Download or read book Nutrient Reduction and Biomanipulation as Tools to Improve Water Quality The Lake Ringsj n Story written by Lars-Anders Hansson and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells a story of a large lake affected by agricultural and urban activities that have led to severe eutrophication problems with nuisance blue-green algal blooms. Although it is a case study of Lake Ringsjön (southern Sweden), the background, problems and measures are applicable to many lakes throughout the world. From a limnological point of view, the Lake Ringsjön story began more than 100 years ago, and during the last 20 years the sampling program has been intense, providing a unique data set on how a lake responds to human activities. However, the Lake Ringsjön story is not only a case study, but also a historical record of the development of ecological theory and its application. Hence, the lake has been subject both to an extensive nutrient reduction programme and a biomanipulation by means of fish reduction. Here we aim at combining the unique limnological data set with the eutrophication process, the nutrient reduction programme and the biomanipulation in order to apply our empirical knowledge to future lake management measures.
Download or read book Food Webs written by Gary A. Polis and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the recent surge of activity in food web research fueled by new empirical data, this authoritative volume successfully spans and integrates the areas of theory, basic empirical research, applications, and resource problems. Written by recognized leaders from various branches of ecological research, this work provides an in-depth treatment of the most recent advances in the field and examines the complexity and variability of food webs through reviews, new research, and syntheses of the major issues in food web research. Food Webs features material on the role of nutrients, detritus and microbes in food webs, indirect effects in food webs, the interaction of productivity and consumption, linking cause and effect in food webs, temporal and spatial scales of food web dynamics, applications of food webs to pest management, fisheries, and ecosystem stress. Three comprehensive chapters synthesize important information on the role of indirect effects, productivity and consumer regulation, and temporal, spatial and life history influences on food webs. In addition, numerous tables, figures, and mathematical equations found nowhere else in related literature are presented in this outstanding work. Food Webs offers researchers and graduate students in various branches of ecology an extensive examination of the subject. Ecologists interested in food webs or community ecology will also find this book an invaluable tool for understanding the current state of knowledge of food web research.
Download or read book Ecological Stoichiometry written by Robert W. Sterner and published by Princeton University Press. This book was released on 2017-02-15 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, Ecological Stoichiometry is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. From the foreword by Peter Vitousek: ? "[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . And if we are both lucky and good, this questioning and testing will advance our field beyond the level achieved in this book. I can't wait to get on with it."

After an introduction to the basics of dynamic modeling, the book leads students through an analysis of several environmental problems, including surface-water pollution, matter-cycling disruptions, and global warming. The scientific and technical context is provided for each problem, and the methods for analyzing and designing appropriate modeling approaches is provided. While the mathematical content does not exceed the level of a first-semester calculus course, the book gives students all of the background, examples, and practice exercises needed both to use and understand environmental modeling. It is suitable for upper-level undergraduate and beginning-graduate level environmental professionals seeking an introduction to modeling in their field.
Download or read book Food Webs From Connectivity to Energetics written by and published by Elsevier. This book was released on 2005-05-16 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most recent volume of this series, Advances in Ecological Research, demonstrates a captivating knowledge of recent advances in the analysis of food webs. A food web describes the network of predator-prey interactions within a community. The simplest description of a food web specifies only who eats whom (a connectance web), with no indication of how much or how often. Chapters in this book begin with a discussion of the most detailed connectance webs ever compiled, and advance to incorporate information on the body size and numerical abundance of the species. The results yield new ways of describing food webs and powerful new models for estimating patterns of energy flow in ecosystems. - Provides fresh ways of describing food webs and applies previous observations in a new context - Ranked as the #1 publication in the Institute for Scientific Information in the Ecology section of 2000 - Powerful new theory AND application to some of the best food web data in the world - Many mathematical models for food web structure and function - Integrates previously unconnected perspectives on the description of ecological communities

Download or read book Food Webs and Container Habitats written by R. L. Kitching and published by Cambridge University Press. This book was released on 2000-08-03 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The animal communities in plant-held water bodies, such as tree holes and pitcher plants, have become models for food-web studies. In this book, Professor Kitching introduces us to these fascinating miniature worlds and demonstrates how they can be used to tackle some of the major questions in community ecology. Based on thirty years' research in many parts of the world, this work presents much previously unpublished information, in addition to summarising over a hundred years of natural history observations by others. The book covers many aspects of the theory of food-web formation and maintenance presented with field-collected information on tree holes, bromeliads, pitcher plants, bamboo containers and the axils of fleshy plants. It is a unique introduction for the field naturalist and a stimulating source treatment for graduate students and professionals working in the fields of tropical and other forest ecology, as well as entomology.
Download or read book Complex Evolutionary Dynamics in Urban Regional and Ecologic Economic Systems written by J. Barkley Rosser and published by Springer Science & Business Media. This book was released on 2011-06-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on the middle chapters from the first edition of J. Barkley Rosser's seminal work, From Catastrophe to Chaos, this book presents an unusual perspective on economics and economic analysis. Current economic theory largely depends upon assuming that the world is fundamentally continuous. However, an increasing amount of economic research has been done using approaches that allow for discontinuities such as catastrophe theory, chaos theory, synergetics, and fractal geometry. The spread of such approaches across a variety of disciplines of thought has constituted a virtual intellectual revolution in recent years. This book reviews the applications of these approaches in various subdisciplines of economics and draws upon past economic thinkers to develop an integrated view of economics as a whole from the perspective of inherent discontinuity.
Download or read book Body Size The Structure and Function of Aquatic Ecosystems written by Alan G. Hildrew and published by Cambridge University Press. This book was released on 2007-07-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Download or read book Shallow Lakes 95 written by Lech Kufel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow lakes differ from deep ones in many aspects of nutrient dynamics, biotic structure and interactions of various trophic levels. Though very common in European lowlands, shallow lakes attract inadequate attention from research teams. This book aims at filling gaps in our knowledge of the processes which take place in non-stratified lakes. It contains proceedings from the international conference `Shallow Lakes *95' held in Mikolajki, Poland, on 20-26 August 1995. In more than 50 original papers up-to-date views on eutrophication, degradation and recovery of shallow lakes are presented. The first four sections of the book (Nutrient fluxes, Biotic structure, Trophic interactions and Whole lake studies) deal with theoretical aspects of lake functioning while the fifth (Biomanipulation, restoration and management) is devoted to practical measures undertaken to improve water quality in shallow lakes. The book is therefore addressed to university biologists and ecologists and PhD students, as well as to managers involved in restoration of shallow lakes.
