Unpacking climate effects on boreal tree growth: an analysis of tree-ring widths across temperature and soil moisture gradients
Abstract. The effect of climate change on tree growth in boreal forests is likely mediated by local climate conditions and species-specific responses that vary according to differences in traits. Here...
