Stressful environments are often said to increase the expression of inbreeding depression. Alternatively, Crow's "opportunity for selection" (the squared phenotypic coefficient of variation) sets a limit to how much selection can occur, constraining the magnitude of inbreeding depression. To test these hypotheses, we planted self- and cross-fertilized seeds(More)
Plants can achieve an appropriate phenotype in particular conditions either constitutively or plastically, depending in part on the grain size of the environmental conditions being considered. Coarse-grained environmental variation should result in selection for local adaptation and no selection on plasticity to novel levels of the coarse-grained(More)
