Eutrophication: A Silent Killer of Lakes
Eutrophication is the nutrient enrichment of waters that stimulates an array of symptomatic changes that can include increased phytoplankton and rooted aquatic plant (macrophyte) production, fisheries and water quality deterioration, and other undesirable changes that interfere with water uses. For a layman eutrophication is simply a nutrient enrichment or fertility of lake. The impacts of eutrophication are more severe than recognized. Vonlanthen and his co-workers (Nature, 2012) provided an evidence that eutrophication can lead to extinction or ‘speciation reversal’ and ‘demographic reversal’ in Whitefish across European Lakes.

Eutrophication is most often the result of an elevated supply of nutrients, particularly nitrogen and phosphorus, to surface waters that results in enhanced production of primary producers, particularly phytoplankton and aquatic plants.

Gender-bending Chemicals in Water Supply - Researchers from the University of Calgary sampled populations of longnose dace, a silvery minnow, in Alberta’s Oldman and Bow Rivers. The Bow River flows through downtown Calgary and supplies its drinking water. Samples were taken back to the lab and dissected for further analysis and biologists then noticed that the random catch was overwhelmingly female.
