GENERATION
Fig. 9.6
F values (graph A) and the number of unique alleles retained (graph 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.
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.
