Sampling sites and red-pigmented green algae causing red snow phenomena. a Map showing the locations of red-snow sampling sites. b Representative photograph of red snow on Harding Icefield in Alaska. c Microscopic view of the dominant snow algae contained in the red-snow samples. Scale bar, 20 µm. d An isolated cell of a red-snow alga used for single-cell PCR. To confirm that the sequences were obtained from red-snow algae, single cells from the red-snow samples were manipulated by micromanipulator system.
