Density-dependent selection on mate search and evolution of Allee effects

Popis výsledku v původním jazyce

We develop an individual-based, eco-genetic model to study how mating systems and fitness trade-offs interact with changes in population density to drive evolution of the rate at which males or females search for mates. We find density-dependent selection when fecundity costs are imposed on mate search, leading to search rates that result in lower Allee thresholds in populations kept at lower densities. This provides an explanation for why Allee effects are often observed in anthropogenically rare species. Optimizing selection, runaway selection and evolutionary suicide may also occur. We emphasize the crucial role that mating systems, fitness trade-offs and the evolving sex have in determining the density threshold for population persistence, in particular since evolution need not always take the Allee threshold to its minimum value.
