Snow algae and other microorganisms are reported from green and orange snowpacks from New England during spring 1992 and 1993. Sites sampled include Mt. Katahdin and Sunday River Ski Area, Maine; Ashland, Hawley, Mt. Greylock and Wachusett Mtn. Ski Area, Massachusetts; Monadnock Mtn. And Mt. Washington, New Hampshire; Mansfield and Stowe Ski area, Vermont. Dominant snow algae belong to the green algal flagellate Chloromonas. Other microbes include snow fungi bacteria, ciliated protozoa, nematodes, rotifers and tardigrades. Laboratory cultures reveal several species of yellow-green algae and green algae not previously reported from snow in eastern North America. Two species of Chloromonas are newly discovered snow microbes, and one appears to be restricted to ski slopes. The distribution and diversity of snow microbes in eastern North America is greater than previously realized. New England isolates of Chloromonas will be used in laboratory studies to further our understanding of snow algal reproductive strategies and physiological ecology.
