Figure 5From: Planctomycetes dominate biofilms on surfaces of the kelp Laminaria hyperboreaOverlap of planctomycete OTUs between sampling times. A Venn diagram describing the degree of OTU overlap between the different clone libraries. The total number of OTUs in each library is displayed outside the circles and the number of overlapping OTUs is given inside the areas of the circles. The area-proportional Venn diagram was generated at http://www.venndiagram.tk.Back to article page
