Effects of plain polystyrene beads on the mobility of three clonal morpho-physiological types of Daphnia longispina species complex. Panels A, C, and F refer to dose–response curves after exposure from 24 to 96 h to 50 nm beads whereas panels B, D, and E display data for exposure to 100 nm beads during the same period. Within each panel, light blue unfilled circles represent measured points at 24 h, whereas light blue dotted-dashed lines represent 24 h regression. Likewise, the dark blue filled circles (with dotted lines), black triangle (with dashed lines), and black squares (with continuous lines) represent measured values and regression lines for respectively 48 h, 72 h, and 96 h
