摘要: 类固醇激素睾酮是影响鸟类繁殖最重要的性激素之一,与鸟类的繁殖行为的各个方面息息相关。睾酮通过影响鸟类的羽色、鸣声等来影响鸟类的配偶选择,同时睾酮可以调节配偶选择和繁殖投入之间的平衡。睾酮水平影响出雏数、出飞数、孵化率成功率等繁殖成效。睾酮还对个体的免疫活性和个体的存活率等产生影响。目前关于睾酮对鸟类繁殖影响的研究大多是通过外源性植入睾酮的方式来改变个体睾酮的浓度,其研究结果也常出现相互矛盾之处,对于自然状态下影响睾酮水平变化的因素尚缺乏了解,睾酮对雌雄鸟在繁殖过程中的影响也不尽相同,有必要继续深入研究。

Abstract: Steroid hormone testosterone is one of the most important sex hormones affecting bird reproduction, which is closely related to breeding behavior. Testosterone affects sexual selection by changing feather color, song and so on. Meanwhile, testosterone could regulate the tradeoff between sexual selection and reproductive input. Testosterone affects reproductive efficiency, including nestling size, fledging size, and hatching success rate. Testosterone also affects the immune activity and survival rate of individuals. Most studies of bird breeding are based on exogenous implantation of testosterone. The results from literature had no consensus. The changes of testosterone level under natural conditions and the influencing factors are not well understood. The effects of testosterone on the reproductive process differed between male and female birds. Further studies on the effect of testosterone on breeding birds are critically needed.
