The following files  are included in the package:

0) "readme.txt"
This file, including a description of the data included in the other files
and the codes and measurement units of variables (and their levels).
In all the following files "NA" indicates missing data.

1) "df1.txt"
Dataset including the developmental rates for the 5 phenophases of the 3 species investigated.
Used for Table 1a and Figure 2.
Codes:
	column 1: sp = Species (3 levels: ca = Cardamine alpina, la = Leucanthemopsis alpina, va = Veronica alpina)
	column 2: s.dr = Developmental rate [prior to scaling, in day^-1], scaled within each phenophase (for each species)
	column 3: t = Mean air (+5 cm) temperature [in °C] during the period
	column 4: pp = Phenophase (5 levels: pp1 = unopened buds, pp2 = flowering, pp3 = initiated fruits, pp4 = expanding fruits, pp5 = seed dispersal)
	column 5: yr = Year (5 growing seasons: 2010 to 2014)
	column 6: pl = Plot (20 levels)

2) "df2.txt"
Dataset including the developmental rates from the snowmelt time to seed dispersal of the 3 species investigated.
Used for Table 1b and Figure 3.
Codes:
	column 1: sp = Species (3 levels: ca = Cardamine alpina, la = Leucanthemopsis alpina, va = Veronica alpina)
	column 2: drt = Developmental rate [in day^-1]
	column 3: tt = Mean air (+5 cm) temperature [in °C] during the period
	column 4: yr = Year (5 growing seasons: 2010 to 2014)
	column 5: pl = Plot (20 levels)


3) "df3.txt"
Dataset including the developmental rates from the snowmelt time to flowering of the 3 species investigated in earlier and later snowmelt locations.
Used for Table 2.
Codes:
	column 1: dr.pre = Developmental rate [in day^-1]
	column 2: sm = Snowmelt location (2 levels: E = earlier, L = later)
	column 3: t.pre = Mean air (+5 cm) temperature [in °C] during the period
	column 4: sp = Species (3 levels: ca = Cardamine alpina, la = Leucanthemopsis alpina, va = Veronica alpina)
	column 5: yr = Year (5 growing seasons: 2010 to 2014)
	column 6: pl = Plot (20 levels)


4) "df4.txt"
Dataset including the developmental rates of the pre- and post-dispersal phenoperiods of the 3 species investigated in earlier and later snowmelt locations.
Used for Table 3a and Figure 4.
Codes:
	column 1: s.dr = Developmental rate [prior to scaling, in day^-1], scaled at the species level
	column 2: t = Mean air (+5 cm) temperature [in °C] during the period
	column 3: pha = Phenoperiod (2 levels: pre = Pre-dispersal, post = Post-dispersal)
	column 4: sm = Snowmelt location (2 levels: E = earlier, L = later)
	column 5: sp = Species (3 levels: ca = Cardamine alpina, la = Leucanthemopsis alpina, va = Veronica alpina)
	column 6: yr = Year (5 growing seasons: 2010 to 2014)
	column 7: pl = Plot (20 levels)

5) "df5.txt"
Dataset including the developmental rates from the snowmelt time to seed dispersal of the 3 species investigated in earlier and later snowmelt locations under control and warmer temperatures.
Used for Table 3b.
Codes:
	column 1: drt = Developmental rate [in day^-1]
	column 2: sp = Species (3 levels: ca = Cardamine alpina, la = Leucanthemopsis alpina, va = Veronica alpina)
	column 3: sm = Snowmelt location (2 levels: E = earlier, L = later)
	column 4: trt = Temperature treatment (2 levels: C = control, W = warmer)
	column 5: yr = Year (5 growing seasons: 2010 to 2014)
	column 6: pl = Plot (20 levels)
