Parasite-Host-Vector Interactions

Population genomics of parasitic plants

  • How are parasite populations genetically structured within and across host individuals? space? host species?
  • How are parasite species structured across their geographic range? How do ecological interactions (host species, biotic dispersal), environmental characteristics, and geography interact to determine that structure?Characterizing the infection of a desert ironwood (Olneya tesota) by desert mistletoe (Phoradendron californicum)

Reproductive isolation of parasitic plant host races

  • Is there selection for increasing pre-zygotic barriers to reproduction between host races?

Host-parasite-vector interactions across scales

  • How do within-host processes translate into parasite fitness?
  • What are the ecological causes and consequences of host-associated genetic differentiation?
