FIGURE 2.
NIR of sequential hair segments collected at 2 locations: community A visit 1 (A) and visit 2 (B) and community B visit 2 (C). Only participants with ranges in sequential hair NIR ≥1.4‰ are shown. Community B visit 1 is omitted because no participants had ranges ≥1.4‰. The “summer” months (Apr–Oct) are marked with a gray vertical bar. NIR, nitrogen isotope ratio, expressed as δ15N values.
