Circumboreal diatom Navicula streckerae Lange-Bert. & Witk., especially on lineolae
Navicula streckerae was recorded in two locations of northern Germany and the Arctic Ocean. According to the findings of this taxon from Lake Khovsgol (Mongolia) and Kamchatka (Russia) by our investigations, this taxon distributed northward from latitude 50°N. on the Eurassian Continent and is consi...
