Leaf wax D/H ratios are widely used to reconstruct environmental water D/H ratios in paleoclimatology. However, accurate quantitative assessment of precipitation D/H ratios from sedimentary …
This thesis explores the evolution of heterospory (the production of different sized spores in land plants). Heterospory is one of the fundamental innovations in land …
Global forests are a large and dynamic carbon stock. Biological processes such as photosynthesis, respiration, and mortality control fluxes of carbon into and out of …
