Evolutionary constraints on thermal performance

How genetic correlations among thermal performance traits limit adaptation to warmer and more variable climates.

← All research

Can organisms evolve fast enough to keep up with changing climates? Other Theoretical models

The question

Thermal performance curves are described by traits such as the thermal optimum and critical thermal limits. If these traits are genetically correlated, the range of curve shapes a population can evolve is constrained.

Approach

Individual-based simulations of populations evolving under warming and increasingly variable climates, with and without genetic correlations among thermal traits.
