Leaf absorption of mineral nutrients in carnivorous plants stimulates root nutrient uptake
• The mineral nutrition of terrestrial carnivorous plants was investigated under glasshouse conditions to elucidate ecophysiological adaptations of this plant group. • In Drosera capillaris and D. capensis, absorption of N, P, K, and Mg from insects was relatively efficient (> 43%), whereas that of Ca was not. Carnivorous plants (D. capensis, D. peltata, D. scorpioides, and Dionaea muscipula) e...
متن کاملCarnivorous plants
Figure 1. Carnivorous plants. When we chew and then swallow meat, we stimulate glands (pancreatic acinar cells) to secrete hydrochloric acid and proteases. Amino acids released into the human stomach by the acidic lytic sap are forwarded to and taken up by the intestine. When compared with the human endocrine system, the Venus flytrap also operates as a mouth, stomach and intestine, all combine...
متن کاملEvolutionary ecology of carnivorous plants
Nicholas J. Gotelli Dept of Biology, University of Vermont, Burlington, VT 05405, USA. Carnivorous plants have fascinated evolutionary ecologists, botanists and horticulturists for centuries. Early investigators were reluctant to accept that plants could consume insects and other small invertebrates1; Darwin2 provided the first detailed experimental evidence for carnivory in several genera. Sin...
متن کاملFoliar mineral nutrient uptake in carnivorous plants: what do we know and what should we know?
CARNIVOROUS PLANTS AS ECOLOGICAL GROUP Carnivorous plants (CPs) usually grow in nutrient-poor, wet or aquatic environments and possess foliar traps which capture animal prey (Juniper et al., 1989). There are about 600 terrestrial and 50 aquatic or amphibious species of CPs which supplement the conventional mineral nutrient uptake by roots or shoots from their environment by the absorption of nu...
متن کاملNutrient limitation and stoichiometry of carnivorous plants.
The cost-benefit model for the evolution of carnivorous plants posits a trade-off between photosynthetic costs associated with carnivorous structures and photosynthetic benefits accrued through additional nutrient acquisition. The model predicts that carnivory is expected to evolve if its marginal benefits exceed its marginal costs. Further, the model predicts that when nutrients are scarce but...
