THE ACCLIMATED RESPONSE OF GROWTH, PHOTOSYNTHESIS, COMPOSITION, AND CARBON BALANCE TO TEMPERATURE IN THE PSYCHROPHILIC ICE DIATOM NITZSCHIA SERIATA 1
ABSTRACT Nitzschia seriata Cleve, a common member of marine bottom ice communities in the Arctic, was grown in unialgal batch cultures to test for compensatory mechanisms for the low temperatures (−1.8° C) typical of its natural habitat. The upper lethal limit for growth was between 12° and 15°C, an...
