Ecology, Planning, and Management of Urban Forests : International Perspective
Ecology, Planning, and Management of Urban Forests contains studies and perspectives on urban forests from a broad array of basic and applied scientific disciplines including ecosystem ecology, biogeochemistry, landscape ecology, plant community ecology, geography, and social science. The book contains contributions from experts in Asia, Europe, and North America, allowing the reader to evaluate methods and management that are appropriate for particular geographic, environmental, and socio-political contexts. Urban forests are also approached on regional and landscape scales to encompass more natural environments in and around cities, rather than within arbitrary municipal boundaries. The studies provided are intended to motivate scientists, planners, and managers to work together and to adopt a broader landscape ecology approach to urban forestry, and in so doing, better address the pressing needs for improving the quality of life in urban environments.
Ecology of Tidal Freshwater Swamps of the Southeastern United States
This book draws together the latest findings from investigators focusing on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.
Ecology of Riparian Forests in Japan : Disturbance, Life History, and Regeneration
It presents the dynamics and mechanisms that govern the coexistence of riparian tree species, tree demography, the response to water stress of trees, and the conservation of endangered species, and focuses on natural disturbances, life-history strategies, and the ecophysiology of trees. Because many riparian landscapes have been degraded and are disappearing at an alarming rate, the regeneration of the remaining riparian ecosystems is urgent. With contributions by more than 20 experts in diverse fields, this book offers useful information for the conservation, restoration, and rehabilitation of riparian ecosystems that remain in world streams and rivers.
Ecology and Conservation of Neotropical Montane Oak Forests
Covers the range of natural and managed oak forests in the highlands of tropical America. Providing an understanding of ecological patterns and processes that determine the structure and functioning of these forests, this volume aims to serve as a basis for sustainable forest management and biodiversity conservation.
Combinatorial Stochastic Processes : Ecole d'Eté de Probabilités de Saint-Flour XXXII - 2002
This volume contains the course “Combinatorial stochastic processes” of Professor Pitman. We cordially thank the author for his performance in Saint-Flour and for these notesThere is particular focus on the theory of random combinatorial structures such as partitions, permutations, trees, forests, and mappings, and connections between the asymptotic theory of enumeration of such structures and the theory of stochastic processes like Brownian motion and Poisson processes.
Martens and Fishers (Martes) in human-altered environments : An international perspective
Examines the conditions where humans and martens are compatible and incompatible, and promotes land use practices that allow Martes to be representatively distributed and viable. All Martes have been documented to use forested habitats and 6 species (excluding the stone marten) are generally considered to require complex mid- to late-successional forests throughout much of their geographic ranges. All species in the genus require complex horizontal and vertical structure to provide escape cover protection from predators, habitat for their prey, access to food resources, and protection from the elements. Martens and the fisher have high metabolic rates, have large spatial requirements, have high surface area to volume ratios for animals that often inhabit high latitudes, and often require among the largest home range areas per unit body weight of any group of mammals. Resulting from these unique life history characteristics, this genus is particularly sensitive to human influences on their habitats, including habitat loss, stand-scale simplification of forest structure via some forms of logging, and landscape-scale effects of habitat fragmentation. Given their strong associations with structural complexity in forests, martens and the fisher are often considered as useful barometers of forest health and have been used as ecological indicators, flagship, and umbrella species in different parts of the world. Thus, efforts to successfully conserve and manage martens and fishers are associated with the ecological fates of other forest dependent species and can greatly influence ecosystem integrity within forests that are increasingly shared among wildlife and humans.We have made great strides in our fundamental understanding of how animals with these unique life history traits perceive and utilize habitats, respond to habitat change, and how their populations function and perform under different forms of human management and mismanagement.
Managing Forest Ecosystems : The Challenge of Climate Change
With climate change now charging up the political agenda, there are three issues commonly making the headlines: carbon budgets, renewable energy, and the anticipated impacts of climate change. Equally important, though currently less well covered, is the issue how these effects might be mitigated. Given the significant role that forests play in the climate system – as sources, sinks, and through carbon trading – this book discusses the current scientific evidence on the relationships between climate, forest resources and forest management practices around the world. Drawing on expertise from forest scientists from several continents, the book presents both in depth analysis of the current knowledge, and a series of case studies which assess the biological and the economic impacts of climate change. It includes sections on forest responses to climate change, monitoring and modeling changes, economic and management implications, and carbon sequestration under specific management systems.
