Short summary
By comparing the cork oak tree vegetative phenology in two contrasting precipitation years in a Mediterranean ecosystem, we showed the critical role of water availability in extending the length of the growing season and determining tree growth. The observed higher transfer of nitrogen from senescent to green leaves in response to drought might compensate for the limited nitrogen uptake by the roots. Our results improve our understanding of the ecosystem's responses to climate change.
