From: Age-related variation in the oral microbiome of urban Cooper’s hawks (Accipiter cooperii)
Communities of bacteria in the oral cavity differed as a function of age class in Cooper’s hawks. Non-metric multi-dimensional scaling analyses of the 55 most common operational taxonomic units (OTU) reveal that communities of bacteria in the oral cavity differ between nestlings (open circles) and more mature age classes (fledglings, open squares; adults, filled circles), which in turn did not differ from each other. Results are consistent when evaluated using (a) presence-absence data (Jaccard’s Index) or (b) read number as a proxy for abundance (Simpson’s Index)
