Longstanding eco-evolutionary theories are tested using shotgun metagenomic data from the human gut microbiome, showing links between community diversity and the evolutionary trajectory of a focal species within the community.
Secondary metabolites rocaglates produced by plants lead to a plant‒fungus tug-of-war, utilizing unique amino acid substitutions in eIF4A, a target of the compounds.
Mobility across ecological contexts and continents is more important to describe the worldwide spread of bacterial resistance to aminoglycosides (a family of antibiotics), than the consumption of aminoglycosides itself.
Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.
Environmental DNA from highly standardized leaf sample time series suggests no localized species losses, but biotic turnover and homogenization, as main drivers of forest insect decline.
Evolutionary changes in cuticular hydrocarbons, a lipid layer on the insect epicuticle, underlie the evolution of desiccation resistance in Drosophila species.
Species and genetic diversity promote tree community productivity by increasing functional diversity and reducing herbivore damage and soil fungal diversity.
