Temporary waters are found throughout the world and include intermittent streams and ponds, episodic rain puddles and seasonal limestone lakes. These natural bodies of water experience a recurrent dry phase of varying duration and spatial extent Uys and O Keeffe 1997 . Temporary waters are widespread in semi arid regions worldwide where they play an important role as water sources e.g., water supply, irrigation and hydroelectric power generation . Climate change represents an emerging problem for these ecosystems by increasing the frequency and duration of drought periods, with potentially important effects on fluvial biogeochemical processes.
