Trophic Cascades by John Terborgh,James A Estes Pdf

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Trophic Cascade by Camille T. Dungy Pdf

“A soulful reckoning for our twenty-first century, held in focus through echoes of the past and future, but always firmly rooted in now.” —Yusef Komunyakaa, Pulitzer Prize-winning poet Winner of the Colorado Book Award in Poetry (2018) In this fourth book in a series of award-winning survival narratives, Dungy writes positioned at a fulcrum, bringing a new life into the world even as her elders are passing on. In a time of massive environmental degradation, violence and abuse of power, a world in which we all must survive, these poems resonate within and beyond the scope of the human realms, delicately balancing between conflicting loci of attention. Dwelling between vibrancy and its opposite, Dungy writes in a single poem about a mother, a daughter, Smokin’ Joe Frazier, brittle stars, giant boulders, and a dead blue whale. These poems are written in the face of despair to hold an impossible love and a commitment to hope. A readers companion will be available at wesleyan.edu/wespress/readerscompanions. “Dungy asks how we can survive despair and finds her answers close to the earth.” —Diana Whitney, The Kenyon Review “Trophic Cascade frequently bears witness—to violence, to loss, to environmental degradation—but for Dungy, witnessing entails hope.” —Julie Swarstad Johnson, Harvard Review Online “Tension. Simmering. Beneath her matter-of-fact, easy-going, sit-yourself-down, let-me-tell-it-like-it-is clarifying. And her power we take deadly seriously.” —Matt Sutherland, Foreword Reviews “[Trophic Cascade] asks us, in spite of the pain or difficulty of being human today, to find joy and vibrancy in our experiences.” —Elizabeth Flock, PBS Newshour

Large Carnivores and the Conservation of Biodiversity by Justina Ray,Kent H. Redford,Robert Steneck,Joel Berger Pdf

Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.

Routledge Handbook of Rewilding by Sally Hawkins,Ian Convery,Steve Carver,Rene Beyers Pdf

This handbook provides a comprehensive overview of the history, theory, and current practices of rewilding. Rewilding offers a transformational paradigm shift in conservation thinking, and as such is increasingly of interest to academics, policymakers, and practitioners. However, as a rapidly emerging area of conservation, the term has often been defined and used in a variety of different ways (both temporally and spatially). There is, therefore, the need for a comprehensive assessment of this field, and the Routledge Handbook of Rewilding fills this lacuna. The handbook is organised into four sections to reflect key areas of rewilding theory, practice, and debate: the evolution of rewilding, theoretical and practical underpinnings, applications and impacts, and the ethics and philosophy of rewilding. Drawing on a range of international case studies the handbook addresses many of the key issues, including land acquisition and longer-term planning, transitioning from restoration (human-led, nature enabled) to rewilding (nature-led, human enabled), and the role of political and social transformational change. Led by an editorial team who have extensive experience researching and practising rewilding, this handbook is essential reading for students, academics and practitioners interested in rewilding, ecological restoration, natural resource management and conservation.

Trophic Ecology by James E. Garvey,Matt Whiles Pdf

This book is a bridge between ecological paradigms – organismal/community approaches to food web dynamics and ecosystem-level approaches to production. The unification of organismal, community, and ecosystem approaches in ecology is emerging due to the growing availability of new techniques for assessing trophic interactions and their implications for ecosystems. Trophic Ecology is a formal text for both newcomers to the discipline as well as seasoned professionals looking for new ideas and refreshers on old topics. A wide range of topics are explained including autotrophy, heterotrophy, omnivory, decomposition, foraging behavior and theory, trophic cascades, bioenergetics, and production. The audience is upper-level undergraduate students and entry-level graduate students interested in autecological, organismal approaches to ecology, community and ecosystem ecology. It is also a reference text for instructors teaching upper-division courses, providing examples from the literature, quantitative approaches to teach, and new hypotheses yet to be fully tested by ecologists.

