Fig. 1. Relationship between leaf-out day and first flowering
day for Lathyrus vernus individuals in the years 2013, 2014 and
2015 (n2013 = 198, n2014 = 207,
n2015 = 207).
Fig. 2. Relationships between fitness and (a) leaf-out day, (b)
first flowering day, and (c) the development time between leaf-out and
first flowering day in Lathyrus vernus in the years 2013 (left
panels), 2014 (mid-panels) and 2015 (right panels). Each point
represents the raw trait-fitness values for one individual. Dashed lines
represent total selection predicted from multiple regression models with
fitness (the number of intact seeds, relativized within years) as a
response variable, and (a) leaf-out day, (b) first flowering day, or (c)
the development time between leaf-out and first flowering day as the
predictor variable, and plant size (aboveground volume) included as a
covariate. Solid lines represent direct selection, predicted from
multiple linear regression models as above, but with both leaf-out day
and first flowering day included as predictors. All predictor variables
were standardized within years to 0 mean and unit variance before
analysis. Plant size was ln-transformed before standardization.
