Aménagement forestier écosystémique : Approche d'aménagement qui vise à maintenir des écosystèmes sains et résilients en misant sur une diminution des écarts entre les paysages naturels et ceux qui sont aménagés afin d'assurer, à long terme, le maintien des multiples fonctions de l'écosystème et, par conséquent, de conserver les bénéfices sociaux et économique que l'on en retire. Voilà la définition de l’aménagement forestier écosystémique proposée dans cet ouvrage qui offre une synthèse des principaux concepts écologiques qui appuient cette approche. Il présente une revue des grands régimes de perturbations qui façonnent la dynamique naturelle de la forêt boréale et des exemples provenant de différentes régions du centre et de l’est du Canada. Plusieurs projets de mise en œuvre de stratégies d’aménagement écosystémique illustrent des enjeux de la foresterie actuelle et les solutions que cette nouvelle approche peut apporter. En somme, la dynamique forestière dans son ensemble peut servir de guide à l’aménagement forestier. Une planification des interventions inspirée de la forêt facilitera la conciliation entre la récolte ligneuse et les intérêts des autres utilisateurs de la forêt.
A Bird Man in Antarctica
The year he graduated from college, twenty-two-year-old Noah Strycker was dropped by helicopter in a remote Antarctic field camp with two other bird scientists and a three-month supply of frozen food. His subjects: more than a quarter-million penguins.
The Adélie Penguins who call Antarctica home have been the subject of long-term studies—scientists may know more about how these penguins will adjust to climate change than about any other creature in the world.
With wit, curiosity, and a deep passion for his subject, Strycker weaves a captivating tale of penguins and their researchers on the coldest, driest, highest, and windiest continent on Earth. He recounts the reality of life in the Antarctic—thousand-year-old penguin mummies, hurricane-force blizzards, and day-to-day existence in below freezing temperatures—and delves deep into a world of science, obsession, and birds.
“Noah Strycker is going places, and he is taking us along for the ride. There is something fundamentally sunny about Among Penguins. This book will be a fan favorite for years to come.”—Ted Floyd, Editor, Birding
“Cape Crozier, against the largest ice shelf on Earth, in the shadow of an extinct volcano, and at the doorstep of the least human-affected stretch of ocean remaining on the planet, is one of Earth’s power spots. It’s refreshing to get Noah Strycker’s impressions of this place through his day-to-day experiences; he definitely had all his senses tested.” —David Ainley, author of The Adélie Penguin: Bellwether of Climate Change
The Conservation Status of United States Species
This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world?
This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species.
The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
A Quaternary and Recent Faunal Adventure
With its temperate climate and variety of habitats, Michigan supports a diverse array of animals and plants, including fifty-four species of amphibians and reptiles. The dispersal and biology of the Michigan herpetofauna—amphibians and reptiles—is even more unique because Michigan consists of two peninsulas that project into large freshwater seas and also because it was completely covered by a massive ice sheet a relatively short time ago. In The Amphibians and Reptiles of Michigan: A Quaternary and Recent Faunal Adventure, author J. Alan Holman explores the state’s amphibians and reptiles in detail and with many helpful illustrations, making this the only volume of its kind available. Holman uniquely bridges the gap between neo- and paleoherpetology and shows that Michigan’s modern herpetofaunas reflect Pleistocene (ice age) and Holocene (warm period after the ice age) events, as the entire modern population was forced to re-invade the state after the last withdrawal of ice. In Part 1, Holman discusses Michigan as an amphibian and reptile habitat, including a geological, climatic, and vegetational history. Part 2 presents recent species accounts, covering all fifty-four species of amphibians and reptiles, along with their general distribution, Michigan distribution (with range maps), geographic variation, habitat and habits, reproduction and growth, diet, predation and defense, interaction with humans, behavioral characteristics, population health, and general remarks. In Part 3, Holman examines the Michigan herpetofauna in Quaternary and recent historical times and the species accounts include Pleistocene, Holocene, and archaeological records. Color photographs of major herpetological habitats in Michigan are provided and color photographs of all modern species are included. Black-and-white illustrations depict both modern and ancient speicies. Herpetologists, paleontologists, zoologists, ecologists, and general biologists, as well as anyone who loves salamanders, frogs, turtles, and snakes will appreciate the comprehensive research presented in The Amphibians and Reptiles of Michigan.
