Fig. 2From: Fine-scale habitat heterogeneity favours the coexistence of supergene-controlled social forms in Formica selysiThe frequency of social forms varies with colony density. Each point corresponds to a plot, with the symbol indicating its habitat category. The points have been jittered for better visualization. Regression curve represents a simplified GAM model, with the number of monogyne and polygyne colonies as response variable and colony density as fixed factorBack to article page
