Table 5 Linear selection gradients (β) for recruitment and flowering time for six A. thaliana populations, three with low (AGU, BON, and CAI) and three with high (MAR, MDC, and POB) genotypic and ecological diversity in edge and core environments, respectively, estimated from the first (2018–2019) and second (2019–2020) experiments conducted in the same common garden facility. Sample size (N) for each population and experiment used in the analysis is indicated. β-values for BON in the first experiment could not be estimated due to low sample size (see text for details). See Table S5 for results of the complete analysis. Significance: ***, P < 0.0001; **, P < 0.01; *, P < 0.05; ns, non-significant
