The Extreme Drought in Grassland Ecosystems (EDGE) experiment is replicated at 6 sites in NM, CO, WY, and KS. It is one among many ecosystem manipulations that will be incorporated into the synthesis study.
We characterized the sensitivity of biological soil crusts to drought (drought plot in photo) in dry grassland ecosystems (Fernandes et al. 2018). We also documented plant evolutionary responses to drought (Whitney et al. 2019)
We are directly testing how climate mean and variance interacts by building the first field experiments that cross long-term drought with increased rainfall variability.
