The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a...
The potential impact of projected climate warming on the terrestrial hydrologic cycle is
uncertain. This problem has evaded experimentalists due to the overwhelming challenge of measuring the
entire water budget and introducing experimental warming treatments in open environmental systems. We
present new data from a mesocosm experiment that examined the...

Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...
