Figure 3

Circular migration plot (chord diagram). Migration rates (m) are plotted between the Isle of Man (IoM), Ireland (IRE), Scotland (SCO) and the temporal samples from Ireland 2012 (IRE_12), based on the output matrix from BayesAss. Sampling locations are given on the outside of the circle, where “S” preceding the location denotes the source population from which individuals migrated. The thickness of the arcs represents the rate of migration; only migration rates values > 0.10 are listed and indicated with an arrow. Values in bold and italic are the proportions of individuals derived from the source populations.
