Jelly-covered plankton multiplying in Canadian lakes – Technology & Science – CBC News

Jelly-covered plankton that look like tapioca are multiplying in many Canadian lakes, clogging up water pipes and potentially disrupting the food chain.The population of freshwater plankton called Holopedium has doubled in Ontario lakes between the mid-1980s and the mid-2000s, reports a study published this week in Proceedings of the Royal Society B. The plankton are thriving in lakes that are low in calcium — and the calcium levels of many lakes have fallen in recent decades because of acid rain and logging.
