The 20th century has experienced environmental changes that appear to be unprecedented in their rate and magnitude during the Earth's history. For the first time, Stable Isotopes as Indicators of Ecological Change brings together a wide range of perspectives and data that speak directly to the issues of ecological change using stable isotope tracers. The information presented originates from a range of biological and geochemical sources and from research fields within biological, climatological and physical disciplines covering time-scales from days to centuries. Unlike any other reference, editors discuss where isotope data can detect, record, trace and help to interpret environmental change. - Provides researchers with groundbreaking data on how to predict the terrestrial ecosystems response to the ongoing rapid alterations - Reveals how ecosystems have responded to environmental and biotic fluctuations in the past - Includes examples from research by a wide range of biological and physical scientists who are using isotopic records to both detect and interpret environmental change
(Parent with price) Volume I contains subjective reviews, specialized and novel technique descriptions by guest authors. Part 1 includes contributions on purely analytical techniques and Part 2 includes matters such as development of mass spectrometers, stability of ion sources, standards and calibration, correction procedures and experimental methods to obtain isotopic fractionation factors.Volume II will be available in 2005.

Plants require a proper balance of matter and energy to maintain their survival and reproduction. Biotic and/or abiotic stresses in diverse environments could influence plant photosynthesis, water and nutrient acquisition and utilization. Through the lens of plant physiological and functional ecology, the study of responses of individual plant traits and/or integration of plant responses to environmental change has been well developed. The variation of plant physiological characteristics and functional traits has been recognized with hundreds of high-quality papers on topics of plant responses to environmental stresses. For now, despite the increasing number of studies trying to establish a linkage between plant physiological processes and functional traits, these covariations have received limited theoretical and experimental verification. This knowledge gap hampers our ability to understand and predict the comprehensive responses of plants to environmental stresses at different scales.
This volume contains a selection of scientific papers which were presented at an international workshop on the impacts of climatic variability held in Wengen, Switzerland, September 1997. For the first time, an assessment is made of the interactions between physical and biological elements of the Earth System on the basis of shifts in extreme climatic conditions, rather than simply changes in mean atmospheric conditions which research has tended to focus on until recently. Natural ecosystems and forests are typical examples of systems which, while constrained within certain ranges of mean climate, can undergo rapid and often irreversible damage in the face of short-lived but intense extreme events.
This Open Access volume highlights how tree ring stable isotopes have been used to address a range of environmental issues from paleoclimatology to forest management, and anthropogenic impacts on forest growth. It will further evaluate weaknesses and strengths of isotope applications in tree rings. In contrast to older tree ring studies, which predominantly applied a pure statistical approach this book will focus on physiological mechanisms that influence isotopic signals and reflect environmental impacts. Focusing on connections between physiological responses and drivers of isotope variation will also clarify why environmental impacts are not linearly reflected in isotope ratios and tree ring widths. This volume will be of interest to any researcher and educator who uses tree rings (and other organic matter proxies) to reconstruct paleoclimate as well as to understand contemporary functional processes and anthropogenic influences on native ecosystems. The use of stable isotopes in biogeochemical studies has expanded greatly in recent years, making this volume a valuable resource to a growing and vibrant community of researchers.
