Seasonality of gastrolith and chitin matrix possession of wild red swamp crayfish.

, 2015
Crayfish have “gastroliths” in which calcium is deposited transiently during the molt cycle from the cuticle. In red swamp crayfish, amorphous calcium carbonate is embedded in an organic matrix composed mainly of chitin.

Effect of Liquid Nitrogen Freezing on Maintaining the Quality of Crayfish During Freeze–Thaw Cycles: Muscle Structure and Myofibrillar Proteins Properties

Foods
The quality of frozen crayfish (Procambarus clarkii) is challenged by freeze–thaw (FT) cycles during storage. The effect of freezing methods on the quality of crayfish during FT cycles was investigated by comparing physicochemical properties ...

Allochthonous chemical cues drive predation by a top carnivore

Functional Ecology, Volume 40, Issue 6, Page 1698-1708, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Identifying the mechanisms by which mobile predators detect and select prey remains a central challenge in sensory biology and functional ecology. This study provides the first direct evidence that chemical cues associated with allochthonous organic matter (e.g.

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

Journal of Animal Ecology, Volume 95, Issue 6, Page 989-1001, June 2026.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

Mass Mortality of Cherax quadricarinatus (Von Martens, 1868) reared in Sicily (Italy): Crayfish Plague Introduced in an Intensive Farming Freshwater Crayfish

, 2014
An episode of mortality in farmed redclaw crayfish, Cherax quadricarinatus, reared in Sicily, is described. Histological and PCR methods were used to identify the oomycetes, Aphanomyces astaci, as the causative agent of the disease.

Rewilding beyond the wilderness: Beavers can restore stream biodiversity from urban to agricultural to natural landscapes

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our findings show that beaver‐engineering significantly enhances local biodiversity across aquatic and terrestrial ecosystems, even at sites with high land‐use intensity. Hence, beavers can effectively restore stream biodiversity across a range of urban to agricultural to natural ecosystems.

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 ...
