**2.1.8 Generations**

Beginning with the founders, 100 bouts of reproduction (101 generations or ages including the founding generation) were conducted for each set of trial conditions. Output results in Figures 1 to 3 are reported for the entire population at each age. For the pollen and offspring dispersal distance comparison trials (Figures 4 to 6) only the results at the terminal age 100 are given.

#### **2.1.9 Replicate runs**

The output values reported are mean values calculated from 40 replicate runs for each set of trial input conditions. When trials are said to differ, we mean that reported generation mean values differ significantly (p value < 0.05) unless otherwise stated. This convention is used rather than reporting each standard deviation and t-test results for all trial comparisons.
