What’s in your water?

Fun fact of the day:   One milliliter (mL) of lake water contains more than one billion individual cells!  (Brock Biology of Microorganisms)

Our aquatic ecosystems house an amazing amount of biological diversity.  Nate’s post a few weeks back addressed the occurrence of bryozoa colonies in aquatic ecosystems in the Upper Midwest and Canada.  Today we’re moving even smaller – bacteria, archaea, and algae, to name a few.  While many of these tiny living organisms are too small to see with the naked eye, we can get some insight with the help of a microscope.

These photographs were captured with a Celestron LCD digital microscope.  The first two images are from water samples collected from College Creek in Ames in mid-September.   The third image is common mildew – not collected from College Creek – specimen provided by Celestron –  but fascinating nontheless!
