A sediment trap was Emiliania – Latinized surname. 6.3.1 Emiliania huxleyi (Haptophyta, Coccolithophyceae, Isochrysidales) The calcified marine unicell, Emiliania huxleyi , is the most intensively studied member of the coccolithophorid microalgae, because (1) it is easily cultured and (2) it is the most abundant coccolithophore species in the ocean and can form massive blooms in temperate and subpolar regions, producing up to 10 8 cells L −1 ( Taylor et al., 2017 ). Emiliania huxleyi harbors a genome constituted by core genes plus genes distributed variably amongst strains, which supports a considerable intra-species variability . kleijneae Young & Westbrook ex L.K.Medlin & J.C.Green, 1996 This species has been an inspiration for James Lovelock's Gaia hypothesis which claims that living organisms collectively self-regulate biogeochemistry and climate at nonrandom metastable states. aurorae S.S.Cook & Hallegraeff, 2011 Variety Emiliania huxleyi var.

Scott, F.J.; Marchant, H.J. 115104  Coccoliths are formed within the cell in vesicles derived from the golgi body.When the coccolith is complete these vesicles fuse with the cell wall and the coccolith is exocytosed and incorporated in the coccosphere. an experiment that has been published in the scientific literature, an orthologous protein, a record from another database, etc.

Most of what is known about the distribution of blooms of Emiliania huxleyi comes from satellite evidence. The coccoliths are either dispersed following death and breakup of the coccosphere, or are shed continually by some species. Emiliania huxleyi.

There is currently only one species in this genus: Emiliania huxleyi virus 86 . ... Emiliania huxleyi, is a common constituent of phytoplankton assemblages from tropical to sub-polar oceans and is able to form large monospecific blooms up to the polar fronts . Emiliania huxleyi, a cosmopolitan coccolithophore in the modern ocean, plays an important role in the carbon cycle and local climate feedback as it can form extensive blooms, calcify, and produce dimethylsulfoniopropionate (DMSP) leading to the generation of dimethyl sulfide (DMS) which affects climate when oxidized in the atmosphere.

It is believed to have evolved approximately 270,000 years ago from the older genus Gephyrocapsa Kampter and became dominant in planktonic assemblages, and thus in the fossil record, approximately 70,000 years ago. Thus, we expect differences and similarities between E. huxleyi and P. carterae regarding calcium pools to provide clues about the common mechanisms that underlie coccolithogenesis. (Ed.). -.
