Understanding carbon in ecosystems: biology, ecology, management, and environmental change
Why focus on carbon and ecosystems? Soils and plants store huge quantities of carbon. Disturbances that degrade ecosystems release this into the atmosphere – in forms such as carbon dioxide and methane – contributing to our changing climate. But soils and ecosystems are much more than reservoirs for carbon – their health is directly tied to water purification, flood prevention, maintenance of biodiversity, and agricultural production. Understanding how and why plants, animals, microbes and soils respond to environmental change will therefore help us understand the consequences for human and envrionmental well-being, and how we might manage them.
We use experimental and observational approaches to investigate these effects of global change, both in the field and laboratory. We primarily work across forests, agricultural lands, and grasslands in the United States.
The overall goal of our research is to provide the necessary mechanistic understanding required for reliable prediction of global change impacts on ecosystems, their likely feedbacks to the climate system, and to develop understanding that informs [more] sustainable management of agronomic and environmental services.
As our research goals reveal, we are increasingly combining basic and applied science, and our work is most advanced for the management of urban forests and for translating soil health goals to agronomic outcomes. To reach stakeholders, we’re working to produce both papers and concise summaries of the research reported within them. See for example a recent invited piece we produced about soil health initiatives for the Aspen Global Change Insitute by clicking here, and one of our recent one-page Publication Briefs by clicking here which shows how higher soil carbon helps to ‘drought proof’ corn yields. For urban forests, we’re collaborating with policy and practice organizations such as the Natural Areas Conservancy to help produce reports such the one available by clicking here that highlights the importance, threats and opportunities for protecting forests in cities.
