(a) Fraction of time spent in the inner half of the tank (within 39.2 cm of its center, which represents half of its area) as a function of group size in cave populations. (b) Percentage increase of the fraction in the center as a function of the percentage increase of the mean swimming speed in cave populations. Each colored cross represents the average of a specific population and group size. Increase percentages are computed using the isolated-fish mean as reference. This is done independently for each population. As a result, all three isolated-fish crosses (one for each population) are located at (0%, 0%). The black dashed curve shows the results of the computational model.
