Using a site in Northern California, you repeat Stiling and Drake’s experiments in elevated and ambient CO2 chambers, and achieve similar results. However, you notice that for one species of herbivore, the mortality rate from predators and parasitoids is equal in the elevated and ambient chambers, while the mortality rate due to nutritional inadequacy is higher in elevated chambers. The herbivore species in question is native to Asia and has only recently arrived in the United States. What is a likely explanation for your findings?
