The ecological costs to females in a system with allied sexual coercion

摘要: Sexual coercion results from extreme conflict over mating. As a male strategy to overcome female resistance, can impose fitness costs on females. Among mammals, most cases involve single males or temporary coalitions, with allied aggression towards females being rare. Shark Bay bottlenose dolphins, Tursiops cf. aduncus, alliances harass, guard and consort obtain mating access, which has known physical However, the behavioural ecological of sexual remain largely unexplored. Given importance individual differences in ranging habitat use for dolphin foraging ecology, social networks fitness, we hypothesized that also imposes Using 25 years longitudinal data, examined how adult presence relates space use, found (N = 32) altered their when associating but they were cycling. Additionally, reduced primary (preferred) males, cycling had no effect. Ranging shifts slightly greater than together, only did this alter spatial ecology. While it is possible follow fertile and/or move avoid well-documented coercive system suggests as part tactics, sequester areas would not otherwise occupy. Our show system, females' basic suggest spatially via consortships.
