Age Differences and Population Variation in Stable Isotope Values from Ontario, Canada

摘要: The use of stable isotopes has become well established as a method for reconstructing prehistoric human diet. In most studies, the objective been one comparing groups either in space or time, example, inland versus coastal dwellers (Tauber 1981; Chisholm et al. 1982; Schoeninger 1983; Hobson and Collier 1984; Sealy van der Merwe 1985, 1986; Walker DeNiro 1986) agricultural preagricultural peoples within region (van Vogel 1978; Boutton Schwarcz 1985; see 1991 Katzenberg 1992 recent reviews). These questions have traditionally addressed using bones from small number adults. first studies to examine all individuals skeletal sample, Lovell (1986) presented evidence lack age sex differences carbon isotope ratios northern Plains population. However other suggested that this may not be true (Bumsted 1993). Of particular note is study by Fogel (1989) Tuross (in press) which provides related nitrogen due breastfeeding weaning.
