 "Lepidium draba" did not seem to follow any of the postulates of the EICA Hypothesis, as the researchers of the study understood them.Through most of the studies done on the EICA Hypothesis (see examples above), it holds that the introduced populations of invasive plant species are less able to cope with the pressures of specialist herbivores than native populations of the same species are, suggesting that invasive species "do" respond to accelerated natural selection after being released from the selective pressure of specialist herbivores and "do" have the potential to reallocate resources away from specific forms of defense.However, not all of these introduced populations produce significantly more biomass than the native populations of the same species under laboratory conditions.
