Nutritional benefit from leaf litter utilization in the pitcher plant Nepenthes ampullaria

Popis výsledku v původním jazyce

The pitcher plant Nepenthes ampullaria has an unusual growth pattern, which differs markedly from other species in the carnivorous genus Nepenthes. Its pitchers have a reflexed lid and sit above the soil surface in a tighly packed 'carpet'. They containa significant amount of plant-derived materials, suggesting that this species is partially herbivorous. We tested the hypothesis that the plant benefits from leaf litter utilization by increased photosynthetic efficiency sensu stricto cost/benefit model.Stable nitrogen isotope abundance indicated that N. ampullaria derived around 41.7 +/- 5.5% of lamina and 54.8 +/- 7.0% of pitcher nitrogen from leaf litter. The concentrations of nitrogen and assimilation pigments, and the rate of net photosynthesis (A(N)), increased in the lamina as a result of feeding, but did not increase in the trap. However, maximal (F(v)/F(m)) and effective photochemical quantum yield of photosystem II (Phi(PSII)) were unaffected. Our data indicate that N. ampull
