鸟类鸣声与个体适合度关系的研究进展

鸣声蕴藏着丰富的生物学信息,是鸟类间信息交流最主要的方式之一。本文综述了鸟类鸣声行为与包括个体状态(体征、激素水平和健康状况)、社会等级及繁殖(性选择和成效)在内的个体适合度关系的研究进展。文章总结发现,鸟类的鸣声水平与单一体征参数关系的研究结果不稳定,鸣声可能受个体内部的多种激素调控,并与个体的社会等级有直接关系。雌雄个体鸣声均与繁殖有一定相关性,但双亲鸣声行为策略存在差异。鸣声对繁殖适合度的影响受到其他因素如物种、婚配制度等因素的影响。鸟类鸣声代表的生物学信息是个体身体质量的综合体现,与鸟类个体适合度的关系较为复杂。为解释鸣声所代表的生物学信息,需要从适合度的多个角度(社会等级、身体状况和繁殖情况等)来考虑多种鸣声参数。

Research Progress on the Relationship between Bird Vocalization and Individual Fitness

Birds use sounds to communicate,and large amounts of information are transmitted by vocalizations.We summarized the current research progress on the relationship between bird vocal behavior and individual fitness including individual status(physical parameters,hormone levels and health conditions),social status and reproduction(sexual selection and breeding success).We found that the relationships between song traits and single physical parameter were different according to the traits examined.Bird vocalization could be regulated by various hormones,and related with the individuals'social ranks.Both male and female songs are related with reproduction,but there are differences in the strategies of parents’vocal behavior.The effect of vocalization on reproductive fitness is also influenced by other factors,such as taxa and mating system.The biological information represented by bird vocalization is a comprehensive manifestation of individual body condition,and its influence on individual fitness is more complicated.In order to interpret the biological information represented by vocalizations,we need to consider multiple parameters from multiple prospects,such as social grade,physical condition and reproduction.
