TL;DR: TRY as discussed by the authors is a global database of plant traits, including morphological, anatomical, physiological, biochemical and phenological characteristics of plants and their organs, which can be used for a wide range of research from evolutionary biology, community and functional ecology to biogeography.

TL;DR: The extent of the trait data compiled in TRY is evaluated and emerging patterns of data coverage and representativeness are analyzed to conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements.

TL;DR: In this paper, the authors reconcile two long-standing theories of stomatal conductance, i.e., the theoretical argument that stomata should act to minimize the amount of water used per unit carbon gained, and the empirical approach, which is most commonly used in vegetation models, is phenomenological, based on experimental observations of Stomatal behaviour in response to environmental conditions.

TL;DR: This work focuses on the current understanding of tree hydraulic performance under drought, the identification of physiological thresholds that precipitate mortality and the mechanisms of recovery after drought, and the potential application of hydraulic thresholds to process-based models that predict mortality.

TL;DR: Leaf- and stand-level observations provide mechanistic evidence that declining N availability constrained the tree response to elevated CO2; these observations are consistent with stand- level model projections.
