Senescence Example

In Example 1, the TSS converges almost surely to an ESS near 2.88. Removing senescence raises the ESS from about 2.88 to 3.5. The net reproduction condition in Example 1 is satisfied for body sizes approximately between 0.35 and 3.65. Near the ESS in Example 1, successful mutant traits become rarer as their allowable range shrinks and extinction probabilities rise. Senescence favors faster reproduction over larger body size by restricting effective reproduction to early life. Example 1 models body size as the trait and uses a senescent birth function.
