<b>Raw DNA sequences and genus-level dietary and vegetation matrices of sympatric herbivores along a grazing gradient</b>

<b>Data Overview:</b><br>This dataset supports the study "How much is too much? Grazing intensity governs wildlife–livestock interactions in alpine meadows." It contains raw environmental DNA (eDNA) sequencing data and processed genus-level abundance matrices used for dietary and niche overlap analyses.<b>1. Raw Sequencing Data (FASTQ)</b><b>Description:</b> Raw sequencing reads obtained from animal fecal samples targeting the chloroplast rbcL gene to identify dietary components.<b>File Format:</b> Compressed FASTQ (.fq.gz).<b>Naming Convention:</b> File names follow the format A_B_C.fq, where:<b>A</b>: Denotes the herbivore species (yak or pika).<b>B</b>: Denotes the Site ID (1–24), corresponding to the pasture numbering in Table S1 and S2 of the manuscript.<b>C</b>: Indicates the sequencing read direction (R1 for forward reads, R2 for reverse reads).<b>2. Processed Genus-level Matrices (CSV)</b><br>These files contain the processed taxonomic data used in the R code to generate Figure 4 and Figure 5.<b>diet_pika_genus.csv</b><b> </b><b>&amp;</b><b> </b><b>diet_yak_genus.csv</b>:<b>Content</b>: These files represent the dietary composition of pikas and yaks at the genus level.<b>Structure</b>: Rows represent the <b>Pasture ID</b> (1–24), and columns represent <b>Plant Genera</b>.<b>Values</b>: Cell values represent the <b>relative abundance (%)</b> of sequences assigned to each plant genus within the fecal sample.<b>plant_genus_matrix_100percent.csv</b>:<b>Content</b>: This file represents the plant community composition recorded during field vegetation surveys.<b>Structure</b>: Rows represent the <b>Pasture ID</b> (1–24), and columns represent <b>Plant Genera</b>.<b>Values</b>: Cell values represent the <b>relative Importance Value (IV)</b> of each genus in the field, normalized to sum to 100% per site.
