DNA Metabarcoding Focusing on Eukaryote Communities on Langhovde Glacier, East Antarctica.

ABSTRACT: Ecological structures and habitats of eukaryote communities in supraglacial environments have attracted attention because of their unique biodiversity and potential impact on glacial surface melt. In this study, we investigated the microbial community on Langhovde Glacier in East Antarctica, wherein few molecular biological studies have been conducted. We performed a comprehensive environmental DNA analysis and dissolved ion measurements focusing on various types of supraglacial waters scattered on Langhovde Glacier, as well as ponds in the adjacent off-ice area. 18S rRNA gene analysis revealed the presence of diverse eukaryotic taxa on the glacier, including Chlorophyta, Chrysophyceae, Cercozoa, Choanoflagellatea and Streptophyta. Distinct ecological structures were observed between large
