Mate choice can be sensitive to social cues from neighboring individuals, e.g., animals can copy mate choice decisions. Males that are at risk of being copied by others may respond to this with reduced preference expression ("audience effects"). We review the various pathways by which sperm competition risk affects (1) male mate copying behavior and (2) audience effects. For example, a recent study suggests that males gather complex social information on rivals' sexual competitiveness (sexual activity and attractiveness to females) and respond with reduced expression of mating preferences only "when it matters," i.e., when a sexually competitive rival is present.
配偶选择可能对来自邻近个体的社会线索敏感,例如,动物可以模仿配偶选择决定。有被其他个体模仿风险的雄性可能会通过减少偏好表达来对此做出反应(“观众效应”)。我们综述了精子竞争风险影响(1)雄性配偶模仿行为和(2)观众效应的各种途径。例如,最近的一项研究表明,雄性会收集关于竞争对手性竞争力(性活动和对雌性的吸引力)的复杂社会信息,并且仅在“重要的时候”,即当存在性竞争力强的对手时,才会通过减少交配偏好的表达来做出反应。
