Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi, can grow without consuming vitamin B1 (thiamine), researchers have discovered.
A year-long experiment on tiny ocean organisms called coccolithophores suggests that the single-celled algae may still be able to grow their calcified shells even as oceans grow warmer and more acidic in Earth's near future.
Researchers have sequenced the genome of Emiliania huxleyi ("Ehux"), a species of single-celled photosynthetic marine algae that they say is responsible for removing carbon dioxide from the air, supplying the oxygen we breath, and even forming the basis of marine food chains.
Sorting through the vast amounts of genetic data from the Black Sea sediment record, Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was astounded by the variety of past plankton species that left behind their genetic makeup.
Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems.
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago.
Sediments buried beneath the Black Sea contain ancient virus and host DNA.
A study led by Dr Stuart Painter of the National Oceanography Centre helps explain the formation of huge phytoplankton blooms off the southeast coast of South America during the austral summer (December-January).
Lack of sufficient iron may be a significant factor in controlling massive blooms of Emiliania huxleyi, a globally important species of marine algae or phytoplankton.
Coccolithovirus, a giant double-stranded DNA virus, infects Emiliania huxleyi, a species of coccolithophore. The virus was first observed in 1999 by W.H. Wilson and his team at the Marine Biological Association. It was sequenced for the EhV-86 strain during the summer of 2005, and was found to be a "giant-virus" having 472 protein-coding genes. It is the largest known marine virus by genome.
