Conifers are a major source of sedimentary leaf wax n-alkanes when dominant in the landscape: case studies from the Paleogene
Plant wax n-alkanes are valuable paleoclimate proxies because their carbon (δ 13 C) and
hydrogen (δ 2 H) isotopes track biological and environmental processes. Angiosperms …

On geologic timescales, plant carbon isotope fractionation responds to precipitation similarly to modern plants and has a small negative correlation with pCO2
Leaf carbon isotope fractionation (Δ leaf) is sensitive to environmental conditions and can
provide insights into the state and evolution of leaf gas-exchange in response to climate and …
