Redundancy analysis triplot showing the relationship between the top 15 prokaryotic genus-level phylogenetic groupings of the OTUs for which the variation is best explained by the constrained axes. Arrow length indicates the variance that can be explained by equine type, with the perpendicular distance of the equine types to the arrow indicating the relative abundance of the genus-level phylogenetic grouping. Arrow labels indicate the taxonomic affiliation of genus-level phylogenetic groups, with the level (i.e. phylum (p), class (c), order (o), family (f) or genus (g)) and taxon (as defined by the Silva 16S rRNA database) that the groups could be reliably assigned to. For example “g__Pseudobutyrivibrio” represents an OTU reliably assigned to the genus Pseudobutyrivibrio, whereas “o_Mollicutes_RF9;f,g__NA” was reliably assigned to the order Mollicutes_RF9 but the family and genus could not be annotated (NA). *Due to space constraints, one of the arrow labels was shortened on the plot and the full label is as follows: p_Planctomycetes;c__Pla4_lineage;o__uncultured_rumen_bacterium;f,g__NA. Equine type means (large symbols) and individual samples (small symbols) are coded by equine type: donkey (red circle), pony (green square) and pony × donkey (blue triangle). Equine type explained 22.8% of the total variation in the dataset, and the plot axes are labelled with the amount of variation they represent
