Behavior and Physiology Outpace Form When Linking Traits to Ecological Responses Within Populations: A Meta-Analysis

Thibaut Rota, Allan Raffard, Iris Lang…·Régis Céréghino

This study meta-analyzes over a thousand effect sizes to show that trait variability within populations influences ecological responses more strongly for physiology and behavior than morphology.

Experimental metal contamination reduces gut microbiota diversity and alters its composition and function in wild-caught fish

Quentin Petitjean, Séverine Jean, Margarita GRANADA…·Joël White

This study shows that metal contamination reduces gut microbiota diversity and alters its composition and function in wild fish, with no interaction with an immune challenge.
