Scatter plot from discriminant analysis of principal components. 80 principal components (PC) were selected after α-score estimations to avoid overfitting. Chosen discriminant analysis eigenvalues are depicted in the top right of the plot. Ellipses indicate the 95% confidence interval of assignment, yellow squares identify bumblebee individuals collected before the 1990s, orange rhombuses represent Portuguese samples, green represents individuals from Sierra de Guadarrama, pink represents individuals from the Sierra Nevada and blue represents samples from outside the Iberian Peninsula, as detailed in the figure legend at the bottom right.
