Specimens with shorter frustules are more often found in the acidic water of bogs and ponds, while specimens with longer frustules are more likely to be found in oligotrophic to mesotrophic water.
The taxonomic study of the species was based on examination of the cells and frustules.
The frustule is not inert, and its complex of pores and chambers may play a significant role in nutrition.
Again, the average biovolume of each taxon was estimated by entering mean diatom measurements into geometric equations that best described the three-dimensional shape of the frustule (Gruendling 1971).
In some abalone species, it has been suggested that the dietary value for the juveniles differs among benthic diatom species, which have different morphologies, sizes, frustule strengths (Kawamura et al.
The average biovolume of each taxon was estimated by entering mean diatom measurements into geometric equations that best describe the three-dimensional shape of the frustule (Gruendling 1971).
The frustule itself can be fantastically ornate, covered in patterned ridges and pores in geometric designs.
Diatoms were scored as motile or nonmotile depending on the presence or absence of a track visible at either pole of the frustule.
The frustule of this species presents heavy silica deposition and robust constitution and it rarely would have been missed if present more frequently in samples from Lagoa dos Patos.
Diatomaceous earth (DE) is a material with sedimentary origin, basically constituted of skeletons or frustules, being friable, porous and fine.
