Abstract:
Abstract Same-sex sexual behaviors do not have direct fitness outcomes, but might be adaptive. This issue is often discussed in group-living animals, where social bonding is crucial. In our captive environment, around 33% of the Java-sparrow (Lonchura oryzivora) males kept in unisex cages have stable bonded partners. Those bonded males often perch side by side and show allopreening and joint-defensive behaviors towards others. In this study, we aimed to determine how males including such same-sex bonded individuals communicate with each other via vocalizations. We introduced same-sex pairs of

Abstract:
Female preferences for male body size, male preferences for female body size, and male–male interactions were experimentally evaluated in zebrafish (Danio rerio) obtained from the pet trade. Female preferences were shown for larger males. Males did not show preferences for female body size. Zebrafish males have strong interactions when two males are placed together with a female. Body length of males and females was not different. These results indicate that the reproductive strategy of zebrafish is more elaborate than simply broadcast spawning: females are choosy and males compete for females

AbstractNatural and sexual selection often act in opposing directions, forcing individuals to prioritize activities necessary for survival with those required for reproduction. We examined the interaction of natural and sexual selection pressures on the behaviour of beaugregory damselfish, Stegastes leucostictus, by presenting territorial males with an egg predator and either a male or female conspecific, requiring males to prioritize brood defense with either courtship or intra-sexual competition.

Abstract:
Recent experiments indicate that male preferential harassment of high-quality females reduces the variance in female fitness, thereby weakening natural selection through females and hampering adaptation and purging. We propose that this phenomenon, which results from a combination of male choice and male-induced harm, should be mediated by the physical environment in which intersexual interactions occur. Using Drosophila melanogaster , we examined intersexual interactions in small and simple (standard fly vials) versus slightly more realistic (small cages with spatial structure) environments.

AbstractAffiliative and cooperative relationships are not common among mammalian males. This may be partly the result of sexual selection which favors competitive and agonistic interactions among mature males, and partly the result of the fact that female mammals are generally philopatric. This means that adult males usually live among unrelated and unfamiliar individuals. Bonnet macaques (Macaca radiata) represent one of several exceptions to this general pattern. Adult males in this species frequently sit together, groom, huddle, greet, and support one another. The nature of social relations

This variation in female behaviour is predicted to affect the pattern of selection on males, with intense pre-copulatory sexual selection under monandry compared to a mix of pre- and post-copulatory forces affecting fitness under polyandry. We tested the hypothesis that differences in female mating biology would be reflected in different costs of pre-copulatory competition between males. We observed that exposure to

Abstract:
Secondary sexual traits, such as specific body parts or colouration, play an important role in mating interactions. It has been proposed that they function as quality indicators driven by sexual selection. In birds, much attention has been paid to the study of feather pigmentation, especially in diurnal passerines. However, recent research demonstrates that structural achromatic colours are likely to be of similar importance for communication, especially for species inhabiting poorly lit environments and that are active at night. Using 15 years of capture–recapture data from a long-term study

Abstract:
AbstractMale aquatic warblers are relatively unusual in producing three different song structures, A, B and C. The shorter A-B songs have been shown to function in male-male aggressive interactions, and it was speculated that the longer and more complex C songs might function in female attraction. The present playback experiments were carried out on hormone-implanted females in a large, experimental aviary. When playback was of a male singing C songs, females were attracted faster and for longer periods than when the same male produced A-B songs. Females gave relatively few sexual displays, bu

Abstract:
Sexual dysfunction is a common, underappreciated complication of diabetes. Male sexual dysfunction among diabetic patients can include disorders of libido, ejaculatory problems, and erectile dysfunction (ED). All three forms of male dysfunction can cause significant bother for diabetic patients and can affect their quality of life. Diabetic patients take oral hypoglycemic drug to control their diabetic as well as take herbal sex stimulants to control to increase the libido. The combined use of herbs and drugs has increased the possibility of herb-drug interactions. The study was undertaken to

