Download or read book Ecology of Shallow Lakes written by Marten Scheffer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework. The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems. Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University. Reviews `Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant `bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, `how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.' Simon Harrison in Journal of Ecology, 86 `The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls `mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.' Wolf Mooij in Aquatic Ecology, 32
Download or read book Cultural Materialism written by Marvin Harris and published by AltaMira Press. This book was released on 2001-08-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cultural Materialism, published in 1979, was Marvin Harris's first full-length explication of the theory with which his work has been associated. While Harris has developed and modified some of his ideas over the past two decades, generations of professors have looked to this volume as the essential starting point for explaining the science of culture to students. Now available again after a hiatus, this edition of Cultural Materialism contains the complete text of the original book plus a new introduction by Orna and Allen Johnson that updates his ideas and examines the impact that the book and theory have had on anthropological theorizing.
Download or read book Saving Nature s Legacy written by Reed F. Noss and published by Island Press. This book was released on 1994-04-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by two leading conservation biologists, Saving Nature's Legacy is a thorough and readable introduction to issues of land management and conservation biology. It presents a broad, land-based approach to biodiversity conservation in the United States, with the authors succinctly translating principles, techniques, and findings of the ecological sciences into an accessible and practical plan for action. After laying the groundwork for biodiversity conservation -- what biodiversity is, why it is important, its status in North America -- Noss and Cooperrider consider the strengths and limitations of past and current approaches to land management. They then present the framework for a bold new strategy, with explicit guidelines on: inventorying biodiversity selecting areas for protection designing regional and continental reserve networks establishing monitoring programs setting priorities for getting the job done Throughout the volume, the authors provide in-depth assessments of what must be done to protect and restore the full spectrum of native biodiversity to the North American continent.

Available in PDF, EPUB and Kindle. Book excerpt: In the wake of tensions between modern and postmodern sensibilities, what larger directions now emerge in cultural anthropology? In this major work, Bruce Knauft takes stock of important recent initiatives in cultural and critical theory. By combining critical reviews and ethnographic engagements with fresh readings of major figures and approaches, the work develops a larger vantage point for considering the dispersing influence of practice theories, postmodernism, cultural studies, postcolonial studies, modern/post-positive feminism, and multicultural criticisms.

Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Shows 55 color plates, documenting wetland indicators throughout the nation - with more than 34 soil plates and aerial photos Illustrates other wetland properties with more than 50 figures Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation Contents Wetland Definitions Wetland Concepts for Identification and Delineation Plant Indicators of Wetlands and Their Characteristics Vegetation Sampling and Analysis for Wetlands Soil Indicators of Wetlands Wetland Identification and Boundary Delineation Methods Problem Wetlands and Field Situations for Delineation Wetland Classification Wetlands of the United States: An Introduction, With Emphasis on Their Plant Communities Wetland Mapping and Photointerpretation

Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume handbook is a comprehensive account of the rapidly emerging and vibrant science of the ecological restoration of habitats and species. Ecological restoration aims to achieve complete structural, functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social, and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction, or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology in relation to manipulations and management of the biological, geophysical, and chemical framework.
