Modelling Eastern Spread Risk of Mountain Pine Beetle Using Host Genetic Ancestry

The research will consider the host genetic ancestry of jack pine and the probability of eastern spread of the MPB. Mounting evidence indicates that that jack pine is an equivalent host for MPB in comparison to lodgepole pine.


  1. Use all existing genotype data to develop an updated predictive surface of pine ancestry for Alberta
  2. Ground-truth the predicted pine ancestry by sampling and genotyping pine samples in locations (~10 locations, 20 individuals in each location) where there are strong transitions in ancestry
  3. Develop a spatial model that examines the relationship between MPB incidence data and pine-host genetic ancestry addressing the complementary hypotheses:
    Hypothesis 1: Jack pine represents a sink population for MPB
    Hypothesis 2: Pine genetic ancestry does not influence eastern MPB range expansion
