Relationship between sexual interactions and the timing of the fertile phase in captive female Japanese macaques (Macaca fuscata)
TLDR
It is found that there was no increase in female proceptive behaviors during the fertile phase of the ovarian cycle, suggesting that female behaviors did not clearly signal the probability of conception, and different males may have access to different signals of ovulation and/or are differentially restrained as to how they can act on that information.
Seasonal shifts in sociosexual behaviour and reproductive phenology in giraffe
Abstract Reproductive phenology (timing) is a heritable trait that confers a range of fitness or survival advantages. Giraffe ( Giraffa spp.) breed year-round; however, some studies have suggested

Changes in Social Interaction Adolescent Male Giraffes (Giraffa Camelopardalis) as they Shift from a Social to Solitary Lifestyle
Social interactions that result in preferential relationships between individuals have been observed in multiple species of mammals. Female mammals tend to stay in long-term associations with other
Androgen changes and flexible rutting behaviour in male giraffes
TLDR
It is confirmed that bulls indeed have unsynchronized rut-like periods, not unlike another tropical megaherbivore, the elephant, but on a much shorter timescale, and profound changes in male sexual and social activities at the scale of about two weeks.
Giraffe males have longer suckling bouts than females
TLDR
Male calves are more demanding for the amount of investment received and they are more successful in this effort than female calves, demonstrating the importance of sniffing for the identification of the suckling calf by the female.
Social Behavior in a Herd of Captive Male Giraffes
TLDR
In a herd of one adult (named Emba) and two subadult male giraffes (named Rafiki and Gage), the dominant adult giraffe, Emba, demonstrated sociosexual behavior—apparent courtship, investigation, and flehmen responses—almost exclusively toward one of the subadult giraffe, Rafiki, and agonistic behavior towards both subadult Giraffes.

Behavioral indices of estrus in a group of captive African elephants (Loxodonta africana)
This study investigated behavioral signals of estrus by systematically monitoring the interactions of one male with four female African elephants housed in a naturalistic outdoor enclosure at
The structure of social relationships among captive female giraffe (Giraffa camelopardalis).
TLDR
Affiliative interaction, proximity, and nearest neighbors for 6 captive female giraffe living in a large outdoor enclosure were analyzed, and all three measures were nonrandomly distributed, indicatingfemale giraffe had social preferences.
Oestrous Behaviour and Female Choice in the African Elephant
  • C. Moss
  • Biology, Environmental Science
  • 1983
TLDR
Observation of female behaviour during oestrus suggested that some females preferred to mate with males in the largest size class, particularly those in musth, and two possible short-term advantages to females exercising choice in mating partners are suggested.
Reproductive success in male savanna baboons
TLDR
It is suggested that mate selectivity, longevity, and stochastic factors are important components influencing male baboon reproductive success.
Reproductive cycle length and pregnancy in the southern white rhinoceros (Ceratotherium simum simum) as determined by fecal pregnane analysis and observations of mating behavior
TLDR
It is argued that these approximately monthly cycles represent the typical reproductive cycle for southern white rhinoceros and should be useful for captive breeding efforts for this threatened species.
Sexual segregation by Masai giraffes at two spatial scales
Summary In this paper alternative explanations for observed patterns of sexual segregation by giraffes are examined at two spatial scales: within-habitats and within-landscape. Habitats are
