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.