Abstract:
Mate competition provides the opportunity for sexual selection which often acts strongly on males, but also the opportunity for sexual conflict that can alter natural selection on females. Recent attention has focused on the potential of sexual conflict to weaken selection on females if male sexual attention, and hence harm, is disproportionately directed towards high- over low-quality females, thereby reducing the fitness difference between these females. However, sexual conflict could instead strengthen selection on females if low-quality females are more sensitive to male harm than high-qua

Abstract:
Several hypotheses concerning factors that favour coexistence of female morphs in damselflies (Zygoptera: Odonata) invoke differential attraction to (or harassment of) female morphs from mate-searching males. We designed experiments to determine whether males were differentially attracted to either of two discrete female morphs in a damselfly, Nehalennia irene (Hagen). One female morph was similar in colour and pattern to the conspecific male ("androchrome") and the other was dissimilar ("gynochrome"). Males were indiscriminate in their mating attempts.

Abstract:
To experimentally assess if a male sexual trait has an influence on female choice and (or) male-male competition, it is essential to separate these two evolutionary forces. Female choice may be obscured by the overriding influence of male-male competition, and it may therefore appear that female interests coincide with male dominance. We approached this problem using the threespine stickleback, Gasterosteus aculeatus, by leashing the males, allowing the female to fully interact and mate with each male, while physical interactions between the males were prevented. Our results show that in this

The female sex doll allows for the projection of uninhibited sexual fantasy and is animated through that fantasy in the mind of her partner. In this way, she can be seen to function as a performative effigy of desire, maintaining heteronormative male sexuality by reflecting a patriarchal ideal of female physicality and objectification while simultaneously demanding a responsive performance of heterosexual masculinity. In the film Lars and the Real Girl, the relationship between the female sex doll and her male partner is shifted into the public sphere, and Lars projects a social, rather than s

Sex differences in lifespan are ubiquitous, but the underlying causal factors remain poorly understood.

To address this problem, we genetically manipulated the sexual identity of the nervous system—and hence sexual behaviour—in Drosophila melanogaster , and measured lifespan under varying social conditions.

In this research, I draw from 22 in-depth interviews with male exotic dancers and 18 months of fieldwork at a strip club to examine the extent to which male strippers experience “the toll” of exotic dance. Specifically, I focus on dancers’ interactions with customers, their experiences with stigmas, the impact stripping has on their romantic relationships, how they negotiate boundaries with patrons, and the conseque

Males figured more prominently than females in Darwin's view of sexual selection. He considered female choice of secondary importance to male–male competition as a mechanism to explain the evolution of male ornaments and armaments. Fisher later demonstrated the importance of female choice in driving male trait evolution, but his ideas were largely ignored for decades. As sexual selection came to embrace the notions of parent–offspring and sexual conflict, and experimental tests of female choice showed promise, females began to feature more prominently in the framework of sexual selection theor

AbstractObservations of a free-living population of Bosca's newt, Triturus boscai, show that courtship behaviour in nature is similar to the behaviour observed in earlier laboratory studies. Complementary evidence was obtained on the behaviour called flick, which is sometimes inserted at the end of the static display phase, and may be viewed as an equivalent behaviour to the retreat display of the other small-bodied newt species. Sexual interference in the natural population was mainly caused by males. Two characteristic male behaviour patterns were recognised, the waiting position and the pus

Abstract:
Male homosexual behaviour—although found in most extant clades across the Animal Kingdom—remains a conundrum, as same-sex mating should decrease male reproductive fitness. In most species, however, males that engage in same-sex sexual behaviour also mate with females, and in theory, same-sex mating could even increase male reproductive fitness if males improve their chances of future heterosexual mating. Females regularly use social information to choose a mate; e.g. male attractiveness increases after a male has interacted sexually with a female (mate choice copying). Here, we demonstrate tha