Managed Ecosystems and CO2 : Case Studies, Processes, and Perspectives
Managed ecosystems cover a large part of the Earth's land surface, provide almost all of our food and most of our wood and fibre, and are increasingly a source of renewable energy. Forecasting the ability of managed ecosystems to continue these vital roles in a globally changing environment is an inter-disciplinary challenge. To elucidate the complex responses of managed systems to elevated [CO2], several free air carbon dioxide enrichment (FACE) facilities were established. These FACE systems allow large areas to be exposed to the elevated [CO2] we expect by the middle of the century. This volume summarizes the main findings from 13 experiments with annual crops, permanent pastures and plantation forests at 11 sites throughout the world during the past ten years. The results significantly alter our perception of how rising [CO2] will directly affect these managed ecosystems, with implications for policy, plant-breeding objectives and adaptation.
Long-Term Ecosystem Changes in Riparian Forests
Presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time.
Lamto : Structure, Functioning, and Dynamics of a Savanna Ecosystem
Known as "a dream place for scientists," the Lamto savannas, located on the edge of the Cote d'Ivoire rain forests, are one of the only savannas in the world where ongoing ecological research has endured for more than forty years. Drawing from and synthesizing this abundance of research, the book examines the structure, functioning, and dynamics of the Lamto humid savanna. Beginning with the history of the Lamto ecology station and an overview of the major environmental conditions of the site, this exacting work specifically examines the integrative view of energy and nutrient fluxes relative to the dynamics of the savanna's vegetation.
Changing Forests : Collective Action, Common Property, and Coffee in Honduras
It merges political ecology, collective-action theories, and institutional analysis to study how the people and forests have changed through socioeconomic and political transitions. It studies the complex, often contradictory relationships between the people and their natural resources to understand why forest cover endures."Changing Forests" therefore encompasses three broad phases: (1) the premodern period, which considers historic perturbations in western Honduras from the period of colonialism into the middle of the twentieth century; (2) the period of state-led logging and intervention in La Campa, which caused major degradation in forest cover; and (3) the recent period in which export coffee production transformed property rights, and people’s perceptions of the forest gained new conservationist and economic dimensions. Each phase entails perspectives and experiences that influenced human use of forests, and shaped subsequent transformations.
Boreal Forest and Climate Change
There are several crucial feedbacks from forests to the climate system. The mechanisms for those feedbacks are elaborated in the book: they involve changes in the carbon cycle, albedo, N2O emissions and the production of aerosols. Much of this work is new and the feedback relationships have not yet been incorporated into models of the climate system. The book will be an important introduction for students and climate modellers alike, providing conceptual tools and ideas that are broadly applicable to terrestrial systems.
Bioproducts From Canadas Forests : New Partnerships in the Bioeconomy

It also offers a balanced discussion of the technological, policy and regulatory issues surrounding the emerging global bioeconomy. This book will not only be of interest to Canadian forestry professionals and entrepreneurs, but also to those interested in the contribution of forestry to the bioeconomy worldwide.
Biodiversity and Ecophysiology of Yeasts
In the last few decades more and more yeast habitats that were not investigated earlier, spanning cold climates to tropical regions and dry deserts to rainforests, have been explored. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. The recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.
Agricultural Implications of the Fukushima Nuclear Accident (III)
Reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants.
Acid Rain - Deposition to Recovery
Acid rain is still with us. Although it is a problem that people have worked diligently to solve, there are still many problem areas throughout the world. In reality the focus of acid rain research has shifted, and this book adds new vision to the topic. It contains papers, selected from Acid Rain 2005, the 7th International Conference on Acid Deposition, that take a broad perspective of the issues, emphasizing a number of themes: - the emission, concentration and deposition of pollutants / - nitrogen and trace elements in ecosystems and their effects on forests, water and soil / - studies of material damage and recovery - critical loads / The book is aimed at scientists and researchers who are working in the area of acid rain and its effects, and on nutrient cycling. This latest research will be of value to those concerned with the mitigation of acid rain effects.
