The number of extant species of diatoms is estimated here to be at least 30,000 and
probably ca. 100,000, by extrapolation from an eclectic sample of genera and species …

Diatoms are a very diverse group of microalgae that encompass about 100 000 taxa. This
makes an excellent bioindicator especially of rivers. The majority of biotic indices based on …

Diatoms are a diverse lineage with species that can be difficult to identify or cryptic, but DNA
barcoding, a molecular technique, can assist identification and facilitate studies of speciation …

This paper provides a step-by-step guide for the morphological analysis of corolla and the
decomposition of corolla shape variation into its symmetric and asymmetric components …

Diatom cultures of the G. parvulum species complex were established from seven different
sites in the Faroe Islands, Sweden, Germany, Mexico and Korea, and were studied in detail …

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 …

A listing of the accepted freshwater diatom genera worldwide is presented, indicating the
distribution of the genera by continent. Out of a total of 249 genera, 63 (25%) of those …

Unicellular algae and diatoms (Bacillariophyta) in particular, have attracted increasing
attention as the objects of biotechnology. Diatoms are known to produce …

Diatoms are the largest group of microalgae, play an enormous role in the biosphere, and
have major significance as bioindicators. Traditional identification requires inter alia long …

The Gomphonema parvulum complex includes species displaying considerable
morphological variability and a wide geographical distribution. These characteristics make …
