Table 2 The ability of males to inseminate females as a function of competition and female density. Estimates for the proportion of females inseminated by the addition of one male only (I₁) and the rate at which they are inseminated by additional competing males (I_c) were estimated by fitting a simple mechanistic model and the competition index (C) calculated as their quotient (See materials and methods).
