Significant glacier retreat has generated proglacial lagoons, some of which are open to the ocean. We used pyrotag sequencing of SSU rRNA genes and environmental data to characterize microorganisms from two pools adjacent to animal breeding areas, two glacial lagoons and Atlas Cove (marine site). The more abundant taxa included <i>Actinobacteria, Bacteroidetes</i> and <i>Proteobacteria</i>, ciliates and picoflagellates (e.g. <i>Micromonas</i>), and relatively few <i>Archaea</i>. Seal Pool, which is rich in organic matter, was characterized by a heterotrophic degradative community, while the less eutrophic Atlas Pool had more eucaryotic primary producers. Brown Lagoon, with the lowest nutrient levels, had <i>Eucarya</i> and <i>Bacteria</i> predicted to be oligotrophs, possess small cell sizes, and have the ability to metabolize organic matter. The marine influence on Winston Lagoon was evident by its salinity and the abundance of marine-like <i>Gammaproteobacteria</i>, while also lacking typical marine eucaryotes indicating the system was still functioning as a distinct niche. This is the first microbiology study of Heard Island and revealed that communities are distinct at each location and heavily influenced by local environmental factors.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Microbial communities of aquatic environments on Heard Island characterized by pyrotag sequencing and environmental data","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:32:18.654152","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-03-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000396122000001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/srep44480"},"refs":null,"anarec":{"AnaID":283985,"PubliDate":2017,"Pagination":"16 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"44480","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
