Both experiments and modeling are needed to quantify the potential biological impact of such effects, and the corollary potential of reflective blooms of other organisms to increase or reduce evaporation and methane evolution by altering fresh water temperatures. Benannt nach dem britischen Forscher Thomas Henry Huxley, ist Emiliania huxleyi der weltweit bedeutendste Vertreter der Coccolithophorida. Emiliania huxleyi, often abbreviated "EHUX", is a species of coccolithophore found in almost all ocean ecosystems the equator to sub-polar regions, and from nutrient rich upwelling zones to nutrient poor oligotrophic waters. 2012). Modeling Emiliania huxleyi – photosynthesis, calcification and the global CO2 increase 6 Thus far, efforts to model any aspect of coccolithophorids have been extremely limited. Bacterial membership of Emiliania huxleyi and Coccolithus pelagicus f. braarudii cultures was assessed using cultivation and cultivation-independent methods. Klebsormidium (2018) | dimethyl sulfide (DMS), which is of primary importance to the global sulfur budget and perhaps climate (HOLLIGAN, 1992). [5][7] It is the most numerically abundant and widespread coccolithophore species. Given the importance of coccolithophores, molecular and genetic tools for theses algae are relatively underdeveloped. A group of secondary metabolites known as polyketides that E. huxleyi synthesizes possess a wealth of pharmacologically important activities, including antimicrobial, antifungal, antiparasitic, antitumor and agrochemical properties. This is problematic because it is the surface water that exchanges heat with the atmosphere, and E. huxleyi blooms may tend to make the overall temperature of the water column dramatically cooler over longer time periods. The most common species is E. huxleyi, which is cosmopolitan in its distribution (RAYMONT, 1980) and commonly occurs in blooms during the summer in the subpolar regions of both the open North Atlantic ocean and continental It is believed to have evolved approximately 270,000 years ago from the older genus Gephyrocapsa Kampter[5][6] and became dominant in planktonic assemblages, and thus in the fossil record, approximately 70,000 years ago. It is studied for the extensive blooms it forms in nutrient-depleted waters after the reformation of the summer thermocline. Emiliania huxleyi wird von Viren der Spezies Emiliania huxleyi virus 86 aus der Gattung Coccolithovirus parasitiert. As with all phytoplankton, primary production of E. huxleyi through photosynthesis is a sink of carbon dioxide. Among coccolithophorids, Emiliania huxleyi is the most prolific, forming massive blooms that affect the global environment. "Bioconcentration mechanism of selenium by a coccolithophorid, "Pan genome of the phytoplankton Emiliania underpins its global distribution", Cocco Express - Coccolithophorids Expressed Sequence Tags (EST) & Microarray Database. Despite their importance, the bacterial diversity associated with these algae has not been explored for ecological or biotechnological reasons. Sie kommt von den Polargebieten bis zum Äquator weltweit vor und ist eine Schlüsselspezies im Ökosystem Ozean. E. huxleyi … Emiliania huxleyi (Lohman) Hay & Mohler is a cosmopolitan, coccolithophorid haptophyte known to form dense annual blooms, with reported concentrations ranging from 106 to 108 cells per mL [1,2]. This is due to the mass of coccoliths reflecting the incoming sunlight back out of the water, allowing the extent of E. huxleyi blooms to be distinguished in fine detail. Nanninga HJ, Tyrrell T (1996) Importance of light for the formation of algal blooms by Emiliania huxleyi. Changing the angle between the incident light and an applied magnetic field causes differences in the light-scattering intensities of a suspension of coccoliths isolated from Emiliania huxleyi. Emiliania huxleyi was named after Thomas Huxley and Cesare Emiliani, who were the first to examine sea-bottom sediment and discover the coccoliths within it.
