Exponential increase of signal crayfish in running waters in Sweden – due to illegal introductions?

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
Sweden has only one indigenous species of crayfish, the noble crayfish (Astacus astacus, Fabricius). There has been a steady decline of noble crayfish populations in Sweden since 1907, mainly due to the crayfish plague.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

THE DISPERSION OF THE APHANOMYCES ASTACI-CARRIER PACIFASTACUS LENIUSCULUS BY HUMANS REPRESENTS THE MAIN CAUSE OF DISAPPEARANCE OF THE INDIGENOUS CRAYFISH AUSTROPOTAMOBIUS PALLIPES IN NAVARRA

open access: yesKnowledge and Management of Aquatic Ecosystems, 2006
The tendency of population decline of the indigenous crayfish, Austropotamobius pallipes, in Navarra was reduced by the implementation of a plan of restoration in 1996. Recently, a new drop in population numbers has been noticed.

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.

Review of Dam Effects on Native and Invasive Crayfishes Illustrates Complex Choices for Conservation Planning

open access: yesFrontiers in Ecology and Evolution, 2021
Dams are among the most prevalent and extreme alterations humans have perpetrated on fluvial systems. The dramatic physical and biological changes caused by dams have been synthesized for many aquatic faunal groups, but not for crayfishes.

Status of the white-clawed crayfish, Austropotamobius pallipes (Lereboullet, 1858), in Spain : distribution and legislation

open access: yesKnowledge and Management of Aquatic Ecosystems, 2000
The white-clawed crayfish, Austropotamobius pallipes, is the only native species of freshwater crayfish in Spain. This species sustained a first-magnitude inland fishery up to the end of 1970's, when the crayfish plague struck the Spanish waters.

Predatory decapods for biological control of pest snails: Ecological, behavioural and mechanical aspects

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
A food‐choice experiment illustrating that monosex decapods can serve as efficient biological control agents against parasite‐transmitting snails in aquaculture systems. We presented prawns and crayfish to four pest snail species with varying shell characteristics and quantified their predation preferences and traits. We show that the force required to

Molecular Characterisation of Endangered White‐Clawed Crayfish Populations in Southern Switzerland

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 3, March 2026.
ABSTRACT This study investigates the phylogeography of the endangered European White‐Clawed Crayfish (WCC) Austropotamobius pallipes species complex in the main tributaries of the Po River basin in southern Switzerland and northern Italy, a diversity hotspot for this species.

LACK OF SPECIFICITY OF THE MOLECULAR DIAGNOSTIC METHOD FOR IDENTIFICATION OF APHANOMYCES ASTACI

open access: yesKnowledge and Management of Aquatic Ecosystems, 2007
A recent PCR-test developed for identification of Aphanomyces astaci, the organism responsible for crayfish plague, provided false positives for Aphanomyces frigidophilus, Aphanomyces repetans, and some Saprolegnia spp. Real-time PCR showed that with the
