Definition of six different microenvironments based on trajectory patterns. (3a) Example of the grid applied to replicate 1. The grid cells corresponding to each microenvironment are outlined in different colors. The colors are labelled in 3c-h. (3b) The grids applied to the other two movie replicates and the respective colored labels. (3c,d,e,f,g,h) Trajectory patterns for six different microenvironments in replicate 1: from left to right P. parasitica (proximal to KCl injection point vs. distant from KCl injection point) from cells A1-A2-A3 and C1-C2-C3 of the grid; V. microstoma analysis (sessile vs free-swimming forms) from cells A5-A6 and C4-C5-C6; E. aerogenes analysis (in proximity to V. microstoma (V) sessile forms vs. distant from V sessile forms) from cells A5-A6 and C3-C4. The color bar below each image indicates the mean speeds (µm/s).
