Fig. 12.2
Population growth through generations for annual bisexual, randomly mating populations all initiated with 172 founders arranged in a
square in the center of a large preserve (no individuals are dispersed out of the preserve). Conditions for all trials are identical except the following:
(1) Founders are placed with no spaces (graph A), 4 spaces (graph B), or 10 spaces between founders (graph C). (2) Maximum offspring and
microgamete dispersal distances are always equal within a trial, being either 2 grid units (graph symbols for trials a, e, or i), 5 grid units (b, f, or j),
12 units (c, g, or k), or 30 units (d, h, or l).
