Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, Volume 46, Issue 10, August 2026.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

Two indigenous European crayfish under threat – how can we retain them in aquatic ecosystems for the future?

Knowledge and Management of Aquatic Ecosystems, 2011
Indigenous crayfish species (ICS) are under threat in Europe; due to competition from invasive non-indigenous crayfish species (NICS) from crayfish plague, which is carried by introduced American crayfish, and habitat degradation.

First record of the stone crayfish in the Romanian lowlands

Knowledge and Management of Aquatic Ecosystems, 2021
The stone crayfish is a native European freshwater species with significant population declines caused by anthropogenic pressure onto its habitats, climate change and spreading of non-indigenous invasive crayfish and their pathogens (e.g., Aphanomyces ...

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

Journal 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 ...

Environmental DNA as a Detection and Quantitative Tool for Brown Bullhead Catfish (Ameiurus nebulosus): A Comparison With Conventional Netting

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Multiple environmental DNA (eDNA) methods were compared with each other and with fyke netting for detecting invasive brown bullhead catfish. eDNA sampling combined with catfish‐specific metabarcoding provides sensitive detection and effectively complements traditional netting for biosecurity.

LONG TERM STUDY OF COMPETITION BETWEEN TWO CO-OCCURRING CRAYFISH SPECIES, THE NATIVE ASTACUS ASTACUS L. AND THE INTRODUCED PACIFASTACUS LENIUSCULUS DANA, IN A FINNISH LAKE.

Knowledge and Management of Aquatic Ecosystems, 2001
Since 1893, crayfish plague, Aphanomyces astaci Schikora, has devastated Finland’s most productive populations of the native noble crayfish, Astacus astacus, causing great losses to once very valuable fisheries and exports.

The spread of non‐native species

Biological 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.

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

Ecological 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

Epidemiology of crayfish plague [PDF]

, 2016
Crayfish plague is a severe disease of European crayfish species and has rendered the indigenous crayfish populations vulnerable, endangered or even extinct in the most of Europe. Crayfish plague is caused by an oomycete Aphanomyces astaci, a fungal-like
