Peri’s second paper was published today in Molecular Ecology. It was a follow up to her first paper which attracted useful discussion by Anders Forsman (Lund, Sweden). The new paper clarifies our thoughts on why polymorphic species might be vulnerable because of the negative interactions between different morphs. Conceptually it builds from our work on the Gouldian finch and long-tailed finch.
