Landslide Ecology (Hardcover, New): Lawrence R. Walker, Aaron B. Shiels Landslide Ecology (Hardcover, New)
Lawrence R. Walker, Aaron B. Shiels
R2,888 Discovery Miles 28 880 Ships in 12 - 17 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.

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
R1,251 Discovery Miles 12 510 Ships in 12 - 17 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.

Klaus Mehltreter, Lawrence R. Walker, Joanne M. Sharpe
R1,791 Discovery Miles 17 910 Ships in 12 - 17 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.

R1,379 R1,281 Discovery Miles 12 810 Save R98 (7%) Ships in 12 - 17 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.

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
R1,099 Discovery Miles 10 990 Ships in 12 - 17 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.

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)
Michael R Willig, Lawrence R. Walker
R3,705 Discovery Miles 37 050 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.
