The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today. "One of the best scientific books published in the last ten years."—Ottowa Journal "A valuable new synthesis of facts and ideas about climate, geography, and life during the past 20,000 years. More important, the book conveys an intimate appreciation of the rich variety of nature through time."—S. David Webb,Science

Mount Mitchell And The Black Mountains

Each year, thousands of tourists visit Mount Mitchell, the most prominent feature of North Carolina's Black Mountain range and the highest peak in the eastern United States. From Native Americans and early explorers to land speculators and conservationists, people have long been drawn to this rugged region. Timothy Silver explores the long and complicated history of the Black Mountains, drawing on both the historical record and his experience as a backpacker and fly fisherman. He chronicles the geological and environmental forces that created this intriguing landscape, then traces its history of environmental change and human intervention from the days of Indian-European contact to today. Among the many tales Silver recounts is that of Elisha Mitchell, the renowned geologist and University of North Carolina professor for whom Mount Mitchell is named, who fell to his death there in 1857. But nature's stories--of forest fires, chestnut blight, competition among plants and animals, insect invasions, and, most recently, airborne toxins and acid rain--are also part of Silver's narrative, making it the first history of the Appalachians in which the natural world gets equal time with human history. It is only by understanding the dynamic between these two forces, Silver says, that we can begin to protect the Black Mountains for future generations.

Soil contamination...public lands...surface and groundwater pollution...coastal erosion...global warming. Have we reached the limits of this planet's ability to provide for us? If so, what can we do about it? These vital questions are addressed by Jill Schneiderman in The Earth Around Us, a unique collection of thirty-one essays by a diverse array of today's foremost scientist-writers. Sharing an ability to communicate science in a clear and engaging fashion, the contributors explore Earth's history and processes--especially in relation to today's environmental issues--and show how we, as members of a global community, can help maintain a livable planet. The narratives in this collection are organized into seven parts that describe: - Earth's time and history and the place of people in it - Views of nature and the ethics behind our conduct on Earth - Resources for the twenty-first century, such as public lands, healthy forests and soils, clean ground and surface waters, and fluctuating coastlines - Ill-informed local manipulations of landscapes across the United States - Innovative solutions to environmental problems that arise from knowledge of the interactions between living things and the Earth's air, water, and soil - Natural and human-induced global scale perturbations to the earth system - Our responsibility to people and all other organisms that live on Earth Never before has such a widely experienced group of prominent earth scientists been brought together to help readers understand how earth systems function to produce our physical and biological environment. Driven by the belief that earth science is, and should be, an integral part of everyday life, The Earth Around Us empowers all of us to play a more educated and active part in the search for a sustainable future for people and other living things on our planet.

Ecologists interested in assessing landscapes and ecosystems must measure biomass, cover, and the density or frequency of various key species. Recently, sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have become fine-grained, as it has become increasingly important to accurately map and assess rare species for conservation. This book lays out the range of current methods for mapping and measuring species diversity, for field ecologists, resource managers, conservation biologist, and students, as a tool kit for future measurements of plant diversity.

Global warming and human-driven impacts from logging, natural gas drilling, mining of oil sands, and the development of hydropower increasingly threaten North America's northern forests. These forests are far from being a uniform environment; close inspection reveals that the conifers that thrive there-pines, larches, spruces, hemlocks, firs, Douglas-firs, arborvitaes, false-cypresses, junipers, and yews-support a varied and complex ecosystem. In The World of Northern Evergreens, the noted ecologist E. C. Pielou introduces the biology of the northern forests and provides a unique invitation to naturalists, ecologists, foresters, and everyone living in northern North America who wants to learn about this unique and threatened northern world and the species that make it their home. Through identification keys, descriptions, and life histories of the conifer tree species, the author emphasizes how different these plants are both biologically and evolutionarily from the hardwoods we also call "trees." Following this introduction to the essential conifers, the author's perceptive insights expand to include the interactions of conifers with other plants, fungi, mammals, birds, and amphibians. The second edition, enriched by new illustrations by the author of woodland features and creatures, updates the text to include new topics including mycorrhizal fungi, soil, woodlice, bats, and invasive insects such as the hemlock woolly adelgid. Emphasis is given to the very real human-driven impacts that threaten the species that live in and depend on the vital and complex forest ecosystem. Pielou provides us with a rich understanding of the northern forests in this work praised for its nontechnical presentation, scientific objectivity, and original illustrations.

This book tells the story of the province’s geology and the history of its living creatures. The first edition of Geology of British Columbia,, with its accessible but rigorous science, struck a chord with readers. Since it was first published, theories about plate tectonics and the geological history of British Columbia have evolved, and this new edition reflects the current thinking. This book also features updated content throughout, seven new maps, and a number of new photographs. A brand new appendix lists and describes key geological sites in British Columbia, adding a field-guide component to this informative book that will engage readers and compel them to go see these rocks for themselves.
