Agriculture creates subtle genetic structure among migratory and non-migratory populations of burrowing owls throughout North America

Alberto Macías-Duarte, Courtney Conway & Melanie Culver
Population structure across a species distribution primarily reflects historical, ecological and evolutionary processes. However, large-scale contemporaneous changes in land use have the potential to create changes in habitat quality and thereby cause changes in gene flow, population structure, and distributions. As such, land-use changes in one portion of a species range may explain declines in other portions of their range. For example, many burrowing owl populations have declined or become extirpated near the northern edge...
