Body site microbiota of Magellanic and king penguins inhabiting the Strait of Magellan follow species-specific patterns
Animal hosts live in continuous interaction with bacterial partners, yet we still lack a clear understanding of the ecological drivers of animal-associated bacteria, particularly in seabirds. Here, we investigated the effect of body site in the structure and diversity of bacterial communities of two...
