Oceanic round viruses, north to south and 4000 meters deep
The oceans contain almost 200,000 viral populations, depending on the last amount. The sea viruses were extended to 4,000 meters and North Pole. Although most do not harm humans, marine life can be contaminated, including whales and crustaceans.
And scientists only understand how these small organisms act in the marine life and chemistry.
Researchers from Ohio State University conducted a global map of marine viruses based on sea water based 80 sites around the world. The relationship between them is almost 12 times higher than the previous estimates.
The virus was surprised by their location and depth in only five groups.
"In each of these communities we examined the genes of viruses, we found genetic adaptation to different areas of the ocean," said Ann Gregory, from Belgium, KU Leuven.
The second surprise Arctic Ocean had different types of viruses. The point points for microbic diversity were thought to be an equator.
A liter of sea water usually includes millions of viruses; Most were not identified. In recent databases, 90% of populations can not be classified into a well-known group.
Knowledge of marine viruses is important because of the influence of other marine microbial bacteria and fungi.
Viruses have a great effect on small marine organisms, such as plankton, which produce more than half of the oxygen we breathe and absorb carbon dioxide from the atmosphere.
"Without microbes, the Earth, its oceans and even our human bodies remain," said Matthew Sullivan of Ohio State University. "Our laboratories eventually help researchers to" see the hidden viruses that infect these microbes ".
Research has been published in the Cell magazine. Most of the data comes from the Tara Ocean expedition (2009/2013) with Tara, using a 36 m aluminum vacuum saver.
