Aggression in bottlenose dolphins: Evidence for sexual coercion, male-male competition, and female tolerance through analysis of tooth-rake marks and behaviour

Aggressive behaviour is rarely observed, but may have a large impact on the social structure, relationships and interactions in animal societies. Long-term behavioural study of Indian Ocean bottlenose dolphins in Shark Bay, Australia, suggests that males are more aggressive than females, and use sexual coercion during the breeding season, but age and sex-specific patterns of aggression have not been well documented. We analyzed tooth rake marks, an indirect measure of received conspecific…

Mating in a bisexually philopatric society: bottlenose dolphin females associate with adult males but not adult sons during estrous
This study provides evidence for long-term kin recognition and detection of both estrous and early pregnancy among wild bottlenose dolphins and has implications for the evolution of bisexual philopatry, fission-fusion dynamics, and infanticide—or lack thereof—in mammals.
Patterns of intraspecific aggression inferred from injuries in an aquatic turtle with male-biased size dimorphism
It is found that both sex and body size were important predictors of risk of wounding, consistent with the hypothesis that male–male sexual competition is the primary driver of intraspecific aggression.
Social factors affecting female behavior, ecology, and fitness in wild bottlenose dolphins
This dissertation exploits the 30-year longitudinal dataset on Shark Bay bottlenose dolphins to understand how the fission-fusion society facilitates preferred associations and emergence of social network properties that influence fitness.
Sexual aggression in mammals
In non‐human mammals, sexual conflict should be particularly intense because males rarely provide parental care. An expected consequence of sexual conflict is male aggression towards mates.
Sex-specific variation in conspecific-acquired marking prevalence among dusky dolphins (Lagenorhynchus obscurus)
Dusky dolphins off Kaikoura, New Zealand, derive most of the notches and scars on their dorsal fins from conspecifics, and if injurious interactions are associated with intrasexual competition among males but not females, it is predicted males would have more Conspecific-acquired markings than females.
Selective aggressiveness in European free-tailed bats (Tadarida teniotis): influence of familiarity, age and sex
The results confirm that T. teniotis is able to discriminate between familiar and stranger individuals, showing higher rates of aggressive behaviours towards the latter, and predicts fewer aggressive events and more amicable encounters between colony mates than between strangers.
Aggressive Behaviors of Adult Male Atlantic Spotted Dolphins: Making Signals Count during Intraspecific and Interspecific Conflicts
The increased use of a more overt and energy intensive Behavioral Type, Pursuit, suggests that Atlantic spotted dolphins altered their behavior during aggressive encounters with bottlenose dolphins to compensate during fights with a larger species and/or to effectively communicate with a different species.
Every scar has a story: age and sex-specific conflict rates in wild bottlenose dolphins
The healing time of conspecific tooth rakes in wild bottlenose dolphins, a demographic profile of injury risk in the population, and patterns of age- and sex-specific received aggression are investigated to contribute to the understanding of the relationship between social conflict and life history strategies in long-lived mammals.


Ranging and association patterns of paired and unpaired adult male Atlantic bottlenose dolphins, Tursiops truncatus, in Sarasota, Florida, provide no evidence for alternative male strategies
Previous studies of Atlantic bottlenose dolphin, Tursiops truncatus, social structure near Sarasota, Florida, revealed two distinct patterns of ranging and association among paired and unpaired adult
A quantitative assessment of dominance relations among bottlenose dolphins
Zoo-based research revealed patterns of behavior that conformed to current knowledge about bottlenose dolphin social structure and facilitated development of a quantitative technique that can be used to assess cetacean dominance relationships in field research.
Sexual Behavior of Male Northern Elephant Seals: I. Lethal Injuries To Adult Females
Based on the observed incidence of female mortality in relation to females present on the rookery, the probability of a female being killed by a male during the breeding season is about one in a thousand; females are expected to evolve adaptations to reduce injurious encounters with males.
Female reproductive success in bottlenose dolphins (Tursiops sp.): life history, habitat, provisioning, and group-size effects
Examination of factors influencing female reproductive success in wild Indian Ocean bottlenose dolphins in Shark Bay, Australia finds shallow water may allow mothers and calves to detect and avoid predatory sharks.
Evidence for infanticide in bottlenose dolphins: an explanation for violent interactions with harbour porpoises?
It is suggested that infanticide must be considered as a factor shaping sociality in this and other species of cetaceans, and may have serious consequences for the viability of small populations.
Sexual selection in Japanese macaques I: female mate choice or male sexual coercion?
In a confined group of Japanese macaques, Macaca fuscata fuscatahoused, behavioural and endocrine data were combined to assess the validity of several mate-choice behaviours and the potential influence of sexual coercion, and a tentative model of mate choice for this species is proposed.
Patterns of Female Attractiveness in Indian Ocean Bottlenose Dolphins
In Shark Bay, Western Australia, it is documented for the first time patterns of female attractiveness that may correspond to multiple oestrous cycles, supporting predictions of a promiscuous mating system in bottlenose dolphins.
Sex Differences in Patterns of Association Among Indian Ocean Bottlenose Dolphins
Patterns of association among bottlenose dolphins resident in Shark Bay, Western Australia were analyzed using party membership data and found male-female associations were generally inconsistent and depended in part on female reproductive state.
Sex ratio and maternal rank in wild spider monkeys: when daughters disperse
Data from a long-term field study of the spider monkey, Ateles paniscus, in Peru indicate that a strongly female-biased sex ratio exists from birth in this population and two possible mechanisms of sex-ratio adjustment are discussed.
