Présentation
Almost half the world is comprised of desert or dryland regions. Life in these harsh environments depends upon spectacular rivers that are constantly changing between states of flood and drought, but compared to the other rivers of the world, our knowledge of their ecology is limited. Ecology of Desert Rivers provides a comprehensive account of the variable ecology of these areas and how they determine the behaviour and composition of the organisms that survive in this ’boom and bust’ environment. It also covers how human interventions such as the creation of dams affect desert rivers and the animals and plants that depend on them for survival.
This book provides an up-to-date synthesis of all aspects of desert river ecology and will appeal to researchers and students in ecology, hydrology and geomorphology as well as conservation managers and policy-makers. Some of the world’s most catastrophic ecological disasters have occurred with water resource development (e.g. building of dams) on desert rivers. Knowledge of the long-term consequences is essential if we are going to avoid such disasters in the future. Some of the most spectacular ecosystems of the world are fed by desert rivers (e.g. Lake Eyre, Okavango Swamp, Nile delta), producing a vast array of life that depends on river flow.
Half the world is made up of dryland regions, yet we know relatively little about these areas and even less about their rivers. This book provides the most up to date understanding about the ecology of desert rivers and its dependence on generally unpredictable river flows.
