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?

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?
