Book Synopsis Ecosystem Management in the Boreal Forest by : Sylvie Gauthier
Download or read book Ecosystem Management in the Boreal Forest written by Sylvie Gauthier and published by PUQ. This book was released on 2009 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.

Book Synopsis A Critique of Silviculture by : Klaus J. Puettmann
Download or read book A Critique of Silviculture written by Klaus J. Puettmann and published by Island Press. This book was released on 2012-09-26 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discipline of silviculture is at a crossroads. Silviculturists are under increasing pressure to develop practices that sustain the full function and dynamics of forested ecosystems and maintain ecosystem diversity and resilience while still providing needed wood products. A Critique of Silviculture offers a penetrating look at the current state of the field and provides suggestions for its future development. The book includes an overview of the historical developments of silvicultural techniques and describes how these developments are best understood in their contemporary philosophical, social, and ecological contexts. It also explains how the traditional strengths of silviculture are becoming limitations as society demands a varied set of benefits from forests and as we learn more about the importance of diversity on ecosystem functions and processes. The authors go on to explain how other fields, specifically ecology and complexity science, have developed in attempts to understand the diversity of nature and the variability and heterogeneity of ecosystems. The authors suggest that ideas and approaches from these fields could offer a road map to a new philosophical and practical approach that endorses managing forests as complex adaptive systems. A Critique of Silviculture bridges a gap between silviculture and ecology that has long hindered the adoption of new ideas. It breaks the mold of disciplinary thinking by directly linking new ideas and findings in ecology and complexity science to the field of silviculture. This is a critically important book that is essential reading for anyone involved with forest ecology, forestry, silviculture, or the management of forested ecosystems.
Book Synopsis Wood Quality and its Biological Basis by : John Barnett
Download or read book Wood Quality and its Biological Basis written by John Barnett and published by John Wiley & Sons. This book was released on 2009-02-18 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the most versatile raw material available to man. It isburned as fuel, shaped into utensils, used as a structuralengineering material, converted into fibres for paper production,and put to newer uses as a source of industrial chemicals. Its quality results largely from the chemical and physicalstructure of the cell walls of its component fibres, which can bemodified in nature as the tree responds to physical environmentalstresses. Internal stresses can accumulate, which are releasedcatastrophically when the tree is felled, often rendering thetimber useless. The quality of timber as an engineering materialalso depends on the structure of the wood and the way in which ithas developed in the living tree. Tree improvement for quality cannot be carried out without anunderstanding of the biological basis underlying wood formation andstructure. This volume brings together the viewpoints of bothbiologists and physical scientists, covering the spectrum from theformation of wood to its structure and properties, and relatingthese properties to industrial use. This is a volume for researchers and professionals in plantphysiology, molecular biology and biochemistry.
Download or read book Plant Physics written by Karl J. Niklas and published by University of Chicago Press. This book was released on 2012-02-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Galileo, who used the hollow stalks of grass to demonstrate the idea that peripherally located construction materials provide most of the resistance to bending forces, to Leonardo da Vinci, whose illustrations of the parachute are alleged to be based on his study of the dandelion’s pappus and the maple tree’s samara, many of our greatest physicists, mathematicians, and engineers have learned much from studying plants. A symbiotic relationship between botany and the fields of physics, mathematics, engineering, and chemistry continues today, as is revealed in Plant Physics. The result of a long-term collaboration between plant evolutionary biologist Karl J. Niklas and physicist Hanns-Christof Spatz, Plant Physics presents a detailed account of the principles of classical physics, evolutionary theory, and plant biology in order to explain the complex interrelationships among plant form, function, environment, and evolutionary history. Covering a wide range of topics—from the development and evolution of the basic plant body and the ecology of aquatic unicellular plants to mathematical treatments of light attenuation through tree canopies and the movement of water through plants’ roots, stems, and leaves—Plant Physics is destined to inspire students and professionals alike to traverse disciplinary membranes.
Book Synopsis Old-Growth Forests by : Christian Wirth
Download or read book Old-Growth Forests written by Christian Wirth and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many terms often used to describe old-growth forests imply that these forests are less vigorous, less productive and less stable than younger forests. But research in the last two decades has yielded results that challenge the view of old-growth forests being in decline. Given the importance of forests in battling climate change and the fact that old-growth forests are shrinking at a rate of 0.5% per year, these new results have come not a moment too soon. This book is the first ever to focus on the ecosystem functioning of old-growth forests. It is an exhaustive compendium of information that contains original work conducted by the authors. In addition, it is truly global in scope as it studies boreal forests in Canada, temperate old-growth forests in Europe and the Americas, and global tropical forests. Written in part to affect future policy, this eminently readable book is as useful for the scientist and student as it is for the politician and politically-interested layman.

Book excerpt: "This is a very readable book in which the ecological concepts are carefully explained and the glossary of key terms will be a welcome inclusion for those getting to grips with ecology. The book will therefore appeal to a wide readership of aquatic ecologists and foresters, both professional and amateur alike". Scottish Forestry Royal Scottish Forestry Society"...the book makes a very significant contribution to our growing awareness of the ecological importance of driftwood. This contribution is founded on two particular aspects of the book: the writing style, which is clear and directed very much at the general reader; and the scope of the book, which is very broad and, to my knowledge, goes far beyond other reviews of the topic". Angela Gurnell School of Geography, University of Birmingham British Journal of Forestry"This is not a review article containing a current review of all works on wood in aquatic ecosystems. Instead, it is a comprehensive treatment of the general role of wood". J.L. Tank and J.R. Webster Journal of the North American Benthological SocietyFrom the Forest to the Sea: The Ecology of Wood in Streams, Rivers, Estuaries and Oceans is a fascinating scientific work that discusses the role wood plays in very complex and diverse aquatic ecosystems. Until now almost nothing has been published on this little understood topic.-- European settlement and laissez-faire capitalism-- Streams-- The Sea-- The Sea and estuaries-- Rivers

Book Synopsis Qualité du bois et de la fibre d'épinette noire après coupe partielle by : Braido Dos Santos Diego Valerio
Download or read book Qualité du bois et de la fibre d'épinette noire après coupe partielle written by Braido Dos Santos Diego Valerio and published by Editions Universitaires Europeennes. This book was released on 2015-08-10 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les coupes partielles sont une alternative a la coupe totale en etant appliquees dans le but d'assurer l'approvisionnement en fibres et de maintenir la biodiversite ainsi que d'ameliorer la croissance radiale des arbres. Neanmoins, peu d'etudes ont evalue l'evolution de la qualite du bois avec le temps apres le traitement. L'impact des 3 intensites des coupes partielles a ete evalue sur la longueur et la largeur des tracheides ainsi que sur la largeur et la masse volumique du bois de l'epinette noire. Les variations intra-arbres de ces proprietes avant les coupes partielles furent aussi etudiees. Les mesures ont ete faites a differentes hauteurs dans l'arbre, sur 5 annees et sur 4 classes de DHP. La variation radiale de toutes les proprietes etudiees a ete plus prononcee que la longitudinale et plus importantes dans le bois juvenile. Malgre l'effet positif des coupes partielles sur la croissance annuelle, il n'a pas d'implications pratiques ni industrielles sur la qualite de la fibre et du bois d'epinette noire. Cette publication vise des lectorats des domaines academiques et industriels qui s'interessent aux impacts des pratiques sylvicoles sur la qualite du bois"
