Isotopic trends in the diets of hunter-gatherers of the lower Paraná wetland, South America

The results of the isotopic analysis of 23 individuals recovered in the lower Paraná wetland, South America, are presented. The samples were recovered from complex hunter-gatherer sites ranging from the years 1800 to 600 BP. Two isotopic trends were identified. The first one is based on depleted pro...
