G. Evelyn Hutchinson and the Invention of Modern Ecology

G. Evelyn Hutchinson and the Invention of Modern Ecology PDF Author: Nancy G. Slack
Publisher: Yale University Press
ISBN: 0300161387
Category : Science
Languages : en
Pages : 477

Book Description
Slack enjoyed full access to Hutchinson's archives and conducted extensive interviews both with Hutchinson himself and with his students, colleagues, and friends. She evaluates his contributions to theoretical ecology, limnology (the study of fresh-water ecosystems), biogeochemistry, population ecology, and the creation of the new fields of systems ecology and radiation ecology, and she discusses his profound influence as a mentor. The book also looks into his personal life, which included three very different wives, a refugee baby under his care during World War II, friendships with such contemporaries as Rebecca West, Margaret Mead, and Gregory Bateson, and a host of colleagues and friends on four continents. Filled with information available nowhere else, this book draws a vibrant portrait of a giant in the discipline of twentieth-century ecology who was also a man of remarkable personal appeal. --Book Jacket.

Water for Food Water for Life

Water for Food Water for Life PDF Author: David Molden
Publisher: Routledge
ISBN: 113654853X
Category : Law
Languages : en
Pages : 664

Book Description
Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

Invasive and Introduced Plants and Animals

Invasive and Introduced Plants and Animals PDF Author: Ian D. Rotherham
Publisher: Routledge
ISBN: 1134061951
Category : Science
Languages : en
Pages : 393

Book Description
There have been many well-publicized cases of invasive species of plants and animals, often introduced unintentionally but sometimes on purpose, causing widespread ecological havoc. Examples of such alien invasions include pernicious weeds such as Japanese knotweed, an introduced garden ornamental which can grow through concrete, the water hyacinth which has choked tropical waterways, and many introduced animals which have out-competed and displaced local fauna. This book addresses the broader context of invasive and exotic species, in terms of the perceived threats and environmental concerns which surround alien species and ecological invasions. As a result of unprecedented scales of environmental change, combined with rapid globalisation, the mixing of cultures and diversity, and fears over biosecurity and bioterrorism, the known impacts of particular invasions have been catastrophic. However, as several chapters show, reactions to some exotic species, and the justifications for interventions in certain situations, including biological control by introduced natural enemies, rest uncomfortably with social reactions to ethnic cleansing and persecution perpetrated across the globe. The role of democracy in deciding and determining environmental policy is another emerging issue. In an increasingly multicultural society this raises huge questions of ethics and choice. At the same time, in order to redress major ecological losses, the science of reintroduction of native species has also come to the fore, and is widely accepted by many in nature conservation. However, with questions of where and when, and with what species or even species analogues, reintroductions are acceptable, the topic is hotly debated. Again, it is shown that many decisions are based on values and perceptions rather than objective science. Including a wide range of case studies from around the world, his book raises critical issues to stimulate a much wider debate.

Sustainability or Collapse?

Sustainability or Collapse? PDF Author: Robert Costanza
Publisher: MIT Press
ISBN: 0262515970
Category : Science
Languages : en
Pages : 518

Book Description
Scholars from a range of disciplines develop an integrated human and environmental history over millennial, centennial, and decadal time scales and make projections for the future. Human history, as written traditionally, leaves out the important ecological and climate context of historical events. But the capability to integrate the history of human beings with the natural history of the Earth now exists, and we are finding that human-environmental systems are intimately linked in ways we are only beginning to appreciate. In Sustainability or Collapse?, researchers from a range of scholarly disciplines develop an integrated human and environmental history over millennial, centennial, and decadal time scales and make projections for the future. The contributors focus on the human-environment interactions that have shaped historical forces since ancient times and discuss such key methodological issues as data quality. Topics highlighted include the political ecology of the Mayans; the effect of climate on the Roman Empire; the "revolutionary weather" of El Niño from 1788 to 1795; twentieth-century social, economic, and political forces in environmental change; scenarios for the future; and the accuracy of such past forecasts as The Limits to Growth.

On Gaia

On Gaia PDF Author: Toby Tyrrell
Publisher: Princeton University Press
ISBN: 0691121583
Category : Science
Languages : en
Pages : 324

Book Description
A critical examination of James Lovelock's controversial Gaia hypothesis One of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others—and concludes that the evidence doesn't stack up in support of Gaia. Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact. On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable—or against poor stewardship by us.

Understanding Human Ecology

Biogeochemistry of Forested Catchments in a Changing Environment

Biogeochemistry of Forested Catchments in a Changing Environment PDF Author: Egbert Matzner
Publisher: Springer Science & Business Media
ISBN: 3662060736
Category : Science
Languages : en
Pages : 506

Book Description
Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITÖK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITÖ K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.

The Rediscovery of the Wild

The Rediscovery of the Wild PDF Author: Peter H. Kahn, Jr.
Publisher: MIT Press
ISBN: 0262312832
Category : Nature
Languages : en
Pages : 277

Book Description
A compelling case for connecting with the wild, for our psychological and physical well-being and to flourish as a species We often enjoy the benefits of connecting with nearby, domesticated nature—a city park, a backyard garden. But this book makes the provocative case for the necessity of connecting with wild nature—untamed, unmanaged, not encompassed, self-organizing, and unencumbered and unmediated by technological artifice. We can love the wild. We can fear it. We are strengthened and nurtured by it. As a species, we came of age in a natural world far wilder than today's, and much of the need for wildness still exists within us, body and mind. The Rediscovery of the Wild considers ways to engage with the wild, protect it, and recover it—for our psychological and physical well-being and to flourish as a species. The contributors offer a range of perspectives on the wild, discussing such topics as the evolutionary underpinnings of our need for the wild; the wild within, including the primal passions of sexuality and aggression; birding as a portal to wildness; children's fascination with wild animals; wildness and psychological healing; the shifting baseline of what we consider wild; and the true work of conservation.
