Stoermer, Eugene F., Edlund, Mark B., Pilskaln, Cynthia H., Schelske, Claire L.
Examination of surficial sediments at 16 stations shows minor, but consistent differences in the numbers and kinds of siliceous microfossils deposited in different regions of Lake Baikal. There is a...
Freshwater gomphonemoid diatom phylogeny: preliminary results (1993)
Kociolek, J.P., Stoermer, Eugene F.
A cladistic analysis of eleven freshwater gomphonemoid diatom taxa yielded three equally most parsimonious cladograms. The three cladograms suggest Gomphoneis Cleve is non-monophyletic as originally...
Evaluating diatom succession: some pecularities of the Great Lakes case (1993)
Succession of diatom communities in the Laurentian Great Lakes has several unusual aspects related to physical and chemical characteristics peculiar to these large systems and the constraints these...
Resting spores of the freshwater diatoms Acanthoceras and Urosolenia (1993)
Edlund, Mark B., Stoermer, Eugene F.
Diatom resting spores are a widespread, but sometimes misconstrued component of siliceous microfossil assemblages. We illustrate and discuss resting spore morphology found in populations of...
SEPARATING TABELLARIA (BACILLARIOPHYCEAE) SHAPE GROUPS BASED ON FOURIER DESCRIPTORS 1 (1992)
Mou, Daiqing, Stoermer, Eugene F .
A random sample of 490 Tabellaria specimens was analyzed using the harmonic amplitudes of the Fourier transformations of their valve outlines as shape descriptors. Principal component analysis (PCA)...
Bourne, Carol M ., Palmer, Jeffrey D ., Stoermer, Eugene F .
We constructed a complete physical map and a partial gene map of the chloroplast genome of Cyclotella meneghiniana KÜtzing clone 1020-1a (Bacillariophyceae). The 128-kb circular molecule contains a...
