| Description
| - Masožravá rostlina Utricularia australis byla sbírána na 30 místech v ČR a její minerální výživa byla korelována s její masožravostí. Byly hledány vztahy mezi hladinou minerálních živin ve vodě a množstvím chycené kořisti v pastech, obsahem N, P, K, Na, Ca a Mg v prýtech a podílem celkové biomasy rostliny v pastech (investice do masožravosti). I na velmi oligotrofních místech s nízkým chytáním kořisti byl prýtový obsah N a P vždy hodně nad limitující hladinou pro růst. Rostliny reutilizovaly alespoň 57 % N a 81 % P ze senescentních prýtů, ale ztratily z nich veškerý K, Na, Ca a Mg. Investice do masožravosti (23-61 %) korelovala pozitivně s koncentrací CO2, ale záporně s prýtovým obsahem N. Prýtový obsah N je tedy klíčovým endogenním faktorem regulujícím investici do masožravosti přes zpětnovazebný mechanismus. (cs)
- The carnivorous plant Utricularia australis was sampled from 30 locations in the Czech Republic and its mineral nutrient economy was correlated with its carnivorous habit. Relationships were sought between mineral nutrient levels in the ambient water together with prey quantity captured in traps and N, P, K, Na, Ca, and Mg contents of shoot tissues, and the proportion of total plant biomass in traps (investment in carnivory). Even at very oligotrophic sites with low prey capture rates, shoot N and P content was always well above the level below which growth limitation could occur. Plants recycled at least 57 % of their N and 81 % of their P from senescent shoots, although they lost all of the K, Na, Ca, and Mg from senescing tissues. The investment in carnivory (23-61 %) positively correlated with CO2 concentration, but negatively with shoot N content. Thus, shoot N content acts as a key endogenous factor regulating investment in trap biomass through a negative feedback mechanism.
