The diatoms are the most speciose group of algae, having global ecological significance in
the carbon and silicon cycles. They are almost unique among algae in being diplontic, and …

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 …

Due to limited morphological differentiation, diatoms can be very difficult to identify and
cryptic speciation is widespread. There is a need for a narrower species concept if …

Publisher Summary This chapter reviews the evolution of the diatoms and of various groups
within the diatoms and evaluates the significance of particular shared derived traits. The …

Variation of frustular morphology within the Achnanthidium minutissimum (Kütz.) Czarn.
species complex was studied in type populations of 12 described taxa and in 30 recent …

Recent studies have shown that the cosmopolitan diatom Skeletonema costatum sensu lato
is composed of several morphologically and genetically distinct species. To assess whether …

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 …

The identity and nomenclatural history of several smallcelled naviculoid taxa are revisited.
The species discussed here are important from the ecological point of view since they are …
