From: Phylogenomics of the Hyalella amphipod species-flock of the Andean Altiplano
Simplified dated phylogeny (chronogram) of Hyalella based on the 13 mitochondrial protein-coding genes. The ages of two nodes were implemented separately as constraints to calibrate the relaxed molecular clock (MRCA of node A and tree root after Adamowicz et al.14). Blue and red bars above nodes indicate 95% higher posterior densities for node ages when using 2.8 ± 0.4 Ma as age constrain for clade A and 20.63 Ma for the tree root, respectively. Nodes are numbered for discussion in the main text (nodes 1–12). Trees are available in nexus format in the GitHub repository (https://github.com/Frazapel/Hyalella-amphipod-Phylogenomics).
