Figure 2From: Temporal changes in species interactions in simple aquatic bacterial communitiesSpecies abundances in two-species communities. Fluctuations in the relative abundance of S. marcescens to N. capsulatum in two-species communities (based on CFUml-1). Reference lines indicate when species abundances are equal (black line at Y-axis = 1), or when S. marcescens is ten times more abundant than N. capsulatum (grey line at Y-axis = 10).Back to article page
