Abstract: | Palynological analyses of sediment cores from Patton Bog in southeastern Ohio recorded environmental changes from ca. 1000 B.C. to the present, representing the first pollen core analyzed from this region. Pollen data show an increase in prairie species, implying periodic expansion of grassland environments during the Woodland period coeval with the initial collection and eventual domestication of Eastern Agricultural Complex seeds. It is suggested that these environmental changes influenced human decisions concerning plant domestication and diet in the mid-Ohio Valley. |
