TAXONOMY AND ECOLOGY OF DIATOMS OF SURFACE SEDIMENTS OF UTAH LAKE, UTAH, U.S.

Diatoms in fifty-seven surface sediment samples from Utah Lake were examined. Three hundred and fifteen taxa in forty-three genera were identified and quantified. Statistical analyses of the data showed that distinct geographical subregions of the lake could be delineated according to population patterns of the bottom sediment diatoms. In particular, both Provo Bay and Goshen Bay were distinct from each other and from other areas of the lake.
