Overview

Systematic review reveals how heat stress alters gut microbiota and immune responses in freshwater fish, suggesting implications for climate change resilience.

Key Points

To synthesize knowledge on the effects of elevated temperatures on gut microbiota and immune responses in wild freshwater fish.
Conducted a systematic literature search across Web of Science, PubMed, Scopus, and Google Scholar.
Reviewed studies linking thermal stress to gut microbial communities and immune modulation.
Explored epigenetic mechanisms influencing immune gene expression in response to thermal stress.
Thermal stress reduces microbial diversity, particularly affecting beneficial phyla such as Firmicutes and Actinobacteria.
Increased prevalence of opportunistic pathogens observed under heat stress conditions.
Evidence suggests that DNA methylation may play a role in modulating immune responses to environmental stressors.