Reflections on Redecorating Nature
What is it really like to be a dog? Do animals experience emotions like pleasure, joy, and grief? Marc Bekoff's work draws world-wide attention for its originality and its probing into what animals think about and know as well as what they feel, what physical and mental skills they use to live successfully within their social community. Bekoff's work, whether addressed to scientists or the general public, demonstrates that investigations into animal thought, emotions, self-awareness, behavioral ecology, and conservation biology can be compassionate as well as scientifically rigorous.In Animal Passions and Beastly Virtues, Bekoff brings together essays on his own ground-breaking research and on what scientists know about the remarkable range and flexibility of animal behavior. His fascinating and often amusing observations of dogs, wolves, coyotes, prairie dogs, elephants, and other animals playing, leaving and detecting scent-marks ("yellow snow"), solving problems, and forming friendships challenge the idea that science and the ethical treatment of animals are incompatible.
Narrating across Species Lines
An Ethical Reader in a Posthuman World
Although Cultural Studies has directed sustained attacks against sexism and racism, the question of the animal has lagged behind developments in broader society with regard to animal suffering in factory farming, product testing, and laboratory experimentation, as well in zoos, rodeos, circuses, and public aquariums. The contributors to Animal Subjects are scholars and writers from diverse perspectives whose work calls into question the boundaries that divide the animal kingdom from humanity, focusing on the medical, biological, cultural, philosophical, and ethical concerns between non-human animals and ourselves. The first of its kind to feature the work of Canadian scholars and writers in this emergent field, this collection aims to include the non-human-animal question as part of the ethical purview of Cultural Studies and to explore the question in interdisciplinary terms.
As the most populous province in Canada, Ontario is a microcosm of the animal welfare issues which beset Western civilization. The authors of this book, chairman and vice-chairman, respectively, of the Ontario Society for the Prevention of Cruelty to Animals, find themselves constantly being made aware of the atrocities committed in the Society’s jurisdiction.
They have been, in turn, puzzled, exasperated and horrified at humanity’s cruelty to our fellow sentient beings. The issues discussed in this book are the most contentious in animal welfare disputes — animal experimentation, fur-farming and trapping, the use of animals for human entertainment and the conditions under which animals are raised for human consumption. They are complex issues and should be thought about fairly and seriously.
The authors, standing squarely on the side of the animals, suggest “community” and “belonging” as concepts through which to understand our relationships to other species. They ground their ideas in Wordsworth’s “primal sympathy” and Jung’s “unconscious identity” with the animal realm. The philosophy developed in this book embraces common sense and compromise as the surest paths to the goal of animal welfare. It requires respect and consideration for other species while acknowledging our primary obligations to our fellow humans.
A World View through History
Drawing on the latest research in archaeozoology, archaeology, and molecular biology, Animals as Domesticates traces the history of the domestication of animals around the world. From the llamas of South America and the turkeys of North America, to the cattle of India and the Australian dingo, this fascinating book explores the history of the complex relationships between humans and their domestic animals. With expert insight into the biological and cultural processes of domestication, Clutton-Brock suggests how the human instinct for nurturing may have transformed relationships between predator and prey, and she explains how animals have become companions, livestock, and laborers. The changing face of domestication is traced from the spread of the earliest livestock around the Neolithic Old World through ancient Egypt, the Greek and Roman empires, South East Asia, and up to the modern industrial age.
The Past and Present of Commensal Animals
In this fascinating book, Terry O’Connor explores a distinction that is deeply ingrained in much of the language that we use in zoology, human-animal studies, and archaeology—the difference between wild and domestic. For thousands of years, humans have categorized animals in simple terms, often according to the degree of control that we have over them, and have tended to see the long story of human-animal relations as one of increasing control and management for human benefit. And yet, around the world, species have adapted to our homes, our towns, and our artificial landscapes, finding ways to gain benefit from our activities and so becoming an important part of our everyday lives. These commensal animals remind us that other species are not passive elements in the world around us but intelligent and adaptable creatures. Animals as Neighbors shows how a blend of adaptation and opportunism has enabled many species to benefit from our often destructive footprint on the world. O’Connor investigates the history of this relationship, working back through archaeological records. By requiring us to take a multifaceted view of human-animal relations, commensal animals encourage a more nuanced understanding of those relations, both today and throughout the prehistory of our species.
