Biogeochemistry of a Forested Ecosystem PDF Author: Gene E. Likens
Publisher: Springer Science & Business Media
ISBN: 1461242320
Category : Science
Languages : en
Pages : 171

Book Description
When we originally published Biogeochemistry of a Forested Ecosystem in 1977, the Hubbard Brook Ecosystem Study (HBES) had been in existence for 14 years, and we included data through 1974, or a biogeo chemical record of 11 years. Now our continuous, long-term biogeo chemical records cover more than 31 years, and there have been many changes. The most notable change, however, is that three of our coauthors on the original volume are now deceased. They are deeply missed in so many ways. In spite of the longer records, different trends, and new insights, we believe that the basic concepts and approaches we presented in 1977 represent the most valuable contribution of the original edition. They are still valid and useful, particularly for an introductory study of, or course in, biogeochemistry. Our goal in this revision is to preserve these fea tures, correct errors, and revise or eliminate misleading or ambiguous short-term data (11 years!), while maintaining approximately the original length and the modest cost.

Book Description
This book looks at the sources and composition of the atmosphere and rainfall, with particular attention on acidifying components and those that affect ecosystems. It further widens the subject to look at trace metals. It includes papers on the impact of deposition on soils and forests and the recovery of the natural environment. Work on critical loads makes a contribution to understanding the degree to which deposition must be reduced to limit its impact.

Nitrogen, the Confer-N-s

Nitrogen, the Confer-N-s PDF Author: K. van der Hoek
Publisher: Elsevier
ISBN: 0080984681
Category : Science
Languages : en
Pages : 813

Book Description
The First International Nitrogen Conference provided an opportunity for researchers and decision-makers to exchange information on environmental pollution by nitrogen compounds on three scales: global, continental/regional and local. The main topics were air, ground water and surface water pollution; emission sources, atmospheric chemistry, deposition processes and effects; disturbance of nitrogen cycles, critical loads and levels; assessments, policy development and evaluation; target groups and abatement techniques; and new approaches leading to an integrated abatement strategy.The peer-reviewed papers from the Conference presented in this volume will provide readers with a comprehensive review of the transport, deposition and impact on ecosystems of nitrogen.

The European Nitrogen Assessment

The European Nitrogen Assessment PDF Author: Mark A. Sutton
Publisher: Cambridge University Press
ISBN: 1139501372
Category : Science
Languages : en
Pages : 665

Book Description
Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.

Landscape Ecology of a Stressed Environment

Landscape Ecology of a Stressed Environment PDF Author: Claire C. Vos
Publisher: Springer Science & Business Media
ISBN: 9401123187
Category : Science
Languages : en
Pages : 391

Book Description
This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecol ogy addresses the relationships among spatial patterns, temporal pat terns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an import ant variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heteroge neous. Intellectual utility and applicability of results are valued equally. The International Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Preface In Europe, during the seventies, landscape ecology emerged as a fusion of the spatial approach of geographers and the functional approach of ecologists. The latter focused on ecosystem functioning, regarding eco systems as homogeneous, almost abstract units in space, with input and output of energy and matter to and from the undefined surroundings.

Atlas of Ecosystem Services

Atlas of Ecosystem Services PDF Author: Matthias Schröter
Publisher: Springer
ISBN: 3319962299
Category : Technology & Engineering
Languages : en
Pages : 406

Book Description
This book aims to identify, present and discuss key driving forces and pressures on ecosystem services. Ecosystem services are the contributions that ecosystems provide to human well-being. The scope of this atlas is on identifying solutions and lessons to be applied across science, policy and practice. The atlas will address different components of ecosystem services, assess risks and vulnerabilities, and outline governance and management opportunities. The atlas will therefore attract a wide audience, both from policy and practice and from different scientific disciplines. The emphasis will be on ecosystems in Europe, as the available data on service provision is best developed for this region and recognizes the strengths of the contributing authors. Ecosystems of regions outside Europe will be covered where possible.

Heathlands

Heathlands PDF Author: R. Aerts
Publisher: Springer Science & Business Media
ISBN: 9401582300
Category : Science
Languages : en
Pages : 228

Book Description
Increased atmospheric nitrogen deposition and changes in the management of heathlands have caused a significant change in the species composition of the NW-European heathlands. This change from ericaceous towards gramineous dominance is analysed in detail in Heathlands: Patterns and Processes in a Changing Environment. Special emphasis is put on the effects of increased atmospheric nutrient input on nutrient cycling, competition between plant species and plant--herbivore interactions. The possibilities for the long-term conservation of heathlands are discussed by considering regeneration from seed and the usefulness of mathematical management models. The book provides a synthesis of pure and applied plant ecology. It is vital reading for plant ecologists, biological conservationists, heathland managers and government decision makers.

Soil pollution: a hidden reality

Soil pollution: a hidden reality PDF Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9251305056
Category : Technology & Engineering
Languages : en
Pages : 156

Book Description
This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
