In this paper, we develop an individual-based model of mating dynamics that accounts for spatial search of one sex for another, and quantify the rate at which females mate, depending on male and female densities and under a number of reasonable mating scenarios. This rate is found to increase with male and female densities (and we thus observe a mate-finding Allee effect), in a decelerating or sigmoid way. We also show that mating can be most efficient at either low or high female densities, and that the mate search rate may undergo density-dependent selection. Finally, mate search trajectories evolve to be as straight as possible when targets are sedentary.
