This article reviews current knowledge of wall morphogenesis in pennate diatoms in relation
to the way characters are defined and described for taxonomic and systematic analyses. It …

Recent morphometric and breeding studies of diatoms show that the present species
classification is too coarse and hides significant diversity. Many species are subdivided into …

Aim To study large‐scale patterns of benthic diatom assemblages in rivers, to assess the
relative importance of environmental and geographical factors affecting their composition …

Benthic algal communities are shaped by the availability of nutrients and light and by
herbivore consumption. Many studies have examined how one of these factors affects algal …

Over the years, there have been several attempts to compile diatom names (genus, species,
variety and form names) and the literature in which the names were proposed. This includes …

In spite of high species diversity and many years of study, most diatom life history strategies
remain unknown. Floristics, taxonomy, and applied studies continue to dominate scientific …

We review the literature on species flocks in diatoms. Past descriptions of species flocks in
diatoms are of few species and do not demonstrate monophyly of the taxa explicitly. The …

Diatom studies of French running waters over more than twenty-five years revealed the
recent appearance of a number of species which could not have been overlooked before …

Diatoms are considered unicellular eukaryotic organisms exclusively depositing biogenic
silica. Heretofore there has been no report of calcification by these algae. Here it is shown …

A cladistic analysis of eleven freshwater gomphonemoid diatom taxa yielded three equally
most parsimonious cladograms. The three cladograms suggest Gomphoneis Cleve is non …
