Immunoecology of Species with Alternative Reproductive Tactics and Strategies

Figure 1

Frequency and reproductive success of “normal” and “alternative” males during the evolution and establishment of ARTS in a population. “Size” is used in the x-axis, but it could also be any other aspect of behaviour or morphology that is important in mating. At the start, on the left, there is only one morph with a highly skewed distribution in reproductive success. At the end, on the right, there are two distinct groups. The final relative frequencies of the 2 morphs might vary depending on the equilibrium that is eventually reached.
