Table 2.

Days with leaf temperature maxima >35 °C in three alpine plant species recorded in summer 2012 or 2013

Rhododendron ferrugineum Tmax [°C] 35 36 37 38 39 40 41 42 43 45 46
1960 m a.s.l; 2012; jd 153–243 f [%] 38 32 26 20 16 13 9 6 5 2 1
Senecio incanus Tmax [°C] 35 36 37 38 39 40
2165 m.a.s.l.; 2013; jd 152–243 f [%] 39 28 17 13 5 1
Ranunculus glacialis Tmax [°C] 35 36 37

Altitude at the study site and the investigation period (year; julian days) are given for each studied species. Tmax are maximum half-hourly taken mean values (HHM) of temperatures in 1 °C classes. The frequency (f) describes the frequency of days at which a HHM was at least once higher than the corresponding temperature class.
