Fire is pivotal to the functioning of ecosystems in Australia, affecting the distribution and abundance of the continent's unique and highly diverse range of plants and animals. Conservation of this natural biodiversity therefore requires a good understanding of scientific processes involved in the action of fire on the landscape. This book provides an up-to-date synthesis of current knowledge in this area and its application in contemporary land management. Central to the discussion is an exploration of the concept of the fire regime and its interactions with biodiversity.
Mediterranean-type ecosystems have provided ecologists with some of the most scientifically-rewarding opportunities to formulate and evaluate hypotheses about large and small-scale ecological phenomena. Comparison of mediterranean-type climate ecosystems in different parts of the world has not only permitted a strong test for ecological convergence, but also critical understanding of key ecophysiological and population processes.
Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.
Dry summer, wet winter climate? This is your must have plant guide. Selecting plants suited to your climate is the first step toward a thriving, largely self-sustaining garden that connects with and supports the natural world. With gentle and compelling text and stunning photographs of plants in garden settings, Gardening in Summer-Dry Climates by Nora Harlow and Saxon Holt is a guide to native and climate-adapted plants for summer-dry, winter-wet climates of North America's Pacific coast. Knowing what these climates share and how and why they differ, you can choose to make gardens that maintain and expand local and regional biodiversity, take little from the earth that is not returned, and welcome and accommodate the presence of wildlife. With global warming, it is now even more critical that we garden in tune with climate.
Here is a wonderful overview of the landscape and vegetation of the five regions of the world that have a Mediterranean climate. In addition to the Mediterranean Basin itself, this climate of mild, rainy winters and dry, warm summers is found in California and parts of Chile, South Africa, and Australia. 30 maps. 18 tables. 46 line illustrations. 75 color and 90 b&w photos.
As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book.Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.
Australian Vegetation has been an essential reference for students and researchers in botany, ecology and natural resource management for over 35 years. Now fully updated and with a new team of authors, the third edition presents the latest insights on the patterns and processes that shaped the vegetation of Australia. The first part of the book provides a synthesis of ecological processes that influence vegetation traits throughout the continent, using a new classification of vegetation. New chapters examine the influences of climate, soils, fire regimes, herbivores and aboriginal people on vegetation, in addition to completely revised chapters on evolutionary biogeography, quaternary vegetation history and alien plants. The book's second half presents detailed ecological portraits for each major vegetation type and offers data-rich perspectives and comparative analysis presented in tables, graphs, maps and colour illustrations. This authoritative book will inspire readers to learn and explore first-hand the vegetation of Australia.
This book will appeal to an international audience as well as be irresistible to local readers. Anyone working or with an interest in Australia’s arid zone should need ready access to this book. There is no equivalent publication out there at the moment, and this book has many authoritative chapters, richly illustrated with colourful material. The challenge of this book was to assemble current knowledge on particular topics and concepts, and principles relating to them. It is also forward-looking by identifying where there are gaps or inadequacies in knowledge, and where future research needs to be directed. Lead authors were encouraged to take such an approach; they had the opportunity to involve any author they considered appropriate. The final product shouldbe a fabulous resource, also for university courses, especially at MSc level.
