The Department of Ecology welcomes Dr. Danielle Ulrich, Candidate for Plant Physiological Ecology Faculty, to campus as she presents her research seminar, "Approaches for characterizing plant physiological responses to environmental stress." Dr. Ulrich is a Chick Keller Postdoctoral Fellow, Bioscience and Earth & Environmental Sciences, Los Alamos National Laboratory.
Abstract: It is uncertain how predicted changes in climate will impact vegetation responses and distributions because the physiological mechanisms are not well understood. I use interdisciplinary approaches to characterize plant physiological responses to environmental stress at a range of temporal and spatial scales in mountainous, forested, and grassland ecosystems of the western US. Here, I present my research that aims to understand, predict, and mitigate plant physiological responses to and interactions with their environments. I use tree-ring stable isotopes and process modeling to reconstruct past physiological responses to abiotic and biotic environmental stress. I use heat and drought manipulation experiments to examine in situ physiological mechanisms and thresholds underlying vegetation responses to climate change to inform ecosystem carbon and water fluxes and species’ geographic distributions. The third component of my research investigates an often ignored piece of the puzzle: plant interactions with soil microbes. This interdisciplinary work is crucial because beneficial plant-microbe interactions can mitigate plant physiological responses to climate change.
