Sommario/riassunto

As pressures on Australia's inland waters intensify from population growth, expanding resource development and climate change, there is an urgent need to manage and protect these special areas. Understanding their ecology underpins their wise management and conservation.  Australian Freshwater Ecology vividly describes the physical, chemical and biological features of wetlands, lakes, streams, rivers and groundwaters in Australia.  It presents the principles of aquatic ecology linked to practical management and conservation, and explains the causes, mechanisms, effects and manag
