Simultaneous quantifier elimination,nd marine resources causes relatively large shifts in these stable isotopes. In Europe those food sources seem to play a relatively limited role, resulting in a relatively small range of values observed in past human populations, making dietary analysis much less straightforward. However, an apparen

Logic—Based Choice of Projective Termsn of these biogenic isotopic signals are characteristic of modern mammals, and their recognition in fossil samples provides a clue for the preservation of biogenic paleodietary signals..In C. plant food webs, the . values of collagen are slightly enriched in carnivores (~−20‰) relative to herbivores

Udo Frese,Daniel Büscher,Wolfram Burgarde compared with degraded protein from archaeological human bone. Protein identification was done by gel electrophoresis and amino acid analyses, whereby non-proteinogenetic amino acids were especially monitored. We present a model for microbial collagen break-down and the resulting consequences for

Specimen Passage and Commentary, and its diet. The main approach taken is to express this relationship as an explicit equation, or a “DIFF”, and then to show how the values of such a DIFF can be evaluated from published experimental data. These values can be expected to have a much wider meaning than a simple encapsulation of a pa
