Plants make up 99.9 percent of the world's living matter, provide food and shelter, and control the Earth's climate. The study of plant ecology is therefore essential to understanding the biological functions and processes of the biosphere. This vibrant introductory textbook integrates important classical themes with recent ideas, models and data. The book begins with the origin of plants and their role in creating the biosphere as the context for discussing plant functional types and evolutionary patterns. The coverage continues logically through the exploration of causation with chapters, amongst others, on resources, stress, competition, predation, and mutualism. The book concludes with a chapter on conservation, addressing the concern that as many as one-third of all plant species are at risk of extinction. Each chapter is enriched with striking and unusual examples of plants (e.g., stone plants, carnivorous plants) and plant habitats (e.g., isolated tropical tepui, arctic cliffs). Paul Keddy writes in a lively and thought-provoking style which will appeal to students at all levels.
Presenting a global and interdisciplinary approach to plant ecology, this much-awaited new edition of the book Plants and Vegetation integrates classical themes with the latest ideas, models, and data. Keddy draws on extensive teaching experience to bring the field to life, guiding students through essential concepts with numerous real-world examples and full-colour illustrations throughout. The chapters begin by presenting the wider picture of the origin of plants and their impact on the Earth, before exploring the search for global patterns in plants and vegetation. Chapters on resources, stress, competition, herbivory, and mutualism explore causation, and a concluding chapter on conservation addresses the concern that one-third of all plant species are at risk of extinction. The scope of this edition is broadened further by a new chapter on population ecology, along with extensive examples including South African deserts, the Guyana Highlands of South America, Himalayan forests and arctic alpine environments.
This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.
This book presents 12 effective methods to manage wetlands for conservation. It offers a tool box of causal factors that can be used to protect and restore wetlands to enhance biological diversity and other functions. Each causal factor is introduced, briefly explained, and then illuminated with selected examples from around the world. The book provides a prioritized shopping list of methods for protecting and restoring wetlands. The three first and most important causal factors are flooding, fertility, and natural disturbance. Then nine other causal factors are introduced, including herbivory, sedimentation, roads, invasive species, and coarse woody debris. Each causal factor is carefully linked to the scientific literature and explained using the author’s own experience. The same list of 12 causal factors applies around the world—whether you are managing a temperate zone floodplain, a tropical peatland, a freshwater marsh, or a coastal mangrove swamp. Instead of hiring an expensive team of consultants, or pouring through hundreds of scientific papers, here is one concise guide to methods that can be immediately applied to benefit any wetland. Professor Paul Keddy has spent more than 50 years studying wetlands, and writing and lecturing about the environmental factors that control them. He has published more than 150 scholarly papers, and won multiple scientific prizes. His book Wetland Ecology is widely used to teach the principles of wetland science. Causal Factors for Wetland Management: A Concise Guide has a much simpler message: how to protect and enhance wetlands. In this concise guide, he has condensed a lifetime of experience into just 12 principles. The book is aimed at all people who protect or restore wetlands: park managers, wildlife biologists, landscape architects, engineers, environmental consultants, environmental agencies, conservation authorities, and NGOs—as well as landowners and concerned citizens. Causal Factors for Wetland Management: A Concise Guide is essential reading for anyone who cares for wetlands and wild places.
Richly illustrated in colour and packed with examples from every major continent and wetland type, this third edition has been completely rewritten to provide undergraduates with a thoroughly accessible introduction to the basic principles. It divides the world's wetlands into six principal types and presents six major causal environmental factors, arranged by importance and illustrated with clear examples, making it easy for instructors to plan tailored lectures and field trips and avoid overwhelming students with unnecessary detail. It retains its rigor for more advanced students with sections on research methods and experiments, and over a thousand classic and contemporary references. Each chapter ends with questions that review the content covered and encourage further investigation. With expanded sections on topical issues such as sea level rise, eutrophication, facilitation and the latest approaches to restoration and conservation, the new edition of this prize-winning textbook is a vital resource for wetland ecology courses.
#1 NATIONAL BESTSELLER A shocking exposé of the deadliest killing spree in Canadian history, and how police tragically failed its victims and survivors. As news broke of a killer rampaging across the tiny community of Portapique, Nova Scotia, late on April 18, 2020, details were oddly hard to come by. Who was the killer? Why was he not apprehended? What were police doing? How many were dead? And why was the gunman still on the loose the next morning and killing again? The RCMP was largely silent then, and continued to obscure the actions of denturist Gabriel Wortman after an officer shot and killed him at a gas station during a chance encounter. Though retired as an investigative journalist and author, Paul Palango spent much of his career reporting on Canada’s troubled national police force. Watching the RCMP stumble through the Portapique massacre, only a few hours from his Nova Scotia home, Palango knew the story behind the headlines was more complicated and damning than anyone was willing to admit. With the COVID-19 lockdown sealing off the Maritimes, no journalist in the province knew the RCMP better than Palango did. Within a month, he was back in print and on the radio, peeling away the layers of this murderous episode as only he could, and unearthing the collision of failure and malfeasance that cost a quiet community 22 innocent lives.

