Hot seas and starfish that are disappearing



According to a recent study, the combination of infectious diseases and hot water cross the solar starfish population on the Pacific coast. A solar starfish has been seen at Neah Bay, Wash., In the photo caption in 2013.

VANCOUVER – Water and contaminating diseases have been identified as a cause of a destructive eastern star, a recent study published in the Pacific Coast.

The stars of the Sunflower Sea are the world's largest stars in the world and are brightly colored, including purple and orange. Some of them extend to more than one meter and therefore "literally run across the boat," said Joseph Gaydos, the author of the study.

"But when this disease occurs, it's like zombie apocalypse," said Gaydos, the SeaDoc Society at the University of California, Davis.

"You can have 24 arms and suddenly walk around and your arms are falling. And then, suddenly, the whole body seems to melt."

He used "the great and beautiful star of the sea," and said that, within a few days weighing about five kilograms, it was similar to dirt pilots.

"The sun is a very ugly and rapid disease of these seas".

In 2013, scientists warned the population of species that are diminishing between 80 and 100 percent in deepwater and deep water in Alaska and British Columbia. The population information gathered divers and deep catches.

The star of the Sunflower Sea is water of hundreds meters, three meters.

Diego Montecino-Latorre, a research fellow, and also at the University of California of Davis, scientists found the meeting point between the water temperature and the lesser star of the sea.

Gaydos said that the water temperature was not increasing in all areas.

The oceans "do not like a bathtub" at a consistent temperature, said that in some parts of California, there was an increase of around 4 C, while Washington witnessed a 2.5 C increase.

The scientist's proposed theory is that adding the temperature to the star of the sea that has undergone a temperature illness, the starfish not only say about the complex immune systems,

Drew Harvell, professor of evolutionary ecology and evolutionary biology at Cornell University, said ocean warming causes global warming to increase wave sickness and kill starfish faster.

Gaydos said that the sea-starlings of sunflowers are wild predators and that the amount of salt water can increase.

Such illness could have a great impact on the entire ecosystem, he said.

"Urchins can lower the kelp forests and then lose the algae biodiversity," he said. "Kelp is a place to hide fish, kel is another animal food".

Kelp beds were struggling, he added.

"Kelp does not do well when the ocean temperature increases, so it's just like a kelp mold."

A Kelp aid option is a sewerage pickup team that is testing in California, Gaydos said.

And it is an opportunity to help the star team of Sunflower People to choose a virus that is more resistant to animals.

Gaydos said an awake-up call.

"It's hard to see what's happening in the ocean, but it's been a very short time," he said. "To disappear an entire species, it is not good".
