AimTamarack (Larix laricina) is an early‐successional transcontinental boreal conifer occurring within the spruce‐fir dominated forest. The aim was to infer the species biogeographical history and to assess the putative genetic imprint left by interspecific competition during post‐glacial migration, using cytoplasmic DNA and fossil data.
LocationForty‐five locations were sampled across the transcontinental...
Secondary contact between closely related taxa routinely occurs during postglacial migrations. After initial contact, the location of hybrid zones may shift geographically or remain spatially stable over time in response to various selective pressures or neutral processes. Studying the extent and direction of introgression using markers having contrasted levels of gene flow can help unravel the historical...
