Opis

Chrysophytes are beautiful and delicate organisms living mostly in freshwater. They are pivotal for studies of protistan evolution, studies of food web dynamics in oligotrophic freshwater ecosystems, and for assessment of environmental degradation resulting from eutrophication and acid rain. They also represent excellent model cellular systems for studying processes inherent in basic metabolism, biomineralization, endo- and exocytosis and macro-assembly of cell surface layers. This book gives a broad overview of chrysophytes and contains chapters by leading experts organized under the themes of phylogeny, systematics and evolution; development, physiology, and nutrition; and ecology, paleoecology, and reproduction. The book contains major contributions towards a reorganization of chrysophyte systematics, plus comprehensive reviews of chrysophyte basic metabolism, biomineralization and siliceous scale deposition, ecology, paleoecology, and a history of chrysophyte research. Contributors present reviews of the literature in their particular area and also present ideas for future research.
