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 (Ic) were estimated by fitting a simple mechanistic model and the competition index (C) calculated as their quotient (See materials and methods). |
