Diapause polymorphisms shape insect life cycles, affecting their responses to seasonal environmental fluctuations. In the spruce bark beetle Ips typographus, diapause phenotypes, classified as facult...

Symbiotic bacteria can have exceedingly small genomes. This study finds that ancient bacterial symbionts of planthoppers have repeatedly evolved the smallest known genomes, losing most biosynthetic fu...

Warming oceans and evolution make fish less likely to be on the menu

Global warming is altering the fisheries that underpin food security, but projections of these impacts generally exclude evolutionary processes. We describe a model that forecasts how fish will adapt ...

Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group...

Organisms vary in their nitrogen and phosphorus content, shaping ecological and evolutionary processes. This study shows that nitrogen deposition is a consistent global factor associated with plant an...

While microbial symbioses are fundamental to the nutrition of many animal groups, current paradigms focus on symbiont functions at the host individ...
