Divergent Thermal Reaction Norms of the Spontaneous Mutation Rate Among Populations of <i>Chironomus riparius</i>

2026-04-09

Abstract excerpt

The germline mutation rate µ is a fundamental evolutionary parameter, yet its plasticity in response to environmental factors, particularly temperature, remains poorly understood. While often modeled as a species-specific constant, we tested whether µ evolves in response to local thermal regimes. Using whole-genome sequencing of mutation accumulation lines in the non-biting midge Chironomus riparius , we demonstr...
