Ancestral range estimation with the R package BioGeoBEARS v.1.1.2. This script is based on the example script of BioGeoBEARS. The outgroup was excluded from this analysis
Please see the BioGeoBEARS website for documentation.
All three available range evolution models (DIVA, DIVALIKE, BAYAREALIKE) were applied, without the jump dispersal parameter (+J). For each range evolution model, three dispersal probability models were tested:
- M0: without any dispersal constraint. all dispersal probabilites are equal
- MF: dispersal probability matrices adapted from Federman et al. (2015)
- MB: dispersal probability matrices adapted from Baker and Couvreur (2013)
These nine models were compared with the AICc.
This script is the same as biogeobears_without_node_constr.R, except that the outgroup was included and the basal node was constraint to the area "SE" (i.e. Southeast Asia and Eurasia) based on Baker (2013).
