Book excerpt: Phosphorus is essential to the production of our food, and it also triggers algal blooms in lakes, rivers, and oceans when it slips through our hands. An understanding of this essential resource and how we have used and misused it over the years is crucial to the sustainability of our well-being on our planet. In this book, world authorities on phosphorus sustainability Jim Elser and Phil Haygarth explain this element's involvement in biology, human health and nutrition, food production, ecosystem function, and environmental sustainability. Phosphorus chronicles the sustainability challenges phosphorus both poses and solves in various contexts. The book begins with its discovery over 350 years ago, moving to its basic chemistry and the essential role it plays in all living things on Earth. Chapters go on to explain the rise in the usage of phosphorus in agriculture and how the increase in the mining of rock phosphate in the mid-20th century was essential for the Green Revolution. However, phosphorus emissions from human wastes and detergents triggered widespread algal blooms in the 1960s and 1970s. While such emissions have been brought under better control with wastewater treatment, diffuse emissions from farming continue to cause water quality degradation. The authors explain how these diffuse phosphorus emissions may worsen with climate change. In ten concise chapters, Elser and Haygarth offer engaging explanations of our historical use and abuse of phosphorus, including the phosphorus sustainability movement and new efforts to sustain food benefits of limited rock reserves following the phosphate rock price shock in 2007-2008. Highlighting new approaches for phosphorus, the two "Systems Innovators" turn toward the emerging set of sustainable phosphorus solutions necessary to achieve a sustainable "phosphoheaven" and avoid "phosphogeddon." The book provides an insider's take on this essential resource and why all of us need to wrestle with the wicked problems this element will cause, illuminate, or eliminate in years to come.

Download or read book Montana s Pioneer Naturalist written by George M. Dennison and published by University of Oklahoma Press. This book was released on 2016-09-21 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: A naturalist on Montana’s academic frontier, passionate conservationist Morton J. Elrod was instrumental in establishing the Department of Biology at the University of Montana, as well as Glacier National Park and the National Bison Range. In Montana’s Pioneer Naturalist, the first in-depth assessment of Elrod’s career, George M. Dennison reveals how one man helped to shape the scholarly study of nature and its institutionalization in the West at the turn of the century. Elrod moved to Missoula in 1897, just four years after the state university’s founding, and participated in virtually every aspect of university life for almost forty years. To reveal the depths of this pioneer scientist’s influence on the growth of his university, his state, and the academic fields he worked in, author George M. Dennison delves into state and university archives, including Elrod’s personal papers. Although Elrod was an active participant in bison conservation and the growth of the National Park Naturalist Service, much of his work focused on Flathead Lake, where he surveyed local life forms and initiated the university’s biological station—one of the first of its kind in the United States. Yet at heart Elrod was an educator who desired to foster in his students a “love of nature,” which, he said, “should give health to any one, and supply knowledge of greatest value, either to the individual or to society, or to both.” In this biography of a prominent scientist now almost forgotten, Dennison—longtime president of the University of Montana—demonstrates how Elrod’s scholarship and philosophy regarding science and nature made him one of Montana’s most distinguished naturalists, conservationists, and educators.

Download or read book Enhancing the Value and Sustainability of Field Stations and Marine Laboratories in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2014-09-11 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over a century, field stations have been important entryways for scientists to study and make important discoveries about the natural world. They are centers of research, conservation, education, and public outreach, often embedded in natural environments that range from remote to densely populated urban locations. Because they lack traditional university departmental boundaries, researchers at field stations have the opportunity to converge their science disciplines in ways that can change careers and entire fields of inquiry. Field stations provide physical space for immersive research, hands-on learning, and new collaborations that are otherwise hard to achieve in the everyday bustle of research and teaching lives on campus. But the separation from university campuses that allows creativity to flourish also creates challenges. Sometimes, field stations are viewed as remote outposts and are overlooked because they tend to be away from population centers and their home institutions. This view is exacerbated by the lack of empirical evidence that can be used to demonstrate their value to science and society. Enhancing the Value and Sustainability of Field Stations and Marine Laboratories in the 21st Century summarizes field stations' value to science, education, and outreach and evaluates their contributions to research, innovation, and education. This report suggests strategies to meet future research, education, outreach, infrastructure, funding, and logistical needs of field stations. Today's technologies - such as streaming data, remote sensing, robot-driven monitoring, automated DNA sequencing, and nanoparticle environmental sensors - provide means for field stations to retain their special connection to nature and still interact with the rest of the world in ways that can fuel breakthroughs in the environmental, physical, natural, and social sciences. The intellectual and natural capital of today's field stations present a solid platform, but many need enhancements of infrastructure and dynamic leadership if they are to meet the challenges of the complex problems facing the world. This report focuses on the capability of field stations to address societal needs today and in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Field Life examines the practice of science in the field in the Great Plains and Rocky Mountains of the American West between the 1860s and the 1910s, when the railroad was the dominant form of long-distance transportation. Grounded in approaches from environmental history and the history of technology, it emphasizes the material basis of scientific fieldwork, joining together the human labor that produced knowledge with the natural world in which those practices were embedded. Four distinct modes of field practice, which were shared by different field science disciplines, proliferated during this period—surveys, lay networks, quarries, and stations—and this book explores the dynamics that underpinned each of them. Using two diverse case studies to animate each mode of practice, as well as the making of the field as a place for science, Field Life combines textured analysis of specific examples of field science on the ground with wider discussion of the commonalities in the practices of a diverse array of field sciences, including the earth and physical sciences, the life and agricultural sciences, and the human sciences. By situating science in its regional environmental context, Field Life analyzes the intersection between the cosmopolitan knowledge of science and the experiential knowledge of people living in the field. Examples of field science in the Plains and Rockies range widely: geological surveys and weather observing networks, quarries to uncover dinosaur fossils and archaeological remains, and branch agricultural experiment stations and mountain biological field stations.

Available in PDF, EPUB and Kindle. Book excerpt: Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).
