Photosynthetic activity of Arctic Vaucheria (Xanthophyceae) measured in microcosmos

open access: yesCzech Polar Reports, 2017
The xanthophycean alga Vaucheria inhabits very variable, and hence extreme, ecosys-tem of polar river estuaries. Therefore, it represents a unique system for the study of adaptation/acclimatization mechanisms. Since the ecophysiological measurements cannot be performed in the field directly, a piece of Vaucheria community collected in the Adventelva ...
