The stars disappear

A recent study suggests that the combination of hot water and infectious diseases has been identified as a cause of the extinction of Sunflower star population along the Pacific coast.
Co-author Drew Harvell, a professor of ecology and evolutionary biology at Cornell University, says the ocean wave heat wave caused by global warming makes the sea star a loss of the disease and faster killing of the starfish.
Scientists have noted that in three years, starting in 2013, populations of this species decreased between 80 and 100 percent in deep and shallow waters from Alaska and British Columbia to California.
The study says that the starfish starfish is the size of the shark lid with a huge appetite that slides above the sea floor like a robotic vacuum cleaner, eating everything in its path.
Joseph Gaydos, with the SeaDoc company from the California University, Davis, says sunfish starfish are important because they keep seaweeds under control.
Gaydos, a senior author of the study, says that without the stars of sunflowers, rabbit populations widen and threaten the forests of cola and biodiversity.
