Abstract

Provides an introduction to the physical geography of the Carpathian Basin and describes the nature of the shallow Hungarian Lake Balaton - its geology and glacial history; morphometry; cultural history; annual physical and chemical cycles; biological limnology; and interactions between various trophic levels. The water column is homogeneous; frequent stirring up of mud militates against stagnation or stable thermal stratification. Positive feedback mechanisms appear to exist among the dissolved salts-bacteria-primary producers, resulting in a reduced transfer of energy to secondary producers and fishes. Production of organic matter shows some cyclicity, but as a result of intensive metabolism and significant mineralization in the lake, the periodicity of annual physicochemical cycles is less distinct in space and time. Interspecific competition from introduced species (eel Anguilla anguilla and silver carp Hypophthalmichthys molitrix) has increased, and the food chain and energy pathways have been modified. There are also problems of cultural eutrophication and input of pesticides and other pollutants. -P.J.Jarvis
