Ecological responses to climate crisis reveal body size dynamics in marine bivalves, indicating unique evolutionary patterns.

This research investigates the body size changes of marine bivalves during the Permo-Triassic climate crisis.
Analyzed specimen-level data from marine bivalves in the Dolomites, Italy.
Utilized high-resolution records spanning the Permian-Triassic climate crisis.
Examined body size changes at both species and genus levels.
Significant turnover of species with newly evolved species being typically smaller.
Three surviving species did not show significant body size changes.
Observed genus-level size recovery driven by existing and newly evolved larger species.

Foster et al. (2026) studied this question.
