By grouping nonbreeding individuals into conservation regions, we developed migratory network models of American Redstart connectivity between breeding and nonbreeding populations. These are useful for highlighting different strategies for conservation.

We identified 5 genetically distinct breeding populations (colored polygons) to which we assigned individuals from nonbreeding range (points colored by assigned breeding pop), revealing high migratory connectivity.

We tested out WGSassign with the American Redstart! We amassed a large collection of samples…thanks to Darshan Narang for facilitating sample collection in Trinidad, @PeterPMarra for funding and Caribbean samples, @selvaorgco for Colombia samples, and many others

“Population assignment” methods use genetic signatures that differentiate breeding populations and assign individuals to them. We coded up our statistical developments in a python software package, WGSassign (https://t.co/pfVWBIrc1W)

How can we map animal migration with genomics? Here, I’ll present on our new software WGSassign to do just that and provide an example with the American Redstart
