Coordinated transformation of the gut microbiome and lipidome of bowhead whales provides novel insights into digestion

摘要

Comparison of the bowhead whale microbiome and lipidome across the gastrointestinal (GI) tract of bowhead whales. Illustration of a bowhead whale feeding on zooplankton (inset: copepod and krill) and the nine GI areas from which samples of GI contents were collected. Nonmetric multidimensional scaling (nMDS) comparisons of Bray–Curtis dissimilarities of microbial communities based on the 361 minimum entropy decomposition nodes [ ] (MED nodes) (  = 121) and the 546 lipids (  = 106). For both figures, dispersion ellipse centroids are defined by the mean dissimilarities for each anatomical location and the ellipse shapes are defined by the covariances. Comparison of MDS1 scaling from the paired microbiome and lipidome samples across the GI tract (  = 105)
