Download or read book Witness Tree written by Lynda Mapes and published by Bloomsbury Publishing USA. This book was released on 2017-04-11 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.
Download or read book New England Forests Through Time written by David R. Foster and published by . This book was released on 2000 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past three hundred years New England's landscape has been transformed. The forests were cleared; the land was farmed intensively through the mid-nineteenth century and then was allowed to reforest naturally as agriculture shifted west. Today, in many ways the region is more natural than at any time since the American Revolution. This fascinating natural history is essential background for anyone interested in New England's ecology, wildlife, or landscape. In New England Forests through Time these historical and environmental lessons are told through the world-renowned dioramas in Harvard's Fisher Museum. These remarkable models have introduced New England's landscape to countless visitors and have appeared in many ecology, forestry, and natural history texts. This first book based on the dioramas conveys the phenomenal history of the land, the beauty of the models, and new insights into nature.

Download or read book Hemlock written by Anthony D'Amato and published by Yale University Press. This book was released on 2014-04-29 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: An appreciation of the beautiful, iconic, and endangered Eastern Hemlock and what it means to nature and society The Eastern Hemlock, massive and majestic, has played a unique role in structuring northeastern forest environments, from Nova Scotia to Wisconsin and through the Appalachian Mountains to North Carolina, Tennessee, and Alabama. A “foundation species” influencing all the species in the ecosystem surrounding it, this iconic North American tree has long inspired poets and artists as well as naturalists and scientists. Five thousand years ago, the hemlock collapsed as a result of abrupt global climate change. Now this iconic tree faces extinction once again because of an invasive insect, the hemlock woolly adelgid. Drawing from a century of studies at Harvard University’s Harvard Forest, one of the most well-regarded long-term ecological research programs in North America, the authors explore what hemlock’s modern decline can tell us about the challenges facing nature and society in an era of habitat changes and fragmentation, as well as global change.
Download or read book The Atlas of Economic Complexity written by Ricardo Hausmann and published by MIT Press. This book was released on 2014-01-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maps capture data expressing the economic complexity of countries from Albania to Zimbabwe, offering current economic measures and as well as a guide to achieving prosperity Why do some countries grow and others do not? The authors of The Atlas of Economic Complexity offer readers an explanation based on "Economic Complexity," a measure of a society's productive knowledge. Prosperous societies are those that have the knowledge to make a larger variety of more complex products. The Atlas of Economic Complexity attempts to measure the amount of productive knowledge countries hold and how they can move to accumulate more of it by making more complex products. Through the graphical representation of the "Product Space," the authors are able to identify each country's "adjacent possible," or potential new products, making it easier to find paths to economic diversification and growth. In addition, they argue that a country's economic complexity and its position in the product space are better predictors of economic growth than many other well-known development indicators, including measures of competitiveness, governance, finance, and schooling. Using innovative visualizations, the book locates each country in the product space, provides complexity and growth potential rankings for 128 countries, and offers individual country pages with detailed information about a country's current capabilities and its diversification options. The maps and visualizations included in the Atlas can be used to find more viable paths to greater productive knowledge and prosperity.
Download or read book Forest Rites written by Peter Sahlins and published by Cambridge, Mass. : Harvard University Press. This book was released on 1994 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 1829, strange reports surfaced from the Ari ge department in the French Pyrenees, describing male peasants, bizarrely dressed in women's clothes, gathering in the forests at night to chase away state guards and charcoal-makers. This was the raucous War of the Demoiselles, a protest against the national French Forest Code of 1827, which restricted peasants' rights to use state and private forests. Peter Sahlins unravels the fascinating story of this celebrated popular uprising, and in his telling captures the cultural, historical, and political currents that swept the countryside during France's July 1830 Revolution. Sahlins explains how and why the Ari ge peasants drew on the practices and rituals of folk culture, as well as on a revolutionary tradition, to defend their inherited rights to the forest. To explore these rights and their expression, he delves into the history of forest management, of peasant conflicts with the state, and of popular culture--particularly the disputed history of Carnival and of local rituals of justice. Sahlins also sheds new light on the French revolutionary tradition and the "Three Glorious Days" of July 1830. The drama and symbolism of the War of the Demoiselles have inspired nearly a dozen plays, novels, films, and even a comic book. Using the concepts of anthropology and cultural studies as transport, Sahlins moves from this rich event to the wider worlds of peasant society in France. Focusing on the years from 1829 to 1832 but drawing on sources since the sixteenth century, his book should captivate social, cultural, and political historians of both early modern and modern Europe.

