VANCOUVER – A newly published study states that the combination of hot water and infectious diseases has been identified as the cause of the death of sunflower populations along the Pacific Ocean coast.
Drew Harvell, a professor of ecology and evolutionary biology at Cornell University, says a wave of hot waves in the oceans caused by global warming is aggravating marine star disease and killing starfighters faster.
Scientists have noticed that in three years from 2013, populations of this species have dropped 80 to 100 percent in deep and shallow waters from Alaska and British Columbia directly to California.
The study says the sunflower sea star is the size of a hatch with a huge taste that crawls on the sea floor like a robotic vacuum cleaner, eating everything in its way.
Joseph Gaydos, with SeaDoc, of the University of California, Davis, says sunflower sea stars are important because they keep the sea urchins under control.
Gaydos, the lead author of the study, says that without sunflower stars the population of marshes is spreading and threatening algae and biodiversity.
