Table 4. Diet-to-tissue offset and weight contribution of the different food fractions towards a dietary proxy signal.
Dietary proxy | Offset | Weight contribution | ||
Bulk | Protein | Energy | ||
13Ccoll | 4.8(0.5) | 0(−) | 74(4) | 26(−) |
15Ncoll | 3.6(1.2) | 0(−) | 100(−) | 0(−) |
13Cglu | 9.2(1.8) | 100(−) | 0(−) | 0(−) |
Values in parentheses represent uncertainty. When a dash sign is used this indicates that the uncertainty was considered negligible.
