Tree-ring δ 13C tracks flux tower ecosystem productivity estimates in a NE temperate forest

Tree-ring δ 13C tracks flux tower ecosystem productivity estimates in a NE temperate forest

We investigated relationships between tree-ring δ ^13 C and growth, and flux tower estimates of gross primary productivity (GPP) at Harvard Forest from 1992 to 2010. Seasonal variations of derived photosynthetic isotope discrimination ( Δ ^13 C) and leaf intercellular CO _2 concentration ( c _i ) sh...
