In ungulates, rank order is determined by differences in weight, body size, weapon size and age. In the Caprini tribe (Bovidae: Caprinae), adult male Himalayan tahr are unique to show different coat colours, but no sexual dimorphism in weapons. A highly significant correlation between hair colour and rank order was found during the rut: males with a lighter coloured ruff dominated over darker ruffed ones, in both aggressive interactions and access to oestrus females. We studied colour-based… Expand
Male ruff colour as a rank signal in a monomorphic-horned mammal: behavioural correlates
TLDR
The social behaviour of male Himalayan tahr is investigated and the relationships between ruff colour, courtship and agonistic behaviour patterns during the rut are analyzed. Expand
Relationships between male giraffes’ colour, age and sociability
TLDR
It was found that males did not all darken at the same rate or to the same degree, and colour variation increased with age, which suggests that colour is not solely an age-based trait but could be a secondary sexual trait. Expand
Face markings in Northern chamois: cues of dominance?
TLDR
The results offer some first insights into the potential correlates of chamois facial mask, suggesting that face markings might provide age-specific cues of mass-based dominance in females, while their role in males appears more uncertain. Expand
On the Behavioural Biology of the Mainland Serow: A Comparative Study
TLDR
An evolutionary comparison across Caprinae species with unritualised piercing horns, inclusive of serows, suggests that inter-sexual direct forms of aggressive behaviour are used significantly more often than indirect ones, except for chamois, confirming Rupicapra spp. Expand
Male mating competitiveness and age-dependent relationship between testosterone and social rank in bighorn sheep
TLDR
Testosterone may be related to male’s ability to compete for mates through its relationship with behaviors determining social rank, rather than by influencing the development of morphological traits. Expand
Reproductive timing in a lekking mammal: male fallow deer getting ready for female estrus
TLDR
It is argued that males move to the lek early because they need to engage in male–male interactions and scent-marking activities, and that adult males seeking for a chance to defend the territory and mate have to move early and stay there until the end of the rut, though this does not guarantee them a higher mating success. Expand
Vocalizations by Alaskan moose: female incitation of male aggression
TLDR
Results indicate that female moose gave protest moans to reduce harassment by smaller males, and assure a mating opportunity with the most dominant male, a subtle mechanism of indirect mate choice by females in other vertebrates in which choice is limited by a mating system in which male–male combat and male dominance over females reduces opportunities for female choice. Expand
Coat color and its effect on preference for the scent marks of opposite-sex conspecifics in the meadow vole Microtus pennsylvanicus
TLDR
The data suggest that blond females who are already conspicuous to predators, may select blond males as mates because these conspicuous males have survived to mate they may have good genes that reflect their relatively higher quality. Expand
Mammalian sexual dimorphism.
TLDR
The aim of this review is to discuss current knowledge relating to the evolution, benefits and costs of mammalian sexual dimorphisms and, where possible, draw conclusions that might be beneficial for the husbandry and propagation of mammals today. Expand
Lekking in fallow deer ( Dama dama ): a long walk to territoriality
TLDR
Results of a long-term study performed in the lekking fallow deer population of San Rossore, Italy, where data were collected through radio-tracking and direct observations showed that the actual position of the leK is handy with regards to female travel costs and predation risk avoidance, in accordance to the female preference and predator avoidance hypotheses.

Sexual Differences in Aggressive Behaviour of the Apennine Chamois
TLDR
Sexual differences in patterns of aggressive behaviour may be related to the different gregariousness of females and males, probably influenced by resource availability in the habitats they use. Expand
Clues for dominance in female chamois: Age, weight, or horn size?
TLDR
A study of social interactions among female Apennine chamois Rupicapra pyrenaica ornata was made in Abruzzo National Park, central Italy, between 1981 and 1982 and suggests that body weight may be the most important attribute. Expand
Sexual selection and social rank in bighorn rams
TLDR
By providing evidence that mass is an important determinant of rank, this study supports the contention that sexual selection leads to high sexual dimorphism in this species. Expand
Social mediation of sexually selected ornamentation and steroid hormone levels in male junglefowl
TLDR
The results are consistent with social mediation of comb size and testosterone and corticosterone levels, but it is unclear whether these hormones contribute to the observed social limitation of comb length. Expand
Sexual size dimorphism in fallow deer (Dama dama): do larger, heavier males gain greater mating success?
TLDR
It is concluded that larger mature fallow bucks have advantages over other males when competing for matings, and sexual selection therefore continues to act on sexual size dimorphism in this species. Expand
Overt and covert competition in a promiscuous mammal: the importance of weaponry and testes size to male reproductive success
TLDR
The Soay sheep mating system is characterized by male contests for mating opportunities and high female promiscuity and it is found that greater horn length, body size and good condition each independently influence a male' ability to monopolize receptive females. Expand
Testosterone is involved in acquisition and maintenance of sexually selected male plumage in superb fairy-wrens, Malurus cyaneus
TLDR
The evidence suggests that development of the nuptial plumage is testosterone dependent, although it cannot exclude that testosterone exerts its action after conversion to a metabolite such as oestrogen. Expand
Sexual Selection, Temperature, and the Lion's Mane
TLDR
The mane of the African lion is a highly variable trait that reflects male condition and ambient temperature, and phenotypic plasticity suggests that the mane will respond to forecasted increases in ambient temperature. Expand
An experimental study of male adornment in the scarlet-tufted malachite sunbird: I. The role of pectoral tufts in territorial defence
TLDR
The results indicate that the pectoral tufts of male scarlet-tufted malachite sunbirds are used as a means of male-male assessment during aggressive interactions. Expand

TLDR
The rutting behaviour of the Himalayan goral appears to be more closely related to that of Oreamnos (in quality and quantity of behaviour patterns, as well as the mating system) than that ofCapricornis. Expand
