Among most diatom species, this leads to mean cell size diminution in the population (MacDonald, 1869;Pfitzer, 1869), and the maximum size of cells in a population is restored by auxosporulation followed by initial cell development. Normally, cell size restoration is achieved as a result of sexual reproduction, but vegetative enlargement has also been observed in some cases (Geitler, 1935;Round et al., 1990;Mann, 1993Mann, , 2011Chepurnov and Roshchin, 1995;Kaczmarska et al., 2013). ...
