Fig. 4From: Multi-level comparisons of cloacal, skin, feather and nest-associated microbiota suggest considerable influence of horizontal acquisition on the microbiota assembly of sympatric woodlarks and skylarksBeta diversity of bacterial communities associated with different sample types of sympatric lark species. Principal coordinate analysis (PCoA) of weighted UniFrac distances among sample types is shown along the first two principal coordinate axes and was calculated on a single rarefied data set and visualised for both species separately. Clustering significance was determined by PerMANOVA. Sample type (33%, P < 0.001) and lark species (1%, P < 0.05) explained total variationBack to article page
