Tiers of Complexity (image) Carnegie Institution for Science Share Print E-Mail Caption Capturing tiers of complexity: from genomes to cells to hot spring microbial mat communities of Yellowstone National Park are shown. From left to right: Circos graph depicting extensive genomic rearrangements between two sequenced cyanobacterial genomes called Synechococcus OSA and OS-B' (in red and blue respectively); a population of Synechococcus cells cultured in the lab exhibiting natural fluorescence; and a microbial mat community in Octopus Spring in Yellowstone National Park.
