Impact of future climate on radial growth of four major boreal tree species in the Eastern Canadian boreal forest.

Immediate phenotypic variation and the lagged effect of evolutionary adaptation to climate change appear to be two key processes in tree responses to climate warming. This study examines these components in two types of growth models for predicting the 2010-2099 diameter growth change of four major...
