Abstract: Understanding how terrestrial ecosystems will respond to global changes -such as climate change and increased nitrogen deposition -has many implications for picturing our future world. This talk will focus on considering how such changes could concurrently and interactively affect different aspects of ecosystems, in particular, plant growth, belowground microbial carbon cycling, and plant and soil community composition. I will use datasets from tropical forests in Hawai’i, drylands of the Colorado Plateau, and global synthesis activities to link nutrient limitation above-and belowground, investigate climate change effects on plant and soil community function and structure, and to explore how comparing responses from very different ecosystems can inform our understanding of larger controls. We will also consider how these ecosystem responses to environmental perturbation may feedback to affect the pace and direction of future global change.
