Linking Restoration and Ecological Succession (Hardcover, 2007 ed.): Lawrence R. Walker, Joe Walker, Richard J. Hobbs Linking Restoration and Ecological Succession (Hardcover, 2007 ed.)
Lawrence R. Walker, Joe Walker, Richard J. Hobbs
R2,817 Discovery Miles 28 170 Ships in 18 - 22 working days

This innovative book integrates practical information from restoration projects around the world with the latest developments in successional theory. It recognizes the critical roles of disturbance ecology, landscape ecology, ecological assembly, invasion biology, ecosystem health, and historical ecology in habitat restoration. It argues that restoration within a successional context will best utilize the lessons from each of these disciplines.

Long-Term Ecological Research - Changing the Nature of Scientists (Hardcover): Michael R Willig, Lawrence R. Walker Long-Term Ecological Research - Changing the Nature of Scientists (Hardcover)

R2,757 Discovery Miles 27 570 Ships in 10 - 15 working days

The Long-Term Ecological Research (LTER) Program is, in a sense, an experiment to transform the nature of science, and represents one of the most effective mechanisms for catalyzing comprehensive site-based research that is collaborative, multidisciplinary, and long-term in nature. The scientific contributions of the Program are prodigious, but the broader impacts of participation have not been examined in a formal way. This book captures the consequences of participation in the Program on the perspectives, attitudes, and practices of environmental scientists. The edited volume comprises three sections. The first section includes two chapters that provide an overview of the history, goals, mission, and inner workings of the LTER network of sites. The second section comprises three dozen retrospective essays by scientists, data managers or educators who represent a broad spectrum of LTER sites from deserts to tropical forests and from arctic to marine ecosystems. Each essay addresses the same series of probing questions to uncover the extent to which participation has affected the ways that scientists conduct research, educate students, or provide outreach to the public. The final section encompasses 5 chapters, whose authors are biophysical scientists, historians, behavioral scientists, or social scientists. This section analyzes, integrates, or synthesizes the content of the previous chapters from multiple perspectives and uncovers emergent themes and future directions.

Landslide Ecology (Hardcover, New): Lawrence R. Walker, Aaron B. Shiels Landslide Ecology (Hardcover, New)
Lawrence R. Walker, Aaron B. Shiels
R2,748 Discovery Miles 27 480 Ships in 10 - 15 working days

Despite their often dangerous and unpredictable nature, landslides provide fascinating templates for studying how soil organisms, plants and animals respond to such destruction. The emerging field of landslide ecology helps us understand these responses, aiding slope stabilisation and restoration and contributing to the progress made in geological approaches to landslide prediction and mitigation. Summarising the growing body of literature on the ecological consequences of landslides, this book provides a framework for the promotion of ecological tools in predicting, stabilising, and restoring biodiversity to landslide scars at both local and landscape scales. It explores nutrient cycling; soil development; and how soil organisms disperse, colonise and interact in what is often an inhospitable environment. Recognising the role that these processes play in providing solutions to the problem of unstable slopes, the authors present ecological approaches as useful, economical and resilient supplements to landslide management.

Island Environments in a Changing World (Hardcover): Lawrence R. Walker, Peter Bellingham Island Environments in a Changing World (Hardcover)

Islands represent unique opportunities to examine human interaction with the natural environment. They capture the human imagination as remote, vulnerable and exotic, yet there is comparatively little understanding of their basic geology, geography, or the impact of island colonization by plants, animals and humans. This detailed study of island environments focuses on nine island groups, including Hawaii, New Zealand and the British Isles, exploring their differing geology, geography, climate and soils, as well as the varying effects of human actions. It illustrates the natural and anthropogenic disturbances common to island groups, all of which face an uncertain future clouded by extinctions of endemic flora and fauna, growing populations of invasive species, and burgeoning resident and tourist populations. Examining the natural and human history of each island group from early settlement onwards, the book provides a critique of the concept of sustainable growth and offers realistic guidelines for future island management.

The Biology of Disturbed Habitats (Hardcover): Lawrence R. Walker The Biology of Disturbed Habitats (Hardcover)
Lawrence R. Walker
R2,907 Discovery Miles 29 070 Ships in 10 - 15 working days

This book provides the first global synthesis of the biology of disturbed habitats and offers readers both the conceptual underpinnings and practical advice required to comprehend and address the unprecedented environmental challenges facing humans. Every habitat on earth has been impacted by natural disturbances such as volcanoes, earthquakes, landslides, fires, floods, and droughts. Humans have contributed many additional disturbances such as mining, urbanization, forestry, agriculture, fishing, and recreation. These anthropogenic disturbances modify and often exacerbate the effects of the natural disturbances. Together, they result in the abrupt loss of biomass or ecosystem structure and function to create denuded surfaces where novel mixtures of native and non-native microbes, plants, and animals establish, grow, and die. The Biology of Disturbed Habitats examines both natural and anthropogenic disturbances in aquatic and terrestrial habitats. It explores how nutrients and productivity are altered in the disturbed habitats, the effects of disturbance on biodiversity, and the spatial and temporal dynamics of organisms that colonize disturbed habitats. This book also addresses how to manage disturbances through appropriate conservation and restoration measures, and discusses how climate change and overpopulation now represent the most challenging disturbances at a global scale.

