Muskoka's lakes face new environmental threat: report http://apocadocs.com/s.pl?1229359965
According to the study, long-term consequences of calcium decline could result in areas where forests won't grow back well. Lakes could also start to lose calcium-rich organisms.
A type of water flea, Daphnia, was the aquatic creature studied in the report, said Yan. The water flea is a crustacean, like little tiny shrimp, not an insect, he said.... "We are kind of likening these water fleas to canaries in the coal mine," Yan explained. "So if one calcium-rich animal is in trouble, then we darn well better find out about all the other calcium-rich animals, like crayfish and snails."... In the industrial age, minerals in the soil were leached through acid rain and logging.
"What takes the minerals away is six decades of acid rain and then logging, followed by forest regrowth," said Yan.
