Environmental changes, including elevated CO2, climate change, enhanced nutrient deposition, change in land use type and intensity, and species invasions, are contributing to worldwide loss of biodiversity. Ecosystem responses may either buffer or exacerbate these changes through various feedback loops, with important implications for the services ecosystems provide to humanity. Whole-ecosystem studies provide a complement to modeling approaches and smaller scale studies to test whether our understanding of the underlying mechanisms scale up, and if not, which other processes need more consideration. This chapter evaluates the use of serpentine grasslands as model systems for understanding whole-ecosystem responses to two different global changes: loss of biodiversity and elevated atmospheric CO2.

Keywords: ecosystem studies; serpentine ecosystem; serpentine grassland; model system biodiversity; atmospheric CO2
