Cazaubon 1 Many freshwater algae are parasitized by aquatic fungi belonging to the Chytridiales Order. Given the high diversity among diatoms, we studied the two marine model diatoms—Thalassiosira pseudonana and Phaeodactylum tricornutum, a freshwater diatom, Asterionella formosa, and Navicula pelliculosa—found in fresh- and sea-water environments. Columnar incubators 4 m in height, held at 4 C, with a light gradient of 250 10 m mol photons m -2 sec -1 were used to simulate vertical mixing as found in Lake Michigan. In girdle view cells expand towards both ends of the valve. References are given in chronological order. Cambridge University Press, Cambridge. Figure 8.5 Competition between diatoms. In order to explain differences in the growth and reproduction of Daphnia pulicaria fed various freshwater diatoms, we measured ingestion rates and carbon incorporation for six cultured diatom species: the single-celled Stephanodiscus hantzschii, Stephanodiscus minutulus and Cyclotella meneghiniana, and the colony-forming Asterionella formosa, Fragilaria capucina and Fragilaria sp. 3. 17 : 47-58.

Variability in sinking rate of the freshwater diatom. (a) Asterionella formosa, when grown alone in a culture flask, establishes a stable population and maintains a resource, silicate, at a constant low level. Shape Cells linear and bilobate in valve view, with a larger, spatulate 'head pole' and a smaller spatulate 'foot pole'. The sinking rates of colonies of a laboratory strain of Asterionella formosa were measured over a 5-year period, during which time mean cell length and cell volume reduced by almost an order of magnitude and the typical, stellate arrangement of eight-celled colonies was eventually lost. The Diatoms. nov. from Lake Hovsgol, Mongolia. A. formosa is better able to grow at low PO4‐P concentrations than C. meneghiniana, as shown by its lower K for PO4‐P limited growth. Phylogenetic analyses based on 18S, 5.8S, and 28S ribosomal DNAs (rDNAs) revealed that this strain belongs to the recently described clade SW-I within the Lobulomycetales.

Asterionella fibula (Breb., 1849) Hustedt, 1952 Species: Asterionella formosa Hass. Asterionella Hassall (Heterokontophyta, Bacillariophyceae), taxonomic history and quantitative methods as an aid to valve shape differentiation. 1990).

Centrales, Fragilariaceae, Eunotiaceae. The top-down effects of parasi-tism result in … diatom species (Cyclostephanos dubius, Cyclotella rhomboideo-elliptica, Asterionella formosa, and Cyclotella ocellata) for more than 20,000 years, since the climate amelioration at the end of Last Glacial Maximum (LGM) (Wang et al., 2014).
