“…Rodent feeding habits, digestive physiology, and metabolism differ in a number of ways from humans, and it is unclear if rodents are a good model organism for understanding isotopic incorporation in humans. By contrast, swine are thought to be a good model organism for studying human digestion and metabolism (Baker, 2008;Miller and Ullrey, 1987;Schook, 2007;Tumbleson, 1986). Our data, combined with those from other published swine studies, indicate that the correlation between collagen d 13 C and diet d 13 C is as good as, if not better than, the correlation between diet d 13 C and bone apatite d 13 C in large-bodied mammals fed naturalistic diets (Fig.…”

“…As large-bodied omnivores, pigs share many important physiological characteristics with humans and are considered a good model organism for the study of human digestion and metabolism (Tumbleson, 1986;Miller and Ullrey, 1987;Schook, 2007;Baker, 2008). This study additionally has important implications for archaeozoologists who are interested in understanding patterns of isotopic discrimination in managed or domesticated animal populations that may have experienced growth-related stress.…”

“…However, the protein contribution of maize to Canímar Abajo diet seems to have been low. It is possible that collagen stable isotope ratios underestimate the contribution of carbohydrate sources, such as maize, since collagen obtains most of its carbon from intact amino acids in dietary protein, with relatively less carbon coming from other macronutrients (Ambrose et al, 1997;Froehle et al, 2010;Schwarcz, 2000). While C 3 protein sources such as terrestrial mammals are 85e90% protein, maize is only 10% (Schober and Ambrose, 1995).…”

“…This is consistent with SIAR model results for Canímar Abajo, suggesting that marine resources were the most important animal protein source in the diet of both cemetery populations. Although collagen-derived carbon isotope values primarily reflect dietary protein sources, they can also provide the evidence of other macronutrients such as carbohydrates (e.g., plant contribution) (Froehle et al, 2010;Schwarcz, 2000). Therefore, the Canímar Abajo diet could have been similar to a mixed C 3 /C 4 diet of agricultural groups, which regularly consumed maize (Mickleburgh and Pag an Jim enez, 2012; Pag an Jim enez, 2007).…”
