This also applies to the unpigmented smallest eukaryotes in planktonic systems, the heterotrophic flagellates (HFs), which form a diverse collection of tiny flagellated cells that are important agents in prokaryotic mortality through grazing and crucial in nutrient remineralization. The knowledge we currently have about the species forming HF assemblages is still fragmented, based on scattered molecular surveys and on a handful of cultured species, whose ecological relevance is unclear due to a prevalent culturing bias. In this presentation I will take advantage of recent extensive sampling datasets and high-throughput sequencing tools to investigate the diversity of HF to an unprecedented level. In particular, I will process a global sampling effort done in the major oceans during the Malaspina expedition, and the samples from a long-term temporal survey performed at the Blanes Bay Microbial Observatory. Metabarcoding of the V4 region of the rDNA in these samples covering relevant spatial and temporal scales will provide exhaustive taxonomic lists, which will be investigated for the presence of signatures corresponding to HF cells. The combination of powerful analytic tools and extensive sampling efforts allows, for the first time, a global study to identify the dominant HF species and better define their ecological relevance in the marine environment Peer Reviewed 2018-11-02T09:41:50Z 2018-11-02T09:41:50Z 2016-08-22 2018-11-02T09:41:50Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 16th International Symposium on Microbial Ecology (2016) http://hdl.handle.net/10261/171803 https://www.isme-microbes.org/field_collection_item/13 Sí none
