Despite an increasing appreciation of the importance of host-microbe interactions in ecological and evolutionary processes, the factors shaping microbial communities in wild populations remain poorly understood. We therefore exploited a natural experiment provided by two adjacent Antarctic fur seal (Arctocephalus gazella) colonies of high and low social density and combined 16S rRNA metabarcoding with microsatellite profiling of mother-offspring pairs to investigate environmental and genetic influences on skin microbial communities. Seal-associated bacterial communities differed profoundly between the two colonies, despite the host populations themselves being genetically undifferentiated. Consistent with the hypothesis that social stress depresses bacterial diversity, we found that microbial alpha diversity was significantly lower in the high-density colony. Seals from one of the colonies that contained a stream also carried a subset of freshwater-associated bacteria, indicative of an influence of the ... : AFSmicrobiome_SI_OTUprocessingPipelineScripts_DatasetS1Collection of scripts for the OTU processing pipelineAFSmicrobiome_SI_OTUprocessingPipelineStatistics_DatasetS2Summary statistics for the OTU processing pipelineAFSmicrobiome_SI_Rmarkdown_DatasetS3_htmlR Markdown file in .html format containing all the R code used for the analyses of the Antarctic fur seal microbiomeAFSmicrobiome_SI_Rmarkdown_DatasetS3_Final_revision.htmlAFSmicrobiome_SI_Rmarkdown_DatasetS3_RmdR Markdown file in Rmd format containing all the R code used for the analyses of the Antarctic fur seal microbiomeAFSmicrobiome_SI_Rmarkdown_DatasetS3_Final_revision.RmdAFSmicrobiome_SI_SequencingStatsFile_Rinput_DatasetS4R markdown input file containing sequencing statisticsAFSmicrobiome_SI_MicrosatelliteGenotypes50_P22removed_colnames_Rinput_DatasetS5R markdown input file containing genotypes at 50 microsatellite loci for 95 fur seal individuals (pup P22 was removed due to large number of missing genotypes).
