E, Biology and medical science}, month = {Jan}, note = {P(論文), Fifty-two taxa of microorganisms, including 20 taxa of diatoms, 7 of choanoflagellates, 5 of Paraphysomonas, and other 20 taxa, were determined from fixed and unfixed samples of the sea ice and lake water which were collected from a lagoon, Lake Saroma, Hokkaido in February 1979. The diatom population was dominantly distributed both in the sea ice and lake water, and Dunaliella sp. Gymnodinium sp. and Quadrichloris sp. Were relatively abundant in the sea ice. Forty-five taxa were found in the sea ice and 41 taxa of them were distributed in the bottom part. Twenty-nine taxa of microorganisms were found with the optical microscope, whereas other 23 taxa were identified by the electron microscope. Two taxa each of Paraphysomonas, Chrysochromulina and Pinaciophora, and 7 taxa of choanoflagellates are new to Japan.}, pages = {49--63}, title = {Floristic Study of Ice Algae in the Sea Ice of a Langoon,Lake Saroma,Hokkaido,Japan (Biology and Medical Science)}, volume = {34}, year = {1981} }
