In 2013, the starfish – the star of the morning sun, including the rich hued ochwith the new star and the star sun, whose bodies can be four meters long – the millions of the Pacific coast began to travel from Mexico to Alaska.
They were losing their illness. Injuries started with white limbs, destroying the surrounding flesh, loss of body, and finally death. As it is not understood, the problem would be examined.
One day, before the epidemic, Drew Harvell, a professor of evolutionary ecology and biology at the Cornell University, was listening to the illness, he received a strange letter.
"A group of Arkansas students received $ 400 check-in," said Dr. Harvell. "These kids really liked the idea of starfish that had disappeared from the seas, and they took the greatest amount of money, and we spent $ 400 to help our research. I've never done that anymore. They've done just that."
Dr. Harvell agrees with his money, and a lender dropped a bit more. "That has been established in our early survey," he said. "These children, none of them were from the Pacific, but they just needed to know what the stars were."
One of the best gifts for children's donations, A paper published by Wednesday's Science Advance magazine, also known as Starfish, has been published. Main Suspect: our warming oceans.
In 2013, parts of the Pacific Ocean became an unusually hot wave due to a wider wave of the sea heat, called Blob, which lasted for 2015 and worsened as a result of human warming. But while the ocean was warmed up, it was not evenly warmed up, which means that the heat waves are helping the starving dead.
In the study, Dr. Harvell and his colleagues use reports citizen scientistsThe ocean ocean samples collected by the National Oceanic Atmosphere and the Atmospheric Administration, when changes to the eastern starfles occurred when changes in the ocean temperature occurred.
While the disease caused about 20 star species, the researchers focused on starlings, mainly because they hit and there was good historical data before the epidemic.
The researchers found that killing the sun's star combines the heat pattern through the ocean.
Rebecca Vega Thurber, an associate professor of environmental microbiology at Oregon State University, did not participate in the study. "What is the great correspondence about this exciting piece of paper? The strong correspondence between temperature anomalies that happened in that year is that the sea stars began to die."
When everything went hot, a star star was sick and killed.
The study showed a correlation between the warming temperature and the spread of the disease, not the direct cause. But the hypothetical corroboration was initially challenged Researchers are also responsible for viruses in healthy starfish.
"For this reason, in this paper, it also seems to be a temperature," said Dr. Vega Thurber.
Dr. Vega Thurber pointed to a The particular pathogen does not necessarily mean the disease will develop.
For example, if you were a chicken, you're doing a shingles virus. Approximately, one third of carriers will develop the disease, but two thirds will not be able to. Starts to start something.
He has also caused heat dissipation of fungal populations and coral diseases in many parts of the world. In fact, when corals soften algae somewhat symbiosis or cause ocean warming, the disease usually dies.
There is something to help marine life, Dr. Harvell said. We can revive it seagrass Protecting beds and mangroves, for example. But, after all, we must stop the climate change, he said. More than the world's oceans have been absorbed 90% of the heat atmospheric humans release greenhouse gases.
But last summer, on the southern coast of Alaska, researchers found out hope shine: The evolution of dark sunloungers, during the apparition, Prince William Sound disappeared.
"We do not know exactly when it came from," said Brenda Konar, an Alaskan Marine Biologist professor at Fairbanks, who was not involved in the study of Science Progress. "They were very small and they do not know how to survive, so we'll be curious about what we'll see next summer."
If they make a comeback, Arkansas students, now teenagers, will probably be happy.
