Download or read book Oaks Physiological Ecology Exploring the Functional Diversity of Genus Quercus L written by Eustaquio Gil-Pelegrín and published by Springer. This book was released on 2017-12-12 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.

Download or read book Trees in a Changing Environment written by Michael Tausz and published by Springer. This book was released on 2014-08-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers current state-of-the-science knowledge of tree ecophysiology, with particular emphasis on adaptation to a novel future physical and chemical environment. Unlike the focus of most books on the topic, this considers air chemistry changes (O3, NOx, and N deposition) in addition to elevated CO2 effects and its secondary effects of elevated temperature. The authors have addressed two systems essential for plant life: water handling capacity from the perspective of water transport; the coupling of xylem and phloem water potential and flow; water and nutrition uptake via likely changes in mycorrhizal relationships; control of water loss via stomata and its retention via cellular regulation; and within plant carbon dynamics from the perspective of environmental limitations to growth, allocation to defences, and changes in partitioning to respiration. The authors offer expert knowledge and insight to develop likely outcomes within the context of many unknowns. We offer this comprehensive analysis of tree responses and their capacity to respond to environmental changes to provide a better insight in understanding likelihood for survival, as well as planning for the future with long-lived, stationary organisms adapted to the past: trees.

Download or read book Quercus Genetics written by Mary V Ashley and published by Mdpi AG. This book was released on 2022-01-14 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Quercus (Quercus, Fagaceae) comprises more than 400 species distributed throughout the northern hemisphere. While the highest oak diversity occurs in American and Asia, European species are also widespread. Oaks are ecological dominants of many temperate forests, and evergreen species are major components of Mediterranean and subtropical woodlands. They provide important ecosystem services and valuable timber. Oak species exhibit high genetic diversity, and this diversity has provided a wealth of information regarding oak ecology and evolution. Recent genetic and genomic studies of oaks have unraveled their evolutionary origins, history, and past radiations. Genetic approaches have also been applied to learn about more recent events, such as range expansions and contractions occurring at northern latitudes.

Download or read book Population Genetics of Forest Trees written by W.T. Adams and published by Springer Science & Business Media. This book was released on 1992-11-30 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.
Download or read book For the Health of the Land written by Aldo Leopold and published by Island Press. This book was released on 2012-07-16 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold's classic work A Sand County Almanac is widely regarded as one of the most influential conservation books of all time. In it, Leopold sets forth an eloquent plea for the development of a "land ethic" -- a belief that humans have a duty to interact with the soils, waters, plants, and animals that collectively comprise "the land" in ways that ensure their well-being and survival. For the Health of the Land, a new collection of rare and previously unpublished essays by Leopold, builds on that vision of ethical land use and develops the concept of "land health" and the practical measures landowners can take to sustain it. The writings are vintage Leopold -- clear, sensible, and provocative, sometimes humorous, often lyrical, and always inspiring. Joining them together are a wisdom and a passion that transcend the time and place of the author's life. The book offers a series of forty short pieces, arranged in seasonal "almanac" form, along with longer essays, arranged chronologically, which show the development of Leopold's approach to managing private lands for conservation ends. The final essay is a never before published work, left in pencil draft at his death, which proposes the concept of land health as an organizing principle for conservation. Also featured is an introduction by noted Leopold scholars J. Baird Callicott and Eric T. Freyfogle that provides a brief biography of Leopold and places the essays in the context of his life and work, and an afterword by conservation biologist Stanley A. Temple that comments on Leopold's ideas from the perspective of modern wildlife management. The book's conservation message and practical ideas are as relevant today as they were when first written over fifty years ago. For the Health of the Land represents a stunning new addition to the literary legacy of Aldo Leopold.
Download or read book Forest Genomics and Biotechnology written by Isabel Allona and published by Frontiers Media SA. This book was released on 2019-11-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic addresses research in genomics and biotechnology to improve the growth and quality of forest trees for wood, pulp, biorefineries and carbon capture. Forests are the world’s greatest repository of terrestrial biomass and biodiversity. Forests serve critical ecological services, supporting the preservation of fauna and flora, and water resources. Planted forests also offer a renewable source of timber, for pulp and paper production, and the biorefinery. Despite their fundamental role for society, thousands of hectares of forests are lost annually due to deforestation, pests, pathogens and urban development. As a consequence, there is an increasing need to develop trees that are more productive under lower inputs, while understanding how they adapt to the environment and respond to biotic and abiotic stress. Forest genomics and biotechnology, disciplines that study the genetic composition of trees and the methods required to modify them, began over a quarter of a century ago with the development of the first genetic maps and establishment of early methods of genetic transformation. Since then, genomics and biotechnology have impacted all research areas of forestry. Genome analyses of tree populations have uncovered genes involved in adaptation and response to biotic and abiotic stress. Genes that regulate growth and development have been identified, and in many cases their mechanisms of action have been described. Genetic transformation is now widely used to understand the roles of genes and to develop germplasm that is more suitable for commercial tree plantations. However, in contrast to many annual crops that have benefited from centuries of domestication and extensive genomic and biotechnology research, in forestry the field is still in its infancy. Thus, tremendous opportunities remain unexplored. This Research Topic aims to briefly summarize recent findings, to discuss long-term goals and to think ahead about future developments and how this can be applied to improve growth and quality of forest trees.

