Boreal Shield Watersheds: Lake Trout Ecosystems in a Changing Environment brings together the work of a renowned international group of scientists who specialize in aquatic science and environmental management. They explore the functioning of Boreal Shield ecosystems, focusing on the lake trout, the classic coldwater species of northern glaciated lakes, using it as an indicator of environmental change and as a model to measure the effectiveness of management actions. This book demonstrates how boreal waters have served as a crucible for decades of environmental research into the impacts of nutrient additions, trace contaminants, acid rain, climate change, sport fishing, invasive species, and watershed disturbances. The text builds on this substantial research legacy and explores our ability to manage human interactions with ecosystems across the vast Boreal Shield ecozone of North America, and with other important ecosystems worldwide. It also provides models and new methods of assessing the risk to and the durability of ecosystems in relation to local, regional, and global human activities. Maps and descriptions of several important long-term monitoring sites and an atlas describing more than 3,000 lake trout lakes in the region are special components of the book.

The scientific community has voiced two general concerns about the future of the earth. Firstly, climatologists and oceanographers have focused on the changes in our physical environment, ie climate, oceans, and air. And secondly, environmental biologists have addressed issues of conservation and the extinction of species. There is increasing evidence that these two broad concerns are intertwined and mutually dependent. Past changes in biodiversity have both responded to and caused changes in the earths environment. In its discussions of ten key terrestrial biomes and freshwater ecosystems, this volume uses our broad understanding of global environmental change to present the first comprehensive scenarios of biodiversity for the twenty-first century. Combining physical earth science with conservation biology, the book provides a starting-point for regional assessments on all scales. The book will be of interest to those concerned with guiding research on the changing environment of the earth and with planning future policy, especially in accordance with the Global Biodiversity Convention.

Understanding how photosynthesis responds to the environment is crucial for improving plant production and maintaining biodiversity in the context of global change. Covering all aspects of photosynthesis, from basic concepts to methodologies, from the organelle to whole ecosystem levels, this is an integrated guide to photosynthesis in an environmentally dynamic context. Focusing on the ecophysiology of photosynthesis – how photosynthesis varies in time and space, responds and adapts to environmental conditions and differs among species within an evolutionary context – the book features contributions from leaders in the field. The approach is interdisciplinary and the topics covered have applications for ecology, environmental sciences, agronomy, forestry and meteorology. It also addresses applied fields such as climate change, biomass and biofuel production and genetic engineering, making a valuable contribution to our understanding of the impacts of climate change on the primary productivity of the globe and on ecosystem stability.

Cold adaptation is a much neglected field in the minds of climate change researchers and policy makers. However, increasing fluctuations in temperature means that the risk of cold stress will pose an increasing threat to both wild and cultivated plants and animals, with frost injury expected to cause devastating damage to crops on an increasingly large scale. Conversely, species already adapted to cold seasonality are declining in numbers and threatening both wildlife and human food sources. Thus, improving shared knowledge of the biological mechanisms of cold adaptation in plants and animals will help prevent major losses of crops and genetic resources in the future. This book is the first to focus on the mechanistic similarities between species in their responses to cold in a multi-organism approach that addresses the challenges and impacts of climate change on cold adaptation in micro-organisms (including pathogens), invertebrates, economically and scientifically important plants and vertebrates in both terrestrial and marine environments. The book concludes with a focus on the interactions between organisms, exploring common mechanisms in cold adaptation and dormancy.

This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.

Filling a long-standing need for a desk reference that synthesizes current research, Land Use Effects on Streamflow and Water Quality in the Northeastern United States reviews and discusses the impact of forest management, agriculture, and urbanization. The book provides a gateway to the diverse scientific literature that is urgently needed to understand and solve ubiquitous watershed management problems. The authors use an in-depth approach that focuses on the science behind sound management principles and practices. The book begins with a summary of the scientific principles and processes that define and govern the interactions between activities on land and conditions in streams, lakes, and estuaries. Building on these principles, later chapters progress from basic science to small-scale, controlled field experiments to landscape-scale studies and their watershed management implications. This nested format parallels the development of watershed management projects and solutions. The deliberate integration of land use history, ecology, hydrology, chemistry, and resource management avoids the artificial separation of inter-related watershed characteristics and tracks causes and effects over realistic time scales. The authors present the hydrologic and water quality principles on which to construct management plans for water supply watersheds across a wide range of sizes, configurations, and time scales. Rigorously reviewed by a distinguished panel of scientists and watershed managers, the book benefits from their collective experience across the full range of watershed science and management. It provides a diverse audience with the opportunity to update and expand their knowledge in critical areas of watershed science and management.

Coastal East and Southeast Asia are characterized by wet growing seasons, and species-rich forest ecosystems develop throughout the latitudinal and altitudinal gradients. In this region, the Global Change Impacts on Terrestrial Ecosystems in Monsoon Asia (TEMA) project was carried out as a unique contribution to the international project Global Change and Terrestrial Ecosystems. TEMA aimed to integrate forest ecosystem processes, from leaf physiology to meteorological budget and prediction of long-term change of vegetation composition and architecture through demographic processes. Special attention was given to watershed processes, where forest ecosystem metabolism affects the properties and biogeochemical budgets of freshwater ecosystems, and where rivers, wetlands, and lakes are subject to direct and indirect effects of environmental change. This volume presents the scaling-up concept for better understanding of ecosystem functioning.
