Description
  • Utricularia ochroleuca (vč. U. stygia) a U. intermedia jsou vodní masožravé rostliny s výrazně dvojtvarými prýty. Investice do masožravosti jako podíl pastí a masožravých prýtů v celkové biomase rostlin a morfometrické charakteristiky obou typů prýtů byly zjišťovány v hustých porostech těchto druhů v mělkých dystrofních vodách na nejbohatších lokalitách v Třeboňské pánvi v ČR a byly zvažovány jejich možné ekologické regulace a mezidruhové rozdíly. V těchto porostech byly měřeny ve vertikálním profilu chemické a fyzikální faktory, aby se rozlišily klíčové mikrostanovištní faktory pro zelené fotosyntetické prýty a nezelené masožravé prýty s pastmi. Celková sušina obou druhů v hustých porostech dosahovala 2,4–97,0 g.m–2. Podíl masožravých prýtů jako investice do masožravosti z celkové biomasy byl v rozsahu 40–59% a podíl pastí 18–29% u obou druhů. Průměrná délka hlavních masožravých prýtů a počet pastí na rostlinu u masožravých prýtů obou druhů se vysoce statisticky průkazně odlišovaly mezi lokalitami... (cs)
  • Utricularia stygia (incl. U. ochroleuca) and U. intermedia are aquatic carnivorous plants with distinctly dimorphic shoots. Investment in carnivory and the morphometric characteristics of both types of shoots of these plants were determined in dense stands growing in shallow dystrophic waters in the Třeboň basin, Czech Republic, and their possible ecological regulation and interspecific differences considered. Vertical profiles of chemical and physical microhabitat factors were measured in these stands in order to differentiate key microhabitat factors associated with photosynthetic and carnivorous shoots. Total dry biomass of both species in dense stands ranged between 2.4–97.0 g.m–2. The percentage of carnivorous shoots in the total biomass, which was used a a measure of the investment in carnivory, ranged from 40–59% and that of traps from 18–29% in both species. The high percentage of total biomass made up of carnivorous shoots in both species indicates both a high structural investment in carn...
