TL;DR: It is advocated for the view that relaxed selection and variable selection intensities are likely more important constraints to the evolution of plasticity than the costs of Plasticity, and opportunities to offset costs of phenotypes through ontogeny, amelioration of phenotypic costs across environments, and the condition-dependent hypothesis are examined.

TL;DR: A new global database of Rdark and associated leaf traits is analyzed and values at any given Vcmax or leaf nitrogen concentration were higher in herbs than in woody plants, and variation in Rdark among species and across global gradients in T and aridity is highlighted.

TL;DR: The largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3,800 observations representing 27 temperature manipulation studies, spanning nine biomes and over 2 decades of warming, finds that although warming increases soilrespiration rates, there is limited evidence for a shifting respiration response with experimental warming.

TL;DR: It is found that species in mid-latitude regions have the narrowest thermal safety margins in upper canopy leaves; these regions are at the greatest risk of damage due to extreme heat-wave events, especially under conditions when leaf temperatures are further elevated by a lack of transpirational cooling.

TL;DR: It is demonstrated that temperature-dependent increases in leaf respiration do not follow a commonly used exponential function, and are found to find a decelerating function as leaves warm, reflecting a declining sensitivity to higher temperatures that is remarkably uniform across all biomes and plant functional types.
