Elizabeth Stacy (Life Sciences) and colleagues, including Donald Price (Life Sciences), published "Incipient Ecological Speciation between Successional Varieties of a Dominant Tree Involves Intrinsic Postzygotic Isolating Barriers" in the journal Ecology and Evolution. This study demonstrates that partial intrinsic postzygotic barriers may be among the first isolating barriers to arise during speciation between large, hybridizing populations of a long-lived species.
