Book Synopsis Coastal-Offshore Ecosystem Interactions by : Bengt-Owe Jansson
Download or read book Coastal-Offshore Ecosystem Interactions written by Bengt-Owe Jansson and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges. In general, organic matter has isotope ratios characteristic of its origin (e. g. plants with different modes of photosynthesis and different growth conditions, anthropogenic compounds). These ratios are maintained as the organic matter moves through the biosphere and geosphere. A mixture of organic matter from two sources has isotope ratios intermediate between those of the two sources, in proportion to the fraction of material from each source. Isotope ratios are one of the few methods which can trace organic matter as it moves through natural ecosystems. Ratios can be measured on both the total organic matter and on particular chemical fractions or compounds. When used on organisms, isotope ratios provide information of organic matter actually assimilated into body tissues, not just material ingested. As with all tools, this method has certain limitations which must be borne in mind when interpreting its results. Firstly, specific environmental conditions must be met. This generally means an ecosystem with a limited and known number of sources of organic matter having different isotope ratios. Two sources with different isotope ratios are ideal; additional sources with other isotope ratios complicate interpretation. Secondly, the difference in isotope ratios of the two sources should be large compared with analytical variability. Thirdly, the ratios within each source should vary as little as possible.

Book Synopsis Growth and Defence in Plants by : R. Matyssek
Download or read book Growth and Defence in Plants written by R. Matyssek and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants use resources, i.e. carbon, nutrients, water and energy, either for growth or to defend themselves from biotic and abiotic stresses. This volume provides a timely understanding of resource allocation and its regulation in plants, linking the molecular with biochemical and physiological-level processes. Ecological scenarios covered include competitors, pathogens, herbivores, mycorrhizae, soil microorganisms, carbon dioxide/ozone regimes, nitrogen and light availabilities. The validity of the “Growth-Differentiation Balance Hypothesis” is examined and novel theoretical concepts and approaches to modelling plant resource allocation are discussed. The results presented can be applied in plant breeding and engineering, as well as in resource-efficient stand management in agriculture and forestry.

Book Synopsis Australian Saltmarsh Ecology by : Neil Saintilan
Download or read book Australian Saltmarsh Ecology written by Neil Saintilan and published by CSIRO PUBLISHING. This book was released on 2009 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian Saltmarsh Ecologypresents the first comprehensive review of the ecology and management of Australian saltmarshes. The past 10 years in particular have seen a sustained research effort into this previously poorly understood and neglected resource. In ten chapters contributed by experts in each discipline, the book outlines what is known of the biogeography and geomorphology of Australian saltmarshes, their fish and invertebrate ecology, the use of Australian saltmarshes by birds and insectivorous bats, and the particular challenges of management, including the control of mosquito pests and the issue of sea-level rise. It provides a powerful argument that coastal saltmarsh is a unique and critical habitat vulnerable to the combined impacts of coastal development and sea-level rise.
Book Synopsis Ecosystem Services and Global Trade of Natural Resources by : Thomas Koellner
Download or read book Ecosystem Services and Global Trade of Natural Resources written by Thomas Koellner and published by Taylor & Francis. This book was released on 2013-06-17 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The utilization of natural resources to satisfy worldwide growing consumption of goods and services has severe ecological consequences. Aside from the projected doubling of food consumption in the next fifty years, the growing trade of biofuels and other commodities is a global challenge as the economic activities in the primary sector (i.e. mining, fisheries, aquaculture, forestry and agriculture) can damage biodiversity and ecosystem services. This should be taken into account in the decision-making affecting the global value chains linking consumer, retailer, processor, and producer in the North and the South. To cover the topic of ecosystem services and global trade this book is organized into four major parts. Part 1 gives the theoretical framework from an ecological, economic and political perspectives. Part 2 explores how internationally traded biophysical commodities from agriculture, forestry and fisheries translates into a virtual flow of land, freshwater, and marine ecosystems. Part 3 describes how two widely used accounting tools (i.e., Life Cycle Assessment and Green National Accounts) deal with international aspects of ecosystem services, and Part 4 shows how instruments like labelling, bans, or payments for ecosystem services in the private and public sector can influence trade patterns and the management of ecosystem services. This collection is a valuable contribution to the global change science dealing with ecosystem services. It illustrates the consequences of international trade on global ecosystem services and provides an overview of accounting tools and of market-based policy instruments to address negative and positive externalities. The book is certainly innovative, because it brings together research findings from distinct disciplines especially Industrial Ecology and Ecosystem Sciences, as well as Environmental Economics and Political Science.

Available in PDF, EPUB and Kindle. Book excerpt: Ecology at the ecosystem level has both necessitated and benefited from new methods and technologies as well as those adapted from other disciplines. With the ascendancy of ecosystem science and management, the need has arisen for a comprehensive treatment of techniques used in this rapidly-growing field. Methods in Ecosystem Science answers that need by synthesizing the advantages, disadvantages and tradeoffs associated with the most commonly used techniques in both aquatic and terrestrial research. The book is divided into sections addressing carbon and energy dynamics, nutrient and water dynamics, manipulative ecosystem experiements and tools to synthesize our understanding of ecosystems. Detailed information about various methods will help researchers choose the most appropriate methods for their particular studies. Prominent scientists discuss how tools from a variety of disciplines can be used in ecosystem science at different scales.
Book Synopsis The Fungal Community by : John Dighton
Download or read book The Fungal Community written by John Dighton and published by CRC Press. This book was released on 2005-05-24 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fungal Community: Its Organization and Role in the Ecosystem, Third Edition addresses many of the questions related to the observations, characterizations, and functional attributes of fungal assemblages and their interaction with the environment and other organisms. This edition promotes awareness of the functional methods of classification over taxonomic methods, and approaches the concept of fungal communities from an ecological perspective, rather than from a fungicentric view. It has expanded to examine issues of global and local biodiversity, the problems associated with exotic species, and the debate concerning diversity and function. The third edition also focuses on current ecological discussions - diversity and function, scaling issues, disturbance, and invasive species - from a fungal perspective. In order to address these concepts, the book examines the appropriate techniques to identify fungi, calculate their abundance, determine their associations among themselves and other organisms, and measure their individual and community function. This book explains attempts to scale these measures from the microscopic cell level through local, landscape, and ecosystem levels. The totality of the ideas, methods, and results presented by the contributing authors points to the future direction of mycology.

Book excerpt: This partially annotated bibliography contains the first 1000 references from a computerized file of literature on the global ecological implications of carbon cycles and climatic changes. Many early citations originated from the Biogeochemical Ecological Information Center established at Oak Ridge National Laboratory in 1968 and from profiles of computerized files such as Government Research Abstracts (GRA) and Biological Abstracts (BA). Later citations have been extracted from the open literature through 1978 and early 1979, from government reports and impact statements, and from profiles of GRA, BA, and the Energy Data Base of the Department of Energy Technical Information Center, Oak Ridge, Tennessee. The subject categories covered by this bibliography may be divided into two main topics: carbon cycling and climate system analysis. Volume I contains an introduction and overview. Volume 2 contains an alphabetical (by author) listing of citations. Volume 3 provides indexes for author, organization (corporate authority), keywords (or free index terms), taxonomic category, subject category, Chemical Abstracts codes, Biological Abstracts codes (crosscode), and COSATI/Weekly Government Abstracts codes concentrated with permuted title words.
