Description	Various ecophysiological investigations are presented in Aldrovanda vesiculosa, a rootless aquatic carnivorous plant. A distinct polarity of N, P, and Ca tissue content per dry mass (DM) unit was found along Aldrovanda shoots. Due to effective re-utilization, relatively small proportions of N (10-13 ) and P (33-43 ) are probably lost with senescent leaf whorls, while there is complete loss of all Ca, K, and Mg. The total content of starch and three free sugars was 26-47 DM along adult shoots, with the maximum in the 7th-10th whorls. About 30 of the total maximum sugar content was probably lost with dead whorls. The plant was found to take up 5-7 times more NH4+ to NO3- from a mineral medium. Under nearly-natural conditions in an outdoor cultivation container, catching of prey led to significantly more rapid growth than in unfed plants. DM of the fed controls was 48 higher than in the unfed plants. The controls produced 0.69 branches per plant, while the unfed plants did not produce any.
