Figure 7. LLO scientists are using unique DNA fingerprints to discover new forms of biodiversity in large lakes. In this image, ESOM (Emergent Self Organizing Maps) shows the genetic relatedness of distinct microorganisms found in Lake Superior sediment using color and spatial position. Each point represents a DNA fragment which has been colored according to its taxonomy. Applying advanced genomic tools such as this can yield unique insight to cycling of elements like carbon and nitrogen in natural environments. Computer image by Cody Sheik.
