Parameter values used to run the weather generator under different climatic scenarios.

Current climate indicate parameters used to run the model under current climate based on instrumental records (weather station at Senda Darwin Biological Station, period 1998–2009). Radiation describes parameters daily global radiation Rgµ and Rgσ (the latter in brackets, µmol(photons) m−2 s−1). Temperature is mean daily air temperature. Future scenarios are the range of climatic parameters that were varied to run the model under increased drought (36 scenarios in total, see Methods for details). DJF: December to February (austral summer, growing season); MAM: March to May (austral autumn); JJA: June to August (austral winter), SON: September to November (spring, growing season). sd: standard deviation.
