Book excerpt: Movement of nutrients among ecosystems is a key process that drives productivity and influences ecological dynamics. This dissertation explores two aspects of nutrient transfer among ecosystems: translocation by migratory species and landscape controls on terrestrial ecosystem losses. As migrants move among ecosystems they can transfer materials and energy that alter ecosystem dynamics and processes. Among fishes, salmon are well-known to transfer large quantities of nutrients from the ocean to their freshwater spawning grounds as they migrate and die en masse. Less is known about the role of fish that spawn multiple times over their life and thus do not leave large quantities of carcasses in their spawning grounds. Much of this dissertation explores the role of white and longnose suckers as nutrient vectors in Great Lakes tributaries. I documented the early life history of longnose suckers, pathways of nutrient contributions from sucker migrations, and ecosystem metabolic responses. I found that sucker eggs and excretion contribute large quantities of nutrients to their spawning streams. Because early life mortality is often >99% and larvae spend little time feeding in their spawning streams, most of these nutrients become available to stream biota. Sucker nutrient contributions were large relative to background availability, even in an agricultural watershed context, and they led to increased gross primary production but not ecosystem respiration. Landscape processes also exert important influence over the availability and transport of nutrients in streams. Human land use has transformed many stream ecosystems as agriculture and urban development supply nutrients and alter stream hydrology. In the Hawaiian archipelago, human land use overlays large gradients of substrate age, precipitation, and slope which are important determinants of nutrient availability in terrestrial ecosystems. I examined the relative importance of natural gradients and human land use in determining stream nutrient concentrations and found that weathering patterns remain the primary control over P availability across the landscape, but that human activities are more important for N.
Book Synopsis Riverine Ecosystem Management by : Stefan Schmutz
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Synopsis Contaminants and Ecological Subsidies by : Johanna M. Kraus
Download or read book Contaminants and Ecological Subsidies written by Johanna M. Kraus and published by Springer Nature. This book was released on 2020-10-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the effects of aquatic contaminants on ecological subsidies and food web exposure at the boundary of aquatic and terrestrial ecosystems. It provides the first synthesis of the findings and principles governing the “dark side” of contaminant effects on ecological subsidies. Furthermore, the volume provides extensive coverage of the tools being developed to help managers and researchers better understand the implications of contaminants movement and their effects on natural resources and ecosystem processes. Aquatic and terrestrial ecosystems are linked through movements of energy and nutrients which subsidize recipient food webs. As a result, contaminants that concentrate in aquatic systems because of the effects of gravity on water and organic matter have the potential to impact both aquatic and terrestrial ecosystem processes. Within the last decade, increased attention has been paid to this phenomenon, particularly the effects of aquatic contaminants on resource and contaminant export to terrestrial consumers, and the potential implications for management. This volume, curated and edited by three field leaders, incorporates empirical results, management applications and theoretical synthesis and is a key reference for academics, government researchers and consultants.

Book Synopsis Toward a Unified Ecology by : T. F. H. Allen
Download or read book Toward a Unified Ecology written by T. F. H. Allen and published by Columbia University Press. This book was released on 1992 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key demands are being made of ecology: that the discipline increasingly be a predictive one; and that ecologists be prepared to consider large-scale systems. These systems become simple or complex based on the level and type of explanation required, and a strict and consistent epistemology is needed in light of new insights into the nature of complexity. T. F. H. Allen and Thomas W. Hoekstra argue that complex systems analysis requires ecologists to distinguish models and to recognize that models must invoke a scale and point of view. Toward a Unified Ecology offers a strategy to attain a unity that brings basic ecology to bear on ecological management. Beginning with hierarchy theory as a basic premise, the book goes on to explain that the conventional "levels"--ecosystems, landscapes, communities, populations, organisms--are not levels in themselves but criteria for observation. The authors assert that the essential character of ecology's subdisciplines is scale-dependent. Putting scale back into systems of well-defined type captures the richness of the connections in the material ecological system. Allen and Hoekstra present a conceptual framework for a more coherent view of ecology, showing how to link the various parts of ecology into a natural whole.

Book Synopsis The Biology and Ecology of Streams and Rivers by : Alan Hildrew
Download or read book The Biology and Ecology of Streams and Rivers written by Alan Hildrew and published by Oxford University Press. This book was released on 2023-06-19 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.
