This study demonstrates that different total P. fraction releases may differ between two bodies of water under similar oxygen conditions (Kisand & Noges, 2003). This study is important in that it highlights the complexity of understanding P. fractions in any given body of water. There are a multitude of potential reactions in any body of water. Oxygen plays a role in the reactions of any individual lake, but one cannot make predictions based on oxygen level alone.

Shallow lakes differ from stratified lakes in many ways. A stratified lake typically reaches equilibria in such a manner that it becomes divided into regions. This is not the case with shallow lakes. With a shallow lake, the entire lake may change from clear water to macrophyte dominated to algae dominated, each phase has its own state of equilibrium (Dokulil & Teubner, 2003). Total chlorophyll to phosphorus ratios are different in these various...
