Other claims from this paper (4)
- Association Cardenolide defence correlations between different plant parts of Asclepias syriaca are minimal.
- Association Correlations in the performance of the specialist insect species are minimal.
- Association None of the three specialist insect species had its performance affected by ingesting cardenolides.
- Mechanism The cost of sequestration is probably caused by physiological limits.