Download or read book Thinking Like a Mountain written by Susan L. Flader and published by Univ of Wisconsin Press. This book was released on 1994-08-01 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: When initially published more than twenty years ago, Thinking Like a Mountain was the first of a handful of efforts to capture the work and thought of America's most significant environmental thinker, Aldo Leopold. This new edition of Susan Flader's masterful account of Leopold's philosophical journey, including a new preface reviewing recent Leopold scholarship, makes this classic case study available again and brings much-deserved attention to the continuing influence and importance of Leopold today. Thinking Like a Mountain unfolds with Flader's close analysis of Leopold's essay of the same title, which explores issues of predation by studying the interrelationships between deer, wolves, and forests. Flader shows how his approach to wildlife management and species preservation evolved from his experiences restoring the deer population in the Southwestern United States, his study of the German system of forest and wildlife management, and his efforts to combat the overpopulation of deer in Wisconsin. His own intellectual development parallels the formation of the conservation movement, reflecting his struggle to understand the relationship between the land and its human and animal inhabitants. Drawing from the entire corpus of Leopold's works, including published and unpublished writing, correspondence, field notes, and journals, Flader places Leopold in his historical context. In addition, a biographical sketch draws on personal interviews with family, friends, and colleagues to illuminate his many roles as scientist, philosopher, citizen, policy maker, and teacher. Flader's insight and profound appreciation of the issues make Thinking Like a Mountain a standard source for readers interested in Leopold scholarship and the development of ecology and conservation in the twentieth century.
Download or read book The Wealth of Nature written by Donald Worster and published by Oxford University Press. This book was released on 1994-10-27 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hailed as "one of the most eminent environmental historians of the West" by Alan Brinkley in The New York Times Book Review, Donald Worster has been a leader in reshaping the study of American history. Winner of the prestigious Bancroft Prize for his book Dust Bowl, Worster has helped bring humanity's interaction with nature to the forefront of historical thinking. Now, in The Wealth of Nature, he offers a series of thoughtful, eloquent essays which lay out his views on environmental history, tying the study of the past to today's agenda for change. The Wealth of Nature captures the fruit of what Worster calls "my own intellectual turning to the land." History, he writes, represents a dialogue between humanity and nature--though it is usually reported as if it were simple dictation. Worster takes as his point of departure the approach expressed early on by Aldo Leopold, who stresses the importance of nature in determining human history; Leopold pointed out that the spread of bluegrass in Kentucky, for instance, created new pastures and fed the rush of American settlers across the Appalachians, which affected the contest between Britain, France, and the U.S. for control of the area. Worster's own work offers an even more subtly textured understanding, noting in this example, for instance, that bluegrass itself was an import from the Old World which supplanted native vegetation--a form of "environmental imperialism." He ranges across such areas as agriculture, water development, and other questions, examining them as environmental issues, showing how they have affected--and continue to affect--human settlement. Environmental history, he argues, is not simply the history of rural and wilderness areas; cities clearly have a tremendous impact on the land, on which they depend for their existence. He argues for a comprehensive approach to understanding our past as well as our present in environmental terms. "Nostalgia runs all through this society," Worster writes, "fortunately, for it may be our only hope of salvation." These reflective and engaging essays capture the fascination of environmental history--and the beauty of nature lost or endangered--underscoring the importance of intelligent action in the present.
