Based in extensive research in geology, atmospheric science, and paleontology, this book offers a detailed history of CO2 in the atmosphere, and an understanding of factors that have influenced changes in the past. The text illuminates the role of atmospheric CO2 in the modern carbon cycle and in the evolution of plants and animals, and addresses the future role of atmospheric CO2 and its likely effects on ecosystems.

The analysis of stable isotope ratios represents one of the most exciting new technical advances in environmental sciences. In this book, leading experts offer the first survey of applications of stable isotope analysis to ecological research. Central topics are - plant physiology studies - food webs and animal metabolism - biogeochemical fluxes. Extensive coverage is given to natural isotopes of carbon, hydrogen, oxygen, nitrogen, sulfur, and strontium in both terrestrial and marine ecosystems. Ecologists of diverse research interests, as well as agronomists, anthropologists, and geochemists...

This 33-chapter volume presents a critical examination of the importance of stable isotopes in understanding key plant metabolic processes.

• Carbon isotope analyses for estimates of plant water use and metabolism
• Integrated estimates of stress impacts and life history in ecological systems
• Hydrogen and oxygen isotope analyses for evaluating water sources and transpiration
• Use of stable isotopes in scaling from leaf to global levels
• Sections include: History and Theoretical Considerations, Ecological Aspects of Carbon Isotope Variation, Agricultural...
