Coevolution without Geographic Isolation

A new study was published a couple of days ago about the species I studied for my Master’s research. It shows that this population of crossbills (Loxia curvirostra) has coevolved with the local population of lodgepole pine despite other call types of the same species passing through their geographic range. These findings fly in the face of traditional examples of coevolution where only species that experience reproductive isolation coevolve with another species. For more information, you can read the article abstract and a short piece in Wired magazine.
