Résumé
Fire is a natural disturbance in many biomes, but altered fire regimes are a global change threat impacting both fire-sensitive and fire-dependent ecosystems. Novel fire regimes now affect many ecosystems, and as the main fuels of wildfires, plants feature prominently in our understanding of fire as part of a changing world. This issue of the American Journal of Botany showcases studies using trait-based approaches to understand fire–plant dynamics from evolutionary, ecological, organismal, physiological, fire management, and conservation perspectives.
