Figure 2. Bayesian-inferred phylogenetic time tree of Gammarus alpinus sp. nov. and Gammarus lacustris. Values above branches (two decimal places) indicate likelihood based on 5406 combined trees. For better readability, individuals from Switzerland and Fennoscandia were also collapsed. Values at nodes (one decimal place) indicate the age of the branch in Myr. Branch lengths indicating divergence time (with a relaxed clock model).
