Notes
A survey of the littoral rotifer fauna of the Bay of Quinte was completed during the ice-free period at five stations in 1985. The seasonal succession of the total rotifer population at each of the five stations, the timing of occurrence, and the quantity of individual species reflects and corroborates the known trophic status of these stations. Quantitative changes in the rotifer assemblage of the eight dominant species were evaluated for all five stations at five times during the year, and were also found to reflect trophic status. It was shown by the use of Detrended Correspondence Analysis and cluster analysis of the species/station matrix that rotifer assemblages and species combinations are capable of distinguishing between basins of the Bay of Quinte showing different trophy. Using the same statistical techniques, the total rotifer population of all station/times can be analysed, and provides a species ordination by trophic and temperature preference. The combination of Detrended Correspondence Analysis and cluster analysis as a recommended tool in numerical ecology was shown to be useful. Several remarkable species were found, and their taxonomy and autecology is discussed.
