Quality Assessments

Abstract This chapter, after a general introduction to quality assessments of freshwater habitats, reviews the use of freshwater nematodes as in situ bioindicators, including in monitoring the ecological quality of freshwater habitats. By drawing on studies of nematode communities in unpolluted and polluted habitats as examples, it highlights both the different methods used to assess the quality of freshwater ecosystems and their applications. A focus of the chapter is the development of a new index that uses freshwater nematodes to assess chemically induced changes in the ecological status of freshwater habitats, the NemaSPEAR[%]-index (Nematode SPEcies At Risk).

Induced Changes

1. Erythrocytes were incubated in buffers with different [bicarbonate]/[chloride] ratios. 2. The erythrocyte sodium content was higher in buffers with higher [bicarbonate]/ [chloride] ratios. 3. The rise in erythrocyte sodium concentration with increase in [bicarbonate]/[chloride] ratio was independent of the effects of ouabain and ouabain plus ethacrynic acid. Primaquine-induced changes in membrane permeability, ATP depletion by starvation and the use of potassium-free buffers did not change the effect. 4. The results may demonstrate a system which either increases the permeability of erythrocytes to sodium or regulates the sodium content of erythrocytes by a carrier system which is independent of ATP.
