Description
Summary:Diatoms are good indicators of trophic status and water quality. A water chemistry survey of 123 shallow artificial ponds in south-east England was conducted. Principal component analysis showed that phosphorus was an important variable. A subset of 31 ponds were used to examine the relationship between the surface-sediment diatom assemblages and water chemistry using canonical correspondence analysis. Annual mean total phosphorus was the most important variable in explaining the variance in the diatom species data. Weighted average regression and calibration were used to develop a diatom-phosphorus transfer function for the ponds. The model was applied to the fossil diatom assemblages in a sediment core from Marsworth reservoir, a hypertrophic lake in Hertfordshire. There are 61 references.
