Overview of all devices with a single inlet (type 2). (A) Each kymograph shows the average occupancy per patch in a single habitat. Kymographs for the five parallel habitats in a single device are shown next to each other. Note that all habitats on the same device are inoculated from the same culture set. (B) The device-wide averages of the occupancies of strains JEK1037 (R, red) and JEK1036 (G, green) and the red fraction (fr black) are shown as function of time. Dashed lines indicate mean ± sem. The red fraction (fr) is calculated for each habitat as fr = r/(r + g), where r and g are the habitat-wide average occupancies of strains JEK1037 (red) and JEK1036 (green) respectively. Habitats where one (or both) of the strains failed to enter (e.g. when there is a constriction in one of the inlet channels) were excluded from the analysis and are shown as grey panels in this figure. Note that devices 10 and 11 were inoculated from the same initial cultures.
