• Does the dispersal capacity of the organism determine whether environmental variation is course or fine grained?

Or, is grain solely a function of the environment?

Solution

Yes, the dispersal capacity of the organism determine whether environmental variation is course or fine grained because environmental heterogeneity is going to generate differential selection in the population in space or time. The environmental constrains are going to determine evolution of either plasticity as per dispersal capacity of organism in either heterogeneous dimension. The evolution of phenotypic plasticity varies with dispersal capacity of organism & it is either coarse-grained variation or fine-grained variation as per prevailing environmental conditions.
