... species, including the S. suzukii group, S. vestibulis, S . cf. niagarae and S . cf. oregonicus , seem to respond slowly to climatic changes. Stratigraphic changes in the valve concentration of Stephanodiscus specimens that more or less resemble S. suzukii or S. vestibulis ( Pl. 1 ) are shown...

... indicator species such as Stephanodiscus niagarae , and the persistence of small, benthic fragilarioid taxa may be indicative of a shift from a warm and dry climate to a warm but somewhat wetter period, perhaps with an increase in turbidity (i.e., decreased light quality) and an initial increase in lake...

... diatom Stephanodiscus niagarae Ehrenberg, 1845 . S. niagarae represents a phenotypically irreducible cluster, but lacks any defining apomorphies, is entirely plesiomorphic, and geographically widespread. Because it is not monophyletic, Mishler and Theriot (2000) concluded that it was not a product...
