Available in PDF, EPUB and Kindle. Book excerpt: All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, Ecological Stoichiometry is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. From the foreword by Peter Vitousek: "[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . And if we are both lucky and good, this questioning and testing will advance our field beyond the level achieved in this book. I can't wait to get on with it."

Amino acid metabolism and nitrogen traffic during plant growth and development and details of protein biosynthesis in the seeds are also extensively covered. Finally, the effects of the application of nitrogen fertilisers on plant growth, crop yield and the environment are discussed. Written by international experts in their field, Plant Nitrogen is essential reading for all plant biochemists, biotechnologists, molecular biologists and physiologists as well as plant breeders, agricultural engineers, agronomists and phytochemists.

Download or read book Nitrogen Acquisition and Assimilation in Higher Plants written by Sara Amancio and published by Springer Science & Business Media. This book was released on 2007-09-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth. During the green revolution nitrogenfertilisation was responsible for spectacular yield increases. At present yield is balanced with commitments towards the environment and sustainable agriculture. For agro-biotechnology comprehensive knowledge of plant functioning is needed. Yield improvement and accumulation of essential nitrogen compounds is relying on selection and gene technologies. Research on the uptake, acquisition and assimilation of nitrogen, as well as the synthesis and storage of reserve and defence N-compounds, therefore, is essential. The third volume in the Plant Ecophysiology series integrates functional and molecular physiology with ecophysiological and sustainable agricultural approaches to get a better understanding of the regulation and the impact of environmental and stress signals on nitrogen acquisition and assimilation. The book is of interest for advanced students and junior researchers and supplies comprehensive information for scientists working in the field of nitrogen metabolism and readers interested in sustainable development.

Download or read book Root Demographics and Their Efficiencies in Sustainable Agriculture Grasslands and Forest Ecosystems written by James E. Box Jr. and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Society of Root Research sponsored the Symposium "Root Demographics and Their Efficiencies in Sustainable Agriculture, GrassLands and Forest Ecosystems," July 14-18, 1996, at the Madren Conference Center, Clemson University, Clemson, South Carolina, USA. The conference was a continuation of a series of international symposiums on root research held every three to four years. Symposiums have also been held twice in Vienna, Austria, and once in Uppsala, Sweden, and Almaty, Kazahkstan prior to the meeting at Clemson University. The sponsoring society has made a particular effort in these symposia to include root scientists from the former Soviet Union because of the importance of exchanging information on a worldwide basis. This symposium continued and promoted that effort by providing travel grants to several scientists from that region; however, funds for that purpose were limited. Therefore, in compiling these proceedings, a number of papers from scientists from the former Soviet Union and former Warsaw Pack countries have been included even though the scientists were not actually present for the SymPOSIum.

Download or read book Changes of Atmospheric Chemistry and Effects on Forest Ecosystems written by Reinhard F. Hüttl and published by Springer Science & Business Media. This book was released on 1998 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarises the result of an interdisciplinary research programme entitled `Rehabilitation of the Atmosphere of the New States of Germany - Effects on Terrestrial Ecosystems'. Before the unification of Germany, emission loads of SO2 and dust particles were up to 18-fold higher in East than in West Germany. However, emission rates have decreased significantly since reunification in 1990, due to the breakdown of a large number of industrial and particularly lignite- fired powerplants and the implementation of clean air technologies. In order to study the effects of these dramatic changes in atmospheric chemistry on terrestrial ecosystems, comprehensive field studies were conducted in pine forest ecosystems along an historic gradient of atmospheric deposition rates in the northeastern lowlands of Germany. The fast and dramatic reduction of dust particle and SO2 emissions offers a unique opportunity to test the role of SO2 and alkaline particle deposition with regard to changes or damage to forest ecosystems and whether the forest stands return to a state of resilience. In this respect, this ecosystem experiment can be looked upon as a roof experiment without a roof.

Download or read book Canopy Photosynthesis From Basics to Applications written by Kouki Hikosaka and published by Springer. This book was released on 2015-12-17 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last 30 years has seen the development of increasingly sophisticated models that quantify canopy carbon exchange. These models are now essential parts of larger models for prediction and simulation of crop production, climate change, and regional and global carbon dynamics. There is thus an urgent need for increasing expertise in developing, use and understanding of these models. This in turn calls for an advanced, yet easily accessible textbook that summarizes the “canopy science” and introduces the present and the future scientists to the theoretical background of the current canopy models. This book presents current knowledge of functioning of plant canopies, models and strategies employed to simulate canopy function, and the significance of canopy architecture, physiology and dynamics in ecosystems, landscape and biosphere.

Book excerpt: According to many textbooks, carbohydrates are the photosynthesis and mitochondrial respiration fluctuate in a circadian manner in almost every unique final products of plant photosynthesis. However, the photoautotrophic production of organic organism studied. In addition, external triggers and environmental influences necessitate precise and nitrogenous compounds may be just as old, in appropriate re-adjustment of relative flux rates, to evolutionary terms, as carbohydrate synthesis. In the algae and plants of today, the light-driven assimilation prevent excessive swings in energy/resource provision of nitrogen remains a key function, operating and use. This requires integrated control of the alongside and intermeshing with photosynthesis and expression and activity of numerous key enzymes in respiration.

Download or read book Capturing Carbon and Conserving Biodiversity written by Ian R Swingland and published by Routledge. This book was released on 2013-06-17 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades conservation has been based on the donor-driven principle. It hasn't worked. For centuries, environmental pollution or degradation has been addressed by the same attitude: the 'Polluter Pays' principle. That hasn't worked either. The cycle has to stop. But while everyone talks about using a market-driven approach, few know how to do it. Faced with the situation on the ground what do you do? What is happening? How can you engage a system so that it is self-sustaining and the people self-motivated? This study explores how the growing market in carbon can help to conserve carbon-based life forms. It discusses how reducing global warming and saving biodiversity can both be achieved with the right market conditions. The contributors include conservation biologists, ecologists, biologists, economists, lawyers, community and tribal specialists, financial specialists, market makers, environment specialists, climatologists, resource managers, atmospheric scientists, project developers and corporate fund managers.
