This study was undertaken to monitor the course of a secondary succession of phytoplankton in temporary water bodies, based on a man-made periodically drained pond. Results of phycological analyses showed, that small Chlorophyceae from the order Chlorococcales predominated qualitatively throughout the study period. Chlorophyceae, e.g. stress-resistant Haematococcus pluvialis, developed best as the first algae (after the pond was re-filled). In the next stages of diatom succession (Ulnaria ulna) predominated quantitatively, followed by the longest period of Cyanobacteria (Aphanothece elabens) predominance, replaced again by Chlorophyceae (Tetraëdron minimum and Oocystis lacustris). Total abundance of algae, similarly as that of Cyanobacteria, were positively correlated with temperature and pH of water.

This paper reports that selected low molecular hydrocarbons, i.e. hexane, cyclohexane and benzene added to cultures of the alga Scenedesmus obliquus (Chlorococcales), grown under auxotrophic and sterile conditions, inhibit the growth and stimulate the accumulation of cell wall carotenoids. The maternal cell walls contain: canthaxanthin, astaxanthin and its oxidation products, i.e. astacene and semiastacene, 2,3-didehydrofritschiellaxanthin and lutein. Samples of the cell walls obtained from homogenate also contain echinenone. The differences in cell wall carotenoids content of maternal cell walls and cell walls from homogenates of algal cells are discussed.

We present discoveries of internal bodies in problematic Silurian and Devonian organic−walled microfossils classified traditionally as polygonomorph, acanthomorph, sphaeromorph, and herkomorph acritarchs. These bodies are comparable with reproductive structures (autoand/or aplanospores) of modern unicellular green algae (Chlorococcales). Our findings suggest that many of these microfossils may represent asexually reproducing (sporulating) vegetative cells of chlorococcalean algae. The presence of spore−like bodies in the studied acritarchs supports earlier suggestions, based on ultrastructural and biomarker studies, that some acritarchs can be affined with green algae.
