Abstract Genetic differentiation in traits is assumed to frequently occur response divergent natural selection. For example, developmental might respond differences climate. However, little known about when and at which spatial scales environmental lead genetic differentiation, what extent there also trait plasticity. Using a crossing design greenhouse heating experiment, we investigated thermal sensitivity of flowering time perennial herb along small-scale gradients geothermal soil Iceland. We found additive variation both plasticity time. median date individuals showed counter-gradient pattern; being earlier higher temperatures, while given temperature originating from warmer soils flowered later than colder soils. no corresponding pattern for plasticity, suggesting that phenology has occurred through changes means rather Findings such as these, identifying an gradient are key understand how can drive the process local adaptation, predict responses future changes.
