Overview of all devices with separate inlets (type 1). (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.
