Beschreibung
Droughts are a major hazard to both natural and human-dominatedenvironments and those, especially of long duration and highintensity, can be highly damaging and leave long-lasting effects.This book describes the climatic conditions that give rise todroughts, and their various forms and chief attributes. Pastdroughts are described including those that had severe impacts onhuman societies. As a disturbance, droughts can be thought of as"ramps" in that they usually build slowly and take timeto become evident. As precipitation is reduced, flows fromcatchments into aquatic systems decline. As water declines in waterbodies, ecological processes are changed and the biota can bedrastically reduced, though species and populations may survive byusing refuges. Recovery from drought varies in both rates andin degrees of completeness and may be a function of both refugeavailability and connectivity.
For the first time, this book reviews the available ratherscattered literature on the impacts of drought on the flora, faunaand ecological processes of aquatic ecosystems ranging from smallponds to lakes and from streams to estuaries. The effects ofdrought on the biota of standing waters and flowing waters and oftemporary waters and perennial systems are described and compared.In addition, the ways in which human activity can exacerbatedroughts are outlined. In many parts of the world especially in themid latitudes, global warming may result in increases in theduration and intensity of droughts.
Drought and Aquatic Ecosystems is essential reading forfreshwater ecologists, water resource managers and advancedstudents.

"This book provides a valuable source of information forboth freshwater ecologists and resource managers." (Bulletin of the British Ecological Society, 1 June2012)
"However, the extensive review of the global literature,combined with the thorough discussions of drought-related conceptsand definitions, make this book useful for those working in aquaticecosystems worldwide." (Austral Ecology, 1November 2012)
"It is balanced across taxa, habitat, and continents, andprovides insightful ideas to guide future research. As such,it is an important contribution to aquatic science that is wellworth the read." (Society for FreshwaterScience, 1 July 2012)
"Summing Up: Recommended. Upper-divisionundergraduates and above." (Choice, 1 March2012)
"Overall, it proves extremely useful to bring together thematerial in the core chapters with the fairly extensive contextualmaterial in the surrounding chapters; no doubt this will benefitmany researchers needing an introduction to this topic. There is nodoubt that this book will be read widely and will likely provide abasis and impetus for numerous future researchprojects." (Freshwater Biology, 1 September2012)
"This book is a major synthesis of what is known aboutdrought and aquatic systems. It is balanced across taxa, habitat,and continents, and provides insightful ideas to guide futureresearch. As such, it is an important contribution to aquaticscience that is well worth the read." (FreshwaterScience, 16 July 2012)
