Bottom-up effects of plant genotype on aphids, ants, and predators.

Ecology - 1 Jan 2008

Johnson Marc T J

Abstract excerpt

Theory predicts that bottom-up ecological forces can affect community dynamics, but whether this extends to the effects of heritable plant variation on tritrophic communities is poorly understood. In a field experiment, I contrasted the effects of plant genotype (28 genotypes; 1064 plants), aphid density, and the presence/absence of mutualistic ants in affecting the per capita population growth of a specialist...
