Dear Ecologgers, Please help me figure out some ecological genetics problem.
Does anybody have an idea of how to combine isolation by distance with time? I am running some analysis on genetic differentiation using molecular markers on an insect species. Isolation by distance is fine, but my sampling plan also involved subgroups originally from the same location but isolated for a long time. As some of the populations ended up in different continents. It would be incorrect to use the new home locations (after introduction) since we know fairly well the original field sources of almost all samples and an approximate date of recovery. I believe some method of combining the time since separation and geographical distance would capture this scenario better. Kindly let us know any ideas or experience with such an analysis. Kind regards, Aman
