The pico-sized Mamiellophyceae and a novel Bathycoccusclade from the summer plankton of Russian Arctic Seas and adjacent waters
ABSTRACT Global climate changes and anthropogenic activity greatly impact Arctic marine biodiversity including phytoplankton which contribute greatly to atmospheric oxygen production. Thus the study of microalgae has rising topicality. Class Mamiellophyceae is an important component of phototrophic...
