Abstract
Pollen spectra from surface sediments of 29 lakes and ponds in Illinois, Missouri and Kentucky [USA] show high values of oak [Quercus] (mean 29%) and ragweed [Ambrosia] (mean 30%) and low percentages of conifer pollen. The data as a whole represent the oak-hickory [Carya] forest, although pollen spectra from smaller ponds show considerable variation. Revised isopoll maps are presented for oak, ragweed, hickory and elm [Ulmus].This publication has 0 references indexed in Scilit:
