This is Scientific American - 60 Second Science. I am ...This will just take a minute. When it comes to mussels, bigger is not necessarily better. Tiny fibers called bissels and able muscles ,the shell fish kind,to anger themselves to coast lines,despite crushing ocean waves. But new research shows the attachment fibers weakened in warm waters. As temperature rise 15 Degrees Fahrenheit, lessons fiber shrink by 60%, possibly causing them to fail completely. As climate change raises ocean temperatures, mussels may be enforced to cooler water. Emily Cliton of the University of Washington presented the research at the meeting of the American Assosiation for the Advancement of Science in Boston.
Researcher have dicacted mussels that been found, I think, up righ to 100 different species. So mussels group has really changed our community. We also eat mussels and so there are application in the agriculture. The way they grow the mussels is the mussels have to remain attach on the long lines, so if the mussels fall off before the farmer return to raise the harvest, then they will lost lots of money. |
