title: Climatic signal of earlywood vessels of oak on a maritime site.
abstract: Earlywood vessel lumen areas were measured in 72 consecutive tree rings in wood cores from oak (Quercus robur L.) trees in a maritime woodland. This anatomical time series was statistically correlated with climate data for the same time span. There was a strong dependence of earlywood vessel lumen area on rainfall between February and April, which reflects the role of water availability in vessel ontogeny. By inversion, earlywood vessel lumen areas can be used as a proxy to reconstruct spring precipitation beyond the archived weather records. Such information may be of value in the context of climate change.
