Understanding the physical and genetic structure of hybrid zones can illuminate factors
affecting their formation and stability. In north‐central A lberta, lodgepole pine (P inus
contorta D ougl. ex L oud. var. latifolia) and jack pine (P inus banksiana L amb) form a
complex and poorly defined hybrid zone. Better knowledge of this zone is relevant, given the
recent host expansion of mountain pine beetle into jack pine. We characterized the zone by
genotyping 1998 lodgepole, jack pine, and hybrids from B ritish C olumbia, A lberta, S …

Understanding the physical and genetic structure of hybrid zones can illuminate factors
affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta
Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and
poorly defined hybrid zone. Better knowledge of this zone is relevant, given the recent host
expansion of mountain pine beetle into jack pine. We characterized the zone by genotyping
