Aphanomyces astaci PsI-genotype isolates from different Finnish signal crayfish stocks show variation in their virulence but still kill fast

Knowledge and Management of Aquatic Ecosystems, 2013
We detected significant virulence differences among five tested (PsI-Puujärvi, PsI-Pyhäjärvi, PsI-Kukkia, PsI-Saimaa I and PsI-Saimaa II) PsI-genotype crayfish plague (Aphanomyces astaci) isolates against lake Mikitänjärvi noble ...

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

Freshwater Mussel Anodonta cygnea Reduces Concentration, Germination Rate and Infectivity of Pathogenic Oomycete Saprolegnia spp. Spores

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Saprolegniosis, also known as water mould, is a lethal disease caused by Saprolegnia oomycetes that threatens freshwater animals including fish, amphibians, and crustaceans, as well as aquaculture. It causes biodiversity loss and population declines, including those of endangered fishes.

Aphanomyces astaci isolate from latently infected stone crayfish (Austropotamobius torrentium) population is virulent

, 2017
Aphanomyces astaci infection is the cause of crayfish plague in European crayfish. Here the virulence of an A. astaci As strain isolated from apparently healthy stone crayfish (Austropotamobius torrentium) from Slovenia was compared to that of the Psl ...

Impact of the Highly Invasive Signal Crayfish (Pacifastacus leniusculus) on Freshwater Macroinvertebrate Communities

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Invasive non‐native species threaten freshwater ecosystems, disrupting the functioning and structure of the food chain and potentially leading to biodiversity loss. As omnivores, crayfish can modify their environment, directly affecting organisms such as macroinvertebrates.
