Synergy isn’t always a good thing — take climate change and invasive plants.

Scientists have long hypothesized that climate change, by intensifying stressors like drought or wildfires, would make an ecosystem more vulnerable to invasive plants. Those invasive plants may in turn alter the environment in ways that amplify the impacts of climate change, explained Luke Flory, a professor of ecology in the UF/IFAS agronomy department.

A new long-term field study conducted by Flory’s lab offers the first experimental evidence to support this hypothesis.

The study, published in the journal “Ecology Letters,” exposed small plots of long-leaf pine to three scenarios: drought conditions, colonization by the invasive plant cogongrass and a combination of these two factors.
