摘　　要：生殖抑制指原本具有生育能力的动物个体因特定外界环境或生理条件而减少或丧失生殖能力的现象,有时是受环境变化的主动调控,更多的是出现在其他个体影响下的被动抑制,极端情况发生在社会性动物的永久性抑制,即永久无法生殖或无法生殖成熟。研究发现非社会性动物也有生殖的推迟及可恢复性的生殖抑制,生殖抑制影响着动物种群数量动态、维持和进化。随着多学科的发展,生殖抑制机理研究取得了诸多进展。从阐述生殖抑制的概念出发,解析生殖抑制的形态、激素和分子生理特征,总结了生殖抑制的原因、作用,终述现有的理论模型以及不同物种方面的最新进展,并就生殖抑制在生物资源管理方面的应用价值进行了展望,旨在丰富生殖抑制的理论,扩展应用实践,为后续的生物资源管理提供理论参考。Animals have evolved diverse reproductive strategies under the influence of abiotic and biological factors.Reproductive suppression is an adaptive strategy in animal reproduction.Reproductive suppression affects the success and efficiency of animal reproduction,which in turn affects the survival,population continuation and evolution of animals.With the development of multiple disciplines,there have been new advances in the study of reproductive suppression.There are many related studies on reproductive suppression abroad,and its importance in animals has been widely recognized,but the domestic research on reproductive suppression is insufficient.Thus,this paper firstly explains the basic concept and function of reproductive suppression.Reproductive suppression refers to the inhibition or damage to the normal reproductive development,reproductive physiology,or reproductive behavior of animals due to the impact of specific environment factors(including light,temperature,rainfall and food resources)or their own condition factors(population density,social rank,hormone),which makes animals reduce or lose their reproductive capacity.Reproductive suppression is one of the reproductive strategies that can benefit animals.It can reduce animal competition for resources by limiting population densities and by reducing direct competition for mates,resources,or territories and reduce animal offspring's competition for resources,mates,or territories.By recruiting non-reproductive alloparents and/or monopolizing on parental care from conspecifics,a suppressed female can benefit by avoiding reproduction when it is unlikely to be successful(e.g.,high levels of competition or infanticide).It also can adjust the dynamic balance of animal population.Secondly,the theoretical models of reproductive suppression such as dominance control model,self-restraint model and incomplete control model,reproductive suppression modes including behavioral suppression and physiological suppression,mechanism of reproductive suppression,and the effect
