Costs of mating effort can affect the reproductive strategies and lifetime fitness of male primates, but interspecific and interindividual variation in the magnitude and distribution of costs is poorly understood. Male costs have primarily been recognized in seasonally breeding species that experience concentrated periods of mating competition. Here, we examine foraging costs associated with male mating effort in chimpanzees (Pan troglodytes schweinfurthii), a polygynandrous species, in which… 
Individual, social, and sexual niche traits affect copulation success in a polygynandrous mating system
TLDR
The results suggest that hyraxes choose mating partners from their available mate pool (or sexual niche) taking into account the traits of their actual mates, other potential mates, and those of their competitors.
Energetic management in wild chimpanzees (Pan troglodytes verus) in Taï National Park, Côte d’Ivoire
TLDR
It is found that the energetics of both males and females are related to ecological factors, such as food availability, however, female energy balance appears also to be related to increased male mating competition, as this can result in increased aggression directed from males to females, with apparent energetic costs for females.
The High Price of Success: Costs of Mating Effort in Male Primates
TLDR
This special issue features contributions investigating the costs of male mating effort across primate species, addressing the specific types of mating effort expected for male primates and the significance of these costs for the understanding of primate life histories and socioecology.
Effect of female group size on harem male roosting behavior of the Indian short-nosed fruit bat Cynopterus sphinx
TLDR
It is suggested that having a larger harem may indeed be costly for the males by reducing their foraging time, as well as positively and significantly correlated with female group size.
Dominance rank and the presence of sexually receptive females predict feces-measured body temperature in male chimpanzees
TLDR
Fecal temperature is a reliable proxy for core body temperature in large-bodied mammals, captures metabolic costs associated with male mating behavior, and represents a valuable noninvasive tool for biological field research.

TLDR
It is shown that maximum entropy species distribution modeling can be used to successfully predict small-scale variation in the distribution of 24 important plant food species for chimpanzees at Gombe National Park, Tanzania and that nonswollen females selected the highest-quality habitats compared with swollen females or males, in line with predictions based on their energetic needs.
The cost of associating with males for Bornean and Sumatran female orangutans: a hidden form of sexual conflict?
TLDR
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, at least at Tuanan, and association maintenance qualifies as another expression of sexual conflict in orangutans.
Reproduction is costly in an infected aquatic insect
TLDR
The results suggest that the costs of reproduction are higher in infected males, which may affect reproductive investment and sexual selection.

TLDR
It is demonstrated that mate guarding in the 1st-ranking male is a high-cost mating tactic, while opportunistic mating in subordinate males is a low- cost mating tactic.
Male Mating Interest Varies with Female Fecundity in Pan troglodytes schweinfurthii of Kanyawara, Kibale National Park
TLDR
The hypothesis that male chimpanzees have the ability to assess the profitability of mating attempts is supported, a trait that may act as a counter-adaptation to female strategies to obscure paternity.
Energetic Costs of Reproductive Effort in Male Chimpanzees
TLDR
This dissertation contributes to the understanding of UCP as an energy assay by validating the application of U CP for assessing dietary quality in bonobos (Pan paniscus) at Kokolopori, DRC and providing a detailed assessment of diurnal variation in UCP levels in relation to short-term changes in food intake in chimpanzees at Kanyawara, Kibale NP, Uganda.
Costs of mating competition limit male lifetime breeding success in polygynous mammals
TLDR
Cross-species comparisons are used to investigate the correlates of breeding lifespan in male mammals and show that male breeding lifespan depends on the extent of polygyny, which reflects the relative intensity of competition for access to females.

TLDR
While dominance ranks of the adult males showed no consistent correlation with involvement in the restrictive mating patterns, it was clear that the most dominant male did gain an advantage and was the only male able to monopolise oestrous females by showing possessive behaviour.

Sex differences in survival costs of reproduction in a promiscuous primate
TLDR
The findings provide the first evidence of sex differences in the survival costs of reproduction in nonhuman primates and suggest that reproduction has significant fitness costs even in environments with abundant food and absence of predation.
Foraging time of rutting bighorn rams varies with individual behavior, not mating tactic
TLDR
Compared to expectation, individual rams observed both coursing and tending spent less time foraging when coursing than when tending, indicating that males either modify their behavior according to available metabolic reserves or adjust the energy devoted to rutting activities to the level of expected benefits.
