Experimental reduction of male wing length reveals benefits of pairing with good fathers

This study examined natural variation in male wing length, paired with an experimental reduction in this trait, in a wild population of Prothonotary Warblers (Protonotaria citrea). The data collected for this study at the University of Memphis' Edward J. Meeman Biological Station (35.3637N, 90.0177W) are contained in a .SAS file that is intended to be immediately executable to recreate all analyses reported in the associated paper. Provided in this file are a total of 7 datasets with raw and standardized values (for continuous variables): (i) Unique_males2017, (ii) Nests2017, (iii) Expt_nests, (iv) Expt_nests_stacked, (v) Expt_young), (vi) All_nests2017_2024, (vii) All_recruits. All analyses were conducted using SAS (ver. 9.4).本研究针对原食虫莺（Protonotaria citrea）的野生种群，探究了雄性翅长的自然变异，并针对该性状开展了实验性缩减处理。本研究的数据采集于孟菲斯大学爱德华·J·米曼生物站（35.3637°N，90.0177°W），所有采集数据存储于一个SAS格式文件中，该文件可直接运行以复现关联论文中报告的全部分析流程。该文件中共包含7组数据集，涵盖连续变量的原始值与标准化值：(i) Unique_males2017、(ii) Nests2017、(iii) Expt_nests、(iv) Expt_nests_stacked、(v) Expt_young、(vi) All_nests2017_2024、(vii) All_recruits。所有分析均通过SAS（版本9.4）完成。
