Providing the researcher with the methodology appropriate to field experiments and useful analytical techniques this book includes measurements both of the environment itself and of the physiological and morphological responses of plants to it. In some cases, for example stable isotope measurements, investigations are performed in the laboratory on samples collected under field conditions, while other chapters cover analytical techniques for use in the field. Many techniques reviewed are based on the central theme of the acquisition of resources such as carbon, light, water and nutrients, and the use of these resources for plant growth. Methods for estimating some of the costs of allocation of these resources to particular functions are also covered. A methodological framework is provided for extending from organ level measurements to whole plants on root system and canopy structure, and to ecosystem level processes.

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 will value this overview for its wealth of information on theoretical background, experimental approaches, and technical design of studies utilizing stable isotope ratios.
