Proportionality of key locomotion parameters in a variety of environments
Figure 1. (a)-(c) Proportionality of frequency, wavelength, and amplitude in a variety of environments: gelatin, deformable agar surface and non-deformable membrane surface. Lines show the best linear fits to the data. (d)-(f) Frequency, wavelength, and amplitude of the locomotion wave all decay smoothly with K in the different media gelatin and agar. Lines show the best power-law fits to the data. Note the doubly logarithmic scales. In all graphs, filled circles show gelatin data, and different colors represent different gelatin concentrations. Agar and membrane data are represented by black triangles and white squares respectively. For each data point n ≥ 3 replicates were used. K is an estimation of the ratio between lateral and longitudinal drag the worm encounters while moving in different environments.
