Older trees grow at a rate greater
Trees increase the pace of growth as they grow older, according to a new study published yesterday in the journal Nature."The trees continue to grow so intense during its life cycle," said Nate Stephenson, study leader and forest ecologist of the US Geological Survey, in Three Rivers, California.The research studied 403 species of trees from around the world and concluded that these never suffer from problems of old age. In animals, the change and ageing of cells will ultimately determine his death. But the trees do not have identical problems, only diseases, insects, the man, fire or accidents â€" like lightning â€" the can kill."They never stop growing. Each year that passes, always weigh more than in the previous year ", explained Stephenson.Until now, it was believed that the trees stop growing older as they were made. A 2010 study was the first to go against this theory, when concluded that the giant California trees continue to grow into the sky each year that passed â€" and at a pace always greater.Was this example it took Stephenson trying to learn more about the growth of trees â€" and if this was connected to his old age.The study evaluated more than 670 thousand tropical and temperate climates trees â€" about 90% of these grow increasingly larger rhythms. The oldest trees can grow to 600 pounds per year.Foto:  tkerpe / Creative Commons
