Available in PDF, EPUB and Kindle. Book excerpt: We sampled seven intact nonriverine wet hardwood forests to establish target ranges for vegetation, soils and hydrology and to examine trends in plant species composition along a wetness gradient. Although quantitative vegetation analysis for this community has been published, broad drainage classes were used to represent a moisture gradient. We investigated trends along a finer-scaled wetness gradient utilizing a novel wetness index that incorporated indicators of saturated soils. Understanding small-scale patterns in plant community composition is useful in planning wetland restoration projects. Although no strong relationship was found between wetness index classes and plant community composition, these data represent the vegetative community supported by soils specific to each wetness class. Absence of this relationship is most likely a result of the dominance of A. rubrum and L. styraciflua in all wetness classes as well as a history of disturbance in each forest and other unknown stochastic variables. For the restorationist hoping to restore a historic nonriverine wet hardwood forest, once known as oak flats, we can suggest guidelines for restoring hydrology to the wetness classes in which we found oaks with high importance.

Download or read book Natural Variation of Hydrology in Nonrivierine Wet Hardwood Forests and the Implications for Restoration written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetland restoration projects across the United States are failing. Restored sites commonly lack the species and hydrology of the targeted community being restored. A better understanding of natural wetlands would help restoration project designers achieve community composition and hydrologic regimes that more closely resemble natural conditions. I investigated two different methods to identify patterns in hydrologic regime useful to restoration design. The first method was based on success criteria commonly used by North Carolina wetland mitigation projects. The second method was based on The Nature Conservancyââ'¬â"¢s Indicators of Hydrologic Alteration. In order to test these two methods, I collected hydrologic and compositional data across the natural variation of nonriverine wet hardwood forest stands, a rare wetland community type commonly restored in North Carolina. My results show that hydrologic parameters from the first method, based on current success criteria used in North Carolina, are not related to community composition. Hydrologic parameters from the second method, e.g. the maximum water table level over a 3-day span, explained much of the variation in nonriverine wet hardwood forest community composition. My results found that clear relationships do exist between hydrologic regime and community composition. Hydrologic parameters that are related to community composition need to be used as success criteria in future restoration designs. This will ensure that projects establish the appropriate hydrologic regime necessary to foster the desired wetland community type.

Download or read book The Longleaf Pine Ecosystem written by Shibu Jose and published by Springer Science & Business Media. This book was released on 2006-05-18 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The longleaf pine ecosystem, once one of the most extensive ecosystems in North America, is now among the most threatened. Over the past few centuries, land clearing, logging, fire suppression, and the encroachment of more aggressive plants have led to an overwhelming decrease in the ecosystem’s size, to approximately 2.2% of its original coverage. Despite this devastation, the range of the longleaf still extends from Virginia to Texas. Through the combined efforts of organizations such as the USDA Forest Service, the Longleaf Alliance, and the Nature Conservancy, extensive programs to conserve, restore, and manage the ecosystem are currently underway. The longleaf pine ecosystem is valued not only for its aesthetic appeal, but also for its outstanding biodiversity, habitat value, and for the quality of the longleaf pine lumber. It has a natural resistance to fire and insects, and supports more than thirty threatened or endangered plant and animal species, including the red-cockaded woodpecker and the gopher tortoise. The Longleaf Pine Ecosystem unites a wealth of current information on the ecology, silviculture, and restoration of this ecosystem. The book also includes a discussion of the significant historical, social, and political aspects of ecosystem management, making it a valuable resource for students, land managers, ecologists, private landowners, government agencies, consultants, and the forest products industry. About the Editors: Dr. Shibu Jose is Associate Professor of Forest Ecology and Dr. Eric J. Jokela is Professor of Silviculture at the School of Forest Resources and Conservation at the University of Florida in Gainesville. Dr. Deborah L. Miller is Associate Professor of Wildlife Ecology in the Department of Wildlife Ecology and Conservation at the University of Florida in Milton.

