Download or read book Hemispherical Photography in Forest Science Theory Methods Applications written by Richard A. Fournier and published by Springer. This book was released on 2017-05-11 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents practical information about hemispherical photography from the perspectives of field data acquisition, image processing and information retrieval methods. This book is organized into three sections. The first section describes what is hemispherical photography and what are the fundamental elements of forest structure and light interactions within the forest canopy. The second section provides practical information about the equipment, procedures and tools for procuring, processing and analyzing hemispherical photographs. Armed with this information, the third section describes several applications of hemispherical photographs to forestry and natural resource assessment. The book concludes with a discussion about modelling tools and future directions of this rapidly growing field. There is currently no information source on the market that has this comprehensive range of topics combined in a single book. The book will appeal to academics, graduate students, natural resource professionals and researchers alike.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The solar radiant energy is in fact the only source of energy for the basic physical processes taking place in the atmosphere and on the earth's surface. When passing through the atmosphere and being reflected by the ground surface, solar radiation undergoes changes and conversions. Some of it is absorbed in the atmosphere and converted into other forms of energy, mainly into heat, and some is scattered by gases, by dust and by water vapour. Because of absorption and scattering in the atmosphere, solar radiation is changed by the time it reaches the earth's surface. That part of it which arrives as a beam of parallel rays is referred to as direct solar radiation, and that which is scattered in the atmosphere and reaches the earth's surface from all directions of the sky is called diffuse solar radiation. Both of them are reflected back into the atmosphere when they reach the earth's surface, and this third type of radiation is defined as reflected radiation. All of these radiations differ from solar radiation arriving at the upper level of the atmosphere in intensity as well as in spectral composition although they all fall within the spectral region of solar radiation. In atmospheric physics these types of radiation are known as short-wave radiation (SWR) as distinguished from long-wave or irifrared radiation (L WR) emitted by the atmosphere and the earth's surface.
Download or read book Stereo Photo Guide for Estimating Canopy Fuel Characteristics in Conifer Stands written by Joe H. Scott and published by . This book was released on 2005 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stereo photographs, hemispherical photographs, and stand data are presented with associated biomass and canopy fuel characteristics for five Interior West conifer stands. Canopy bulk density, canopy base height, canopy biomass by component, available canopy fuel load, and vertical distribution of canopy fuel are presented for each plot at several stages of sampling, each corresponding to a level of simulated low thinning (100, 75, 50, and 25 percent of the initial basal area). This guide will help fuel managers estimate canopy fuel characteristics in similar forest conditions.
Download or read book Photon Vegetation Interactions written by Ranga B. Myneni and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photon-Vegetation Interactions deals with the interaction of electromagnetic radiation with vegetation canopies. The approach to the various aspects is mainly theoretical and consequently the subject is being treated as a special branch of mathematical physics. A major emphasis is on the development of theoretical methods for determining the reflection function of vegetation canopies in optical remote sensing. Furthermore, the coupling of the radiative transfer theory with leaf photosynthesis to evaluate the productivity of vegetation canopies is treated as well as the theory of photon transport in phototropic and other biological media.

Download or read book Plant Physiological Ecology written by R. Pearcey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological plant ecology is primarily concerned with the function and performance of plants in their environment. Within this broad focus, attempts are made on one hand to understand the underlying physiological, biochemical and molecular attributes of plants with respect to performance under the constraints imposed by the environment. On the other hand physiological ecology is also concerned with a more synthetic view which attempts to under stand the distribution and success of plants measured in terms of the factors that promote long-term survival and reproduction in the environment. These concerns are not mutually exclusive but rather represent a continuum of research approaches. Osmond et al. (1980) have elegantly pointed this out in a space-time scale showing that the concerns of physiological ecology range from biochemical and organelle-scale events with time constants of a second or minutes to succession and evolutionary-scale events involving communities and ecosystems and thousands, if not millions, of years. The focus of physiological ecology is typically at the single leaf or root system level extending up to the whole plant. The time scale is on the order of minutes to a year. The activities of individual physiological ecologists extend in one direction or the other, but few if any are directly concerned with the whole space-time scale. In their work, however, they must be cognizant both of the underlying mechanisms as well as the consequences to ecological and evolutionary processes.
Download or read book Perspectives in Biophysical Plant Ecophysiology written by Erick De La Barrera and published by UNAM. This book was released on 2009 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Park S. Nobel pioneered the coupling of cellular physical chemistry with plant physiology, providing a sound physicochemical interpretation of the laws of diffusion to a rapidly expanding field of plant physiological ecology. His classical textbook is the only one of its kind to provide an extensive array of quantitative problems and solutions in the field of plant biophysics and ecophysiology, extending from the molecular to the ecological level. In this festschrift, former graduate students and postdocs, as well as colleagues of Prof. Nobel present a series of reviews that include scales from sub-cellular to global, and topics that range from desert succulent biology to the physiology of alpine plants, encompassing basic research and applications in agronomy and conservation biology. This state-of-the-field survey provides current and useful information for professionals and graduate students, while illustrating the broad span of the influence that Nobel's career has had on modern ecophysiology.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Control of Plant Growth consists of the proceedings of a symposium held at Canberra, Australia, in August 1962. The symposium aims to consider the natural microenvironments of plants and the associations between natural and controlled environments. It also considers the physiological and genetic bases of responses by plants to environmental conditions. The book contains 24 chapters and discusses the physics of plant environment, as well as the physical quantities within plant-air layers. It also elucidates the energy and water balance, light relations, gas exchange, and energy relations in plant communities. The book also looks into the respiration of various organs and of whole plants. Lastly, the effects of the environment, including "climatic factors, on the metabolism of plant cells are addressed.
