Título: | Diversity and Distribution of Marine Microbial Eukaryotes in the Arctic Ocean and Adjacent Seas |
Autor: | Lovejoy, Connie; Massana, Ramon CSIC ORCID ; Pedrós-Alió, Carlos CSIC ORCID | Fecha de publicación: | may-2006 | Editor: | American Society for Microbiology | Citación: | Applied and Environmental Microbiology 72(5): 3085-3095 (2006) | Resumen: | We analyzed microbial eukaryote diversity in perennially cold arctic marine waters by using 18S rRNA gene clone libraries. Samples were collected during concurrent oceanographic missions to opposite sides of the Arctic Ocean Basin and encompassed five distinct water masses. Two deep water Arctic Ocean sites and the convergence of the Greenland, Norwegian, and Barents Seas were sampled from 28 August to 2 September 2002. An additional sample was obtained from the Beaufort Sea (Canada) in early October 2002. The ribotypes were diverse, with different communities among sites and between the upper mixed layer and just below the halocline. Eukaryotes from the remote Canada Basin contained new phylotypes belonging to the radiolarian orders Acantharea, Polycystinea, and Taxopodida. A novel group within the photosynthetic stramenopiles was also identified. One sample closest to the interior of the Canada Basin yielded only four major taxa, and all but two of the sequences recovered belonged to the polar diatom Fragilariopsis and a radiolarian. Overall, 42% of the sequences were <98% similar to any sequences in GenBank. Moreover, 15% of these were <95% similar to previously recovered sequences, which is indicative of endemic or undersampled taxa in the North Polar environment. The cold, stable Arctic Ocean is a threatened environment, and climate change could result in significant loss of global microbial biodiversity | Descripción: | 11 pages, 6 figures, 2 tables, supplemental material http://aem.asm.org/content/72/5/3085/suppl/DC1 | Versión del editor: | https://doi.org/10.1128/AEM.72.5.3085-3095.2006 | URI: | http://hdl.handle.net/10261/27470 | DOI: | 10.1128/AEM.72.5.3085-3095.2006 | ISSN: | 0099-2240 | E-ISSN: | 1098-5336 |
