Population changes in eastern hardwoods caused by air pollution
Berrang P, Karnosky D, Mickler R, Bennett J. 1986. Population changes in eastern hardwoods caused by air pollution
From the abstract: "Evolution of ozone tolerance can provide indirect evidence that air pollution is reducing growth of forest trees. Acer rubrum from natural populations in nine national parks and populus tremuloides from natural populations in five national parks were fumigated to determine ozone tolerances. Ozone tolerances of P. tremuloides populations from high and intermediate ozone areas were greater than ones from-low ozone areas. A. rubrum populations from areas with historically high ozone concentrations showed more tolerance than those from low or historically low ozone areas. These results suggest air pollution is reducing the reproductive fitness of some individuals in relatively polluted areas."
