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

open access: yesFreshwater 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.

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

First record of Astathelohania contejeani (Henneguy, 1892) in the narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823) from Belarus

open access: yesOceanological and Hydrobiological Studies
Porcelain disease, caused by the parasite Astathelohania contejeani, is a fatal disease for freshwater crayfish. Previously published data provide information on the occurrence of A. contejeani in various crayfish species. However, its prevalence in host

Combining thermal and hydric constraints for spatially predicting the activity suitability of Neotropical Leptodactylid frogs

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Amphibians balance their thermal and water budgets depending on their physiological state and the physical environment, with both factors capable of constraining activity. Most mechanistic assessments emphasize thermal over water constraints, potentially missing important aspects of amphibian ecophysiological patterns.

Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

Stress Nutrition in Aquatic Animals: From Definition to Practice

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
