Web17 May 2016 · The GMYC approach is based on branching rates along an ultrametric tree (here from BEAST) to distinguish between species-level (Yule, slower) and population-level (coalescent, faster) branching rates. This model identifies GMYC ESUs. For the GMYC approach, we used R 3.0.2 (R Core Team, 2012), library splits (Ezard et al., 2009). WebIt may be possible to use resampling of loci to check how the pattern of splits develops, and combine it with locus informativeness to find the best threshold for true species entities.
