LOADING Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. However, it is not a legal authority for statutory or regulatory purposes. While every effort has been made to provide the most Ceratium hirundinella. Ceratium species are characterized by their horns and two flagella located in the transverse and longitudinal positions.

A similar case was described by Gálvez et al. (1988) in the La Concepción reservoir, southern Spain where Ceratium hirundinella was found to dominate in the DCM that occurred in the metalimnion and received 1-3% of surface incident light. 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.

Abstract. The dynamics of the Ceratium hirundinella population and the abundance of dinocysts in the plankton and sediments were studied in Lake Sempach in 1988. In 1987, a rich population of Ceratium (380 cells ml −1) accompanied by Peridinium spp. developed in the lake. The dinocysts were found entrapped in a kind of flocs, in the deepest part of the lake, in the upper flocculent layer.

Get premium, high resolution news photos at Getty Images Large populations of the dinoflagellate Ceratium hirundinella occur regularly in a small productive lake and their decline during September and October is normally associated with mass encystment. Evidence for the major role of benthic cysts in providing the inoculum for subsequent growth is given from morphological and quantitative studies over two contrasting years of cyst production, 1980 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 SUMMARY Some aspects of thecal morphology in Ceratium hirundinella are redescribed by means of scanning electron microscopy.
