Honouring English biologist Thomas Henry Huxley, (1825 – 1895), popularly known as Darwin’s Bulldog for his advocacy of Charles Darwin’s theory of evolution. You are using a version of browser that may not display all the features of this website. However, patches of bright water in satellite images are not always E. huxleyi blooms and satellite evidence needs to be verified by in situ sampling in the area. European register of marine species: a check-list of the marine species in Europe and a bibliography of guides to their identification. Emiliania huxleyi endures N-limitation with an efficient metabolic budgeting and effective ATP synthesis. Satellite images show that blooms can cover areas of more than 10,000 km$${\textstyle ^{2}}$$, with complementary shipboard measurements indicating that E. huxleyi is by far the dominant phytoplankton species under these conditions.

Emiliania huxleyi (Haptophyta) is the most ubiquitous and abundant coccolithophorid in modern oceans [ 2 ], and forms extensive coastal and mid-oceanic mesoscale blooms at temperate latitudes [ 3 ]. Emiliania huxleyi is a unicellular, calcifying microalga from the group of haptophyta (species of coccolithophorida) which, for example, is related to diatoms and brown algae. (2005). Threat status Europe: Not evaluated (IUCN) The EUNIS species component has very limited information about this species. (2008). World-wide electronic publication, National University of Ireland, Galway.. Marine viruses are major ecological and evolutionary drivers of microbial food webs regulating the fate of carbon in the ocean. Alkenones are used by earth scientists as a clue to past sea surface temperatures. There is currently only one species in this genus: Emiliania huxleyi virus 86 . Emiliania huxleyi, a key player in the global carbon cycle is one of the best studied coccolithophores with respect to biogeochemical cycles, climatology, and host-virus interactions.Strains of E. huxleyi show phenotypic plasticity regarding growth behaviour, light-response, calcification, acidification, and virus susceptibility.

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. 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. Emiliania huxleyi has the ability to fix inorganic carbon into both photosynthetic and biomineralized product. Liu, J.Y. (2001).

The morphological data given here can be used on the advanced search page. 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.
