Table 4 OTUs shared between birds and their burrow mates. Significance was determined using Welch’s two sample t test. Birds did not share more OTUs with their burrow mates than with a randomly selected non-mate (p > 0.05)

From: Morphological and genetic factors shape the microbiome of a seabird species (Oceanodroma leucorhoa) more than environmental and social factors
