Ambient ozone effects on forest trees of the eastern United States: a review
Tropospheric ozone can affect crop yield and has been reported to cause reductions in growth and biomass of forest tree species in laboratory and glasshouse studies. However, linkages between growthExpand
The ozone component of global change: potential effects on agricultural and horticultural plant yield, product quality and interactions with invasive species.
It is concluded that current and projected levels of O3 in many regions worldwide are toxic to sensitive plants of agricultural and horticultural significance, while reductions in O3 precursor emissions will likely benefit world food production and reduce atmospheric concentrations of an important greenhouse gas.

Perspectives regarding 50 years of research on effects of tropospheric ozone air pollution on US forests.
Investigations on tree growth, O(3) flux, and stand productivity are being conducted along natural O( 3) gradients and in open-air exposure systems to better understand O(2) effects on forest ecosystems. Expand
Model estimates of net primary productivity, evapotranspiration, and water use efficiency in the terrestrial ecosystems of the southern United States during 1895–2007
Abstract The effects of global change on ecosystem productivity and water resources in the southern United States (SUS), a traditionally ‘water-rich’ region and the ‘timber basket’ of the country,Expand
Ambient Ozone and Plant Health.
Impacts of urbanization on carbon balance in terrestrial ecosystems of the Southern United States.
It is implied that it is important to take urbanization effect into account for assessing regional carbon balance, as the carbon sequestration rate of urban ecosystem diminishes with time, nearly disappearing in two centuries after land conversion. Expand
Stomatal behavior of ozone-sensitive and -insensitive coneflowers (Rudbeckia laciniata var. digitata) in Great Smoky Mountains National Park.
Stomata of sensitive plants were less responsive than those of insensitive plants to experimentally increased and decreased light intensities, and to increased VPD, while O(3)-insensitive plants had greater intrinsic transpirational efficiencies, greater maximum assimilation rates under saturating CO(2) and light, and greater carboxylation rates.

Comparison of carbon storage, carbon sequestration, and air pollution removal by protected and maintained urban forests in Alabama, USA
The Auburn University campus in Auburn, Alabama, USA, was the location for a case study to compare carbon storage, carbon sequestration, and air pollution (CO, O3, NO2, PM10, SO2) removal estimatesExpand
Seasonal profiles of leaf ascorbic acid content and redox state in ozone-sensitive wildflowers.
Different differences in antioxidant metabolism were found in the wildflower species that corresponded with differences in ozone sensitivity, and identified antioxidant compounds were present in the leaf apoplast of all three species. Expand
Century-Scale Responses of Ecosystem Carbon Storage and Flux to Multiple Environmental Changes in the Southern United States
Terrestrial ecosystems in the southern United States (SUS) have experienced a complex set of changes in climate, atmospheric CO2 concentration, tropospheric ozone (O3), nitrogen (N) deposition, andExpand
