Can the genetics of one organism in the ecosystem affect the genetics of another?

Goldenrod and Goldenrod Gall Fly

Host-associated differentiation (HAD)

Community Ecology Goldenrod and Goldenrod Gall Fly - Parasite Positive Negative - Plant tissue swells
-Galls can attract parasitoid -flies have warm, nutritious home
-flies are protected from most but not all predators
-Doesn't kill either species Ecosystem Ecology Type: Grassland How do nutrients cycle in the prairie?
-Controlled burns Human Impacts - Lawn Mowing Paths
- Prescribed Burns
- Removing Patches of the prairie
- Destruction of Habitat
- Treatments
