Our lab works at the interface between plant ecology and global change research. Much of our research focuses on understanding the biological and climatic drivers that promote shrub expansion into alpine tundra and the ecosystem consequences of the invasion of shrub populations upslope or northward beyond their current range limit.
|One of our primary research areas explores how shrubs are changing in tundra ecosystems.|
1. Are shrubs increasing in tundra ecosystems?
|There is growing evidence for increasing shrubs in many tundra ecosystems.||Increased shrubs could be due to a warming climate and improved growing conditions or a variety of other factors.|
2. Are shrubs advancing up slopes in alpine areas and moving northward into the Arctic?
3. Is increased shrub growth related to climate warming in tundra ecosystems?
|We work with collaborators working at sites around the Arctic. This is a map of some of the field sites from members of the Shrub Hub.||Patterns of shrub increase could vary across gradients in tundra ecosystems.|
