Figure 3From: The high Andes, gene flow and a stable hybrid zone shape the genetic structure of a wide-ranging South American parrotSpatial clustering of multilocus burrowing parrot ( Cyanoliseus patagonus ) genotypes in landscape space. The most likely hard clustering posterior was superimposed on to a map of the region to convey patterns of spatial clustering of four populations in Chile and Argentina. A model for the colonisation and diversification events that have shaped mitochondrial population structure is also depicted. Each dot represents a sampling location (see also Additional file 1 Table S1). The arrows indicate the migration model proposed for the species. A graphical representation of the high Andes in the region has been added (in light brown) together with the exact location of all known passes in the region.Back to article page
