Morphology, taxonomy, and distribution of selected diatom species of Thalassiosira Cleve in the Gulf of Mexico and Antarctic waters.
189 p., Dissertation Cultures of marine phytoplankton have increasing value in morphological and taxonomic studies. Fifteen species of Thalassiosira have been studied from culture and field samples in both light and scanning electron microscopes, revealing consistent patterns that may be in identifi...
