Abstract. Orangutan males demonstrate intrasexual dimorphism with corresponding alternative mating strategies. Sexual harassment is the predominant feature of the mating strategy that subadult males pursue. This study investigated the countertactics that females employ to reduce sexual harassment by subadult males. I observed 207 copulations during more than 9,000 h of focal follows of wild Sumatran orangutans at the Suaq Balimbing Research Station over a 23-month period. Rates of copulations… 

Female reproductive strategies in orangutans, evidence for female choice and counterstrategies to infanticide in a species with frequent sexual coercion

The results support the hypothesis that, together with concealed ovulation, facultative association is a mechanism of female choice in a species in which females can rarely avoid coercive mating attempts and female resistance, which reduced copulation time, may provide an additional mechanism for mate selection.

Sexual conflicts in spotted hyenas: male and female mating tactics and their reproductive outcome with respect to age, social status and tenure

Female mate choice matched observed patterns of affiliative male–female behaviour, indicating that affiliative behaviour is a successful male mating tactic, and was consistent with the idea that male tenure may serve as an index of male quality, although male fertility may decline with extreme old age.

Female aggregation and male competition reduce costs of sexual harassment in the mosquitofish Gambusia holbrooki

It was found that sexual harassment more than halved the foraging efficiency of the female in a task requiring the retrieval of food items scattered on the water surface, and the presence of shoalmates relieved the female from harassment and foraging Efficiency increased with the number of females in the group.

The results are consistent with the hypothesis that sexual coercion is an important component of male chimpanzee mating strategies in many sociodemographic circumstances, but also show that male tactics vary both in response to and independently of those circumstances.

Sexual harassment in a live-bearing fish (Poecilia mexicana): influence of population-specific male mating behaviour

The sexual activity of cave mollies did not correlate with male body size in any experiment, indicating that even after sexual deprivation, small cave molly males do not switch to the “alternative” mating behaviour known in surface-dwelling P. mexicana, where sexual activity is correlated negatively withmale body size.

Sexual harassment and female gregariousness in the South American sea lion, Otaria flavescens

The behaviour of dominant males and their females in a breeding colony of Otaria flavescens was analysed to investigate the relationship between male harassment and female gregariousness in relation to the size of breeding groups.

The cost of associating with males for Bornean and Sumatran female orangutans: a hidden form of sexual conflict?

It is found that the cost of association, in terms of reduced feeding to moving ratio and increased time being active, is higher in the less sociable Bornean population, and male-maintained associations are an expression of sexual conflict in orangutans, at least at Tuanan.

Potential female mate choice in a male dominated system: the female capybara, Hydrochoerus hydrochaeris

It is shown that the original assumption of male hierarchy as the main mechanism of reproductive distribution is incomplete, and female mate choice plays an important role in determining which males reproduce.

Are Male Orangutans a Threat to Infants? Evidence of Mother–Offspring Counterstrategies to Infanticide in Bornean Orangutans (Pongo pygmaeus wurmbii)

Long-term behavioral data collected from Bornean orangutans in Gunung Palung National Park, Indonesia are used to test whether the sexual selection hypothesis for infanticide helps explain aspects of orangutan social behavior and suggest thatinfanticide by males is a selective pressure shaping female orangUTans social behavior.

During a four‐year period at Tanjung Puting Reserve, Central Indonesian Borneo, subadult males were observed for 670.5 observation hours, 463 hours of which were as focal individuals, and much subadult male sociality can be understood in terms of male‐male competition for females.

The evolution of ungulate leks

It is suggested here that, in lek-breeding ungulates, mating on clustered territories may have other benefits to both sexes, and males are likely to benefit by holding clustered territories because these both attract and retain receptive females more effectively than solitary territories.

Forced Copulation in Waterfowl

As HEINROTH suggested, FC probably does not occur in swans, most geese and shelducks because it is incompatible with the major roles that paired males play in defence of breeding territories, mates, nest-sites and broods in these groups.
