How Genotype-by-Environment Interactions Can Maintain Variation in Mutualisms.

Abstract excerpt

AbstractCoevolution requires reciprocal genotype-by-genotype (G × G) interactions for fitness, which occur when the fitness of a genotype in one species depends on the genotype it interacts with in another species and vice versa. However, in mutualisms, when G × G interactions are mutually beneficial, simple models predict that the resulting positive feedbacks will erode genetic variation. Here, we explore how...
