Data from: Cultural traditions across a migratory network shape the genetic structure of southern right whales around Australia and New Zealand

Fidelity to migratory destinations is an important driver of connectivity in marine and avian species. Here we assess the role of maternally directed learning of migratory habitats, or migratory culture, on the population structure of the endangered Australian and New Zealand southern right whale. Using DNA profiles, comprising mitochondrial DNA (mtDNA) haplotypes (500 bp), microsatellite genotypes (17 loci) and sex from 128 individually-identified whales, we find significant differentiation among winter calving grounds based on both mtDNA haplotype (FST = 0.048, ΦST = 0.109, p Usage Notes Australian right whale microsatellite and stable isotope dataThis file contains the sampling location and state, mtDNA haplotype, sex, stable isotope and multi-locus microsatellite genotype data for Australian southern right whale samples used in the study.SREP16182_SRWdata_Archive.xlsxComparing_stable_isotope&genetic_similarity_filesDryad Archive for SREP16182: SI_SRW_data.zip. This zip file contains: 1 - Files of estimates of pairwise relatedness generated from microsatellite loci in SREP16182_SRWdata_Archive in the program COANCESTRY, using the kinship estimators of Lynch & Ritland 1999 (Lynch&Ritland_relatedness.txt) and Ritland 1996 (Ritland_relatedness.txt). 2 – Files of sample stable isotope values for both d13C (Sample_dC.txt) and d15N (Sample_dN.txt), as well as pairwise similarities of d13C calculated using Euclidean distance in program GENODIVE (dC_euclidean_correct_names.gdv). 3 – A file that includes d13C, d15N, mtDNA, sampling location and sex ID data for the samples used in the GLM work (SI_data_Aus_SRWtxt.txt) 4 – R code for (1) running the comparison of similarities between d13C and microsatellite-based kinship estimators and (2) running GLMs on d13C data, with mtDNA, sex and sampling state as potential explanatory factors. R code is annotated so it can be easily run if the files are placed in the appropriate files and required packages are downloaded.SI_SRW_data.zip迁徙目的地保真度是海洋与鸟类物种种群连通性的重要驱动因子。本研究针对濒危的澳新南露脊鲸（southern right whale），评估了母系定向的迁徙栖息地学习（即迁徙文化）对其种群结构的作用。我们依托128头经个体识别的鲸的DNA数据集——包含500bp长度的线粒体DNA（mitochondrial DNA, mtDNA）单倍型、17个位点的微卫星基因型及性别信息——分析发现，基于mtDNA单倍型的冬季产仔场之间存在显著遗传分化（FST = 0.048, ΦST = 0.109, p）。 【数据使用说明】澳大利亚露脊鲸微卫星与稳定同位素数据集 本文件包含本研究中使用的澳大利亚南露脊鲸样本的采样地点、采样州/省信息、mtDNA单倍型、性别、稳定同位素数据及多位点微卫星基因型数据，对应文件为SREP16182_SRWdata_Archive.xlsx。 SREP16182对应的Dryad存档文件为SI_SRW_data.zip，该压缩包包含以下内容： 1. 由微卫星位点计算得到的成对亲缘关系估计值文件：基于程序COANCESTRY中Lynch与Ritland 1999年亲缘估计法生成的Lynch&Ritland_relatedness.txt，以及Ritland 1996年亲缘估计法生成的Ritland_relatedness.txt。 2. 样本稳定同位素值文件：包括δ13C（Sample_dC.txt）与δ15N（Sample_dN.txt），以及在程序GENODIVE中通过欧氏距离计算得到的δ13C成对相似性文件dC_euclidean_correct_names.gdv。 3. 用于广义线性模型（Generalized Linear Model, GLM）分析的样本数据文件，包含δ13C、δ15N、mtDNA单倍型、采样地点及性别标识信息，即SI_data_Aus_SRWtxt.txt。 4. 用于以下分析的R代码：① 对比δ13C相似性与基于微卫星的亲缘关系估计值；② 以mtDNA单倍型、性别及采样州/省为潜在解释变量，对δ13C数据开展广义线性模型分析。代码已添加注释，若将相关文件置于对应路径并下载所需依赖包，即可直接运行。
