Global flyway evolution in red knots Calidris canutus and genetic evidence for a Nearctic refugium
Abstract Present‐day ecology and population structure are the legacies of past climate and habitat perturbations, and this is particularly true for species that are widely distributed at high latitudes. The red knot, Calidris canutus , is an arctic‐breeding, long‐distance migratory shorebird with si...

Together, these results suggest that relative gene flow among migratory populations reflects a complex interplay of historical, geographical, and ecological factors.

Abstract Present‐day ecology and population structure are the legacies of past climate and habitat perturbations, and this is particularly true for species that are widely distributed at high latitudes.
