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.
Journal ArticleDOI
Thermal limits of leaf metabolism across biomes.

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.
Journal ArticleDOI
Convergence in the temperature response of leaf respiration across biomes and plant functional types
Mary A. Heskel,Mary A. Heskel,Odhran S. O'Sullivan,Odhran S. O'Sullivan,Peter B. Reich,Peter B. Reich,Mark G. Tjoelker,Lasantha K. Weerasinghe,Lasantha K. Weerasinghe,Aurore Penillard,John J. G.

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.
Journal ArticleDOI
Photosynthetically relevant foliar traits correlating better on a mass vs an area basis: of ecophysiological relevance or just a case of mathematical imperatives and statistical quicksand?
Jon Lloyd,Jon Lloyd,Keith J. Bloomfield,Keith J. Bloomfield,Tomas F. Domingues,Graham D. Farquhar +5 more
TL;DR: There has been an increasing tendency to express the photosynthetic characteristics of leaves on a dry-weight basis and this trend has been due, at least in part, to stronger correlations for mass-based photosynthesis rates with foliar properties thought to be important in their modulation.
Journal ArticleDOI
Implications of improved representations of plant respiration in a changing climate
Chris Huntingford,Owen K. Atkin,Alberto Martínez-de la Torre,Lina M. Mercado,Mary A. Heskel,Anna B. Harper,Keith J. Bloomfield,Odhran S. O'Sullivan,Peter B. Reich,Kirk R. Wythers,Ethan E. Butler,Ming Chen,Kevin L. Griffin,Patrick Meir,Patrick Meir,Mark G. Tjoelker,Matthew H. Turnbull,Stephen Sitch,Andy Wiltshire,Yadvinder Malhi +19 more
TL;DR: The authors show the implications of parameterisations with a global gridded land model and report significantly higher global plant respiration estimates, suggesting Rp could be around 30% higher than existing estimates.
