Carnivorous 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 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...
متن کاملOvercoming DNA extraction problems from carnivorous plants
Fleischmann, A. & Heubl, G. 2009. Overcoming DNA extraction problems from carnivorous plants. Anales Jard. Bot. Madrid 66(2): 209-215. We tested previously published protocols for DNA isolation from plants with high contents of polyphenols and polysaccharides for several taxa of carnivorous plants. However, we did not get satisfying results with fresh or silica dried leaf tissue obtained from f...
متن کاملEvidence for competition between carnivorous plants and spiders.
Several studies have demonstrated that competition between disparate taxa can be important in determining community structure, yet surprisingly, to our knowledge, no quantitative studies have been conducted on competition between carnivorous plants and animals. To examine potential competition between these taxa, we studied dietary and microhabitat overlap between pink sundews (Drosera capillar...
