Bayesian factor (BF) test for significant non-zero dispersion routes in NoV GI (a) and GII (b). Only routes supported by a BF greater than 3 are plotted. The line color represent the relative strength by which the routes are supported: dark red lines and bright red lines suggest weak and strong support respectively. The maps are based on satellite pictures made available in Google Earth (http://earth.google.com)
