Extended Data Fig. 7: Relationship of spring and autumn phenological dates from ground observations.

(A, B) Partial relationships of a multiple LMM, where EOS is the response variable and (A) the long-term trend (year) and (B) SOS are treated as fixed effects. (C) EOS versus SOS based on an LMM with SOS as a single fixed effect. In both bivariate and univariate models, site and species are treated as grouping variables of random intercepts. Black lines represent the expected mean values from LMMs and grey ranges their 95% confidence intervals. Colour hexagonal heatmap represents the observed data adjusted for the effects of the covariates.
