A new study by Tara Zamin and Paul Grogan reveals how global warming may increase vegetation growth and how nutrients can modulate this response.

A recent article in Environmental Research Letters by PhD student Tara Zamin and Professor Paul Grogan (Biology) shows that growth of tundra deciduous shrubs will increase as temperatures rise. Using a combination of satellite imagery and field and green house experiments, this study shows not only that warming will enhance growth but also that nitrogen and phosphorus limitation may constrain it. Tara's research is an important contribution to understanding  the biogeochemical functioning of tundra ecosystems and advances our ability to predict vegetation responses to climate change.
