Data for: Estimating heritability of song considering within-individual variance in a wild songbird: the collared flycatcher

Data for: Heritability of song in the collared flycatcher The table "songheritability_data.csv" contains all data used in the animal models investigating variance components five song traits: song length, mean frequency, frequency bandwidth, tempo and complexity. The other variables are date and year of the measurements, age and identity of the birds, order of the songs in the recording, recording ID and song ID. Continuous variables were z-transformed. The table "geneticsimilaritymatrix.csv" contains the genetic similarity matrix of the individuals with song data, used in the animal models. The R script file "songheritability_code.R" contains R code necessary for reproducing the results reported in the manuscript. Song recording was collected from collared flycatchers (Ficedula albicollis) from 2008-18. We catched these birds and collected blood samples from them and recorded their age (one-year old or older). Five song traits, which were extracted from the song recordings with the help of Ficedula toolbox, were used in the analyses: song length, mean frequency, frequency bandwidth, tempo and complexity. All continuous variables included into the models were z-transformed. Genetic similarity matrix was calculated based on more than 50 000 single nucleotide polymorphism.

数据集说明：领斑姬鹟鸣声的遗传力

名为`songheritability_data.csv`的数据表包含了用于探究5项鸣声性状方差组分的动物模型所需的全部数据，这5项鸣声性状分别为鸣声时长、平均频率、频率带宽、鸣唱速率以及鸣唱复杂度。其余变量包括测量日期与年份、鸟类的年龄与个体标识、录音内鸣声的序列编号、录音ID以及鸣声ID。所有连续变量均经Z变换标准化处理。

名为`geneticsimilaritymatrix.csv`的数据表包含了带有鸣声数据的个体的遗传相似性矩阵，该矩阵用于前述动物模型分析。

`songheritability_code.R`脚本文件包含了复现论文中报告结果所需的R代码。

本次研究的鸣声录音采集自2008年至2018年间的领斑姬鹟（*Ficedula albicollis*）。研究人员捕获这些鸟类并采集血液样本，同时记录其年龄（1龄或更年长个体）。

本次分析共使用5项从鸣声录音中提取得到的鸣声性状，提取过程借助Ficedula工具箱完成，这5项性状分别为鸣声时长、平均频率、频率带宽、鸣唱速率以及鸣唱复杂度。纳入统计模型的所有连续变量均经Z变换标准化处理。遗传相似性矩阵基于超过50000个单核苷酸多态性（single nucleotide polymorphism, SNP）位点计算得到。
