Does feeding enhance photosynthetic efficiency in the carnivorous pitcher plant Nepenthes talangensis?
Feeding pitchers with insect larvae increases A(N) of leaf laminae, due to higher nutrient acquisition, with strong correlation with nitrogen concentration, but A(N) of pitchers does not increase, despite increased nitrogen concentration in their tissue. Increased A(N) improves growth and reproduction and is likely to increase the competitive advantage of carnivorous over non-carnivorous plants in nutrient-poor habitats.
Our data were at the lower range when compared with the available literature. Uncertainties in prognostication and the possibility of response to treatment can justify chemotherapy prescriptions in selected cases. We suggest that the focus should move to the provision of adequate and timely supportive care.
