Sexual conflict is a critical component of sexual selection, but historically, research in male-competitive and coercive mating systems has focused on male mating strategies and overlooked long-term costs to females and female counterstrategies to male coercion. This dissertation examines female reproduction in the context of sexual coercion and conflict in Indo-Pacific bottlenose dolphins (Tursiops aduncus) in Shark Bay, Australia. Chapter 1 demonstrates that reported cases of infant killing in cetaceans are consistent with the hypothesis that adult males can increase their own reproductive success by killing an unrelated infant. We hypothesize that infanticide risk in whales is modulated by encounter rates with unfamiliar males. Chapter 2 shows that bottlenose dolphin males have higher mortality risk than females in the juvenile period, but not during adulthood. This result challenges the idea that male-male competition results in consistent female-biased survival in mammals and suggests that substantial female investment in reproduction can elevate female mortality risk. Chapter 3 investigate costs of male-coercion to female reproduction and survival in bottlenose dolphins. Females who fail to successfully raise calves spend more time in consortship in early adulthood and are at higher risk of mortality throughout the adult period than reproductively successful females. These findings suggest that reproductive failure in early adulthood may result in compounding costs of reproduction that reduce female fitness. Finally, Chapter 4 explores female mate choice in the context of sexual coercion in bottlenose dolphins. We show that middle-aged (age 25 - 35) males who are local to and socially associated with a female are more likely to sire her offspring. Within alliances, paternity is biased towards males who share less home range overlap with the mother. Within the constraints of male coercion, females may be able to bias paternity towards males with less home range overlap, potentially minimizing the risk of inbreeding. This dissertation provides evidence of the extreme costs of coercion and sexual conflict to females in this species, and of potential female counterstrategies to coercion.
