Download or read book Bioinvaders written by Sarah Johnson and published by . This book was released on 2010 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are pleased to announce a new series of environmental history readers, suitable for students. Comprising essays selected from our journals, Environment and History and Environmental Values, each inexpensive paperback volume will address an important theme in environmental history, combining underlying theory and specific case-studies. The first volume, Bio-invaders, investigates the rhetoric and realities of exotic, introduced and 'alien' species. The book comprises a number of general essays, exploring and challenging common perceptions about such species, and a series of case studies of specific species in specific contexts. Its geographical coverage ranges from the United Kingdom to New Zealand by way of South Africa, India and Palestine; and the essays cover both historical and recent introductions.
Download or read book Wildland Fuel Fundamentals and Applications written by Robert E. Keane and published by Springer. This book was released on 2014-11-04 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management. There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections. This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics. The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives. This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book It s Different for Daughters written by Ruth Fry and published by . This book was released on 1985 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study of the curriculum for girls from the beginning of this century brings a fresh perspective to New Zealand educational history. Following the early triumphs of gaining the vote (and the right to qualify for university degrees), progress in women's education was not always straightforward. Social attitudes and provisions for girls at state schools in the first quarter-century established patterns for later generations to inherit and modify. In some areas, such as science and mathematics, inequalities for Maori girls lingered. Using a wide range of resources, ruth Fry traces the origin and development of the curriculum for girls to 1975, International Women's year. Those who, in 1893, achieved success in their campaign for equal voting rights were also concerned about educational opportunities for women. NZCER is very pleased to reissue It's different for daughters to celebrate the Centenary of Women's Suffrage in New Zealand.
Download or read book A Century of Wildland Fire Research written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-09-30 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although ecosystems, humans, and fire have coexisted for millennia, changes in geology, ecology, hydrology, and climate as well as sociocultural, regulatory, and economic factors have converged to make wildland fire management exceptionally challenging for U.S. federal, state, and local authorities. Given the mounting, unsustainable costs and difficulty translating existing wildland fire science into policy, the National Academies of Sciences, Engineering, and Medicine organized a 1-day workshop to focus on how a century of wildland fire research can contribute to improving wildland fire management. This publication summarizes the presentations and discussions from the workshop.
Download or read book Vetiver Grass written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
Download or read book Mushrooms Humans and Nature in a Changing World written by Jesús Pérez-Moreno and published by Springer Nature. This book was released on 2020-04-28 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on recent advances in our understanding of wild edible mycorrhizal fungi, truffle and mushrooms and their cultivation. In addition to providing fresh insights into various topics, e.g. taxonomy, ecology, cultivation and environmental impact, it also demonstrates the clear but fragile link between wild edible mushrooms and human societies. Comprising 17 chapters written by 41 experts from 13 countries on four continents, it enables readers to grasp the importance of protecting this unique, invaluable, renewable resource in the context of climate change and unprecedented biodiversity loss. The book inspires professionals and encourages young researchers to enter this field to develop the sustainable use of wild edible mushrooms using modern tools and approaches. It also highlights the importance of protecting forested environments, saving species from extinction and generating a significant income for local populations, while keeping alive and renewing the link between humans and wild edible mushrooms so that in the future, the sustainable farming and use of edible mycorrhizal mushrooms will play a predominant role in the management and preservation of forested lands.
