География водорослей, вызывающих красное цветение снега в горных экосистемах

Abstract

The paper provides a literature overview about distribution of the red blooming of algae in snow and ice in various highlands of the world, the Arctic and Antarctica. The flowering of snow in the Urals mountainous country has been studied. The ecological characteristics of habitats and chemical parameters of the melt water were studied. The density of algal cells in samples reached 0,33 × 104 cells per ml-1. It was shown by morphological, ultrastructure and moleculargenetic studies that the red blooming of snow in the Subpolar Urals was caused by the green alga Chloromonas reticulata. The species is the plastic organism and has a wide distribution area from polluted water ponds to the Antarctic glaciers.
