This trend reflects a concomitant decrease in emphasis on marine resources and increased reliance on C<jats:sub>4<\/jats:sub>\u2010based resources, especially maize. This dietary reorientation is most apparent for the early agricultural sample (AD 1150\u20131300), coinciding with the Mississippian florescence in the eastern United States. There is, however, a shift toward the use of C<jats:sub>3<\/jats:sub> (non\u2010maize) foods during the last prehistoric period (AD 1300\u20131450), which is likely related to environmental stress and social disruption. A heavier use of maize and terrestrial resources in general after the establishment of mission centers on barrier islands is indicated. A reduced dietary breadth during the mission period may have contributed to the extinction of these populations in the eighteenth century. \u00a9 1992 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajpa.1330890206","type":"journal-article","created":{"date-parts":[[2006,2,3]],"date-time":"2006-02-03T19:54:41Z","timestamp":1138996481000},"page":"197-214","source":"Crossref","is-referenced-by-count":65,"title":["Carbon and nitrogen stable isotopic signatures of human dietary change in the Georgia Bight"],"prefix":"10.1002","volume":"89","author":[{"given":"Clark Spencer","family":"Larsen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret J.","family":"Schoeninger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolaas J.","family":"van der Merwe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine M.","family":"Moore","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia A.","family":"Lee\u2010Thorp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,4,27]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"78","volume-title":"Emergent Horticultural Economies of the Eastern Woodlands.
