More CO2, More Poison Ivy

Given that poison ivy (Toxicodendron radicans) is a risk to public health it’s not surprising that a group of researchers have been busy the last few years trying to figure out how climate change is going to affect it. And as shown in the graphic above, poison ivy has a particularly strong and positive response to increased CO2 in the atmosphere.

The graphic is an illustration of research by University of Georgia assistant professor Jacqueline Mohan, which was published in the Proceedings of the National Academy of Sciences in 2006. She worked in an experimental research facility at the Duke University Forest in North Carolina. This experiment is one of a number of free-air CO2 enrichment (FACE) experiments in the United States, which have been set up to help researchers study the response of ecosystems to increased CO2 environments.
