e0“Both ecological niche modelling and the very low genetic subdifferentiation are congruent with a tabula rasa scenario for the Patagonian Channels.”

Other claims from this paper (7)
- Observation A. pumila populations formed one genetic cluster.
- Observation The Nahuelbuta D. fascicularis population was genetically distinct.
- Observation Other D. fascicularis populations formed a cluster with little substructure.
- Observation Models indicated suitable glacial habitat in south-central Chile.
- Observation The populations survived the last glacial northwest of the ice sheet in south-central Chile.
- Observation Southern regions were recolonized from highly bottlenecked source populations.
- Mechanism Wind-mediated gene flow may also have shaped population genetic patterns.
