Research

We investigate how ecosystem responses to global change drivers are mediated by biotic processes. Specifically, we study how ecosystem function is influenced by mutualisms, competition, consumers, and alterations in abiotic resource availability. Projects in our lab examine a diverse suite of global change drivers, such as nutrient deposition and runoff, consumer loss, altered climatic regimes, and species invasions, and span a broad range of ecosystems including grasslands, forests, and agroecosystems. We use tools such as observational data collection, long-term field experiments, and data synthesis to address critical questions related to global change in these natural and working landscapes.
