e noted some misprints in our paper. These misprints do not affect the arguments, the results and the overall conclusions of the paper. The analytical precision for carbon (%C) and nitrogen (%N) content should be 0.9% and 0.2% instead of the values of 0.009% and 0.002%, for %C and %N, respectively. The corresponding values in the paper that should be corrected are found on page 8299 and in Table S5 in Supporting Information; a table with corrected values is provided below. Table S5.

The analytical accuracy was calculated as the difference between average test results and the true result of a series of measurements with known result. Analytical precision was calculated as the standard deviation of a series of measurements. Values are expressed in ‰ for δ13C and δ15N; and in % for %C and %N.
