An Emergent Seafood Nationalism Takes Hold in the United States

Fish and Fisheries, Volume 27, Issue 4, Page 1047-1055, July 2026.
ABSTRACT This paper introduces the concept of ‘seafood nationalism’ to describe how, since 2024–2025, the United States increasingly uses tariffs, trade remedies, food safety enforcement and origin‐based rules to favour American seafood over foreign products.

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.

Effect of mesh size on baited trap catch composition for noble crayfish (Astacus Astacus)

Knowledge and Management of Aquatic Ecosystems, 2014
Minimum size is a common management regulation in noble crayfish (Astacus astacus) fisheries. The most used catching method baited traps, catch crayfish down to 50 mm total length (TL).

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

INTERACTION BETWEEN NATIVE AND ALIEN SPECIES OF CRAYFISH IN AUSTRIA: CASE STUDIES

Knowledge and Management of Aquatic Ecosystems, 2002
In Austria, three indigenous crayfish species occur: the noble crayfish (Astacus astacus), the stone crayfish (Austropotamobius torrentium), and the white-clawed crayfish (Austropotamobius pallipes).

Warming and latitude shape the non-consumptive effects of native and invasive alien crayfish predators on damselfly prey [PDF]

NeoBiota
There is increasing concern that the effects of biological invasions may be magnified by other human-induced global changes. Here, we compare the non-consumptive effects imposed by invasive vs.

Disease‐associated mortality drives reduction in Yukon River Chinook salmon escapement: A novel method for quantifying the negative impacts of ‘misfit’ parasites to improve fisheries management

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Alaska Department of Fish and Game is implementing an annual monitoring program at the mouth of the Yukon River where our model will estimate the proportion of Chinook salmon at risk from parasite‐induced mortality to inform annual management. Moreover, the model is broadly applicable to other fungal‐like and myxozoan parasites of conservation concern,

Interplay of Diet, Heat Stress, and the Microbiome Shapes Health and Escape Behaviour in Amphibian Larvae

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Diet and temperature jointly shape the gut microbiome and host performance in amphibian larvae. In a multifactorial experiment with Rana temporaria, diet quality, rearing temperature, and heatwave exposure altered microbial communities and predicted metabolic pathways, while host health remained largely stable, suggesting microbiome plasticity and ...

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

Animal 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 ...
