Sažetak
Seasonal distribution and morphological changes in two forms of Ceratium hirundinella in the shallow karstic Mediterranean lakes, Ponikve and Njivice, during 1997/98 and 2000/01, were studied. C. hirundinella f. gracile was present during the whole investigation period in Lake Njivice. The same species was the dominant form in Ponikve Lake during 1997/98, while in 2000/01 a strong development of C. hirundinella f. austriacum occurred. The species C. hirundinella f. austriacum was restricted to spring-summer time. This population showed larger variations in number of horns. An analysis of morphometric measurements showed significant differences (p<0.01) in the total length of cells, length of fourth horn and V3 angle of the two Ceratium forms.
