The apical shoot growth rate of fed plants in all three species was significantly higher by 49-85 % than that of the unfed variants and so also was shoot branching. In A. vesiculosa only, tissue N content in apices and shoot segments of fed plants was significantly greater that in unfed plants. Both apical and shoot P content was significantly greater in fed plants of A. vesiculosa and U. australis, while the P contents were the same in U. bremii. Feeding on prey significantly increased RD of shoot apices only in A. vesiculosa. In conclusion, the more rapid growth due to feeding could hypothetically be caused by stimulating the cell division in the youngest parts of shoot apex due to a faster allocation of prey-derived N and P.
