Bacteria of sorts
This is a small stream fed by a spring about 100 ft. away. The There are two predominant life forms here: Cylindrospermum (green stuff); Sphaerotilus (brown stuff). These are blue green algae or cyanobacteria and a filamentous sheathed bacteria, respectively. I posted a photomicrograph of the Cylindrospermum: www.flickr.com/photos/14643312@N02/16819180235/ and earlier a photomicrograph of the Sphaerotilus: www.flickr.com/photos/14643312@N02/13861877713/in/set-721....
Losensky Park has several springs, likely fed by the impoudment of the Pucker Street Dam. My spirogyra studies have focused on the spring nearest the dam. It shows no macro signs of iron content. Those springs at the lower elevation nearer the Dowagiac River show significant iron content, i.e., stained rock/soil. These spring sources are dominated by Sphaerotilus, a filamentous sheathed bacteria.
