Fig. 1From: Gut microbiota in two recently diverged passerine species: evaluating the effects of species identity, habitat use and geographic distanceRelative abundances of bacterial phyla (a) and genera (b) in common nightingale (CN) and thrush nightingale (TN) samples from allopatry and sympatry. The three gut sections (duodenum, DU; jejunum, JE; and ileum, IL) are shown separately. Only the most abundant phyla (relative abundance > 0.5%) and genera (relative abundance > 1%) are represented. Less abundant phyla and genera are included in the category ‘Others’Back to article page
