Supplementary Figures from The relationship between dietary trophic level, parasites and the microbiome of Pacific Walrus ( Odobenus rosmarus divergens )
Arctic species are likely to experience rapid shifts in prey availability under climate change, which may alter their exposure to microbes and parasites. Here, we describe fecal bacterial and macroparasite communities and assess correlations with diet trophic level in Pacific walruses harvested duri...

Arctic species are likely to experience rapid shifts in prey availability under climate change, which may alter their exposure to microbes and parasites.
