Key message Provenances show a high phenotypic plasticity and the ability to grow beyond the cold treeline. Local is best can still be applied. Abstract Boreal forests situated in high latitudes face heightened susceptibility to climate extremes and global warming. Understanding the relative influence of adaptation mechanisms like phenotypic plasticity or local adaptation on key traits is crucial to better understand and proje...

Key message Climate-growth correlations are non-stationary among all size classes, and large trees are becoming sensitive to August and September drought conditions in the year preceding growth during the last decades. Abstract Understanding tree growth and forest dynamics under climate change is paramount to predict changes in carbon cycling, forest development, and ecosystem services. At temperature limited sites, such as al...

Tree growth is a multifaceted process influenced by various factors at different spatial and temporal scales, including intrinsic tree traits and environmental conditions. Climate factors have a significant impact on tree growth dynamics, while geological controls can also play a crucial role. However, our understanding of the interplay between these factors concerning tree growth is currently limited. This study focuses on No...
