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.

The third image is common mildew – not collected from College Creek – specimen provided by Celestron – but fascinating nontheless!
