AbstractTree-ring science is experiencing an important paradigm shift. Historically defined as an empirical science based on the study of statistical relationships between climate and growth, studies now choose to focus on the mechanistic / deterministic modelling of such relationships. This new approach consists in developing and improving ecophysiological models (also referred to as 'virtual trees'). Such virtual trees form an ensemble of rules and equations that allow for the dynamical simulation of tree response to hydro-climate variations. This new approach offers several advantages for future tree ring research: it should improve our capacity to predict tree response in the face of climate change and should also help producing reconstructions that are in line with processes controlling growth. This chapter aims at demonstrating that this paradigm change can be beneficial to tree ring studies conducted in the Quebec-Labrador region.
