Multiple lines of evidence suggest that plant water-use efficiency (WUE) -the ratio of carbon assimilation to water loss- has increased in recent decades. Although rising atmospheric CO2 has been proposed as the principal cause, the underlying physiological mechanisms are still being debated, and implications for the global water cycle remain uncertain.

38 p, 992.1 KB Evaluating climate signal recorded in tree-ring δ¹³C and δ¹⁸O values from bulk wood and α-cellulose for six species across four sites in the northeastern US / Guerrieri, Rossella (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Jennings, Katie (University of New Hampshire. Earth Systems Research Center) ; Belmecheri, Soumaya (University of Arizona. Laboratory of Tree Ring Research) ; Asbjornsen, Heidi (University of New Hampshire. Earth Systems Research Center) ; Ollinger, Scott (University of New Hampshire. Earth Systems Research Center)
Rationale : we evaluated the applicability of tree-ring δ¹³C and δ¹⁸O values in bulk wood - instead of the more time and lab-consuming α-cellulose δ¹³C and δ¹⁸O values, to assess climate and physiological signals across multiple sites and for six tree species along a latitudinal gradient (35°97'N to 45°20'N) of the northeastern United States.
