Download or read book Applications of Physiological Ecology to Forest Management written by J. J. Landsberg and published by Elsevier. This book was released on 1997-01-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.
Download or read book Growth and Physiological Responses of Canopy Tree Species to Selection Harvests in a Northern Hardwood Forest written by Trevor A. Jones and published by . This book was released on 2006 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basal area increment (BAI) response of trees to gap creation was generally positive; however, there was a lag in BAI response which typically lasted between one and three years. Tree size was the best predictor of both pre-harvest BAI and BAI response to gap creation. Large trees had the greatest BAI but did not respond as positively to gap creation as smaller trees. Unexpectedly, it was observed that the BAI response of the more shade tolerant species was more positive than the less tolerant species. This may be related to species differences in canopy structure, with the deep crowns of shade tolerant species providing increased light interception following gap creation. The management of tolerant hardwood forests in central Ontario is typically done using the selection harvest system where no more than one third of the stand basal area is removed in each harvest while a balanced distribution of tree sizes and species is maintained to ensure continual stand development. Because regeneration is achieved through the manipulation of the understory light environment, the response of tree seedlings and saplings to changing light availability has been well studied. However, little is known about either the physiological acclimation processes or the growth responses of canopy trees to gap creation. This thesis examines the physiological acclimation and growth responses of large trees to selection management and addresses the factors that determine the temporal pattern and magnitude of the growth response. In order to better understand growth responses of large trees to gap creation an experiment examining canopy physiological and morphological acclimation to gap creation was conducted. Leaves within the lower portions of the canopy experienced gradual increases in area-based maximum photosynthetic rates, stomatal conductance, and leaf nitrogen. No change in these variables was observed that could not be accounted for by changes in leaf mass per unit area. Both the growth and physiological studies point to the importance of increases in incident light in the lower portions of the canopy, in conjunction with slow acclimation responses, as drivers of whole tree carbon gain and growth following selection harvests.
Download or read book An Atlas of the World s Conifers written by Aljos Farjon and published by BRILL. This book was released on 2013-11-11 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2014 Choice Magazine "Outstanding Academic Title" An Atlas of the World's Conifers is the first ever atlas of all known conifer species. It is based on locality information of ca. 37,000 collected herbarium specimens held in scientific institutions. As well as providing natural distribution maps for each species, Farjon and Filer give the reader comprehensive insight into the biogeography, diversity and conservation status of conifers on all continents, dispelling the widely held view that they are primarily a northern boreal plant group. Conifer diversity is analysed and presented with a taxonomic and geographic perspective. Distribution patterns are interpreted using the latest information on continental drift, dispersal and phylogeny. The entire dataset supporting the Atlas can be consulted and verified online. These data can also be used for further research and are an invaluable resource for anyone working on conifer systematics, biogeography or conservation. An Atlas of the World’s Conifers indicates the known distribution of all conifers including an analysis of their biogeography, diversity and conservation status. Also available from Brill is Aljos Farjon’s A Handbook of the World's Conifers, published in 2010 (ISBN 978 90 04 17718 5) which is a 2017 Choice Magazine "Outstanding Academic Title".
Download or read book Physiological Ecology of North American Plant Communities written by Brian F. Chabot and published by Springer. This book was released on 1985-04-04 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiological ecology is an exciting, rapidly developing field. This volume ably indicates the immense gaps in our knowledge in part through a compilation of current knowledge about how plants adapt to the environmental conditions of the various North American biomes. Single chapters consider Arctic, alpine, taiga, chaparral, grassland, deciduous forest, tropical and subtropical forest, marine beaches and dunes, and coastal marshes. Two chapters are devoted to Western forests and three to deserts. The short preface is a poor substitute for a thoughtful introduction and a summary is sorely missed. W.D. Billing's chapter on the history of plant ecophysiology is outstanding. The only remotely comparable single-volume work in English is Heinrich Walter's Vegetation of the Earth and Ecological Systems of the Geobiosphere (2nd ed., 1979; 1st ed., CH, Apr '74); the present volume fills in many details excluded in Walter's global treatment. A solid background in ecology and plant physiology is needed to comprehend at least half of each chapter; however, Chabot and Mooney provide an excellent reference work of use to advanced undergraduates, graduates, and faculty. Recommended for libraries in colleges with plant ecology, plant geography, or plant physiology courses.-G.D. Dreyer, Connecticut College--Choice Reviews.

Download or read book Plant Physiological Ecology written by Hans Lambers and published by Springer Nature. This book was released on 2019-12-11 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth, reproduction, and geographical distribution of plants are profoundly influenced by their physiological ecology: the interaction with the surrounding physical, chemical, and biological environments. This textbook highlights mechanisms that underlie plant physiological ecology at the levels of physiology, biochemistry, biophysics, and molecular biology. At the same time, the integrative power of physiological ecology is well suited to assess the costs, benefits, and consequences of modifying plants for human needs and to evaluate the role of plants in natural and managed ecosystems. Plant Physiological Ecology, Third Edition is significantly updated, with many full color illustrations, and begins with the primary processes of carbon metabolism and transport, plant water relations, and energy balance. After considering individual leaves and whole plants, these physiological processes are then scaled up to the level of the canopy. Subsequent chapters discuss mineral nutrition and the ways in which plants cope with nutrient‐deficient or toxic soils. The book then looks at patterns of growth and allocation, life‐history traits, and interactions between plants and other organisms. Later chapters deal with traits that affect decomposition of plant material and with the consequences of plant physiological ecology at ecosystem and global levels. Plant Physiological Ecology, Third Edition features several boxed entries that extend the discussions of selected issues, a glossary, and numerous references to the primary and review literature. This significant new text is suitable for use in plant ecology courses, as well as classes ranging from plant physiology to plant molecular biology.
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 Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.

Download or read book Forest Ecology written by Daniel M. Kashian and published by John Wiley & Sons. This book was released on 2023-03-13 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: FOREST ECOLOGY Authoritative resource covering traditional plant ecology topics and contemporary components such as climate change, invasive species, ecosystem services, and more Forest Ecology provides comprehensive coverage of the field, focusing on traditional plant ecology topics of tree structure and growth, regeneration, effects of light and temperature on tree physiology, forest communities, succession, and diversity. The work also reviews abiotic factors of light, temperature, physiography (landforms and topography), soil, and disturbance (especially fire), and provides coverage of ecosystem-level topics including carbon storage and balance, nutrient cycling, and forest ecosystem productivity. The 5th edition of Forest Ecology retains the readability and accessibility of the previous editions and includes important additional topical material that has surfaced in the field. All topics are approached with a landscape ecosystem or geo-ecological view, which places biota (organisms and communities) in context as integral parts of whole ecosystems that also include air (atmosphere and climate), topography, soil, and water. As such, the book fills a niche utilized by no other forest ecology text on the market, helping students and researchers consider whole ecosystems at multiple scales. Sample topics covered in Forest Ecology include: Contemporary components of forest ecology, including climate change, invasive species, diversity, ecological forestry, landscape ecology, and ecosystem services. Characteristics of physiography important for forest ecosystems, including its effects on microclimate, disturbance, soil, and vegetation. Genetic diversity of woody plants and genecological differentiation of tree species, including the importance of hybridization, polyploidy, and epigenetics. Site quality estimation using tree height and ground flora, and multiple-factor approaches to forest site and ecosystem classification and mapping. Forest Ecology is a highly accessible text for students, but it also serves as an excellent reference for academics. In addition, practitioners of forest ecology can also harness the information within to gain better insight into the field for practical application of concepts.

Download or read book Biodiversity and Ecosystem Function written by Ernst-Detlef Schulze and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.
