Diversity, ecology and community structure of the freshwater littoral diatom flora from Petuniabukta (Spitsbergen)
Abstract: Despite the frequent application of diatoms in palaeoecological research in the High Arctic, our knowledge concerning the diversity, ecology, community associations, community dynamics and survival strategies of High Arctic freshwater littoral diatom floras is still rather limited. In the...
