Some aspects of thecal morphology in Ceratium hirundinella are redescribed by means of scanning electron microscopy. The internal anatomy of the cell has been clearly revealed for the first time in serial sections examined by transmission electron microscopy.

The internal anatomy of the cell has been clearly revealed for the first time in serial sections examined by transmission electron microscopy. Ceratium hirundinella.Ceratium hirundinella è un microrganismo acquatico che deve il nome al suo nuoto sinuoso ed aggraziato, come il volo di una rondine, un A study into the photophysiology, growth and migration of Ceratium hirundinella in Chaffey Reservoir in subtropical northern New South Wales, Australia, revealed that a proportion of cells formed subsurface accumulations at depths that optimized light intensity (212–552 μmol photons m –2 s –1) for photosynthesis and cell growth. 2.5 Ceratium hirundinella cell identi cation and enumeration Source water and treated water (1000 mL) samples were collected and ltered through 0.45 mm lter paper to trap C. hirundinella cells. Cells trapped on lter paper were recovered and re-suspended in 10 mL using a vortex mixer. Samples were.

The structure of the freshwater dinoflagellate Ceratium hirundinella is shown in Figure 1. Due to its distinct shape, the genus can be readily identified ( Janse van Vuuren et al. 2006 ). C. hirundinella cells are broadly or narrowly spindle-shaped, strongly dorsiventrally flattened when swimming with one anterior and three posterior horns when swimming ( Wetzel 2001 ; John et al. 2002 ; Janse

In our study, however, we found that the temporal occurrence ofC. hirundinella in Spanish reservoirs The horizontal distribution of Ceratium hirundinella (MULL.) BERGH was investigated in Lake Erken at ten stations in the summer of 1969.

Ceratium hirundinella Ceratium hirundinella is a species in Chromista (brown algae and allies) with 53 observations Ceratium cells are photosynthetic but also contain vacuoles that suggest phagotrophy. Aplanospores (no flagella) are common, often after blooms. C. hirundinella has angular spores that are uninucleate, thick walled, and packed with glycogen as a storage reserve.
