Stichochrysis immobilis is a diatom, not a chrysophyte
The samples were examined for siliceous microfossils, including diatoms, testate amoebae (Rhizopoda), and chrysophyte
Green and chrysophyte
algae of sizes smaller than 20 [micro]m were the most abundant in the stomach content analysis of the fishes Argyrodiaptomus furcatus and Notodiaptomus iheringi, therefore algae were considered as an important source of food for these species in a reservoir at south-eastern Brazil (Rietzler et al.
Morphological alterations in diatoms and chrysophyte
spores were recorded and analyzed.
Similarly growth and cell yields of the marine Chrysophyte
Aureococcus anophagefferens are stimulated in the presence of Selenite .
Ultrastructure of a marine dinoflagellate, Peridinium quinquecorne Abe (Peridiniales) from South Africa with particular reference to its chrysophyte
cysts were enumerated as separate categories during microscopy and the ratio comparing cysts and all microfossils was calculated.
Traditionally, these kills were attributed to high salinities or pollution from oil field activities, but, more recently, toxins released during blooms of a chrysophyte
alga (Prymnesium parvum) have been implicated (James and De La Cruz 1989; Rhodes and Hubbs 1992).
A minimum of 350 diatom valves per sample were counted on random transects, and the number of microspheres and chrysophyte
cysts per 350 diatom valves was recorded.
cysts were counted as separate categories under microscope and the ratio of chrysophycean cysts to diatoms was calculated.
The majority of chrysophyte
genera lack a covering of siliceous scales and exhibit a great plasticity in regard to both morphology and nutrition (Hoek et al.
