Natural Selection for Ozone Tolerance in Populus tremuloides
Berrang P, Karnosky D, Mickler R, Bennett J. 1986. Natural Selection for Ozone Tolerance in Populus tremuloides. Canadian Journal of Forest Research. 16:1214-1216
A study measuring relative ozone sensitivity, which suggests that some populations of P. tremuloides may have naturally selected for tolerance. FIELD WORK: Summer and Fall 1983. 11-14 individuals of Quaking Aspen were collected from 5 National Parks, including Acadia National Park, to investigate differences in ozone sensitivity among populations. Plants were grown in a greenhouse and fumigated with ozone. 'The average injury for clones was significantly less for the most polluted park than for the least polluted park and there was a high negative association between average injury and ambient ozone levels. These results suggest natural selection for tolerance in P. tremuloides may have occurred in some areas of eastern United States.' /STUDY LOCATIONS:/ /ACADIA NATIONAL PARK/
