Ecophysiological characteristics of aquatic carnivorous plants: A review

Popis výsledku v původním jazyce

jazyce práce Aquatic carnivorous plants (ACPs) comprise the species Aldrovanda vesiculosa (Droseraceae) and about 50 species of the genus Utricularia (Lentibulariaceae). Eight species of ACPs grow naturally in Danube river countries, most of them are strongly or critically endangered species in single countries, and exhibit a gradual decline. Aquatic carnivorous plants usually grow in shallow standing dystrophic waters, which are predominantly nutrient poor in (inorganic) N and P and commonly also in K, but usually very rich in CO2. Most species of ACPs exhibit very rapid apical shoot growth (1-4 leaf nodes/day), the same rapid basal shoot decay, and high relative growth rate (7-20 d), which is based mainly on shoot branching. Very rapid polar growth of rootless ACPs in nutrient-poor habitats requires ecophysiological adaptations that enable the plants to access the very limited supplies of mineral nutrients. These adaptations include carnivory, efficient mineral nutrient re-utilization (recycling) from senescent shoots, a very high affinity for mineral nutrient uptake from water, and very high net photosynthetic rate. In aquatic Utricularia species, the structural and maintenance costs of traps are considerable, but the plants are able to regulate the proportion of their resources invested in traps (as investment in carnivory) to match variations in habitat factors: particularly water chemistry, prey availability, and level of irradiance. Shoot N or P content is the endogenous feedback factor which regulates investment in carnivory under the conditions of high CO2 availability.
