Stable Isotope Analysis of Archaeological Faunal Remains From the Middle Trent Valley, Ontario

Description

A sample of faunal remains (n=129) from seven archaeological sites located on Pigeon and Rice Lakes, Ontario were sampled and analyzed for the stable carbon and nitrogen isotopic composition of bone collagen. These samples date from the Archaic to Late Woodland and include 35 different animal species. The goal of this research was to investigate the isotope ecology of the Middle Trent Valley and characterize the degree to which isotope ratios varied across space and time between different lakes, as wells as variation within and between species. There were no statistically significant differences in the Middle Trent Valley δ13C or δ15N according to space and time. As such, the isotope data for all archaeological sites were combined to construct an isotope food web for the Middle Trent Valley and compared to Katzenberg’s (1989) food web. These isotope data provide some insight into the dynamic interplay between local ecosystems, and anthropogenically modified landscapes in Ontario.
