Abstract

Many rivers in Ostholstein (Northern Germany) repeatedly cross lakes and reservoirs. This paper investigates how far structure and function of the bacterial populations of a small river change when the river flows through a lake. — During an annual cycle both bacteriological and hydrographic parameters were determined. It could be shown that the lake considerably affects quantity and function of the bacterial populations of the river: (i) the lake can dampen parameters of the river, a fluctuating input being opposed to a relatively constant output. This holds good for e. g. the saprophytes and the maximum uptake velocity for glucose; (ii) the lake can cause fluctuations, an even input being opposed to remarkable fluctuations at the outlet. This was especially shown for the total number of bacteria.
