A molecular survey of protist diversity through the central Arctic Ocean

The protist assemblage in the central Arctic Ocean is scarcely surveyed despite them being the major primary producers. Elucidating their response to changing environmental variables requires an a priori analysis of their current diversity, including abundant and rare species. In late summer 2011, s...

Description
Summary:The protist assemblage in the central Arctic Ocean is scarcely surveyed despite them being the major primary producers. Elucidating their response to changing environmental variables requires an a priori analysis of their current diversity, including abundant and rare species. In late summer 2011, samples were collected during the ARK-XXVI/3 expedition (RV Polarstern ) to study Arctic protist community structures, by implementation of automated ribosomal intergenic spacer analysis (ARISA) and 454-pyrosequencing. Protist assemblages were related to the hydrology and environmental variables (temperature, salinity, ice coverage, nitrate, phosphate, and silicate). The abundant (≥1 %) biosphere and rare (
