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.

Spring temperature drives phenotypic selection on plasticity of flowering time

In seasonal environments, a high responsiveness of development to increasing temperatures in spring can infer benefits terms longer growing season, but also costs an increased risk facing unfavourable weather conditions. Still, we know little about how climatic conditions influence the optimal plastic response. Using 22 years field observations for perennial forest herb Lathyrus vernus, assessed phenotypic selection on among-individual variation reaction norms flowering time temperature, and examined if among-year plasticity was associated with temperature We found significant mean plasticity, that plants flowered earlier had more time. Selection favoured individuals lower thermal Less were strongly colder springs, indicating influenced plasticity. Our results show be linked conditions, illustrate understand predict evolutionary responses organisms changing environmental
