Abstract

Summary. Timing of reproduction is a critical life-history trait and implies major fitness consequences. Differences in life history strategies can lead to different responses to the same environmental conditions even among closely related species. Investigating the factors affecting the timing of reproduction in closely related and sympatric species may help understanding the relationship between different life history traits and species-specific responses to ecological factors. We investigated the effects of season (photoperiod), local climatic variability and prey abundance on the breeding season of two sympatric insectivorous birds that differ in the timing of reproduction and moult and have different migration strategies: the Moustached Warbler Acrocephalus melanopogon and the Eurasian Reed-warbler Acrocephalus scirpaceus. During a five-year period, breeding phenology was determined by examining bird incubation patches during standardised captures and food availability was assessed by invertebrate sampling. Time, mean temperatures and the abundance of some prey taxa were inter-correlated and all contributed to influence the breeding phenology of both species according to partial least squares regression analysis. Besides some interspecific differences in the effect of environmental factors on the breeding phenology, we found strong similarities between the patterns observed in the two warblers. This suggests that, in spite of interspecific differences in life history, the ecological mechanisms shaping reproduction phenology are similar in the two warblers and the same environmental factors are involved in determining the timing of their reproduction.—Ceresa, F., Belda, E.J., Brambilla, M., Gómez, J., Mompó, C. & Monrós, J.S.

影响鸟类繁殖物候的因素:两种具有不同生活史的同域尖头莺的评价

总结。繁殖时间是一个重要的生活史特征，暗示着主要的适应性结果。生命史策略的差异可能导致对相同环境条件的不同反应，甚至在密切相关的物种之间也是如此。研究近缘同域物种繁殖时间的影响因素，有助于了解不同生活史性状与物种对生态因子的特异性反应之间的关系。本文研究了季节(光周期)、当地气候变化和猎物丰度对两种具有不同繁殖和换羽时间和不同迁徙策略的同域食虫鸟类——小胡子莺Acrocephalus melanopogon和欧亚芦苇莺Acrocephalus scirpaceus繁殖季节的影响。在五年期间，通过在标准化捕获期间检查鸟类孵化斑块来确定繁殖物候，并通过无脊椎动物抽样来评估食物供应。偏最小二乘回归分析表明，时间、平均温度和部分被捕食类群的丰度均对两个物种的繁殖物候有影响。除了环境因素对两种林莺繁殖物候的影响存在种间差异外，我们还发现两种林莺的繁殖物候模式具有很强的相似性。这表明，尽管两种林莺的生活史存在种间差异，但形成繁殖物候的生态机制是相似的，决定它们繁殖时间的环境因素是相同的。-Ceresa, F。,贝尔达、2陈焕祯Brambilla, M,戈麦斯,J。,Mompo, c &孟氏J.S.二(2020)。影响鸟类繁殖物候的因素:两种具有不同生活史的同域尖头莺的评估。中国生物医学工程学报，37(6):371-385。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
