On the nonidentifiability of migration time estimates in isolation with migration models.
In recent years, many studies have found evidence of gene flow between diverging populations by analyzing genetic data under an Isolation with Migration (IM) model (Pinho and Hey 2010). Given evidence of gene exchange, investigators often then wish to inquire of the time when gene flow occurred (e.g. Won & Hey 2005; Becquet & Przeworski 2009). For example, a model of divergence with gene flow w...

Isolation with migration models for more than two populations.
A method for studying the divergence of multiple closely related populations is described and assessed. The approach of Hey and Nielsen (2007, Integration within the Felsenstein equation for improved Markov chain Monte Carlo methods in population genetics. Proc Natl Acad Sci USA. 104:2785-2790) for fitting an isolation-with-migration model was extended to the case of multiple populations with a...
