Book Synopsis Compensatory Growth: an Adaptation to Environmental Stress in Plants and Animals by : Chao Li
Download or read book Compensatory Growth: an Adaptation to Environmental Stress in Plants and Animals written by Chao Li and published by Frontiers Media SA. This book was released on 2024-03-27 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compensatory growth (CG) is defined as a change in growth rate (usually positive) following a period of reduced biomass or slowed growth due to some perturbation (e.g. nutrient deprivation, parasite load, tissue damage, or natural/anthropogenic disturbance). The phenomenon occurs throughout the plant and animal kingdoms, and while it is primarily observed in species with short lifespans, it has also been detected in longer-living organisms such as trees. CG occurs at the individual level as a variable life history trait but has the potential to impact the performance of whole populations and communities.

Download or read book Wood Variation written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.

Book Synopsis Climate Change Adaptation and Mitigation Management Options by : James M. Vose
Download or read book Climate Change Adaptation and Mitigation Management Options written by James M. Vose and published by CRC Press. This book was released on 2013-12-05 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.
Book Synopsis The Role of Insectivorous Birds in Forest Ecosystems by : James G. Dickson
Download or read book The Role of Insectivorous Birds in Forest Ecosystems written by James G. Dickson and published by Elsevier. This book was released on 2012-12-02 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Role of Insectivorous Birds in Forest Ecosystems is a publication of the proceedings of The Role of Insectivorous Birds in Forest Ecosystems symposium, held on July 13 and 14, 1978 at Nacogdoches, Texas. The proceedings discuss the ecology of insectivorous birds and acknowledge their roles in forest ecosystems. The book begins with an introduction to and history of insectivorous birds and their roles in forest ecosystems. It then discusses the sampling methods for bird and insect populations, bird foraging strategies, and ecology of insectivorous bird species and communities. This book will be helpful to forest managers in managing insectivorous birds. It is also especially valuable in formulating biological control strategies for use in forests.

Book Synopsis Non-wood Forest Products from Conifers by : William M. Ciesla
Download or read book Non-wood Forest Products from Conifers written by William M. Ciesla and published by Fao. This book was released on 1998 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this paper is to provide a global review of the non-wood uses of conifers. For the purposes of this paper, conifers are defined as trees and shrubs of the botanical orders Coniferales, Taxales and Ginkgoales (Rushforth 1987). Although some services are briefly mentioned, the focus of this paper is on products which conifers provide species, which are important sources of non-wood forest products, and places where these products are harvested. With the exception of essential oils, which can be obtained from several parts of the tree, the products described are organized by the part of the tree from which they are obtained (e.g. foliage, bark and roots, resin, seeds and cones). Where possible, data on levels of production and international trade are presented. Problems associated with the sustainable management of these products and compatibility or conflicts with other land uses are also presented. Both contemporary and historical or traditional uses of non-wood products from conifers are discussed.
Book Synopsis Guidelines for Precommercial Thinning of Douglas-fir by : Donald L. Reukema
Download or read book Guidelines for Precommercial Thinning of Douglas-fir written by Donald L. Reukema and published by . This book was released on 1975 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production of merchantable wood in even-aged Douglas-fir stands can be increased substantially by precommercial thinning. Guidelines for, and gains from, precommercial thinning both strongly depend on the size of trees wanted at the first commercial cut; the larger this size, (1) the fewer trees should be left after precommercial thinning, (2) the greater is the maximum age or tree size at which precommercial thinning is practical, and (3) the greater is the gain is usable yield from precommercial thinning. Also, generally, the longer the time required for a stand to reach commercial size without thinning, the greater the gains from precommercial thinning. These and other considerations are discussed, and procedures are recommended.
