Subtle precipitation differences yield adaptive adjustments in the mesic Nothofagus dombeyi

Climate change is impacting on natural systems and forests worldwide have suffered from massive mortality due to extreme droughts. That is the case of mesic Nothofagus dombeyi forests of northern Patagonia, whereas no climate-driven mortality was recorded towards drier areas. The aim was to examine population differences in relation to a small precipitation gradient at morphological, physiological, and genetic scales. Adaptive differences...
