Tree construction and calibration workflow. a base topologies are manually constructed in Mesquite, b base topologies are exported to RStudio and their polytomies stochastically resolved, c Branch lengths are calibrated using species age, 1000 time calibrated trees are generated for each topology in steps (b) and (c, d) branch tips of species represented by multiple specimens are replaced with a branch length 0 polytomy in order to account for intraspecific variation
