Leaf design, its evolution, and importance for ecosystems past, present and future


Leaves are tremendously diverse in structure and physiology. Innovations in theory and measurement practices have shown that this diversity has major significance for whole plant function and evolution. My group combines mechanistic and phylogenetic approaches in studies at a wide range of scales, including determining the ecological consequences of the enormous diversity in structure and hydraulic physiology; clarifying the evolutionary diversification of leaf physiology across life forms and in adaptive radiations including mosses, ferns, grasses, and maples, and Hawaiian euphorbs, lobeliads, plantagos, and violets; providing new information toward preserving rare and endangered species; developing applications for estimating the ecology of ancient forests from fossil leaves; and applying physiology toward predicting the dynamics, productivity and ecohydrology of forests subject to global change.
