The Ecology of Dust


Book Description

Emission and redistribution of dust due to wind erosion in drylands drives major biogeochemical dynamics and provides important aeolian environmental connectivity at scales from individual plants up to the global scale. Yet, perhaps because most relevant research on aeolian processes has been presented in a geosciences rather than ecological context, most ecological studies do not explicitly consider dust-driven processes. To bridge this disciplinary gap, we provide a general overview of the ecological importance of dust, examine complex interactions between wind erosion and ecosystem dynamics from the plant-interspace scale to regional and global scales, and highlight specific examples of how disturbance affects these interactions and their consequences. Changes in climate and intensification of land use will both likely lead to increased dust production. To address these challenges, environmental scientists, land managers and policy makers need to more explicitly consider dust in resource management decisions.




Dust Bowl


Book Description

In the mid 1930s, North America's Great Plains faced one of the worst man-made environmental disasters in world history. Donald Worster's classic chronicle of the devastating years between 1929 and 1939 tells the story of the Dust Bowl in ecological as well as human terms.Now, twenty-five years after his book helped to define the new field of environmental history, Worster shares his more recent thoughts on the subject of the land and how humans interact with it. In a new afterword, he links the Dust Bowl to current political, economic and ecological issues--including the American livestock industry's exploitation of the Great Plains, and the on-going problem of desertification, which has now become a global phenomenon. He reflects on the state of the plains today and the threat of a new dustbowl. He outlines some solutions that have been proposed, such as "the Buffalo Commons," where deer, antelope, bison and elk would once more roam freely, and suggests that we may yet witness a Great Plains where native flora and fauna flourish while applied ecologists show farmers how to raise food on land modeled after the natural prairies that once existed.




Dust Mites


Book Description

Conservatively, at least 100 million people are affected by house dust mite allergy worldwide, manifesting itself as asthma, rhinitis or atopic dermatitis. Despite the growing recognition of this major public health problem, and commitment of considerable research resources, there is still no simple, effective, generally-applicable strategy for dust mite control. The reasons for this are complex, but a contributing factor remains some important knowledge gaps and misconceptions regarding aspects of biology and ecology of dust mites. The purpose of this book is to provide a comprehensive reference work for all readers with an involvement or interest in house dust mite research and management, incorporating for the first time in a single volume the topics of systematics and identification, physiology, ecology, allergen biochemistry and molecular biology, epidemiology, mite control and allergen avoidance. It is hoped the book will help spread the message that studies of the biology and ecology of house dust mites should be regarded within the context of allergic disease rather than as ends in themselves, and that approaches to mite control in clinical management are subject to the same series of ecological rules as any other major problem in pest management.




Aeolian Dust and Dust Deposits


Book Description

Aeolian Dust and Dust Deposits explores the entrainment, dispersion, and deposition of aeolian dust and dust deposits, with emphasis on transport and deposition of dust derived by deflation of surface sediments and soils. Topics covered range from the mechanisms of fine-particle formation to dust sources, sinks, and rates of deposition. Dust-transporting wind systems are also discussed, along with the grain size, mineralogy, and chemical composition of aeolian dust. Comprised of nine chapters, this book begins with an overview of the general nature and significance of windborne dust as well as the importance of aeolian dust and loess. The next chapter deals with the mechanisms underlying the formation of fine particles, including glacial grinding, frost and salt weathering, and fluvial comminution. The reader is then introduced to dust entrainment, transport, and deposition, together with dust sources, sinks, and rates of deposition. Subsequent chapters focus on the implications of dust deflation, transport, and deposition; dust deposition in the oceans; and loess distribution and the thickness and morphology of loess deposits. This monograph is written primarily for research workers and advanced students in sedimentology, geomorphology, and Quaternary studies, but is also likely to be of value to soil scientists, meteorologists, planetary geologists, engineers, and others concerned with environmental management.




Desert Dust in the Global System


Book Description

Dust storms are a vital component of the environment. This book explores and summarises recent research on where dust storms originate, why dust storms are generated, where dust is transported and deposited, the nature of dust deposits and the changing frequency of dust storms over a range of time-scales. It is the first global study of causes and effects of dust storms, which are one of the increasing nature catastrophes.




Ecology


Book Description

Publishes essays and articles that report and interpret the results of original scientific research in basic and applied ecology.




Lives of Dust and Water


Book Description

Along the coast of northwestern Mexico, "pink gold" may mean wealth for some, but the new global economy has imposed terrible burdens on many sectors of the population. State and regional economic development policies have supported the use of natural resources for commercial export, resulting in the rapid growth of agriculture and shrimp aquaculture. Environmental pressures have contributed to the degradation of marine ecosystems, and once self-reliant rural populations have been driven to wage and subsistence labor in order to survive. This book eloquently explains how contemporary rural communities in southern Sinaloa have responded to economic and ecological changes affecting the entire nation. A political ecology of human survival in one of the most important ecological regions of Mexico, it describes how these communities contest environmental degradation and economic impoverishment arising from political and economic forces beyond their control. Mar’a Luz Cruz-Torres evokes the rich and varied experiences of the people who live in the villages of Celaya and El Cerro, showing how they invent and utilize their own social capital to emerge as whole persons in the face of globalization. She traces the histories of the two villages to illustrate the complex variation involved in community formation and to show how people respond to and utilize Mexican law and reform. Surrounded by limited resources, poverty, illness, sudden death, and daily oppression, these men and women create innovative social and cultural forms that mitigate these impacts. Cruz-Torres reveals not only how they manage to survive in the midst of horrendous circumstances but also how they transcend those impediments with dignity. She details the participation of household members in the subsistence, formal, and informal sectors of the economy, and how women use a variety of resources to guarantee their familiesÕ survival. A sometimes tragic but ultimately vibrant story of human resistance, Lives of Dust and Water offers an important look at a little-studied but dynamically developing region of Mexico. It contributes to a more precise understanding of how rural coastal communities in Mexico emerged and continue to develop and adjust to the uncertainties of the globalizing world.




The Ecological World View


Book Description

Filled with many examples of topic issues and current events, this book develops a basic understanding of how the natural world works and of how humans interact with the planet's natural ecosystems. It covers the history of ecology and describes the general approaches of the scientific method, then takes a look at basic principles of population dynamics and applies them to everyday practical problems.




Ecology of Desert Systems


Book Description

Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. Highlights the complexity of global desert systems in a clear, concise way Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems




Desert Dust in the Global System


Book Description