Available in PDF, EPUB and Kindle. Book excerpt: "Originally published in the June 11, 1984, New Yorker, this lengthy essay is a sharp-edged inquiry into the generational institutions of our national life. George Trow tells the story of upstate New York's Black Rock Forest - a 3,800-acre site overlooking the Hudson River - through the lives of the men who were connected to it and through the larger histories of Harvard University, U.S. conservation policies, and physics and biology. His story is ultimately a symbolic tale that bears upon some of the most significant institutions, professions, and legacies in contemporary American life"--Book jacket.

Download or read book The Last Negroes at Harvard written by Kent Garrett and published by Mariner Books. This book was released on 2020 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The untold story of the Harvard class of '63, whose Black students fought to create their own identities on the cusp between integration and affirmative action. In the fall of 1959, Harvard recruited an unprecedented eighteen "Negro" boys as an early form of affirmative action. Four years later they would graduate as African Americans. Some fifty years later, one of these trailblazing Harvard grads, Kent Garrett, would begin to reconnect with his classmates and explore their vastly different backgrounds, lives, and what their time at Harvard meant. Garrett and his partner Jeanne Ellsworth recount how these eighteen youths broke new ground, with ramifications that extended far past the iconic Yard. By the time they were seniors, they would have demonstrated against national injustice and grappled with the racism of academia, had dinner with Malcolm X and fought alongside their African national classmates for the right to form a Black students' organization. Part memoir, part group portrait, and part narrative history of the intersection between the civil rights movement and higher education, this is the remarkable story of brilliant, singular boys whose identities were changed at and by Harvard, and who, in turn, changed Harvard.

Download or read book Why Forests Why Now written by Frances Seymour and published by Brookings Institution Press. This book was released on 2016-12-27 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.

Download or read book Forest Plans of North America written by Jacek P. Siry and published by Academic Press. This book was released on 2015-03-13 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. - Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America - Illustrates plans that have specifically been developed by landowners and land managers - Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans - Each chapter contains color photographs, maps, and figures
Download or read book The Ants written by Bert Hölldobler and published by Harvard University Press. This book was released on 1990 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Arctic to South Africa - one finds them everywhere: Ants. Making up nearly 15% of the entire terrestrial animal biomass, ants are impressive not only in quantitative terms, they also fascinate by their highly organized and complex social system. Their caste system, the division of labor, the origin of altruistic behavior and the complex forms of chemical communication makes them the most interesting group of social organisms and the main subject for sociobiologists. Not least is their ecological importance: Ants are the premier soil turners, channelers of energy and dominatrices of the insect fauna. TOC:The importance of ants.- Classification and origins.- The colony life cycle.- Altruism and the origin of the worker caste.- Colony odor and kin recognition.- Queen numbers and domination.- Communication.- Caste and division of labor.- Social homeostasis and flexibility.- Foraging and territorial strategies.- The organization of species communities.- Symbioses among ant species.- Symbioses with other animals.- Interaction with plants.- The specialized predators.- The army ants.- The fungus growers.- The harvesters.- The weaver ants.- Collecting and culturing ants.- Glossary.- Bibliography.- Index.
Download or read book Xylem Structure and the Ascent of Sap written by Melvin T. Tyree and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book was the first to provide an integrated description of sap ascension from an anatomical and functional point of view. The second edition opens with the three-dimensional aspects of wood anatomy. The cohesion-tension theory and new evidence are introduced in response to recent controversies over the mechanism of sap ascent in plants. The physiology, anatomy and biophysics of xylem dysfunction are discussed and new insights into hydraulic architecture are reviewed with special emphasis on physiological limits on maximum transpiration and how hydraulic architecture limits gas exchange, carbon gain and growth of plants. The text concludes with a description of xylem failure and pathology. The book highlights fascinating areas of current research with the aim to stimulate more work in the future.
