GENERATION
Fig. 9.5
Mean values for population size (A) and observed heterozygosity (B) across generations
for populations initiated with identical conditions except for the placement of the central 20
founders: v = two central horizontal lines; e = one line of 20 horizontal founders; f = a cross
of 10 by 10 founders; and g = 20 founders forming perimeter of a hollow square (six founders
on an edge). Adjacent founders were always placed on adjacent average density grid points.
Symbols at the top are not to scale: the preserve was 5,120 average density grid points on a
side, creating a preserve with 26,214,400 establishment points. At 16 generations, the mean
values for trial e in both graphs A and B signifi cantly differ (p < 0.05) from the means of all
of the other trials, but none of the latter differ among themselves.
