Book Description
Exposure to elevated levels of atmospheric CO2 for a period of 17 years resulted in small but statistically significant decreases in wood basic specific gravity and number of rays per millimeter. Other anatomical characteristics (percentages of tissues, number of vessels per square millimeter, vessel diameters, and fiber wall thickness) were unaffected by treatment. Differences due to distance from pith were important, but cardinal direction (north, south, east, west) was not.

Book Description
The carbon dioxide (CO2) concentration of Earth's atmosphere continues to rise. Plants in general are responsive to changing CO2 concentrations, which suggests changes in agricultural productivity in the United States and around the world. The ability of plants to absorb CO2 during photosynthesis and then store carbon in their structure or sequester it in the soil has potential for mitigating the rate of rise of atmospheric CO2 concentration. Since 1987, Bruce Kimball and coworkers at the USDA Agricultural Research Service in Phoenix, Arizona, have maintained a greenhouse gas experiment using sour orange trees maintained in a CO2- enriched environment. These trees were harvested in 2005. During the final massive harvest, many different properties and characteristics of the woody biomass for these sour orange trees were studied. This report focuses only on the mechanical property evaluation of modulus of elasticity (MOE), specific gravity, and microfibril angle. In this study of CO2-exposed sour orange trees, CO2 did not significantly affect specific gravity of sour orange trees. Exposure to CO2 did not significantly affect MOE of sour orange trees. Exposure to CO2 did, however, seem to influence microfibril angle development. Minor interactions between CO2 and cardinal direction affected the MOE and were caused by experimental difference in chamber construction.

Book Description
The last decade has seen rapid and major advances in our understanding of the physiological ecology of plants. This volume reviews some of these advances and new challenges. The chapters cover five broad themes: resource acquisition and utilization; interactions between organisms; responses to global environmental changes; ecosystems; and integration and scaling. This book brings together an unrivalled collection of leading practitioners in the discipline from North America, Europe and Australia and adopts a broad approach, ranging from the molecular to the ecosystem level. It has proven a valuable tool for researchers and advanced students in the discipline.
