Siliceous Chrysophycean Microfossils: Recent Advances and Applications to Paleoenvironmental Investigations
Published online by Cambridge University Press: 17 July 2017
Extract
Chrysophytes are a diverse group of algae, commonly known as the golden-brown algae (Bold and Wynne, 1978), and consist of two classes, the Chrysophyceae and Synurophyceae (Andersen, 1987). Over 800 species have been described (Kristiansen, 1990; Kristiansen and Takahashi, 1982; Preisig, 1995), and it is estimated that more than 1,000 species exist. Chrysophytes are distinguished from other algae on the basis of chloroplast type and structure, photosynthetic pigments, storage product, flagellar apparatus, and especially the production of a siliceous resting stage, called the stomatocyst, statospore, or cyst (Hibberd, 1976; Kristiansen, 1990; Kristiansen and Takahashi, 1982).
