Technical Abstract: Desert regions in the southwestern United States and northern Mexico exhibit a high degree of temporal variability in water availability with important consequences for transitions between grasslands and shrublands. This temporal variability is a result of: shifting climate regimes over centuries and decades, interannual variation in weather patterns, seasonal differences in the nature of winter and summer precipitation, within-season variability in precipitation frequency and magnitude, and feedbacks between vegetation and soil water.
