Dryad 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.
