Figures & data
FIGURE 1. Duration in days to reach the phenological phases first bud, main bud, first blossom, and main blossom from their preceding stage are illustrated as mean, 1st/3rd quartile (boxes), and 10th/90th quantile (whiskers) with all outliers. Data pooled for all species
FIGURE 2. Percentage and number of individuals with mature seeds and species with at least one plant that has completed its reproductive cycle in 2001
TABLE 1 Basic climatic description of study sites for phenological observations. Data derived from StowAway Tidbit dataloggers. Snowfree period was calculated by interpreting the daily soil temperature amplitudes. Growing period was defined as all times with measurements above 5°C. Temperature sums were calculated by summarizing all temperature values exceeding 5°C
TABLE 2 Temperature sum in cumulative °C and time span from snowmelt to main blossom and fruit in number of days (mean ± SD). Early flowering: Oxyria digyna (OD), Veronica alpina (VA); intermediate flowering: Sedum alpestre (SA), Leucanthemopsis alpina (LA), Gnaphalium supinum (GS); late flowering: Agrostis rupestris (AR), Poa laxa (PL).
