A Bayesian model sensitivity study of non-static diet-collagen isotope fractionations factors used to assess breastfeeding and weaning practices among fisher-gatherers populations, western Cuba
Reconstructing paleo-diets from bone-collagen isotope values (carbon and nitrogen) requires proper knowledge of diet-collagen isotopic fractionations (∆d13Cdiet-col, ∆d15Ndiet-col). While these isotopic fractionations vary considerably among previous human paleo-diet reconstructions, some more recent studies have successfully employed "non-static" dietary offsets. New research suggests that non-static diet-collagen isotope fractionations is best when attempting to reconstruct paleo-diets of cultures consuming varied diets, particularly when used in association with a variety of new Bayesian multi-source stable isotope-mixing models now available. This particular study involves a sensitivity study of some non-static diet-collagen isotope fractionations employed in three Bayesian multi-source stable isotope-mixing models to assess breastfeeding and weaning practices among fisher-gatherer populations from Western Cuba.
