Diatoma vulgaris | Diatom Flora of Britain and Ireland

For Diatoma species, Peng (2014) listed D. tenuis C. Agardh, D. moniliformis and D. vulgaris and provided a few illustrations. Recently, more new species from Lake Qinghai belonging to the genera Ctenophora (Grunow) Williams and Round, Die geschlechtliche Fortpflanzung erfolgt bei Diatoma durch Anisogamie, wobei pro Zelle zwei Gameten gebildet werden. Nach der Verschmelzung kommt es im Rahmen der Auxosporenbildung zur Zellvergrößerung. Dauerzellen können auch direkt aus vegetativen Zellen gebildet werden.

Compared to Diatoma tenuis, Diatoma kalakulensis is characterized by longer valves, higher stria density, wider apical ends and the position of its rimoportula. Valves elliptical to elliptical-lanceolate with broadly rounded subrostrate apices. Transapical costae visible under LM, striae not visible under LM.

Longer chain-like structures, as well as short planktonic colony forms, are observed in this species. Compare Diatoma tenuis is the most similar, but has linear valves with capitate apices. Diatoma vulgaris has wider and longer valves.

The Diatoms: A Brief Overview The diatoms are an amazing group of organisms, part of the Stremenopile lineage of life. These photosynthetic unicells (ranging from 1 µm to over 1 mm in size) have chlorophylls a and c, and a complement of accessory pigments that include xanthophylls and carotenoids, making the living cells golden-brown in color. They produce Cette petite espèce a ses segmens de forme quadrilatère, solitaires ou se tenant de deux à quatre enserable après leur disjonction, brunâtres vers le centre où plusieurs sont marqués de deux points ronds parfaitement transparens.
