Book excerpt: Evaluation of the biotic integrity of dynamic lotic environments is crucial to maintaining the successful functioning of watershed ecosystems. Routine biological monitoring is necessary to identify the influence of environmental degradation on aquatic life and measure the effects of both short and long-term environmental variation. Though New York State has a rich history of statutory biological monitoring along Hudson River tributaries, longitudinal analyses of benthic macroinvertebrate data using multidimensional scaling (MDS) and multimetric indices (MMI) are limited. Here, I use six family-level metric indices, multidimensional scaling (MDS) and indicator species analysis to evaluate biotic integrity along the Saw Kill River (Annandale, NY). Invertebrate collection took place between August 1st and September 2nd, 2017 at 3 distinct locations along the Saw Kill. Historical data from Budd and Strayer (1998) were incorporated into compositional analysis to assess the influence of global change, changing land-use, and land-use intensity on invertebrate communities. The results indicate a significant change in benthic macroinvertebrate communities of the Saw Kill over time as well as legacies of historical land-use in reported species composition and richness scores. Increasing evenness and richness of invertebrate communities at each site suggest an increase in biological integrity throughout the stream reach sampled despite evidence of global change. Although I do not demonstrate causal links between changing land-use (reforestation of catchment area, decreasing agricultural/mixed uses, etc.) and in-stream invertebrate composition, these data suggest linked changes. This study demonstrates the value of long-term longitudinal data sets and supports the conclusion that longitudinal biological assessment of lotic ecosystems can provide valuable insight into existing anthropogenic influences on riverine environments and the application of future watershed development plans.

Book excerpt: Global Integrity Project has brought together leading scientists and thinkers from around the world to examine the combined problems of threatened and unequal human well-being, degradation of the ecosphere, and unsustainable economies. Based on the proposition that healthy, functioning ecosystems are a necessary prerequisite for both economic security and social justice, the project is built around the concept of ecological integrity and its practical implications for policy and management. Ecological Integrity presents a synthesis and findings of the project. Contributors -- including Robert Goodland, James Karr, Orie Loucks, Jack Manno, William Rees, Mark Sagoff, Robert Ulanowicz, Philippe Crabbe, Laura Westra, David Pimentel, Reed Noss, and others -- examine the key elements of ecological integrity and consider what happens when integrity is lost or compromised. The book: examines historical and philosophical foundations of the concept of ecological integrity explores how integrity can be measured examines the relationships among ecological integrity, human health, and food production looks at economic and ethical issues that need to be considered in protecting ecological integrity offers concrete recommendations for reversing ecological degradation while promoting social and economic justice and welfare . Contributors argue that there is an urgent need for rapid and fundamental change in the ecologically destructive patterns of collective human behavior if society is to survive and thrive in coming decades. Ecological Integrity is a groundbreaking book that integrates environmental science, economics, law, and ethics in problem analysis, synthesis, and solution, and is a vital contribution for anyone concerned with interactions between human and planetary health.

Book excerpt: It is not possible to understand the apparent stability of the Earth's climate and environment unless we can fully understand how the best possible environmental conditions may be maintained for life to exist. Human colonization of areas with natural biota, for industrial or agricultural activities, will lead to degradation of those natural communities and violation of the BRE (biotic regulation of the environment) principle. Thus to maintain an environment on Earth that is suitable for life it is necessary to preserve and allow the natural recovery of natural biotic communities, both in the oceans and on land. This book is devoted to a quantitative version of the BRE concept, and is built on a foundation of modern scientific knowledge accumulated in the fields of physics and biology.

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: Today, efforts are being made to rehabilitate badly degraded ecosystems and protect areas which have important ecological value, such as national parks, critical fish and wildlife habitats, natural communities and endangered species. Since human values are an integral part of the decisions to protect or rehabilitate-the goals and objectives for such actions are often unclear. Concepts of "health," "integrity" and "diversity" express important values associated with management actions but they do not provide clear guidelines for these actions. The criteria developed and applied in this book provide guidelines and serve as a road map to anyone involved in ecosystem management-scientists, land managers and policy makers.

Book excerpt: Engineering within Ecological Constraints presents a rare dialogue between engineers and environmental scientists as they consider the many technical as well as social and legal challenges of ecologically sensitive engineering. The volume looks at the concepts of scale, resilience, and chaos as they apply to the points where the ecological life support system of nature interacts with the technological life support system created by humankind. Among the questions addressed are: What are the implications of differences between ecological and engineering concepts of efficiency and stability? How can engineering solutions to immediate problems be made compatible with long-term ecological concerns? How can we transfer ecological principles to economic systems? The book also includes important case studies on such topics as water management in southern Florida and California and oil exploration in rain forests. From its conceptual discussions to the practical experience reflected in case studies, this volume will be important to policymakers, practitioners, researchers, educators, and students in the fields of engineering, environmental science, and environmental policy.

Read this book as part of your essential research. Author Bill Dahl goes Beneath The Surface of Lake Chapala and shares what may not be obvious in your internet research, discussions with others, and international retirement living resources. YOU NEED TO READ THIS BOOK if you are considering Mexico for retirement - particularly if you are considering the Lake Chapala region. Bill reveals the documented environmental and public health hazards that inhabit the area. He delves into tourist safety, digital connectivity, infrastructure issues, problematic governance and corruption. This book provides detailed documentation of these issues and a road map for you to explore these issues - and others - on your own.Mexico is not unlike any other country on the planet; it possesses extraordinary positives it is proud to share with the world – and – it has current issues that it would rather not speak about. I encountered both. I adore Mexico. Particularly Guadalajara in the State of Jalisco. The people, culture, food, art, architecture,language and landscapes are precious to me. I did not travel to Mexico with this book in mind. The inspirations for this book found me – my heart and my mind. The motivation for this series was both unexpected and unintentional. Yet, when confronted with these realities, I knew I must write about them.I hope this book assists you in some way in your selection process of a place for you to retire in Mexico. Have a friend or relative thinking about retirement in Mexico's Lake Chapala area? Give them the gift of this book.Enjoy and safe travels. Enjoy the journey.

Available in PDF, EPUB and Kindle. Book excerpt: Dramatic changes have occurred in the functioning of larger rivers because of social values and policies, land use, inchannel causes, and alien species. These changes have resulted in the reduction in range and abundance of many native fish species. This book describes the historical changes observed in the fish assemblages of 27 large rivers in North, Central, and South America. A synthesizing chapter highlights common and distinct patterns among the rivers and their stressors. The book focuses on entire fish assemblages, including the many species that do not enter fisheries. It will be of interest to both fishery biologists and aquatic ecologists who are concerned with the status and trends in biodiversity and biointegrity. Contains historical information as well as new research and monitoring results, including research on metapopulations, genetics, and life history strategies.
