After a decade of death, Canadian scientists say they have found C Star Killer
Scientists say that they have found the reason behind the disease that converts the live, 24-head sea stars into a puddle.
A research scientist at Hakai Institute is part of a team that has spent years to investigate the cause of the disease. His research was published in the magazine on Monday Nature Ecology and Development,
“Agent is a bacterial. It is called Pectinicida“Prantis told CBC News.
These organisms were pushed to the verge of extinction after a decade, experts say that this is not only for this species, but also for a significant support in the defense of humanity against climate change, the first step for recovery.
Twisted weapons
The most affected species are sunflower marine stars, once proud of a border along the west coast of North America, from Baja California to Alaska.
Then, in 2013, the C Star died on a large scale from a ruined disease.
And this is a fierce end.
“Their arms bend back to themselves, so they meet in a way in puzzle pieces,” said Equalist Eclagist Alyssa wheatman.
They then lose their arms, and then, “Their arms will move away from their body.”
Shortly thereafter, the wheat says that more sea stars dissolve and die.
Paper estimates that more than 87 percent of sunflower sea stars have been killed in the northern parts of the west coast. In the southern housing range, species are considered functional extinct.
“When this was the first time, it was just fields and dyeing -c -star Go’s Pokhar farm,” said Sara Hamilton, the coordinator of the science of Oregon Kelp Alliance. Hamilton was not involved in research.
“It was something out of a horror film.”
Hunting for star killer
Many principles identifying the cause were either not excluded or rejected.
What the team did in this case took healthy sea stars to the laboratory and exposed them to infection. He did so over the years and separated the cause to separate the cause.
Wheatman explained this process: “We take the body’s fluid or tissue from a sick star and then we use the experimental other sea stars in experimental way we know that they are healthy.”
The result of paper was that 92 percent of these exposure served a healthy star to transmit the disease – killing it within 20 days.
These experiments also revealed that Pectinicida Most likely was criminal.
Experts are influenced by the hard work and effort of paper.
Hamilton of Oregon Kelp Alliance said, “When they get a level of evidence they just don’t stop – they went and found a second level of evidence and a third level of evidence,” Hamilton said, Hamilon said, Hamilton of Oregon Kelp Alliance said.
Ocean Protection Professor Amanda Bates at the University of Victoria also said, “There is a route – essentially that you separate the disease agents and add them to cause an outbreak – and this research team fully followed those processes.”
Hope for recovery
Gives hope for restoration efforts to find out the reason, experts say.
“Now we can go out and actually test and see the real prevalence of this pathogen in the area,” the wheat said.
In addition, any captive breeding programs that are trying to restore the sea star population can now test and test those population before bringing them back into a risky environment.
Hamilton agrees.
“This is one of the things we are most concerned about some of these recovery efforts,” he said.
“If we deed and outplant captives, we certainly do not want to present … a new outbreak of the disease.”
Lost decade
Bates, who has seen the disease by 2009, is cautious about the congestion of recovery.
“When we know that the disease affects us as humans, I think we often forget that it affects wildlife,” he told CBC News.
“We are really a decade since the large large -scale mortality incident, and we still do not have Paiconopodia (Sunflower sea stars) Recover in many places. ,
Hamilton stated that the reproduction of sunflower marine stars would be valuable because their absence means what is meant for the ecosystem. The population of marine urin has increased – which also means that the Kelp forests have been removed.
“Archin is like the goats of the sea,” he said. “They will eat anything, they will simply lower things.”
Restoring sea stars means that Kelp forests can thrive once again. This would mean that biodiversity, food, improvement in tourism, as well as supercised erosion by climate change and action against storms will have to be served as a beach defense.
“This is definitely our partner in the climate crisis,” said Prantis.
“I think when we are talking about marine stars ruined disease, we are not just talking about marine star species – which we love ourselves – but the whole marine ecosystem that has collapsed due to this epidemic.”
