Цианобактериальные маты как объекты мониторинга антарктических экосистем

Цианобактериальные маты как объекты мониторинга антарктических экосистем

Abstract

На территориях постоянно действующих научных станций и сезонных полевых баз Российской антарктической экспедицией (РАЭ) проведено изучение цианобактериальных матов (ЦБМ) как индикаторов антропогенного воздействия. Показано, что количество обнаруженных ЦБМ на загрязненных территориях (в результате антропогенной и орнитогенной нагрузки) заметно превышает их число на экологически чистых территориях Антарктики, а контаминация ЦБМ посторонней ми-кробиотой в нарушенных экосистемах возрастает в 1,5–3 раза. Обнаружение патогенных штаммов Yersinia enterocolitica, а также условно-патогенных псевдомонад и микромицетов в составе ЦБМ, формирующихся вблизи полярных станций, является основанием для создания системы экологического и эпидемиологического мониторинга в местах присутствия человека в Антарктике.

Cyanobacterial mats (CBM) in the territories of polar research stations and seasonal f eld 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.