Born in Halifax, Nova Scotia, Paul Campbell has lived on three continents, sailed several oceans, and had many unique life experiences, most of which included his family. Paul was an athlete from a young age and eventually became a professional. His lifelong dream of making the NHL came to a horrific halt after a terrible car accident almost ended Paul's life and took the life of his good friend. After coming out of a coma, Paul started a new journey, which began in a wheelchair. He went on to earn two degrees from the University of New Brunswick. Today Paul teaches, coaches, changes lives, is a ski instructor, and a guest lecturer. While Paul never played major league hockey, he received a higher calling: to his own NHL (National Helpers League). Paul told people he would make the NHL, and even though his NHL is very different, it is even more important in the global scheme of things.
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.

Plant evolutionary ecology is a rapidly growing discipline which emphasizes that populations evolve and adapt not in isolation, but in relation to other species and abiotic environmental features such as climate. By combining approaches from the traditional evolutionary and ecological fields of study, evolutionary ecology is connected to branches of population biology, genetics, botany, conservation, and to other fields of applied science, primarily through shared concepts and techniques. However, other books regarding evolutionary ecology typically focus on animals, creating a substantial need for a synthesis of the scholarly literature with an emphasis on plants. Approaches to Plant Evolutionary Ecology is the first book to specifically explore the evolutionary biology of plant populations. Renowned plant ecologist G. P. Cheplick summarizes and synthesizes much of the primary literature regarding evolutionary perspective. The book also provides summaries of both traditional (common gardens, reciprocal transplants) and modern (molecular genetic) approaches used to address questions about plant adaptation to a diverse group of abiotic and biotic factors. Cheplick provides a rigorously written introduction to the rapidly growing field of plant evolutionary ecology that will appeal to undergraduate and graduate students with an interest in ecology and evolution, as well as educators who are teaching courses on related topics. -- from back cover.
The Smithsonian Institution has grown and prospered since the first edition of this book appeared in 1970, and Paul Oehser's revised edition is badly needed. New and expanded structures (the Air and Space Museum, the Hirshhorn, the National Museum of American Art, the National Portrait Gallery) and new undertakings (Smithsonian magazine, the Handbook of North American Indians series, the Woodrow Wilson Center, and prestigious symposia) richly serve the original purpose James Smithson envisioned in his will: " To found at Washington, under the name of the Smithsonian Institution, an establishment for the increase and diffusion of knowledge among men." The heart of Oehser's original work has been left intact in this second edition. His is the only survey that combines the dramatic story of the Smithsonian's influence and expansion with the behind-the-scenes details of daily operations, structure, and administrative problems. The book has been updated to include all important developments of the last thirteen years, as well as to describe current plans for future expansion and program additions. The whole picture leads one to the conclusion that the world's largest museum complex, housing over seventy million objects, has succeeded—despite its air of old-fashioned traditionalism—in reflecting the adventure of the American experience and the insatiable curiosity and dynamics of the American spirit.

This 100,000-word monograph summarizes the distribution, abundance and breeding biology of the 183 species of wetland-adapted birds reliably reported from South Dakota, Nebraska and Kansas through 2011. These include 91 species known to breed or have historically bred in the region, 51 species that migrate through the region but are not yet known to breed or have bred there, and 41 species that are extremely rare, probably extinct, or for which evidence as to their current occurrence is questionable. Brief summaries of the breeding biology of all the regionally nesting species are provided, and information for all species is summarized as to seasonal migrations, habitats, and (in most cases) population status. There is an introductory account of the topography, climate and vegetation of the region insofar as these environmental factors influence wetland birds, six regional maps, and more than 500 references.

This book covers two aspects of the career of D Allan Bromley: the science policy aspect and the scientific aspect.In the first half of the book, contributions from Governor John Sununu, former White House Chief of Staff under President George H W Bush; Neal Lane, former Science Adviser to President William Clinton; John Marburger III, Science Adviser to President George W Bush; and Mary Good, former Undersecretary of Commerce, highlight the role of Bromley as Science Adviser to President George H W Bush and a maker of science policy in the second part of the 20th Century. This part is of interest to science policy scholars, historians, and young persons wishing to start a career in science policy.In the second half of the book, articles by directors of laboratories and leading scientists discuss future programs in all areas of nuclear physics ? low-energy, medium-energy and high-energy ? to which Bromley greatly contributed, in the USA, Europe and Japan. This part of the book is of interest to all researchers in the field of nuclear physics, as it provides a comprehensive but succinct overview of the field and indicates directions for future research in the first part of the 21st century.
This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecol ogy addresses the relationships among spatial patterns, temporal pat terns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an import ant variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as needed for comprehension of system processes and the mosaic included may be very heteroge neous. Intellectual utility and applicability of results are valued equally. The International Association for Landscape Ecology sponsors this series of studies in order to introduce and disseminate some of the new knowledge that is being produced by this exciting new environmental science. Gray Merriam Ottawa, Canada Preface In Europe, during the seventies, landscape ecology emerged as a fusion of the spatial approach of geographers and the functional approach of ecologists. The latter focused on ecosystem functioning, regarding eco systems as homogeneous, almost abstract units in space, with input and output of energy and matter to and from the undefined surroundings.