R1,849 Discovery Miles 18 490 Ships in 10 - 15 working days

Ferns are an integral part of the world's flora, appreciated for their beauty as ornamentals, problematic as invaders and endangered by human interference. They often dominate forest understories but also colonize open areas, invade waterways and survive in nutrient-poor wastelands and eroded pastures. Presented here is the first comprehensive summary of fern ecology, with worldwide examples from Siberia to the islands of Hawaii. Topics include a brief history of the ecological study of ferns, a global survey of fern biogeography, fern population dynamics, the role of ferns in ecosystem nutrient cycles, their adaptations to xeric environments and future directions in fern ecology. Fully illustrated concepts and processes provide a framework for future research and utilization of ferns for graduate students and professionals in ecology, conservation and land management.

Environmental Disasters, Natural Recovery and Human Responses (Paperback): Roger Del Moral, Lawrence R. Walker Environmental Disasters, Natural Recovery and Human Responses (Paperback)
Roger Del Moral, Lawrence R. Walker
R1,287 Discovery Miles 12 870 Ships in 10 - 15 working days

Natural disasters destroy more property and kill more people with each passing year. Volcanic eruptions, earthquakes, hurricanes, tsunamis, floods, landslides, fires and other natural events are becoming more frequent and their consequences more devastating. Del Moral and Walker provide a comprehensive summary of the diverse ways in which natural disasters disrupt humanity and how humans cope. Burgeoning human numbers, shrinking resources and intensification of the consequences of natural disasters have produced a crisis of unparalleled proportions. Through this detailed study, the authors provide a template for improving restoration to show how relatively simple approaches can enhance both human well-being and that of the other species on the planet. This book will appeal to ecologists, land managers as well as anyone curious about the natural world and natural disasters.

Comparative Plant Succession among Terrestrial Biomes of the World (Paperback): Karel Prach, Lawrence R. Walker Comparative Plant Succession among Terrestrial Biomes of the World (Paperback)
Karel Prach, Lawrence R. Walker
R1,313 Discovery Miles 13 130 Ships in 10 - 15 working days

Despite a century of study by ecologists, recovery following disturbances (succession) is not fully understood. This book provides the first global synthesis that compares plant succession in all major terrestrial biomes and after all major terrestrial disturbances. It asks critical questions such as: Does succession follow general patterns across biomes and disturbance types? Do factors that control succession differ from biome to biome? If common drivers exist, what are they? Are they abiotic or biotic, or both? The authors provide insights on broad, generalizable patterns that go beyond site-specific studies, and present discussions on factors such as varying temporal dynamics, latitudinal differences, human-caused vs. natural disturbances, and the role of invasive alien species. This book is a must-read for researchers and students in ecology, plant ecology, restoration ecology and conservation biology. It also provides a valuable framework to aid land managers attempting to manipulate successional recovery following increasingly intense and widespread human-made disturbances.

A Natural History of the Mojave Desert (Paperback): Lawrence R. Walker, Frederick H. Landau A Natural History of the Mojave Desert (Paperback)
Lawrence R. Walker, Frederick H. Landau
R874 R773 Discovery Miles 7 730 Save R101 (12%) Ships in 18 - 22 working days

The Mojave Desert has a rich natural history. Despite being sandwiched between the larger Great Basin and Sonoran Deserts, it has enough mountains, valleys, canyons, and playas for any eager explorer. Ancient and current waterways carve the bajadas and valley bottoms. This diverse topography gives rise to a multitude of habitats for plants and animals, many of which are found nowhere else in the world. A Natural History of the Mojave Desert explores how a combination of complex geology, varied geography, and changing climate has given rise to intriguing flora and fauna-including almost 3,000 plant species and about 380 terrestrial vertebrate animal species. Of these, one quarter of the plants and one sixth of the animals are endemic. The authors, who, combined, have spent more than six decades living in and observing the Mojave Desert, offer a scientifically insightful and personally observed understanding of the desert. They invite readers to understand how the Mojave Desert looks, sounds, feels, tastes, and smells. They prompt us to understand how humans have lived in this desert where scant vegetation and water have challenged humans, past and present. A Natural History of the Mojave Desert provides a lively and informed guide to understanding how life has adapted to the hidden riverbeds, huge salt flats, tiny wetlands, and windswept hills that characterize this iconic desert.
