Figure 1From: Uropygial gland size and composition varies according to experimentally modified microbiome in Great titsExperimental modification of bacterial densities in nests and on feathers. Full circles represent the total cultivable bacterial densities, empty circles the keratinolytic bacterial densities (a: nests; b: plumage; mean ± SE of log transformed CFU). Bacterial densities on adults from the two sexes were not differently affected by the treatments (treatment * sex interactions, all P > 0.05).Back to article page
