Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches

Abstract

The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation differ from those of most temperate regions. Furthermore, the findings guide modellers by quantifying the relative importance of different types of acclimation responses. Physiological acclimation generally dampened instantaneous responses and it is critical to incorporate these responses into vegetation models to improve projections of atmosphere-biosphere interactions of boreal regions in a changing climate.
