Fifteen Thousand Years on One Square Mile
"Ceremonial time" occurs when past, present, and future can be perceived simultaneously. Experienced only rarely, usually during ritual dance, this escape from linear time is the vehicle for John Mitchell's extraordinary writing. In this, his most magical book, he traces the life of a single square mile in New England, from the last ice age through years of human history, including bear shamans, colonists, witches, local farmers, and encroaching industrial "parks."
Les changements climatiques sont une question environnementale majeure de ce siècle. Afin de comprendre et de prévoir leurs effets sur la biodiversité du Québec, des climatologues, des biologistes, des naturalistes et des gestionnaires de notre patrimoine naturel ont collaboré durant cinq années pour produire cet ouvrage.
Ils ont analysé les répartitions de près de 1 000 espèces d’animaux et de plantes et ont tenté d’anticiper les changements potentiels de ces répartitions pour la fin du xxie siècle. En utilisant des approches scientifiques parmi les plus perfectionnées ainsi que des modèles climatiques et des informations sur la biodiversité parmi les plus à jour, ils ont dressé un tableau saisissant des changements profonds qui sont anticipés sur le territoire québécois.
Les premiers chapitres présentent avec clarté le patrimoine naturel et les climats du Québec. Le lecteur est ensuite amené, à partir de résultats de modélisation publiés ici pour la première fois, à se projeter dans l’avenir pour entrevoir l’évolution du patrimoine naturel québécois. Les conséquences des recherches sur la gestion des espèces, des aires protégées et des écosystèmes sont enfin exposées.
Les biologistes, les naturalistes, les techniciens en écologie, les gestionnaires de la faune et des parcs, les ingénieurs et les techniciens forestiers, les professionnels et les militants de la conservation de la nature, les décideurs, ainsi que les étudiants et enseignants en biologie trouveront tous dans ce livre la matière à d’intenses réflexions. Les points à retenir sont résumés, des dizaines de cartes en couleur sont présentées et de multiples figures illustrent les messages importants. Un site Web présente des milliers de cartes complémentaires et permet de télécharger toutes les figures du livre.
The Changing Nature of the Maine Woods is both a fascinating introduction to the forests of Maine and a detailed but accessible narrative of the dynamism of these ecosystems. This is natural history with a long view, starting with an overview of the state's geological history, the reemergence of the forest after glacial retreat, and the surprising changes right up to European arrival. The authors create a vivid picture of Maine forests just before the impact of Euro-Americans and trace the profound transformations since settlement.
Ambitious in its geographic range, this book explores how and why Maine forests differ across the state, from the top of Mount Katahdin to the coast. Through groundbreaking research and engaging narratives, the authors assess key ecological forces such as climate change, insects and disease, nonnative organisms, natural disturbance, and changing land use to create a dramatic portrait of Maine forests--past, present, and future.
This book both synthesizes the latest scientific discoveries regarding the changing forest and relates the findings to an educated lay and academic audience.
Literary Roots of Modern Ecology in the British Nineteenth Century
In Chaos and the Microcosm, Heidi Scott integrates literary readings with contemporary ecological methods to investigate two essential and contrasting paradigms of nature that scientific ecology continues to debate: chaos and balance. Ecological literature of the Romantic and Victorian eras uses environmental chaos and the figure of the balanced microcosm as tropes essential to understanding natural patterns, and these eras were the first to reflect upon the ecological degradations of the Industrial Revolution. Chaos and the Microcosm contends that the seed of imagination that would enable a scientist to study a lake as a microcosmic world at the formal, empirical level was sown by Romantic and Victorian poets who consciously drew a sphere around their perceptions in order to make sense of spots of time and place amid the globalizing modern world. This study’s interest goes beyond likening literary tropes to scientific aesthetics; it aims to theorize the interdisciplinary history of the concepts that underlie our scientific understanding of modern nature. Paradigmatic ecological ideas like ecosystems, succession dynamics, punctuated equilibrium, and climate change are shown to have a literary foundation that preceded their status as theories in science. This book is an elevation of the prospects of ecocriticism towards fully developed interdisciplinary potentials of literary ecology.
Descending into the Myth of Deliverance River
This is John Lane’s search for the real Chattooga--for the truths that reside somewhere in the river’s rapids, along its shores, or in its travelers’ hearts. Lane balances the dark, indifferent mythical river of Deliverance against the Chattooga known to locals and to the outdoors enthusiasts who first mastered its treacherous vortices and hydraulics. Starting at its headwaters, Lane leads us down the river and through its complex history to its current status as a National Wild and Scenic River. Along the way he stops for talks with conservation activists, seventh-generation residents, locals who played parts in the movie, day visitors, and others. Lane weaves into each encounter an abundance of details drawn from his perceptive readings and viewings of Deliverance and his wide-ranging knowledge of the Chattooga watershed. At the end of his run, Lane leaves us still fully possessed by the Chattooga’s mystery, yet better informed about its place in his world and ours.
This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way.
This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists.

New Habitat for America's Mysterious Birds
Chimney Swifts, birds that nest and roost in chimneys, have been historically abundant in North America. But by the late 1980s, the number of swifts migrating to North America from the Amazon River Basin had declined. A growing number of people across North America are now constructing nesting towers and conducting Chimney Swift conservation projects in their own communities. With Chimney Swift Towers, concerned bird conservationists have a step-by-step guide to help them create more habitat for these beneficial, insect-eating birds. Chimney Swift experts Paul and Georgean Kyle give directions for building freestanding wooden towers, wooden kiosk towers, masonry towers, and other structures. Included are - design basics, - lists of materials needed, - useful diagrams and photographs, - and detailed instructions on site preparation, tower construction, installation, and maintenance. Anyone with basic woodworking or masonry skills and an interest in wildlife conservation will find this publication helpful. That includes do-it-yourselfers, homeowners involved in creating backyard habitat for wildlife, landscape and structural architects, park and wildscape managers, wildlife management area professionals, nature centers, garden centers, scout troops, and other civic organizations in search of community service projects.
