This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.

Grasslands are areas where the vegetation is dominated by grasses (Poaceae) and other herbaceous (non-woody) plants (forbs). Plants of the sedge (Cyperacae) and rush (Juncaceae) families can also be frequent in grasslands. Grasslands occur naturally on all continents except Antarctica, and in many other areas they have replaced the natural vegetation due to human influence. In temperate latitudes, such as north-west Europe, grasslands are dominated by perennial species, whereas in warmer climates annual species form a greater component of the vegetation. Grasslands can be found in most terrestrial climates. Grassland vegetation can vary in height from very short, as in chalk downland where the vegetation may be less than 30 cm high, to quite tall, as in the case of North American tallgrass prairie, South American grasslands and African savannah. Woody plants, shrubs or trees, may occur on some grasslands - forming wooded, scrubby or semi-wooded grassland, such as the African savannahs or the Iberian dehesa. Such grasslands are sometimes referred to as wood-pasture or Savannah woodland. Grasslands cover nearly fifty percent of the land surface of the continent of Africa. This book gathers new and important research from around the world in this field.

This book chronicles and explains the role of suburbs in North American cities since the mid-twentieth century. Examining fifteen case studies from New York to Vancouver, Atlanta to Chicago, Montreal to Phoenix, The Life of North American Suburbs traces the insightful connection between the evolution of suburbs and the cultural dynamics of modern society. Suburbs are uniquely significant spaces: their creation and evolution reflect the shifting demographics, race relations, modes of production, cultural fabric, and class structures of society at large. The case studies investigate the place of suburbs within their wider metropolitan constellations: the crucial role they play in the cultural, economic, political, and spatial organization of the city. Together, the chapters paint a compelling portrait of North American cities and their dynamic suburban landscapes.

Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.

Not Good Enough for Canada investigates the development of Canadian immigration policy with respect to persons with a disease or disability throughout the twentieth century. With an emphasis on social history, this book examines the way the state operates through legislation to achieve its goals of self-preservation even when such legislation contradicts state commitments to equality rights. Looking at the ways federal politicians, mainstream media, and the judicial system have perceived persons with disabilities, specifically immigrant applicants with disabilities, this book reveals how Canadian immigration policy has systematically omitted any reference to this group, rendering them socially invisible.

Grasslands are the most extensive terrestrial biome on Earth and are critically important for forage, biodiversity, and ecosystem services. This book brings together an international team of researchers to review scientific knowledge of the effects of climate change on world grasslands, a process we are only just starting to understand. Part I assesses how climate change will impact on the distribution of grasslands, as well as production, biogeochemical cycling and ecosystem services. Part II considers the consequences for the spread of invasive species, demographic change, trophic-level relationships, soil biota, and evolutionary change within grassland biodiversity. Part III proposes how ecologists can respond to climate change effects, focusing on grazing systems, cultural ecology, range management, and restoration. The concluding chapter sets grasslands in the context of the Anthropocene era and identifies the vital research and conservation needs for grassland ecosystems to remain environmentally sustainable under climate change.

Many historians and political scientists argue that ties between Canada and Latin America have been weak and intermittent because of lack of mutual interest and common objectives. Has this record of diverging paths changed as Canada has attempted to expand its economic and diplomatic ties with the region? Has Canada become an imperialist power? Canada's Past and Future in Latin America investigates the historical origins of and more recent developments in Canadian foreign policy in the region. It offers a detailed evaluation of the Harper and Trudeau governments' approaches to Latin America, touching on political diplomacy, bilateral development cooperation, and civil society initiatives. Leading scholars of Canada-Latin America relations offer insights from unique perspectives on a range of issues, such as the impact of Canadian mining investment, security relations, democracy promotion, and the changing nature of Latin American migration to Canada. Drawing on archival research, field interviews, and primary sources, Canada's Past and Future in Latin America advances our understanding of Canadian engagement with the region and evaluates options for building stronger ties in the future.

2020 Nebraska Book Award The Great Plains is a well-known and well-studied hybrid zone for many animals, most notably birds. In Great Plains Birds Larkin Powell explores the history, geography, and geology of the plains and the birds that inhabit it. From the sandhill crane to ducks and small shorebirds, he explains migration patterns and shows how human settlements have affected the movements of birds. Powell uses historical maps and images to show how wetlands have disappeared, how grasslands have been uprooted, how rivers have been modified by dams, and how the distribution of forests has changed, all the while illustrating why grassland birds are the most threatened group of birds in North America. Powell also discusses conservation attempts and how sporting organizations have raised money to create wetland and grassland habitats for both game and nongame species. Great Plains Birds tells the story of the birds of the plains, discussing where those birds can be found and the impact humans have had on them.

