Spontaneous aggregations of flagellates are formed under the cover-glass because the organisms are attracted to and remain in regions where the concentration of dissolved oxygen is less than the saturation concentration under atmospheric partial pressure. These regions of lessened oxygen content arise towards the center of the liquid beneath the cover-glass, owing to the oxygen consumed by the ...

The fatty acid compositions of 5 freshwater heterotrophic flagellates were studied using laboratory cultures. The flagellates Bodo saltans, Paraphysomonas vestita, Spumella pudica, Polytoma uvella and Chilomonas paramecium were cultured on Synura medium enriched either with Régilait milk powder (MP medium; Régilait, St Martin Roche, France) or with Tabimin dry fish food (DFF medium; Tetra, Mell...

phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems alon...

The vast increase in the population density of the rumen flagellate Neocallimastix frontalis shortly after the host animal has commenced eating is caused by stimulation of a reproductive body on a vegetative phase of the organism to differentiate and liberate the flagellates. The stimulant is a component of the host's diet. The vegetative stage of N. frontalis bears a strong morphological resem...
