Composition of the summer photosynthetic pico and nanoplankton communities in the Beaufort Sea assessed by T-RFLP and sequences of the 18S rRNA gene from flow cytometry sorted samples

Abstract: The composition of photosynthetic pico and nanoeukaryotes was investigated in the North East Pacific and the Arctic Ocean with special emphasis on the Beaufort Sea during the MALINA cruise in summer 2009. Photosynthetic populations were sorted using flow cytometry based on their size and pigment fluorescence. Diversity of the sorted photosynthetic eukaryotes was determined using terminal-restriction fragment length polymorphism analysis and cloning/sequencing of the 18S ribosomal RNA gene. Picoplankton was dom… Show more

“…(2003) and Booth and Horner (1997) for a phytoplankton assemblage dominated by < 5 µm sized cells observed in the central oligotrophic AO in summer (13-70 g g −1 , ∼ 30 g g −1 on average). Furthermore, these studies report abundant picophytoplankton ecotype Micromonas as observed during the Malina cruise (Balzano et al, 2012). DuRand et al (2002) measured Micromonas sp.…”

“…Over the growth season, the DCM progressively lowers the nitracline down to 60 m depth, where light becomes the limiting factor (Martin et al, 2010). On the slope of the Mackenzie Shelf, where waters were amongst the most oligotrophic sampled during the Malina cruise , picoplankton (Micromonas ecotype) and phytoplankton < 5 µm dominated respectively the surface and DCM autotrophic community (Balzano et al, 2012;Claustre and Ras, unpublished data) whose role is central in mediating carbon fluxes in summer (Li et al, 2009).…”

“…The cosmopolitan picophytoplankter Micromonas (Mamiellophyceae, Mamiellales) usually dominates the coastal eukaryotic phytoplankton communities from polar to tropical waters (Thomsen and Buck, 1998;Not et al, 2004;Foulon et al, 2008;Balzano et al, 2012;Monier et al, 2015). Members of this prominent genus are distributed in three discrete genetic clades (Guillou et al, 2004;Foulon et al, 2008) that are all susceptible to viral infection (Baudoux et al, 2015;Martínez-Martínez et al, 2015).…”

“…They are typical of coastal waters Romari and Vaulot, 2004;Collado-Fabri et al, 2011) where they can form sporadic blooms (O'Kelly et al, 2003) but have also been observed in open oceanic waters (Foulon et al, 2008;Monier et al, 2012;Treusch et al, 2012;Vaulot et al, 2012). The genus Micromonas can be dominant in Arctic ecosystems (Lovejoy et al, 2007;Balzano et al, 2012). Members of these three genera are easily isolated into cultures and genome sequences from representative strains are available (Derelle et al, 2006;Worden et al, 2009;Moreau et al, 2012), fostering their use as biological models for marine photosynthetic eukaryotes.…”
