The PSU Ecohydrology lab studies how water moves through ecosystems, both natural and urban. This process is strongly impacted by vegetation and its nonlinear responses to climate and soil moisture. We study some of the ways in which plants have evolved their hydraulic and photosynthetic strategies to adapt and thrive in water-limited ecosystems, and what this means for the future of natural ecosystems and agricultural lands impacted by climate change. To do so we use a combination of computational modeling, field and greenhouse experiments, probability theory and nonlinear dynamics.
