EEB Seminar Series: "Predicting forest responses to drought stress by linking stomata to whole-plant hydraulic strategies." Bill Anderegg, Ph.D. University of Utah

Forests absorb a quarter of human carbon dioxide emissions, greatly slowing down climate change, but the future of Earth's forests in a rapidly changing climate is highly uncertain. Plant stomata exert first order control on carbon, water, and energy cycling in ecosystems, yet most predictions of stomatal conductance arise from empirical regression models, which may not apply well in future climates and during strong droughts. I will highlight several challenges in the field of predictive understanding of plant responses to drought stress, including linking stomata to plant hydraulic transport and strategies. I will further show recent and ongoing research on a new evolutionary approach that links plant carbon uptake through stomata and plant hydraulics in a predictive framework that has strong potential for improving ecosystem and vegetation models, including the impact of trait diversity within a forest community, in a more extreme climate.
