Book Synopsis Beavers: Boreal Ecosystem Engineers by : Carol A. Johnston
Download or read book Beavers: Boreal Ecosystem Engineers written by Carol A. Johnston and published by Springer. This book was released on 2017-08-28 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of ecosystem science and landscape ecology, this book integrates Dr. Carol Johnston's research on beaver ecosystem alteration at Voyageurs National Park. The findings about the vegetation, soils, and chemistry of beaver impoundments synthesized in the text provide a cohesive reference useful to wetland scientists, ecosystems and landscape ecologysts, wildlife managers, and students. The beaver, Castor canadensis, is an ecosystem engineer unequaled in its capacity to alter landscapes through browsing and dam building, whose population recovery has re-established environmental conditions that probably existed for millenia prior to its near extirpation by trapping in the 1800s and 1900s. Beavers continue to regain much of their natural range throughout North America, changing stream and forest ecosystems in ways that may be lauded or vilified. Interest in beavers by ecologists remains keen as new evidence emerges about the ecological, hydrological, and biogeochemical effects of beaver browsing and construction. There is a critical need for ecologists and land managers to understand the potential magnitude, persistence, and ecosystem services of beaver landscape transformation. The 88-year record of beaver landscape occupation and alteration documented by Dr. Carol Johnston and colleagues from aerial photography and field work provides a unique resource toward understanding the ecosystem effects and sustainability of beaver activity.
Book Synopsis Linking Species & Ecosystems by : Clive G. Jones
Download or read book Linking Species & Ecosystems written by Clive G. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: I was asked to introduce this volume by examining "why a knowledge of ecosys tem functioning can contribute to understanding species activities, dynamics, and assemblages." I have found it surprisingly difficult to address this topic. On the one hand, the answer is very simple and general: because all species live in ecosystems, they are part of and dependent on ecosystem processes. It is impossible to understand the abundance and distribution of populations and the species diversity and composition of communities without a knowledge of their abiotic and biotic environments and of the fluxes of energy and mat ter through the ecosystems of which they are a part. But everyone knows this. It is what ecology is all about (e.g., Likens, 1992). It is why the discipline has retained its integrity and thrived, despite a sometimes distressing degree of bickering and chauvinism among its various subdisciplines: physiological, be havioral, population, community, and ecosystem ecology.

Book Synopsis Landscape Ecology in Theory and Practice by : Monica G. Turner
Download or read book Landscape Ecology in Theory and Practice written by Monica G. Turner and published by Springer. This book was released on 2015-10-29 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work provides in-depth analysis of the origins of landscape ecology and its close alignment with the understanding of scale, the causes of landscape pattern, and the interactions of spatial pattern with a variety of ecological processes. The text covers the quantitative approaches that are applied widely in landscape studies, with emphasis on their appropriate use and interpretation. The field of landscape ecology has grown rapidly during this period, its concepts and methods have matured, and the published literature has increased exponentially. Landscape research has enhanced understanding of the causes and consequences of spatial heterogeneity and how these vary with scale, and they have influenced the management of natural and human-dominated landscapes. Landscape ecology is now considered mainstream, and the approaches are widely used in many branches of ecology and are applied not only in terrestrial settings but also in aquatic and marine systems. In response to these rapid developments, an updated edition of Landscape Ecology in Theory and Practice provides a synthetic overview of landscape ecology, including its development, the methods and techniques that are employed, the major questions addressed, and the insights that have been gained.”
Book Synopsis The Eurasian Beaver Handbook by : Roisin Campbell-Palmer
Download or read book The Eurasian Beaver Handbook written by Roisin Campbell-Palmer and published by Pelagic Publishing Ltd. This book was released on 2016-08-15 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.
Book Synopsis Invertebrates in Freshwater Wetlands by : Darold Batzer
Download or read book Invertebrates in Freshwater Wetlands written by Darold Batzer and published by Springer. This book was released on 2016-02-05 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.
Download or read book Ecosystem Engineers written by and published by Academic Press. This book was released on 2011-09-21 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book entirely devoted to this topic, Ecosystem Engineers begins with the history of the concept, presenting opposing definitions of ecosystem engineeing. These varied definitions advance the debate and move past trivial difficulties to crystallize key issues such as the value of process-based vs. outcome-based. Authors include case studies spanning a wide spectrum of species and habitats, including above and below-ground, aquatic and terrestrial, and extant and paleontological examples. These studies enable readers to understand how the categorization of species as ecosystem engineers allows scientists to forge new explanatory generalizations. Key for all ecologists and environmentalists, this book ultimately illustrates how to inform and manage natural resources. The only consolidated treatment available Provides definitions, case studies, and examples of ecological models Discusses how ecosystem engineering can inform and improve the management of natural resources Includes contributions from Clive Jones, the leading figure in the development of the ecosystem engineer concept, and many other eminent ecologists, such as Alan Hastings
Book Synopsis Ecological Understanding by : Steward T.A. Pickett
Download or read book Ecological Understanding written by Steward T.A. Pickett and published by Elsevier. This book was released on 2013-10-22 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology is an historical science in which theories can be as difficult to test as they are to devise. This volume, intended for ecologists and evolutionary biologists, reviews ecological theories, and how they are generated, evaluated, and categorized. Synthesizing a vast and sometimes labyrinthine literature, this book is a useful entry into the scientific philosophy of ecology and natural history. The need for integration of the contributions to theory made by different disciplines is a central theme of this book. The authors demonstrate that only through such integration will advances in ecological theory be possible. Ecologists, evolutionary biologists, and other serious students of natural history will want this book.
Book Synopsis Niche Construction by : F. John Odling-Smee
Download or read book Niche Construction written by F. John Odling-Smee and published by Princeton University Press. This book was released on 2013-02-15 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seemingly innocent observation that the activities of organisms bring about changes in environments is so obvious that it seems an unlikely focus for a new line of thinking about evolution. Yet niche construction--as this process of organism-driven environmental modification is known--has hidden complexities. By transforming biotic and abiotic sources of natural selection in external environments, niche construction generates feedback in evolution on a scale hitherto underestimated--and in a manner that transforms the evolutionary dynamic. It also plays a critical role in ecology, supporting ecosystem engineering and influencing the flow of energy and nutrients through ecosystems. Despite this, niche construction has been given short shrift in theoretical biology, in part because it cannot be fully understood within the framework of standard evolutionary theory. Wedding evolution and ecology, this book extends evolutionary theory by formally including niche construction and ecological inheritance as additional evolutionary processes. The authors support their historic move with empirical data, theoretical population genetics, and conceptual models. They also describe new research methods capable of testing the theory. They demonstrate how their theory can resolve long-standing problems in ecology, particularly by advancing the sorely needed synthesis of ecology and evolution, and how it offers an evolutionary basis for the human sciences. Already hailed as a pioneering work by some of the world's most influential biologists, this is a rare, potentially field-changing contribution to the biological sciences.

