One individual's actions may affect the evolutionary fitness of another individual. Sexually antagonistic coevolution occurs when one partner's behavior decreases the fitness of the other partner (Rice, 1996). This conflict pressures the other partner to counter these disadvantageous actions. Mate guarding is a mate retention tactic aimed at keeping a partner from cheating. Mate guarding may re...

The extent and importance of female mate fidelity in polygynous mating systems are poorly known. Fidelity may contribute to high variance in male reproductive success when it favors attractive mates or may stabilize social interactions if females are faithful to mating sites rather than males. Using 12 years of data on genetic mate choice in the cooperatively lekking lance-tailed manakin (Chiro...

A computational study is conducted to evaluate the hypothesis that mate selection is the evolutionary origin of communication. A population of neural networks is evolved for two cooperative tasks mate selection and prey capture. Simple codes developed for mate selection serve as an effective stepping stone for prey capture but not vice versa. Mate selection followed by an additional prey captur...

Multidrug and toxic compound extrusion (MATE) transporters are a family of cation antiporters occurring in most organisms from prokaryotes to eukaryotes. This family constitutes one of the largest transporter families in plants, with, for example, more than 50 MATE genes in the Arabidopsis genome. Moreover, MATE transporters are involved in a wide variety of physiological functions throughout p...

Mate-guarding is an important determinant of male reproductive success in a number of species. However, it is known to potentially incur costs. The aim of the present study was to assess the effect of mate-guarding on male physiological stress and aggression in long-tailed macaques, a species in which males mate-guard females to a lesser extent than predicted by the Priority of Access model (Po...

marriage and mate selection is one of the most important events in the social life which has been observed in various forms in different eras and societies. to achieve this, using qualitative content analysis, all marriages mentioned in the shahnameh were analyzed. the results show that the kings and heroes as the class of iranian society in the shahnameh, for finding a matching partner, person...
