| Abstract: | This study investigated the in situ productionof fungal biomass on presterilized woody substratessubmerged in natural estuarine and freshwater bodiesenriched with nitrogen and phosphorus-containingchemical compounds. Results suggest that themembrane-bound sterol ergosterol may hold significantpromise as an quantitative indicator of fungalresponse to water quality. We suggest that realisticassessment of the environmental health of naturalwaters should include a suite of bioassays that couldmeasure the response of living organisms to pollutionmuch more directly than could be predicted by current,indirect monitoring techniques. |
