Did 'Ja Know
In early December 2016 after a record-warm autumn in the United States, University of Minnesota Duluth researchers and their colleagues published the first evidence that well-documented climatic changes have produced a biological change within the Laurentian Great Lakes. Specifically, there are many more tiny phytoplankton from the group Cyclotella floating around and fewer large-celled algae. The scientists think the abundance of Cyclotella reflects new physical regimes such as a deeper summer surface layers that persist for longer times.
