About: Snow algae

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Snow algae are a group of freshwater micro-algae which grow in the alpine and polar regions of the earth. These algae have been observed to come in a variety of colors associated with both the individual species, stage of life or topography/geography. This variation is associated with both albedo differences of the snowy habitat and the presence of micro-invertebrates. Snow algae play a critical role in the trophic organization as primary producers who in turn are consumed primarily by tardigrades and rotifers. Snow algae have also been found to travel great distances being carried by winds.

  • 氷雪藻(ひょうせつそう)もしくは雪上藻(せつじょうそう、snow algae)とは、高山帯や極圏の夏季において雪や氷上に生育する低温耐性の藻類のことである。可視的なまでに広がった氷雪藻のコロニーは、藻類が持つ色素の種類により雪を赤、緑、黄色など様々な色に彩り、彩雪(現象)や雪の華などと呼ばれる現象を引き起こす。特に赤く色づくものを赤雪や紅雪、英語では微かなスイカの香りがするとして "watermelon snow" と呼ぶ。このような低温環境の極限環境微生物は、氷河を取り巻く生態系の理解に関連して研究対象となっている。 (ja)