Eutrophication: Causes, Consequences and Control by Abid A. Ansari,Sarvajeet Singh Gill Pdf

Eutrophication continues to be a major global challenge and the problem of eutrophication and availability of freshwater for human consumption is an essential ecological issue. The global demand for water resources due to increasing population, economic developments, and emerging energy development schemes has created new environmental challenges for global sustainability. Accordingly, the area of research on eutrophication has expanded considerably in recent years. Eutrophication, acidification and contamination by toxic substances are likely to pose increasing threats to freshwater resources and ecosystems. The consequences of anthropogenic-induced eutrophication of freshwaters are severe deterioration of surface waters and growing public concern, as well as new interest among the scientific community. “Eutrophication: causes, consequences & control” provides the latest information on many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. This book offers a cutting-edge resource for researchers and students alike who are studying eutrophication in various ecosystems. It presents the latest trends and developments in the field, including: global scenarios and local threats to the dynamics of aquatic ecosystems, economics of eutrophication, eutrophication in the great lakes of the Chinese pacific drainage basin, photoautotrophic productivity in eutrophic ecosystems, eutrophication’s impacts on natural metal remediation in salt marshes, phytoplankton assemblages as an indicator of water quality in seven temperate estuarine lakes in southeast Australia, biogeochemical indicators of nutrient enrichments in wetlands – the microbial response as a sensitive indicator of wetland eutrophication, and ultraviolet radiation and bromide as limiting factors in eutrophication processes in semi-arid climate zones. Written by respected experts and featuring helpful illustrations and photographs, “Eutrophication: causes, consequences & control” provides a concise and practical update on the latest developments in eutrophication.

Carnivoran Ecology by Steven W. Buskirk Pdf

These charismatic mammals, which include dogs, cats, hyenas, weasels, mongooses, seals, sea lions and bears, have always held special importance to humans throughout history and continue to do so today. In recent decades, the emergence of new technologies has completely transformed our knowledge of how carnivorans interact with their environments and consequently reshaped our view of carnivoran ecology. This unique synthesis uses examples from a diverse and expanding carnivoran literature, drawing from all carnivoran families and spanning the world's oceans and continents, to produce a clearly written and richly illustrated book that reviews our current state of knowledge of carnivoran ecology. It addresses all levels of biological organization and function, from genes to enzymes, organisms, populations, and ecosystems. Special attention is given to how carnivoran species interact with their prey, each other, and humans. There is an emphasis on community interactions and their importance in carnivoran evolution, showing how evolutionary constraints (morphological, physiological, and behavioral) structure communities today. The book's approach is strongly comparative, contrasting herbivores with carnivores, predators with scavengers, and cats with dogs. Carnivorans play important roles in many high-profile conservation cases, either as species of concern or agents of endangerment, and their importance is demonstrated in both contexts. Carnivoran Ecology is an accessible advanced textbook aimed principally at senior undergraduate and graduate students taking courses in carnivore ecology, as well as a broad audience of professional academics (especially carnivore and mammalian biologists), researchers, and practitioners working in both governmental and non-governmental organizations. A significant secondary market will exist amongst the large amateur naturalist community including those wishing to explore the ecological and evolutionary links between domestic carnivorans (dogs, cats, ferrets etc.) and their wild counterparts.

Enclosed Experimental Ecosystems and Scale by John E. Petersen,Victor S. Kennedy,William C. Dennison,W. Michael Kemp Pdf

Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating information among natural ecosystems that differ in scale. Enclosed Experimental Ecosystems and Scale: Tools for Understanding and Managing Coastal Ecosystems provides scientists, managers, and policy makers with an introduction to what has been termed the "problem of scale", and presents information that will allow for improved design and interpretation of enclosed experimental aquatic ecosystems. The book integrates the results of a 10-year research project involving a multi-disciplinary team of scientists and students to explore scale-related questions in a variety of coastal habitats. Anticipating use as a reference, the book has been designed so that individual sections and individual pages can function as stand alone units.
