Abstract

The distribution of Corixidae in stable habitats (lakes) has been shown to be related to a series of environmental parameters, for example major ion concentrations and the accumulation of vegetation and organic matter. (Macan 1954; Savage 1982, 1989). It is considered that similar ecological relationships probably occur in potentially unstable habitats. It appears that they may be utilised as biological indicators of water quality and for the monitoring of changing water quality in relation to both eutrophication and acidification. (Henrikson and Oscarson 1985; Jansson 1987). This supposition is discussed in relation to a number of environmental parameters, primarily conductivity (as a summation of major ion and nutrient concentrations), and the accumulation of organic matter and vegetation. It was found that corixids are unable to act as accurate biological indicator due to a poor understanding of their autecology and extensive overlapping of their ecological requirements. A possible application is discussed as by ordination they have the potential to act as marker species of unusual habitats in a geographical region.
