Investigating drivers and consequences of changes in biodiversity
Our group investigates how changes in biodiversity alter ecosystem functioning, stability, and services. We also study how global environmental changes (e.g., habitat loss and fragmentation, nutrient enrichment, climate change, exotic species invasions) are driving changes in biodiversity and ecosystems. Most of our studies consider plant diversity in grasslands and forests. We have also reintroduced bison to an oak savanna.
research questions
- How do changes in biodiversity influence ecosystem functioning, stability, and services?
- How do global environmental changes impact biodiversity and ecosystems?
