Introduction Altered precipitation regimes will occur in mid-latitude regions with increasing precipitation amount and frequency of extreme rainfall events (IPCC 2007).This could alter the dynamics of soil water availability, which has important ecological consequences, particularly in water-limited ecosystems (Knapp et al 2008).
