Ecophysiological responses of woody plants to past CO(2) concentrations.

An approach is detailed for calculating historical rates of CO(2) uptake and water loss of leaves from measurements of leaf delta(13)C composition and climatic information. This approach was applied to investigate leaf gas exchange metabolism of woody taxa during the past 200 years of atmospheric CO(2) increase and in response to the longer-term atmospheric CO(2) increases plants experienced ov...

Predicting Ecosystem Responses to Elevated CO2 Concentrations

O ne of the many changes occurring in the biosphere due . to human activities is the increase in the carbon dioxide concentration of the atmosphere. This change is due both to the burning of fossil fuels, which is ejecting approximately 5-6 gT of carbon into the atmosphere yearly, and to deforestation, which may account for another 1~2 gT (Moore and Bolin 1986/87, Detwiler and Hall 1988). The p...

Plant responses to low [CO2] of the past.

During the Last Glacial Maximum (LGM; 18,000-20,000 yr ago) and previous glacial periods, atmospheric [CO(2)] dropped to 180-190 ppm, which is among the lowest concentrations that occurred during the evolution of land plants. Modern atmospheric CO(2) concentrations ([CO(2)]) are more than twice those of the LGM and 45% higher than pre-industrial concentrations. Since CO(2) is the carbon source ...

Antioxidative Responses of Eucalyptus camaldulensis to Different Concentrations of Copper

Anthropogenic activities have caused important increases in soil Cu levels not only in urban areas but also in croplands. This study was designed to find out the effect of different concentration of copper on physiological and biochemical changes in Eucalyptus camaldulensis seedlings. Seeds of Eucalyptus camaldulensis were grown in marble chips and irrigated with nutrient solution mixed with co...

Boron deficiency in woody plants: various responses and tolerance mechanisms

Boron (B) is an essential microelement for higher plants, and its deficiency is widespread around the world and constrains the productivity of both agriculture and forestry. In the last two decades, numerous studies on model or herbaceous plants have contributed greatly to our understanding of the complex network of B-deficiency responses and mechanisms for tolerance. In woody plants, however, ...
