Originally published in 1986 this book presents an in-depth treatment of the biology of the chrysophytes. The papers collected here are a result of the First International Chrysophyte Symposium held at the University of North Dakota in 1953. The 'golden algae' a group of predominantly fresh water microorganisms have distinctive features that present much information about their taxonomic classification their place in evolution and their role in the environment. The ecological significance of the chrysophytes is evident from their abundance in acid bogs and lakes a condition that has created a new group of investigators concerned with these unique algae and the changing environment. These are just some of the aspects of chrysophyte biology that are discussed here. This book provides a strong foundation towards understanding today's living forms of chrysophyte algae and sheds light on the probable aquatic ecosystems of the past. Language: English
