Book Description
Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.

Book Description
Woody plants such as trees have a significant economic and climatic influence on global economies and ecologies. This completely revised classic book is an up-to-date synthesis of the intensive research devoted to woody plants published in the second edition, with additional important aspects from the authors' previous book, Growth Control in Woody Plants. Intended primarily as a reference for researchers, the interdisciplinary nature of the book makes it useful to a broad range of scientists and researchers from agroforesters, agronomists, and arborists to plant pathologists and soil scientists. This third edition provides crutial updates to many chapters, including: responses of plants to elevated CO2; the process and regulation of cambial growth; photoinhibition and photoprotection of photosynthesis; nitrogen metabolism and internal recycling, and more. Revised chapters focus on emerging discoveries of the patterns and processes of woody plant physiology.* The only book to provide recommendations for the use of specific management practices and experimental procedures and equipment*Updated coverage of nearly all topics of interest to woody plant physiologists* Extensive revisions of chapters relating to key processes in growth, photosynthesis, and water relations* More than 500 new references * Examples of molecular-level evidence incorporated in discussion of the role of expansion proteins in plant growth; mechanism of ATP production by coupling factor in photosynthesis; the role of cellulose synthase in cell wall construction; structure-function relationships for aquaporin proteins

Book Description
The authors provide descriptions and sketches of most of the native and exotic plants that can be found or grown in the Great Plains. A concise paragraph is included for each species to provide information about plant size and habit, date of bloom, foliage color, site requirements, zone of adaptation, and landscape use.

Book Description
Winner, 2018 Carroll Abbott Memorial Award, sponsored by the Native Plant Society of Texas The Trans-Pecos region of Texas is home to a variety of big game species, including desert mule deer, pronghorn, desert bighorn sheep, white-tailed deer, elk, feral hog, and javelina; several species of exotics, such as aoudad, axis deer, and blackbuck antelope; and domestic livestock that includes cattle, horses, goats, sheep, and bison. Prepared by a team of range specialists at the Borderlands Research Institute in Alpine, Texas, this field guide will allow the area’s ranch managers, private landowners, resource professionals, students, and other outdoor enthusiasts to identify the key woody plants that serve as valuable forage for these animals. Encompassing 18 West Texas counties, with application in like habitats in the western Hill Country and southern Rolling Plains as well as in northern Mexico and eastern New Mexico, the book provides a thorough introduction to the natural features of the region and descriptions, nutrition values, and management prescriptions for 84 species of browse plants. In addition to informing readers about the diet of the region’s large animals, this fully illustrated, user-friendly reference also intends to inspire the continued good stewardship of the land they inhabit.

Book Description
This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.

Book Description
A comprehensive guide that includes a vast range of species and plant communities and employs thorough, original keys. Based primarily on vegetative characteristics, the keys don't require that flowers or other reproductive features be present, like many plant guides. And this guide's attention to woody plants as a whole allows one to identify a much greater variety of plants. That especially suits an arid region such as Utah with less diverse native trees. Woody plants are those that have stems that persist above ground even through seasons that don't favor growth, due to low precipitation or temperatures. Woody Plants of Utah employs dichotomous identification keys that are comparable to a game of twenty questions. They work through a process of elimination by choosing sequential alternatives. Detailed, illustrated plant descriptions complement the keys and provide additional botanical and environmental information in relation to a useful introductory categorization of Utah plant communities. Supplementary tools include photos, distribution maps, and an illustrated glossary.

Book Description
The processes and mechanisms that control the growth of woody plants are of crucial importance for both economic and biological reasons. The comprehensive coverage of Growth Control in Woody Plants includes discussion of the growth controlling factors in both reproductive structures (flowers, fruit, seeds, pollen, etc.) and vegetative organs (stems, branches, leaves, and roots). Other major topics covered include seed germination, seedling growth, physiological and environmental regulation of growth, cultural practices, and biotechnology.This comprehensive treatment of the many factors that control the growth of woody plants can serve both as a valuable text and as a frequently used reference.* Includes comprehensive representation of a broad subject* Provides thorough bibliographic coverage * Well illustrated* Serves as a vital companion to Physiology of Woody Plants, Second Edition
