Morphological variability, taxonomy and ecology of Discostella pseudostelligera (Bacillariophyceae, Centrales) and similar species
The morphological study of 21 samples of the Discostella pseudostelligera from 19 lakes, reservoirs and rivers has shown a significant variability in the majority of quantitative (the valve diameter, size of central area, number of striae and marginal fultoportulae in 10μ m) and qualitative (the relief of central area and its structure, arrangement of marginal fultoportulae) morphological characteristics. The number of striae and marginal fultoportulae in 10μ m are the principal taxonomical characteristics (according to the coefficient of variation) among the quantitative features and the most variable are the valve diameter and the size of the central area. The obtained results allowed the author to extend the diagnosis of D. pseudostelligera, refer D. woltereckii and D. stelligeroides to its synonymy as well as specify the ecology and distribution of D. pseudostelligera.

More about this publication?
- Nova Hedwigia is an international journal publishing original, peer-reviewed papers on current issues of taxonomy, morphology, ultrastructure and ecology of all groups of cryptogamic plants, including cyanophytes/cyanobacteria and fungi. The half-tone plates in Nova Hedwigia are known for their high quality, which makes them especially suitable for the reproduction of photomicrographs and scanning and transmission electron micrographs.
