“…This has also been considered in terms of incentive salience and the rewarding value of the potential mate [36][37][38]. Mate choice, which encompasses the appetitive phase, can be divided into two categories: preference (the preferential order of attractiveness in which an individual ranks potential mates) and choosiness (the responsiveness to potential mates and the amount of effort expended to assess the mate and make the choice) [19,39].…”

Animals are under constant threat of parasitic infection. This has influenced the evolution of social behaviour and has strong implications for sexual selection and mate choice. Animals assess the infection status of conspecifics based on various sensory cues, with odours/chemical signals and the olfactory system playing a particularly important role. The detection of chemical cues and subsequent processing of the infection threat that they pose facilitates the expression of disgust, fear, anxiety, and adaptive avoidance behaviours. In this selective review, drawing primarily from rodent studies, the neurobiological mechanisms underlying the detection and assessment of infection status and their relations to mate choice are briefly considered. Firstly, we offer a brief overview of the aspects of mate choice that are relevant to pathogen avoidance. Then, we specifically focus on the olfactory detection of and responses to conspecific cues of parasitic infection, followed by a brief overview of the neurobiological systems underlying the elicitation of disgust and the expression of avoidance of the pathogen threat. Throughout, we focus on current findings and provide suggestions for future directions and research.

Mate choice is an important cause of natural and sexual selection and drives the evolution and elaboration of male ornaments. Yet mate choice decisions are often neither consistent nor uniform, and a range of factors have been identified to influence variation between and within individuals. A potential source of variation influencing preferences and/or choosiness is animal personality, that is, repeatable among-individual differences in behaviors. Not only may individuals differ in average personality phenotype but also vary in how consistently they display said personality. Distinguishing between personality and consistency is important because both aspects are potentially naturally selected traits that may yet influence how sexually selected ornaments are evaluated. Here, we use a predator evasion assay to test whether there is variation in boldness among female gray treefrogs (Hyla versicolor), and then examine whether personality traits (spectrum of shy to bold) are correlated with choosiness for longer duration calls. We document substantial and repeatable between-individual variation in boldness, suggesting the presence of animal personality. Results also reveal that the consistency with which females expressed boldness is independent from average personality phenotype and that it is correlated with choosiness: more consistently bold females were choosier.
