Plants show adaptability to climate change

Increased carbon dioxide levels can affect some plants’ defense mechanisms against preying insects, a recent study from the University of Michigan has found.


In an evaluation of chemical and physical changes of milkweed plants in response to elevated levels of carbon dioxide, some plant families increased their production of toxic compounds used to deter hungry insects. In plants whose toxin levels were reduced, stronger physical defenses like tougher leaves and the ability to grow back faster were exhibited.

The study suggests that in the face of rising carbon levels in the atmosphere, certain plant species are quite adaptable to change.
