| tree physiology book: Applications of Physiological Ecology to Forest Management J. J. Landsberg, S. T. Gower, 1997 Forest management is a complex process that now incorporates information obtained from many sources. It is increasingly obvious that the physiological status of the trees in a forest has a dramatic impact on the likely success of any particular management strategy. Indeed, models described in this book that deal with forest productivity and sustainability require physiological information. This information can only be obtained from an understanding of the basic biological mechanisms and processes that contribute to individual tree growth. This valuable book illustrates that physiological ecology is a fundamental element of proficient forest management. Provides essential information relevant to the continuing debate over sustainable forest management Outlines how modern tools for physiological ecology can be used in planning and managing forest ecosystems Reviews the most commonly used forest models and assesses their value and future |

| tree physiology book: Tree Rings and Climate H Fritts, 2012-12-02 Tree Rings and Climate deals with the principles of dendrochronology, with emphasis on tree-ring studies involving climate-related problems. This book looks at the spatial and temporal variations in tree-ring growth and how they can be used to reconstruct past climate. Factors and conditions that appear most relevant to tree-ring research are highlighted. Comprised of nine chapters, this book opens with an overview of the basic biological facts and principles of tree growth, as well as the most important terms, principles, and concepts of dendrochronology. The discussion then shifts to the basic biology governing the response of ring width to variation in climate; systematic variations in the width and cell structure of annual tree rings; and the significance of tree growth and structure to dendroclimatology. The movement of materials and internal water relations of trees are also considered, along with photosynthesis, respiration, and the climatic and environmental system. Models of the growth-climate relationships as well as the basic statistics and methods of analysis of these relationships are described. The final chapter includes a general discussion of dendroclimatographic data and presents examples of statistical models that are useful for reconstructing spatial variations in climate. This monograph will be of interest to climatologists, college students, and practitioners in fields such as botany, archaeology, hydrology, oceanography, biology, physiology, forestry, and geophysics. |

| tree physiology book: Native Trees of Western Washington Kevin W. Zobrist, 2021-06-22 Soft layers of moss and pine needles carpet the ground as dappled sunlight or misty rain filters through the forest canopy’s branches. Western Washington woodlands can be enchanting. Fortunately these magical places are abundant, covering half the state’s soil. Affording beauty and recreation as well as economic value, they endure as one of the area’s most important natural assets. In Native Trees of Western Washington, Washington State University’s Kevin Zobrist examines regional indigenous trees from a forestry specialist’s unique perspective. He explains basic tree physiology and a key part of their ecology--forest stand dynamics. He groups distinctive varieties into sections, describing common lowland conifers and broadleaved trees, high-elevation species found in the Olympic Mountains and western side of the Cascades, and finally, those with a very limited natural range and small, isolated populations. Numerous full-color photographs illustrate key traits. In addition, Zobrist discusses notable features, offering information about where to find particular species. He includes brief lists of some common human uses, citing Native American medicines, food, and materials, as well as commercial utilization from the time of European settlement to the present day. The result is a delightful and enlightening exploration of western Washington timberlands. |

| tree physiology book: Plant Physiological Ecology Hans Lambers, F. Stuart Chapin III, Thijs L. Pons, 2013-04-17 The individual is engaged in a struggle for existence (Darwin). That struggle may be of two kinds:The acquisition of the resources needed for establishment and growth from a sometimes hostile and meager environment and the struggle with competingneighbors of the same or different species. In some ways, we can define physiology and ecology in terms of these two kinds of struggles. Plant ecology, or plant sociology, is centered on the relationships and interactions of species within communities and the way in which populations of a species are adapted to a characteristic range of environments. Plant physiology is mostly concerned with the individual and its struggle with its environment. At the outset of this book, the authors give their definition of ecophysiology, arriving at the conclusion that it is a point of view about physiology. A point of view that is informed, perhaps, by knowledge of the real world outside the laboratory win dow. A world in which, shall we say, the light intensity is much greater than the 2s 1 200 to 500llmoi photons m- - used in too many environment chambers, and one in which a constant 20°C day and night is a great rarity. The standard conditions used in the laboratory are usually regarded as treatments. Of course, there is nothing wrong with this in principle; one always needs a baseline when making comparisons. The idea, however, that the laboratory control is the norm is false and can lead to misunderstanding and poor predictions of behavior. |

| tree physiology book: Like a Tree Jean Shinoda Bolen, 2011-04-01 A Powerful and Poetic Call to Ecological & Feminist Activism This masterful work by internationally known author and speaker Jean Shinoda Bolen provides an insightful look into the fusion of ecological issues and global gender politics. Of trees and women. This book on the importance of trees grew out of Bolen’s experience mourning the loss of a Monterey pine that was cut down in her neighborhood. That, combined with her practice of walking among tall trees, led to her deep connection with trees and an understanding of their many complexities. From their anatomy and physiology, to trees as archetypal and sacred symbols, Bolen expertly explores the dynamics of ecological activism spiritual activism and sacred feminism. And, she invites us to join the movement to save trees. Stories of those making a difference. While there is still much work to be done to address environmental problems, there are many stories of individuals and organizations rising up to make a change and help save our planet. The words and stories that Bolen weaves throughout this book are both inspirational and down-to-earth, calling us to realize what is happening to not only our trees, but our people. By writing about both the work of organizations like Greenpeace and the UN Commission on the Status of Women, Bolen highlights her passions and shares her unique vision for the world. In Like a Tree learn more about: The dynamic nature of trees — from their anatomy to their role as an archetypal symbol Pressing social issues such as deforestation, global warming, and overpopulation What it means to be a “tree person” If you enjoyed books like The Hidden Life of Trees, Wise Trees, Around the World in 80 Trees, or Braiding Sweetgrass, then you’ll love Like a Tree: How Trees, Women, and Tree People Can Save the Planet. |

| tree physiology book: Plant Allometry Karl J. Niklas, 1994-10-17 Allometry, the study of the growth rate of an organism's parts in relation to the whole, has produced exciting results in research on animals. Now distinguished plant biologist Karl J. Niklas has written the first book to apply allometry to studies of the evolution, morphology, physiology, and reproduction of plants. Niklas covers a broad spectrum of plant life, from unicellular algae to towering trees, including fossil as well as extant taxa. He examines the relation between organic size and variations in plant form, metabolism, reproduction, and evolution, and draws on the zoological literature to develop allometric techniques for the peculiar problems of plant height, the relation between body mass and body length, and size-correlated variations in rates of growth. For readers unfamiliar with the basics of allometry, an appendix explains basic statistical methods. For botanists interested in an original, quantitative approach to plant evolution and function, and for zoologists who want to learn more about the value of allometric techniques for studying evolution, Plant Allometry makes a major contribution to the study of plant life. |
