Book Description
The BOREAS TE-6 team collected several data sets to examine the influence of vegetation, climate, and their interactions on the major carbon fluxes for boreal forest species. This data set contains summaries of predawn leaf water potentials and foliage moisture contents collected at the TF and CEV sites that had canopy access towers. The data were collected on a nearly weekly basis from early June to late August 1994 by TE-06, members of the BOREAS staff, and employees of Environment Canada. The data are provided in tabular ASCII files. The data files are available on a CD-ROM (see document number 20010000884), or from the Oak Ridge National Laboratory (ORNL) Distributed Activity Archive Center (DAAC). Hall, Forrest G.

Book Description
This is a thorough study of photosynthetic mechanisms from cells to leaves, crown, and canopy. The authors question whether photosynthetic adaptations take place primarily at the metabolic and biochemical level or through changes in structure and form, or both. The text goes on to analyze the relative importance of genes that control metabolic and light reactions, and the structure, arrangement, and orientation of photosynthesis.
Australian Plant Communities

Category : Nature
Languages : en
Pages : 510
Book Description
For 100 million years the Gondwanan vegetation of Australia has survived and developed in the face of vast changes in climate and soils. The pressure imposed on the vegetation by European settlers during the last 200 years is in clear contrast to the minimal impact of Aborigines. Environmental managers and planners predicting the short- and long-term effects of environmental changes on ecosystems need to understand the basic principles of plant community physiology. Australian Plant Communities: The Dynamics of Structure, Growth and Biodiversity is the first synthesis of the physiological processes that shape Australian vegetation at the level of the entire plant community. It examines the basic principles of community physiology by referring to the vegetation of Australia, with its great diversity of natural plant communities, many of which are still relatively undisturbed. The principles developed are applicable to landscapes throughout the world. By revealing the fundamental determinants of vegetation structure, the book enables the effects of climate change on biodiversity, of both vegetation and its associated fauna, to be predicted. Plant Communities in Australia, lavishly illustrated with figures and graphs, is written in a clear and concise style and refers to many studies of the processes operating in Australian vegetation. It is an excellent text for undergraduate and graduate courses in environmental science, resource management, and environmental planning and impact assessment. It is also an invaluable reference for practising environmental scientists, planners, and managers.
Cellular Aspects of Wood Formation
Author: Jörg FrommPublisher: Springer Science & Business Media
ISBN: 3642364918
Category : Nature
Languages : en
Pages : 265
Book Description
With today’s ever growing economic and ecological problems, wood as a raw material takes on increasing significance as the most important renewable source of energy and as industrial feedstock for numerous products. Its chemical and anatomical structure and the excellent properties that result allow wood to be processed into the most diverse products; from logs to furniture and veneers, and from wood chippings to wooden composites and paper. The aim of this book is to review advances in research on the cellular aspects of cambial growth and wood formation in trees over recent decades. The book is divided into two major parts. The first part covers the basic process of wood biosynthesis, focusing on five major steps that are involved in this process: cell division, cell expansion, secondary cell wall formation, programmed cell death and heartwood formation. The second part of the book deals with the regulation of wood formation by endogenous and exogenous factors. On the endogenous level the emphasis is placed on two aspects: control of wood formation by phytohormones and by molecular mechanisms. Apart from endogenous factors, various exogenous effects (such as climate factors) are involved in wood formation. Due to modern microscopic as well as molecular techniques, the understanding of wood formation has progressed significantly over the last decade. Emphasizing the cellular aspects, this book first gives an overview of the basic process of wood formation, before it focuses on factors involved in the regulation of this process.

Agrometeorology

Pages : 384
Book Description
Learn how the climate can affect crop production! Agrometeorology: Principles and Applications of Climate Studies in Agriculture is a much-needed reference resource on the practice of merging the science of meteorology with the service of agriculture. Written in a concise, straightforward style, the book presents examples of clinical applications (methods, techniques, models, and services) in varying climates and agricultural systems, documenting up-to-date research literature from around the world. Its systematic approach—different from most books on the subject—makes it an essential tool for teaching, planning, and practical use by working farmers, as it examines topics such as solar radiation, effective rain, drought monitoring, evapotranspiration, and remote sensing. Agrometeorology: Principles and Applications of Climate Studies in Agriculture examines the developing discipline that international agencies such as the World Meteorological Organization (WMO) and the Food and Agriculture Organization (FAO) have declared to be an important growth area in university education. A panel of academics, researchers, and practitioners explore the role of agrometeorology in optimum crop growth, from the interactions between meteorological and hydrological factors and agriculture, including horticulture, animal husbandry, and forestry. The book addresses pressing topics of agriculture resource utilization and management, such as regional and land use planning; soil and water conservation; frost; growing degree day; risk analysis of climate hazards; animal parasites; harvest forecasts; crop models; decision support systems (DSS); agroclimatological forecast; and the ecological and economic implications of climate change. Agrometeorology: Principles and Applications of Climate Studies in Agriculture also addresses: managing farm water resources environmental temperature planning for frost mitigation photosynthetically active radiation (PAR) thermoperiodism managing the extremes—droughts and floods using computers to manage agricultural systems and much more! The interdisciplinary focus and reader-friendly style of Agrometeorology: Principles and Applications of Climate Studies in Agriculture make the book invaluable to scientists, planners, and academics working in the major agricultural sciences, geography, natural resource studies, and meteorology.
