Aquatic Osteoporosis

This phenomenon called "aquatic osteoporosis" has been discovered by researchers from Queen's and York universities. This is actually much more serious than it seems, apparently there has been a dramatic decline of Calcium Levels in several lakes of North America and with these declining levels comes the demise of aquatic species. They were able to determine the damage by its effect on the invertebrate Daphnia or common name the "water flea." Daphnia is an organism that starts at the very bottom of the food web and without them the higher taxa will also have an effect and eventually leading to endagered species so the discovery of this is important. How much damage has been done is still not accurate been they do know it has already taken a huge toll in some bodies of water. They have linked the problem to the long-term effects of acid rain on forest soils, as well as to logging and forest re-growth. Researchers also noted that, despite signs of chemical recovery from recent reductions in sulphur dioxide emissions, lower calcium levels may delay the biological recovery of lakes from acidification. Let's just hope this finding didn't come too late.
