Male primates in species with pronounced secondary sexual adornments can exhibit reversible or irreversible bimorphism, i.e., striking variation in the degree to which males express the adornments. Verreaux’s sifaka (Propithecus verreauxi verreauxi) use scent marking as a form of communication and exhibit sex differences in scent glands. Some males exhibit a pronounced brown staining around their sternal gland, whereas others do not. We studied morphological and behavioral characteristics of… 

Sexual Signalling in Propithecus verreauxi: Male “Chest Badge” and Female Mate Choice

It is reported that stained-chested males had a higher throat marking activity than clean-cheted males during the mating season, but not during the birth season, and it is found that females copulated more frequently with stained-Chested males than the clean- Chested males.

Patterns of male dispersal in Verreaux's sifaka (Propithecus verreauxi) at Kirindy Mitea National Park

The absence of a seasonal immigration pattern suggests that fluid group boundaries may allow mating success without establishment in a social group before the mating season, and it is suggested that coalitions may be used to improve competitive ability.

The lemur syndrome unresolved: extreme male reproductive skew in sifakas (Propithecus verreauxi), a sexually monomorphic primate with female dominance

It is shown that male reproductive success in ten groups of Verreaux’s sifakas was extremely skewed in favor of the dominant male over 9 years, and more than a third of all groups are effectively harem groups because only one male was unrelated to the resident female(s).

Male orang-utan bimaturism and reproductive success at Camp Leakey in Tanjung Puting National Park, Indonesia

It is concluded that orang-utan male bimaturism is consistent with an evolutionarily stable reproductive strategy and that reproduction within the range of a dominant, flanged male is highly skewed in his favour, while unflanged males may largely wait for reproductive opportunities.

Mate-Guarding as a Male Reproductive Tactic in Propithecus verreauxi

Sexual selection theory predicts that in group-living mammals, male reproductive tactics can lead to high reproductive skew in favor of dominant individuals. In sifakas (Propithecus verreauxi), a

Male reproductive skew in multimale social groups of Verreaux’s Sifaka (Propithecus verreauxi) at Kirindy Mitea National Park, Madagascar

Female reproductive strategies might hinder dominant males’ monopolization of matings and provide reproductive opportunities to non-dominant and extra-group males in a population of Verreaux’s sifaka living in Kirindy Mitea National Park, Madagascar.

Effects of dominance and female presence on secondary sexual characteristics in male tufted capuchin monkeys (Sapajus apella)

Measurements of secondary sexual characteristics in captive dominant and subordinate male tufted capuchin monkeys (Sapajus apella) with varying access to females found little evidence to suggest that alpha males advertise their status within all‐male groups via sexual secondary characteristics.

Group benefit associated with polymorphic trichromacy in a Malagasy primate (Propithecus verreauxi)

This work identified genetic evidence of polymorphic trichromacy in a population of Verreaux’s sifaka at Kirindy Mitea National Park in Madagascar, and explored effects of color vision on reproductive success and feeding behavior using nine years of morphological, demographic, and feeding data.

Is inbreeding avoidance driving female mate choice in Verreaux's sifaka lemurs?

It is concluded that inbreeding avoidance does not appear to be the main force driving female mate choice in Verreaux’s sifaka lemurs and explanations for these findings are addressed.

It is demonstrated that male-male competition and rank reversals have remarkable effects upon testicular function, secondary sexual traits, and behavior in the adult male mandrill.

It is presented the first evidence for sexual deception by female mimicry in birds, and it is shown that mimicry incurs a cost, that of increased aggression from females, which may explain why female-like males have reduced, mating success.

It is argued that while group size may be constrained by the availability of resources, group composition reflects the effects of small-sample demographic variations rather than the outcome of reproductive competition among or between males and females.

We propose that the female-like plumage worn by some male birds in their first potential breeding season has evolved to facilitate breeding when 1-yr old through the deception of older males. By
