Macroecology belowground

Much of our knowledge of global biodiversity patterns and the underlying processes that drive them is based on aboveground organisms in terrestrial ecosystems. We are examining global patterns of earthworm diversity, how aboveground and belowground diversity patterns vary at large scales, and how soil biodiversity changes over time.

Key questions we're working on include: 

• How do key drivers of diversity (e.g., climate and habitat) affect distributions of native versus non-native earthworms?

• How do soil ecological indicators change over time at the global scale?
