Available in PDF, EPUB and Kindle. Book excerpt: The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from the top by predator exclosures, they have traced the plant-herbivore relationships and the predator-prey relationships in this ecosystem to try to answer the question of what drives small mammal population cycles. This study is unique in being large scale and experimental on a relatively simple ecosystem, with the overall goal of defining what determines community structure in the boreal forest. Ecosystem Dynamics of the Boreal Forest: The Kluane Project summarizes these findings, weaving new discoveries of the role of herbivores-turned-predators, compensatory plant growth, and predators-eating-predators with an ecological story rich in details and clear in its findings of a community where predation plays a key role in determining the fate of individuals and populations. The study of the Kluane boreal forest raises key questions about the scale of conservation required for boreal forest communities and the many mammals and birds that live there.

Available in PDF, EPUB and Kindle. Book excerpt: This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems. Topics are as diverse as the students, who represent virtually every department, school and college at OSU. The environmental issue that is described in each chapter is particularly important to the author, who hopes that their story will serve as inspiration to protect Earth for all life.

Download or read book Complex Population Dynamics written by Peter Turchin and published by Princeton University Press. This book was released on 2013-02-15 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do organisms become extremely abundant one year and then seem to disappear a few years later? Why do population outbreaks in particular species happen more or less regularly in certain locations, but only irregularly (or never at all) in other locations? Complex population dynamics have fascinated biologists for decades. By bringing together mathematical models, statistical analyses, and field experiments, this book offers a comprehensive new synthesis of the theory of population oscillations. Peter Turchin first reviews the conceptual tools that ecologists use to investigate population oscillations, introducing population modeling and the statistical analysis of time series data. He then provides an in-depth discussion of several case studies--including the larch budmoth, southern pine beetle, red grouse, voles and lemmings, snowshoe hare, and ungulates--to develop a new analysis of the mechanisms that drive population oscillations in nature. Through such work, the author argues, ecologists can develop general laws of population dynamics that will help turn ecology into a truly quantitative and predictive science. Complex Population Dynamics integrates theoretical and empirical studies into a major new synthesis of current knowledge about population dynamics. It is also a pioneering work that sets the course for ecology's future as a predictive science.

Book excerpt: The definitive guide to all lagomorphs—pikas, rabbits, and hares. Numbering 92 species worldwide, members of the order Lagomorpha are familiar to people throughout the world, and yet their remarkable diversity and ecological importance are often underappreciated. In this book, Andrew T. Smith and his colleagues bring together the world’s lagomorph experts to produce the most comprehensive reference on the order ever published, featuring detailed species accounts, stunning color photos, and up-to-date range maps. Contributors highlight the key ecological roles that lagomorphs play and explain in depth how scientists around the globe are working to save vulnerable populations. Thematic introductory chapters cover a broad spectrum of information about pikas, rabbits, and hares, from evolution and systematics to diseases and conservation. Each animal account begins with the complete scientific and common names for the species, followed by a detailed description of appearance and unique morphological characteristics, including a range of standard measurements of adult specimens. Subsequent sections discuss known paleontological data concerning the species, the current state of its taxonomy, and geographic variation. Each account also includes dedicated sectioins on habitat and diet, reproduction and development, ecology, behavior, and management. The definitive work on lagomorphs, this book is an invaluable reference for naturalists, professional biologists, and students. It will also be beneficial for those conducting biodiversity surveys and conservation throughout the world.
Download or read book The Hare written by Melanie Finn and published by Two Dollar Radio. This book was released on 2021-01-26 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: * 2021 Vermont Book Award, Winner. * 2021 New England Book Awards, Finalist. * A3C Reads: March 2023 Book of the Month. "A Most Anticipated Book of 2021" —Elle, Bustle, BuzzFeed, Vulture The Hare is an affecting portrait of Rosie Monroe, of her resilience and personal transformation under the pin of the male gaze. Raised to be obedient by a stern grandmother in a blue-collar town in Massachusetts, Rosie accepts a scholarship to art school in New York City in the 1980s. One morning at a museum, she meets a worldly man twenty years her senior, with access to the upper crust of New England society. Bennett is dashing, knows that “polo” refers only to ponies, teaches her which direction to spoon soup, and tells of exotic escapades with Truman Capote and Hunter S. Thompson. Soon, Rosie is living with him on a swanky estate on Connecticut’s Gold Coast, naively in sway to his moral ambivalence. A daughter—Miranda—is born, just as his current con goes awry forcing them to abscond in the middle of the night to the untamed wilderness of northern Vermont. Almost immediately, Bennett abandons them in an uninsulated cabin without a car or cash for weeks at a time, so he can tend a teaching job that may or may not exist at an elite college. Rosie is forced to care for her young daughter alone, and to tackle the stubborn intricacies of the wood stove, snowshoe into town, hunt for wild game, and forage in the forest. As Rosie and Miranda’s life gradually begins to normalize, Bennett’s schemes turn malevolent, and Rosie must at last confront his twisted deceptions. Her actions have far-reaching and perilous consequences. An astounding new literary thriller from a celebrated author at the height of her storytelling prowess, The Hare bravely considers a woman’s inherent sense of obligation—sexual and emotional—to the male hierarchy, and deserves to be part of our conversation as we reckon with #MeToo and the Brett Kavanaugh Supreme Court confirmation hearing. Rosie Monroe emerges as an authentic, tarnished feminist heroine.
