spelling Heterogeneous archaeal communities in the particle-rich environment of an arctic shelf ecosystemGaland, Pierre E.Lovejoy, ConniePouliot, J.Vincent, Warwick F.ArcticBeaufort SeaArchaeaMicrobial diversityParticles9 páginas, 4 figuras, 2 tablas.We evaluated the phylogenetic diversity of particle-associated and free-living archaeal assemblages from the Mackenzie River and Beaufort Sea in the western Canadian Arctic. The physico-chemical characteristics of the water separated the sampling sites into three groups: riverine, coastal and marine water, which had strikingly different archaealcommunities. The riverine water was characterised by the presence of Euryarchaeota mainly belonging to the LDS and RC-V clusters. The coastal water was also dominated by Euryarchaeota but they were mostly affiliated to Group II.a. The marine waters contained most exclusively Crenarchaeota belonging to the Marine Group I.1a. The results suggest that Euryarchaeota in the coastal surface layer are associated with particle-rich waters, while Crenarchaeota are more characteristic of Arctic Ocean waters that have been less influenced by riverine inputs. The particle-associated communities were similar to the free-living ones at the riverine and marine sites but differed from each other at the coastal site in terms of the presence or absence of some taxonomic groups in one of the fractions, or differences in the proportion of the phylogenetic groups. However, there was no specific archaeal group that was exclusively restricted to the free-living or particle fraction, and the diversity of the particle-associated archaeal assemblages did not significantly differ from the diversity of the free-living communities.Financial support for this study was provided by the Natural Sciences and Engineering Research Council of Canada (NSERC), the Canada Research Chair program, Fonds québécois de recherche sur la nature et les technologies (FQRNT) and Indian and Northern Affairs Canada.Peer reviewedElsevier201220122008info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/58762reponame:DIGITAL.CSIC.
