title: Data from: Interspecific variation in gut microbiome diversity across the Etosha National Park herbivore community

description: Data (both phyloseq-R object from imported QIIME2 artifacts, and demultiplexed EMP-paired end sequences from Argonne National laboratory) and R code

Raw sequencing reads from Argonne National Laboratory: - Undetermined_S0_L001_I1_001.fastq (barcodes)- Undetermined_S0_L001_R1_001.fastq (forward)- Undetermined_S0_L001_R2_001.fastq (reverse)

HerbivoreMeta2.tsv – Metadata file with each row representing individual samples and columns representing sample ID (SampleID), host species (sample_Species), sex (Sex), geographic zone each sample was collected from in Etosha National Park (Zone), feeding strategy of host species (FeedStrat), gut morphology of host species (GutMorph), waterhole site sample was collected from (Waterhole), and host taxonomic family (Family)

Herbivorerooted-tree-filtered.qza – QIIME2 artifact created after filtering sequences and creating rooted tree for phylogenetic diversity analyses

Herbivoretable-clean-unassigned-Unk-Euk.qza – QIIME2 artifact created by filtering out mitochondria, chloroplasts, unassigned taxa, Bacteria-only assigned taxa, and Eukaryota-only assigned taxa from Argonne National Lab sequences
