Biotope and biocenosis of cryoconite hole ecosystems on Ecology Glacier in the maritime Antarctic

Popis výsledku v původním jazyce

Despite recent great interest in glacier ecosystems in the continental Antarctic, little is known about their maritime counterparts. Our study presents descriptive data on cryoconite sediments and cryoconite holes on Ecology Glacier (King George Island) to accomplish three main objectives: (a) to identify main eukaryotic (algae, invertebrates) and prokaryotic (cyanobacteria) components of microbial communities, (b) to provide a baseline of community composition, organic matter and artificial contamination, and (c) to identify key abiotic factors that might be important in community assembly. Cryoconite holes were sampled along an altitudinal gradient of Ecology Glacier in January, mid Austral Summer 2017. Cryoconite holes located in lower altitude were deeper than those located in the middle and the highest altitude. Seventeen species of algae and cyanobacteria with biomass of 0,79 to 5,37 microg/cm3 have been found in sediments. Dominant species were cyanobacterial Pseudanabaena frigida and Bacillar
