GENERATION
Fig. 10.4
Mean observed heterozygosity (A) and F values (B) across generations for four
populations with mostly identical initial input conditions (including 20 founders with adjacent
individuals in closest spacing) except that: w = founders placed in two, centrally placed lines
of 10 each; populations c, y, and e = founders broken into four groups of fi ve founders each,
each group removed from the preserve center towards one of the four corners, with the
founder nearest the center being displaced by 15 units in the x and y directions. Populations
have the reproduction rate values (r) indicated above. Different numbers of generations were
examined for different populations. Means are based on 30 replicate runs per trial. Preserves
and placement of founders not drawn to scale (preserve includes 26,214,400 grid units).
