Long-term committed mating is a fundamental strategy in the human repertoire. Successful enactment of this strategy requires solving two related adaptive problems--fending off potential mate poachers and preventing a mates from defecting. Mate guarding adaptations evolved to solve these persistent problems. Those who failed in mate guarding risked suffering substantial reproductive costs rangin...
Sexual selection through female mate choice for genetic characteristics has been suggested to be an important evolutionary force maintaining genetic variation in animal populations. However, the genetic targets of female mate choice are not clearly identified and whether female mate choice is based on neutral genetic characteristics or on particular functional loci remains an open question. Her...
Human mate choice is central to individuals' lives and to the evolution of the species, but the basis of variation in mate choice is not well understood. Here we looked at a large community-based sample of twins and their partners and parents ([Formula: see text] individuals) to test for genetic and family environmental influences on mate choice, while controlling for and not controlling for th...
BACKGROUND: In mare, different methods of earlier cyclicity induction and hastening first ovulation of the year have been reported. OBJECTIVES: The goal of present study was to investigate the effect of progesterone (Cue-mate®) on synchronization and acceleration the first ovulation of the year in winter anestrous mares under artificial lighting system. METHODS: After detection of anestrus mare...
Mate recognition is the process of identifying and assessing appropriate species, sex or population another individual for their suitability as a potential mate. Recognition may be innate learned. Learning, acquisition knowledge skills through experience, involves relatively long-term change in behavioral responses. In this study we examined learned mate invasive male mosquitofish, Gambusia hol...
Male mate choice has been reported in the fruit fly, Drosophila melanogaster, even though males of this species were previously thought to maximise their fitness by mating with all available females. To understand the evolution of male mate choice it is important to understand variation in male mating preferences. Two studies, using different stock populations and different methods, have report...
As a generalization of the triple I method, the universal triple Imethod is investigated from the viewpoints of both fuzzy reasoningand fuzzy controller. The universal triple I principle is putforward, which improves the previous triple I principle. Then,unified form of universal triple I method is established based onthe (0,1)-implication or R-implication. Moreover, the reversibilityproperty o...
Article history: Received 16 February 2016 Received in revised form 19 July 2016 Accepted 20 July 2016 Available online xxxx Leaving onemating relationship and entering another, serialmating, is commonly observed inmany cultures. An array of circumstances can prompt a mate switch. These include (1) unanticipated costs inflicted by one's mate, or ‘relationship load,’ not apparent on the initial ...
