title: Data from: High metabolic sensitivity to hot drought in two declining pine species with constrained physiology

description: This dataset includes metabolic data and different functional traits of
 two different pine species including trees in decline and healthy trees.
 One dataset includes all different shared metabolites identified in the
 two species and individuals sampled under peak drought stress. The second
 dataset includes functional traits from gas exchange, hydraulics and
 osmotic relationships. These functional traits were assessed during two
 study years with contrasting summer drought.
