Principal Response Curve (PRC): ordination method representing the main community response (y-axis, effect) to the treatment effect over time (x-axis, days) with respect to the controls (continuous line in the middle of the graph represent the C and the lines in black, red, green and blue represent L, H, CU and I treatments). The axis on the right summarizes the zooplankton community response based on its more influent taxa; it represents the species weights expressed as the level of affinity that each taxa had with the main trend of the PRC (n = 5).
