Extended Data Fig. 3: The potential relationships behind the scale dependency of the stabilizing effect of crop diversity.
From: Larger nations benefit more than smaller nations from the stabilizing effects of crop diversity
Shown are the relationships between (a) the number of farms and effective crop diversity, (b) crop diversity and the average area of crops, as well as (c) the number of farms and the average stability of individual crops, (d) the average area of crops and the average stability of individual crops. Coloured lines with shades represent fits from linear regressions and 95% confidence intervals. Solid lines show significant relationships (P < 0.05); dashed lines show nonsignificant relationships. Linear model results are shown in each panel. Sample size (n) is 673. Two-sided t-test was used for statistical testing. ***P < 0.001; **P < 0.01; *P < 0.05. The marginal histograms show the frequency distribution of respective variables within each country group.
