Cyanobacterial mats as objects of Antarctic ecosystem monitoring
Cyanobacterial mats (CBM) in the territories of polar research stations and seasonal field bases of the Russian Antarctic Expedition (RAE) were studied as indicators of human impact. It is shown that the number of detected CBM in the contaminated territories (from human and ornithogenic load) greatly exceeds the number in ecologically clean regions of the Antarctic, and the contamination of CBM by outside microbiota in disturbed ecosystems increases by 1,5–3 times. Detection of pathogenic strains of Yersinia enterocolitica as well as opportunistic pseudomonads and micromycetes in the CBM which are formed near the polar stations is the basis for the ecological and epidemiological monitoring in areas of human presence in Antarctica.