Book Synopsis Essentials of Landscape Ecology by : Kimberly A. With
Download or read book Essentials of Landscape Ecology written by Kimberly A. With and published by Oxford University Press. This book was released on 2019-07-01 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activity during the Anthropocene has transformed landscapes worldwide on a scale that rivals or exceeds even the largest of natural forces. Landscape ecology has emerged as a science to investigate the interactions between natural and anthropogenic landscapes and ecological processes across a wide range of scales and systems: from the effects of habitat or resource distributions on the individual movements, gene flow, and population dynamics of plants and animals; to the human alteration of landscapes affecting the structure of biological communities and the functioning of entire ecosystems; to the sustainable management of natural resources and the ecosystem goods and services upon which society depends. This novel and comprehensive text presents the principles, theory, methods, and applications of landscape ecology in an engaging and accessible format that is supplemented by numerous examples and case studies from a variety of systems, including freshwater and marine "scapes".
Book Synopsis Landscape Heterogeneity and Disturbance by : Monica G. Turner
Download or read book Landscape Heterogeneity and Disturbance written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape pattern is generated by a variety of processes, including disturbances. In turn, the heterogeneity of the landscape may enhance or retard the spread of disturbance. The complex relationship between landscape pattern and disturbance is the subject of this book. It is designed to present an illustrative analysis of the topic, presenting the perspectives of several different disciplines. The book includes conceptual considerations, empirical studies, and management examples. Important features include: hypotheses about the spread of disturbance and the effects of scale changes in landscape studies; the multidisciplinary approach; and the explicit focus on the landscape level. The intended audience comprises graduate students, academics, and professionals interested in landscape ecology. The reader will receive a state-of-the-art treatment of a current topic in landscape ecology.

Book Synopsis Biodiversity in a Rapidly Changing World by : Benjamin Baiser
Download or read book Biodiversity in a Rapidly Changing World written by Benjamin Baiser and published by . This book was released on 2009 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions and extinctions have reorganized the earth's biota and altered biodiversity across all spatial scales. At the local scale, invasions have outpaced extinctions for many taxonomic groups. This suggests that food webs, which represent feeding interactions at the local scale, may be increasing in species richness. Importantly, the non-random addition and deletion of species has also altered the compositional similarity between regions or locales (beta diversity). The result is that spatially distinct assemblages have become more or less similar in species composition and abundance through the processes of biotic homogenization and biotic differentiation, respectively. In this dissertation, I addressed local scale interactions by exploring the influence of food web structure on invasion success in model food webs. I also quantified patterns of change in taxonomic and functional similarity across space and time to understand the effects of invasions and extinctions on large scale spatial patterns of diversity. I used a Lotka-Volterra food web model to develop predictions about how trophic structure influences invasion success (Chapter 1). I found that successful establishment in model food webs largely depends on the trophic level of the invader, due to interactions with adjacent trophic levels. My model makes four predictions that can be tested in natural or experimental communities; 1) invasion success of top predators will increase with greater diversity in native prey items, 2) basal invasion will be controlled by the number of native consumers, 3) invasive omnivore establishment will be controlled by diversity in the lowest trophic level of potential prey items, and 4) intermediate invasion success will be controlled by the diversity of native predators. I developed two methods that measure large scale spatial patterns of biodiversity. The dendrogram-based method, which quantifies change in taxonomic similarity, (Chapter 2) introduces three metrics that each describes a different aspect of change in taxonomic similarity as depicted by a dendrogram. This method is unique in that the spatial and historical affinities of assemblages are tracked through time providing insight into how evolutionary history and spatial dynamics influence patterns of homogenization. The utility of the dendrogram-based method was exemplified by the case study of the Hawaiian Island avifauna, which showed that between-island similarity in the historical time period follows the geologic history of the islands and the influence of prior extinction filters on the perceived homogenization of assemblages. The second method is a trait based method for quantifying change in functional similarity through time (Chapter 3). Simulations indicate that functional and taxonomic similarity are positively correlated as trait complementarity increases. Functional and taxonomic similarity are positively correlated for the breeding and foraging traits in bird assemblages at ten locales across the United States from 1968 to 2008. This relationship suggests a high level of trait complementarity among the breeding bird assemblages, but further empirical examples are necessary to determine the bounds of trait complementarity in real assemblages. The impact of humans on biodiversity is complex in that it involves measuring both taxonomic and functional attributes of communities across different spatial scales. Methods for elucidating anthropogenic impacts on biodiversity and ecosystem function must take this into consideration when assessing impacts and developing conservation planning.
