Available in PDF, EPUB and Kindle. Book excerpt: Lee Frelich provides a major contribution to the study of temperate-zone forest dynamics by considering three important themes: the combined influence of wind, fire, and herbivory on the successional trajectories and structural characteristics of forests; the interaction of deciduous and evergreen tree species to form mosiacs; and the significance of temporal and spatial scale with regard to the overall impact of disturbances. These themes are explored via case studies from the forests in the Lake States of Minnesota, Wisconsin and Michigan, where the presence of large primary forest remnants provides a unique opportunity to study the long-term dynamics of near-boreal, pine, and hardwood-hemlock forests.

This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. to the Present). Many previous research efforts in paleoecology have used plant-fossil evidence as proxy information for primarily geologic or climatic reconstructions or as a bio stratigraphic basis for correlation of regional events. In contrast, in this book, we deal with ecological questions that require a holistic perspective that integrates the interactions of biota with their dynamically changing environments over time scales up to tens of thousands of years. In the FORMAP Project, our major research objective has been to use late-Quaternary plant-ecological data sets to evaluate long-term patterns and processes in forest de velopment. In order to accomplish this objective, we have prepared subcontinent-scale calibrations that quantitatively relate the production and dispersal of arboreal pollen to dominance in the vegetation for the major tree types of eastern North America. Quantification of pollen-vegetation relationships provides a basis for developing quan titative plant-ecological data sets that allow further ecological analysis of both individual taxa and forest communities through time. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.

Download or read book Diversity and Dynamics in Forest Ecosystems written by Munesh Kumar and published by CRC Press. This book was released on 2021-12-28 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a wealth of in-depth knowledge of forest ecosystems, this new volume explores a collection of important topics on forest community dynamics. It looks at the diversity of forest ecosystems and explores such aspects as forest products in enhancing local livelihoods and community participation, forage production, forest conservation and sustainable management, regeneration patterns, seed handling, and more. Chapters in Diversity and Dynamics in Forest Ecosystems present new research on forest products, livelihood generation mechanisms of forest-dependent communities, utilization patterns of untapped resources from forests, and the structure of different ecosystems from the tropical to the temperate landscape. This book also features different drivers of community dynamics, such as the role of seed handling in forests, the influence of altitudinal variations, and protected and community-conserved forests on the forest diversity. Chapters also consider the role of non-timber forest products and their significance in livelihood diversification for tribal communities and forage crop genetic resources, and forest resource extraction by forest fringe dwellers. Also explored are aspects of soil organic carbon in agroforestry systems and integrated approaches of sustainable agroforestry development in diverse forest ecosystems. This edition also examines the vegetation structure and regeneration aspects of timberline zone, including diversity of herbaceous flora along the altitudinal gradient. The abundance of in-depth knowledge of the diversity and dynamics of forest ecosystems in this volume will be valuable in conservation and management of forests, which play an important role in the world environment. Forests are presently facing multiple disturbances, and this volume will help forestry professionals and others formulate further strategies to mitigate global climate change and other challenges.

Download or read book Forest Dynamics Growth and Yield written by Hans Pretzsch and published by Springer Science & Business Media. This book was released on 2009-06-19 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.
Download or read book The Ecology of Natural Disturbance and Patch Dynamics written by Steward T.A. Pickett and published by Elsevier. This book was released on 2013-10-22 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.

This book was released on 1998 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind disturbance plays a fundamental role in shaping forest dynamics in southeast Alaska. Recent studies have increased our appreciation for the effects of wind at both large and small scales. Current thinking is that wind disturbance characteristics change over a continuum dependent on landscape features (e.g. exposure, landscape position, topography). Data modeling has revealed the existance of fistinct wind disturbance regimes, grading from exposed landscapes where recurrent, large-scale wind events prevail to wind-protected landscapes where small-scale canopy gaps predominate. Emulating natural disturbances offers a way to design future management plans and silvicultural prescriptions consistent with prevailing ecological conditions.

Download or read book Arthropods of Tropical Forests written by Yves Basset and published by Cambridge University Press. This book was released on 2003-01-23 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.

Download or read book Measuring and Modeling Fine Root Dynamics in Temperate Forests written by Michael Luke McCormack and published by . This book was released on 2012 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperate forests represent a major ecological and economic resource across much of the globe. As in many ecosystems, below ground ecology in temperate forests is poorly understood and quantification of many biogeochemical fluxes below ground may be weakly constrained. Fine roots control plant uptake of soil resources such as water and nutrients as well as a major flux of carbon from plants into soil through production and turnover. However, basic patterns of fine root dynamics across species remain elusive and model incorporation of these processes may be inadequate. We address these limitations through both field observations and modeling activities. In Chapter 2 we identified relationships between fine root lifespan with plant growth rate, stem wood density, root diameter, and root nitrogen to carbon ratios across 12 temperate species grown in a common garden in central Pennsylvania, USA. We then further explored the relationships between timing and interannual variation in the amount of root production with different measures of fine root turnover in Chapter 3. Here, results indicated that despite relatively little attention previously given to patterns of root phenology and production, both may have strong effects on root turnover rates in temperate forests and potentially across most perennial plant ecosystems. We then conducted a sensitivity test of four different models of terrestrial biogeochemistry to adjustments in fine root turnover rates and discovered that reasonable adjustments of root turnover rate resulted in substantial changes in total systems carbon (i.e. all live and dead plant carbon plus all soil carbon) that were greater than 30% in some cases (Chapter 4). Finally, given the uncertainty in model parameterizations of fine root dynamics, in Chapter 5 we developed a method to describe fine root lifespan and turnover at broad spatial scales using known distributions of temperate tree species combined with species-specific estimates of root dynamics estimated using direct observations and patterns discovered in Chapters 2 and 3. Future efforts should expand to better appreciate how climate and edaphic factors drive variation in fine root dynamics within species and broadly across sites.
Download or read book Vegetation Dynamics written by Derek Eamus and published by Cambridge University Press. This book was released on 2016-03-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding ecosystem structure and function requires familiarity with the techniques, knowledge and concepts of the three disciplines of plant physiology, remote sensing and modelling. This is the first textbook to provide the fundamentals of these three domains in a single volume. It then applies cross-disciplinary insights to multiple case studies in vegetation and landscape science. A key feature of these case studies is an examination of relationships among climate, vegetation structure and vegetation function, to address fundamental research questions. This book is for advanced students and researchers who need to understand and apply knowledge from the disciplines of plant physiology, remote sensing and modelling. It allows readers to integrate and synthesise knowledge to produce a holistic understanding of the structure, function and behaviour of forests, woodlands and grasslands.