In People of the Ecotone, Robert Morrissey weaves together a history of Native peoples with a history of an ecotone to tell a new story about the roots of the Fox Wars, among the most transformative and misunderstood events of early American history. To do this, he also offers the first comprehensive environmental history of some of North America’s most radically transformed landscapes—the former tallgrass prairies—in the period before they became the monocultural “corn belt” we know today. Morrissey situates the complex rise and fall of the Illinois, Meskwaki, and Myaamia peoples from roughly the collapse of Cahokia (thirteenth to fourteenth century CE) to the mid-eighteenth century in the context of millennia-long environmental shifts, as changes to the climate shifted bison geographies and tribes adapted their cultures to become pedestrian bison hunters. Tracing dynamic chains of causation from microscopic viruses to massive forces of climate, from the deep time of evolution to the specific events of human lifetimes, from local Illinois village economies to market forces an ocean away, People of the Ecotone offers new insight on Indigenous power and Indigenous logics.

When looking at old pictures of Toronto, it is clear that the city’s urban, economic, and social geography has changed dramatically over the generations. Historic photos of Toronto’s streetcar network offer a unique opportunity to examine how the city has been transformed from a provincial, industrial city into one of North America’s largest and most diverse regions. Streetcars and the Shifting Geographies of Toronto studies the city’s urban transformations through an analysis of photographs taken by streetcar enthusiasts, beginning in the 1960s. These photographers did not intend to record the urban form, function, or social geographies of Toronto; they were "accidental archivists" whose main goal was to photograph the streetcars themselves. But today, their images render visible the ordinary, day-to-day life in the city in a way that no others did. These historic photographs show a Toronto before gentrification, globalization, and deindustrialization. Each image has been re-photographed to provide fresh insights into a city that is in a constant state of flux. With gorgeous illustrations, this unique book offers an understanding of how Toronto has changed, and the reasons behind these urban shifts. The visual exploration of historic and contemporary images from different parts of the city helps to explain how the major forces shaping the city affect its form, functions, neighbourhoods, and public spaces.

The Greater Plains tells a new story of a region, stretching from the state of Texas to the province of Alberta, where the environments are as varied as the myriad ways people have inhabited them. These innovative essays document a complicated history of human interactions with a sometimes plentiful and sometimes foreboding landscape, from the Native Americans who first shaped the prairies with fire to twentieth-century oil regimes whose pipelines linked the region to the world. The Greater Plains moves beyond the narrative of ecological desperation that too often defines the region in scholarly works and in popular imagination. Using the lenses of grasses, animals, water, and energy, the contributors reveal tales of human adaptation through technologies ranging from the travois to bookkeeping systems and hybrid wheat. Transnational in its focus and interdisciplinary in its scholarship, The Greater Plains brings together leading historians, geographers, anthropologists, and archaeologists to chronicle a past rich with paradoxical successes and failures, conflicts and cooperation, but also continual adaptation to the challenging and ever-shifting environmental conditions of the North American heartland.

British Plant Communities is the first systematic and comprehensive account of the vegetation types of this country. It covers all natural, semi-natural and major artificial habitats in Great Britain (but not Northern Ireland), representing the fruits of fifteen years of research by leading plant ecologists. The book breaks new ground in wedding the rigorous interest in the classification of plant communities that has characterized Continental phytosociology with the deep concern traditional in Great Britain to understand how vegetation works. The published volumes have been greeted with universal acclaim, and the series has become firmly established as a framework for a wide variety of teaching, research and management activities in ecology, conservation and land-use planning.

British Plant Communities is the first systematic and comprehensive account of natural vegetation types of Great Britain. It covers all natural, semi-natural and major artificial habitats in Great Britain (excluding Northern Ireland), representing the fruits of fifteen years research by leading plant ecologists. Over 250 plant communities are described in the five volumes, with summaries of their vascular plants, bryophytes and lichens. There are full details in the text of the composition and structure of the vegetation, its relationships to habitat factors and its occurence in characteristic spatial patterns and successions. Numerous maps show the distribution of the communities through Britain and all the vegetation types are related to their closest equivalents in mainland Europe. For each major group of communities an introduction outlines the range of floristic variation and relates it to important environmental influences. A key provides the reader with a means of identifying vegetation types encountered in the field. There are indices to the communities and to their existing synonyms, and to all the plant species encountered in the survey. An extensive bibliography gives full details of the numerous literature references cited. British Plant Communities breaks new ground in wedding traditional Continental phytosociology with the deep concern in Britain to understand how vegetation works. It is intended as a working tool, offering a reliable framework for a wide variety of teaching, research, and management activities in ecology, conservation, and land use planning.

Grassland ecosystems are deeply affected by human activities and need appropriate management to optimise trade-offs between ecosystem functions and services. Until now they have mainly been analysed as agro-ecosystems for animal production but this book looks beyond the role of grassland as a feeding ground, and evaluates other important processes such as carbon sequestration in soils, greenhouse gas regulation and biodiversity protection. This authoritative volume expertly highlights the need for an immediate balance between agriculture and ecological management for sustainability in the future.

