Sharks could lose a third of habitat in the North Pacific

Global warming will lead to a reduction of 35% where sharks in the North Pacific Ocean, at the same time, albatross and tuna have the opportunity to increase their "possession," according to an article published in the journal Nature Climate Change.

A team of U.S. and Canadian researchers led by Elliott Hazen (Elliott L.Hazen) from the National Oceanic and Atmospheric Administration of the USA (NOAA) compared the observations of the migration of 23 species of marine life with climate change projections to 2100.

"We assume that 35% of habitats of these species in the North Pacific to change. Mako sharks, salmon and blue sharks lose up to 35% of their habitat, as well as blue-headed whales and turtles. Increase by 10-30%" ownership " species such as the black-footed albatross, sooty shearwater and albacore tuna, "- says the article.

Cause changes in habitat of sea creatures, scientists explain how, migration corridors will shift and change in the amount of nutrients in the water.

For such "conservative" in the migration of species, such as sharks and whales, such changes may lead to a reduction in their numbers. For example, the rich food for predators polar waters will shift a thousand miles to the north, so that predators will have to overcome the extra distance in pursuit of prey. At the same time, mobile tuna and albatross receive additional territory.

According to the scientists, their research will help determine the long-term measures for the conservation of marine life.
