Biology Seminar: Martin Venturas, "The importance of plant hydraulics for predicting the vulnerability of forests to climate change"

Dr. Martin Venturas, University of Utah, researches plant hydraulics and forest ecophysiology. Currently, he is working on modeling how different plant hydraulic functional traits affect forest responses to drought.

Seminar, 4:10pm, B19
"The importance of plant hydraulics for predicting the vulnerability of forests to climate change"

Abstract: Modeling forest responses to environmental conditions is critical for predicting the impacts of climate change on forest ecosystems as well as forest feedbacks to global warming. However, modeling forest responses is challenging due to limitations in our ability to model stomatal behavior and to predict tree mortality. Stomata are small pores in the surface of leaves that plants open to uptake CO2 for photosynthesis, but by doing so plants also lose water to the atmosphere. Thus, plants regulate stomatal aperture to enable carbon gain and avoid excessive dehydration that can lead to mortality. We recently developed a model that uses optimization theory to predict stomatal behavior. I will talk about research we have performed for developing and testing this plant hydraulic traits based model. I will also highlight the importance of understanding how hydraulic traits acclimate to environmental conditions for predicting forest future responses with mechanistic models.

Student Lunch: Students are also invited to join Martin Venturas at noon on Friday before the afternoon seminar. Spots are limited, so early RSVPs are encouraged. RSVP here to join the student lunch.
