Major bacterial taxa (> 1% in terms of read abundance) of the gastrointestinal (GI) microbiota samples collected from six breeding rookeries (Rasito, Partido, Machos, Granito, Coloradito, and Cantiles) in the Gulf of California (GoC). The DNA samples were pooled (see methods) and taxa were detected from each hypervariable region (V2 to V9) of 16S rRNA.
