| resource stability and geographic isolation are associated with genome divergence in western palearctic crossbills. | while many conifers produce annually variable seed crops, serotinous species (which hold seeds in cones for multiple years) represent unusually stable food resources for seed predators. such stability is conducive to residency and potentially population divergence of consumers as exemplified by the cassia crossbill (loxia sinesciuris) in north america. we used genotyping by sequencing (gbs) to test whether three mediterranean subspecies of common crossbills (l. curvirostra) associated with the s ... | 2018 | 30125437 |