Following the destruction of 95% of meadows during the twentieth century, there is an urgent need to understand what little unspoiled habitat remains in order to plan the management and restoration of existing sites, as well as re-creating future grassland habitats. This book is a much-needed guide to grassland restoration and management. Providing a thorough overview of recent research on grassland restoration and its implications for practical grassland restoration and management, it introduces grassland communities and the wildlife they support, including examples of species of conservation concern, and considers the management of semi-natural grassland habitats with particular emphasis on drier grassland habitats. Chapters cover: - Grassland character and communities - Introduction to grassland wildlife - Managing semi-natural grassland - Grassland restoration - threats and challenges - Opportunities in grassland restoration - Plant material for grassland restoration - Defining success in grassland restoration. A variety of management techniques are examined, including soil amendment, cultivation, harvesting and maintenance in creating suitable conditions for the successful restoration of species-rich grasslands. It is essential reading for conservationists, site owners or managers, practitioners, conservation organizations and students of ecological restoration with an interest in the creation of new grassland habitats, the restoration of semi-natural grassland, as well as the continuing management of semi-natural (unimproved) grassland communities.

In Wildlife of Nebraska: A Natural History, Paul A. Johnsgard surveys the variety and biology of more than six hundred Nebraska species. Narrative accounts describe the ecology and biology of the state's birds, its mammals, and its reptiles and amphibians, summarizing the abundance, distributions, and habitats of this wildlife. To provide an introduction to the state's major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.

The inaction of nation states and international bodies has posed significant risks to the environment. By contrast, cities are sites of action and innovation. In Sustainability, Citizen Participation, and City Governance, contributors researching in the areas of law, urban planning, geography, and philosophy identify approaches for tackling many of the most challenging environmental problems facing cities today. Sustainability, Citizen Participation, and City Governance facilitates two strands of dialogue about climate change. First, it integrates legal perspectives into policy debates about urban sustainability and governance, from which law has typically stood apart. Second, it brings case studies from Quebec into a rare conversation with examples drawn from elsewhere in Canada. The collection proposes humane and inclusive processes for arriving at effective policy outcomes. Some chapters examine governance mechanisms that reconcile clashes of incommensurable values and resolve conflicts about collective interests. Other chapters provide platforms for social movements that have faced obstacles to communicating to a broad public. The collection's proposals respond to drastic changes in urban environments. Some changes are imminent. Others are upon us already. All threaten the present and future well-being of urban communities.

For thirty years David G. Campbell has explored the Amazon, an enchanting terrain of forest and river that is home to the greatest diversity of plants and animals to have ever existed, anywhere at any time, during the four-billion-year history of life on Earth. With great artistic flair, Campbell describes a journey up the Rio Moa, a remote tributary of the Amazon River, 2,800 miles from its mouth. Here he joins three old friends: Arito, a caiman hunter turned paleontologist; Tarzan, a street urchin brought up in a bordello; and Pimentel, a master canoe pilot. They travel together deep into the rainforest and set up camp in order to survey every woody plant on a two-hectare plot of land with about as many tree species as in all of North America. Campbell introduces us to two remarkable women, Dona Cabocla, a widow who raised six children on that lonely frontier, and Dona Ausira, a Nokini Native American who is the last speaker of her tribe's ages-old language. These pioneers live in a land whose original inhabitants were wiped out by centuries of disease, slavery, and genocide, taking their traditions and languages with them. He explores the intimate relationship between the extinction of native language and the extirpation of biological diversity. "It's hard for a people to love a place that is not defined in words and thus cannot be understood. And it's easy to give away something for which there are no words, something you never knew existed." In elegant prose that enchants and entrances, Campbell has written an elegy for the Amazon forest and its peoples-for what has become a land of ghosts.

The Chicago metropolitan area is home to far more protected nature than most people realize. Over half a million acres of protected land known as the Chicago Wilderness are owned and managed by county forest preserve districts and other public and private sector partners. But there’s a critical factor of the Chicago Wilderness conservation effort that makes it unique: a pioneering grassroots volunteer community, thousands strong, has worked for decades alongside agency staff to restore these nearby natural areas, learning how to manage biodiversity in an altered and ever-changing urban context. A Healthy Nature Handbook captures hard-earned ecological wisdom from this community in engaging and highly readable chapters, each including illustrated restoration sequences. Restoration leaders cover large-scale seeding approaches, native seed production, wetland and grassland bird habitat restoration, monitoring, and community building. Contributions from local artists bring the region’s beauty to life with vibrant watercolors, oil paintings, and sketches. A Healthy Nature Handbook is packed with successful approaches to restoring nature and is a testament to both the Chicago region’s surprising natural wealth and the stewards that are committed to its lasting health.

While the imperiled Brazilian rainforest has been the focus of considerable international media attention and conservation efforts, the massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little notice. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.
