ScienceDaily (July 4, 2012) — University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size.

The study, which is the first of its kind in the world, highlights that plant species are already responding to changes in climate. The results are published online July 4 in the Royal Society journal Biology Letters.

"Climate change is often discussed in terms of future impacts, but changes in temperature over recent decades have already been ecologically significant," says Dr Greg Guerin, a Postdoctoral Fellow with the University of Adelaide's School of Earth and Environmental Sciences and lead author of the study.