Available in PDF, EPUB and Kindle. Book excerpt: This volume aims to present the essential work of geographer and historical ecologist William M. Denevan to explain the impact and influence his thinking had on the conceptual advancement not only in his own discipline, but in a range of related disciplines such as anthropology, archaeology, and environmental history. The book is organized around eight themes, demonstrating Denevan’s early and profound insights on topics that remain of current relevance today, and the scholarly impact his writing had on subsequent scholarship. The book is unique because it offers commentary from active scholars who address the impacts of Prof. Denevan's thinking and work on contemporary environmental and ecological issues, with a focus on several groundbreaking themes (e.g. historical demography, agricultural landforms, cultural plant geography, human environmental impacts, indigenous agro-ecology, tropical agriculture, livestock and landscape, and synthetic contributions). This book will be of interest to a range of scholars in geography, anthropology, archaeology, history, and ecology, as well as to environmental managers and practitioners, especially those working for non-profit organizations and government organizations tasked with finding ways to adapt to global environmental change.
Download or read book Handbook for the Analysis of Micro Particles in Archaeological Samples written by Amanda G. Henry and published by Springer Nature. This book was released on 2020-07-07 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology. Topics covered in this handbook include diatom microfossils, starch granules, pollen grains, phytoliths, natural fibers, volcanic glass, minerals, insect remains, and feathers. Archaeological investigations increasingly rely on specialist identification of microscopic remnants found in sites. These micro-particles can provide information about the site environment and human activities that may not be apparent from artifacts and materials preserved on the macro-scale, and have given us new, and often high-profile, information about our past. The investigation of this "invisible archaeology" - that is, invisible to the naked eye - is still somewhat new, and generally each kind of micro-particle is studied individually. Researchers become experts in a narrow range of micro-particle types, but may be less familiar with, or even completely unaware of, the multitude of other forms that are frequently encountered in archaeological samples. This handbook’s accessible approach is suitable for those at the beginner level.
Download or read book Ecological Systems written by Rik Leemans and published by Springer Science & Business Media. This book was released on 2012-12-12 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth is home to an estimated 8 million animal species, 600,000 fungi, 300,000 plants, and an undetermined number of microbial species. Of these animal, fungal, and plant species, an estimated 75% have yet to be identified. Moreover, the interactions between these species and their physical environment are known to an even lesser degree. At the same time, the earth’s biota faces the prospect of climate change, which may manifest slowly or extremely rapidly, as well as a human population set to grow by two billion by 2045 from the current seven billion. Given these major ecological changes, we cannot wait for a complete biota data set before assessing, planning, and acting to preserve the ecological balance of the earth. This book provides comprehensive coverage of the scientific and engineering basis of the systems ecology of the earth in 15 detailed, peer-reviewed entries written for a broad audience of undergraduate and graduate students as well as practicing professionals in government, academia, and industry. The methodology presented aims at identifying key interactions and environmental effects, and enabling a systems-level understanding even with our present state of factual knowledge.

Download or read book Environmental Flow Assessment written by John G. Williams and published by John Wiley & Sons. This book was released on 2019-06-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.
Download or read book Vascular Plants as Epiphytes written by Ulrich Lüttge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his lectures my teacher Karl Mägdefrau used to say that one only becomes a real plant scientist when one enters a tropical rainforest. For me this initiation occurred in 1969 in northern Queensland, Australia, and was associated with the greatest excitement. On another level it received confirmation when I set out in 1983 together with some friends and colleagues for the first detailed ecophysiological studies of epiphytes in the wet tropics in situ in the island of Trinidad and later for similar work in Venezuela. This then promoted the idea of organizing a special symposium on "The evolution and ecophysiology of vascular plants as epiphytes" during the XIV International Botanical Congress in luly 1987 in Berlin, and to ask some of the speakers to produce chapters for a small monograph on the interesting ecologically defined group of plants "epiphytes" as presented in this volume of "Ecological Studies". The enthusiasm of the participants of the symposium giving reports and adding to the discussion was most stimulating, and it appears that epiphytes might gain well-deserved, wider consideration in the future. The cooperation with the authors of this book was very pleasant and I appreciated the new contacts established with adepts of the "epiphyte community". The chapters were organized and arranged covering first more gen eral aspects with setting the scene in Chapter 1, the evolution of epi phytism in Chapter 2 and the role of CO -concentrating mechanisms in 2 Chapter 3.
