Figure 8.

Amount of immigrant alleles received by a northern population. Absolute number of immigrant alleles into a population located at the extreme northern latitude (+0.5 dotted circle in Figure 1). Numbers on the y-axis are cumulative counts of alleles from generation 16 to 20. Counts of alleles were monitored at three strengths of assortative mating and three levels of the environmental cline. The red line indicates strong assortative mating (ρ = 0.8), the blue line moderate assortative mating (ρ = 0.3), the black line random mating (ρ = 0), and the purple line strong assortative mating under an extreme environmental cline (ρ = 0.8, kE = 3). Lines are mean values of 50 replicates for each evolutionary scenario.
