Assessment of the Population Status of Globally Threatened Crayfish Astacus astacus and Austropotamobius torrentium in the Lakes Prespa, Ohrid and Rivers of the Shebenik-Jabllanicë National Park, Albania

open access: yesAlbanian Journal of Natural and Technical Sciences
Despite being internationally recognized as threatened, there are no comprehensive studies on the crayfish species Astacus astacus and Austropotamobius torrentium in Albanian freshwaters.

Beyond Niche Overlap: Axis‐Specific Reorganisation of Environmental Space in Freshwater Crayfish Invasions

open access: yesJournal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Understanding whether invasive species retain or shift their ecological niches has relied on scalar overlap metrics that quantify the magnitude of niche change but not its structure. Here, we test whether biological invasions involve a reorganisation of the environmental axes along which native and invasive ranges are differentiated, and ...

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

open access: yes, 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

HIGH DISPERSAL ABILITY OF AUSTROPOTAMOBIUS PALLIPES REVEALED BY MICROSATELLITE MARKERS IN A FRENCH BROOK

open access: yesKnowledge and Management of Aquatic Ecosystems, 2002
The genetic structure of a large population of the white-clawed crayfish Austropotamobius pallipes was assessed with five microsatellite markers by sampling six sites along its extent.

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

PRELIMINARY OBSERVATION OF OCCASIONAL MORTALITY IN THE POPULATION OF FRESHWATER CRAYFISH IN THE PICOS DE EUROPA (ASTURIAS, SPAIN)

open access: yesKnowledge and Management of Aquatic Ecosystems, 2002
Factors associated with mortality in a population of Austropotamobius italicus, formerly A. pallipes lusitanicus, were monitored during two years in the Natural Park of Picos de Europa. Dead crayfish were submitted to the laboratory for analysis. No mass

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 274-284, June 2026.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

HABITAT PREFERENCE OF DIFFERENT SIZE CLASSES OF AUSTROPOTAMOBIUS PALLIPES IN AN IRISH RIVER

open access: yesKnowledge and Management of Aquatic Ecosystems, 2003
Juvenile and immature crayfish are more difficult to find than adults and in consequence rather little is known about their habitat preferences. Smaller crayfish are able to inhabit different areas within the stream compared to adult crayfish.

Overcoming taxonomic anxiety in conservation: A roadmap from the idle crayfish case

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
Abstract Advances in taxonomy often uncover cryptic species nested within already protected taxa, raising concerns about the continuity of legal safeguards. While newly described species are not necessarily disconnected from existing protections, often being treated administratively as part of the original species complex, formal legislative updates ...

Induction of ovarian maturation by means of dietary hormonal treatment in Austropotamobius pallipes

open access: yesItalian Journal of Animal Science, 2010
The freshwater crayfish Austropotamobius pallipes is an annual species with low fecundity and a long embryonic development. Restocking programmes for this species have recently been prompted in many countries in Europe because of its ecological ...
