stress from one native

SPECIES OF BRANCHIOBDELLIDAE (ANNELIDA) ON FRESHWATER CRAYFISH IN SOUTH TYROL (NORTHERN ITALY)

Knowledge and Management of Aquatic Ecosystems, 2002
Twenty-eight freshwater crayfish were collected from 8 streams and one small lake in the province of South Tyrol (North Italy) from autumn 1999 to spring 2001, in order to investigate the presence of branchiobdellidans.

The ‘Pritchard Trap’: A novel quantitative survey method for crayfish

Ecological Solutions and Evidence, 2021
As crayfish invasions continue to threaten native freshwater biota, a detailed understanding of crayfish distribution and population structure becomes imperative. Nonetheless, most current survey methods provide inadequate demographic data.

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 ...

Personality, density and habitat drive the dispersal of invasive crayfish

Scientific Reports, 2022
There is increasing evidence that personality traits may drive dispersal patterns of animals, including invasive species. We investigated, using the widespread signal crayfish Pacifastacus leniusculus as a model invasive species, whether effects of ...
