Fig. 15.9
Mean population size (A) and levels of heterozygosity (B) across 68 generations for
trials modeling establishment of the dioecious shrub
Lindera benzoin
. In trial m, 172 founders
were placed in squares of 43 at each corner with no founder closer than 80 grid units from a
border, while in trial M the same number of founders was placed in a single central square in
the preserve. In two other trials, there was only one square group of 43 founders placed either
at a preserve corner with no founder closer than 80 grid units from a border (trial v), or in a
single central square in the preserve (trial W). In every trial, there were 4 grid points between
all adjacent founders. All conditions among trials are otherwise the same (see conditions for
trials m and M, given in the text). Mean values shown are calculated from 45 duplicate runs
per trial. In graph B, both expected (e) and observed (o) heterozygosity values are given for
each trial.
