Genotype-by-environment interactions for fitness of Erigeron annuus show fine-scale selective heterogeneity

The results of natural selection depend critically on whether variation in fitness is fine-grained or coarse-grained with respect to dispersal, but little is known of the spatial scale of fitness variation in natural populations. For most evolutionary questions, environmental heterogeneity must be d...
