Estimation of divergence time for cytb gene.
Divergence times between Aporodon clades were inferred in BEAST2
(Bouckaert et al. 2014). We
obtained a time-calibrated phylogeny using a Birth-Death model tree
prior and an uncorrelated relaxed lognormal clock. Substitution rate and
calibration nodes were established in the same way as in
Martínez-Borrego et al. (2022a). MCMC analyses were executed with two
runs of 10 million generations each, sampling once every 1000
generations. The BEAST log file was examined in Tracer
(Rambaut et al. 2018) to assess
the convergence of the independent runs, as well as the effective sample
size (ESS≥200). A Maxime clade credibility tree was obtained in
TreeAnotator after discarding the trees prior to the stationary phase as
burn-in.
