摘　　要：氧化应激是介导鸟类生活史权衡的重要生理机制,与鸟类繁殖的关系密切且复杂。氧化应激作为内在的生理机制,参与调节鸟类第二性征的表达、精子质量及繁殖投入,并在一定程度上预测繁殖成效与雏鸟的生长。而繁殖行为会影响亲鸟的氧化应激水平,造成个体氧化应激状态变化。然而,目前的研究多集中于成鸟的行为差异,缺乏深入机制的研究。充分了解氧化应激对鸟类繁殖行为的内在调控机制,以及这些机制如何与不断变化的环境协同进化,是非常重要的,需要进行深入的思考与探究。Oxidative stress is an important physiological mechanism mediating life-history trade-offs in birds,which is closely related to bird reproduction.Oxidative stress can affect avian mate choice through modulating the expression of sexual characteristics and sperm quality,mediate the trade-off between reproduction investment and self-maintenance,and predict reproduction success and chick growth.In turn,reproduction investment affects the level of oxidative stress.Most studies focus on behavioral exploration,and few are available for in-depth mechanism studies.It is important to fully understand the regulatory mechanisms of oxidative stress on bird reproductive behaviors and how these mechanisms co-evolve with changing environments.These all require in-depth thinking and exploration.
