Print… the status of living systems provides the most direct and most effective measure of the "integrity of water," the resource on which all life depends."
James R. Karr and Ellen W. Chu, 1997
Biological Monitoring…
Aquatic ecosystems are some of the most amazing habitats on Earth. Their species and communities are staggeringly diverse. Lesson 6 is but a brief introduction into the complexities of biological communities that are dependent upon freshwater. Trained as a biologist, I have observed, investigated, and experienced aquatic ecosystems all of my life, and still I know there is so much more to learn. For this lesson, my advice is to sample the fascinating species and vital services provided by these systems, and maybe it will provide a springboard of interest into their natural history and their never-ending diversity. I hope you enjoy this part of the journey.
