Blue crab diet affects urine metabolite profile. PCA of metabolomics data from (A) ¹H NMR spectra and (B) MS differentiate urine of blue crabs fed mud crabs and from urine of blue crabs fed oysters along the first principal component (variance captured along PC1 is stated in parentheses; P = 0.0074 for NMR, P = 0.0003 for MS). Crab symbols represent data from urine from blue crabs fed mud crabs (n = 9 for NMR, n = 3 for MS); oyster symbols represent data from urine from blue crabs fed oysters (n = 10 for NMR, n = 3 for MS).
