Rapid response to anthropogenic climate change by Thuja occidentalis: implications for past climate reconstructions and future climate predictions.

ABSTRACT: Carbon isotope values of leaves (δ¹³C_leaf) from meta-analyses and growth chamber studies of C₃ plants have been used to propose generalized relationships between δ¹³C_leaf and climate variables such as mean annual precipitation (MAP), atmospheric concentration of carbon dioxide ([CO₂]), and other climate variables. These generalized relationships are frequently applied to the fossil record to create paleoclimate reconstructions. Although plant evolution influences biochemistry and response to environmental stress, few studies have assessed species-specific carbon assimilation as it relates to climate outside of a laboratory. We measured δ¹³C_leaf values and C:N ratios of a wide-ranging evergreen conifer w
