Paul Barnes joined the Department of Biological Sciences in 2004. Dr. Barnes' research examines the functional ecology of plants and global change biology. Specific research topics include physiological plant ecology; grassland & savanna ecology; plant & ecosystem responses to global environmental change; environmental UV photobiology; mechanisms of plant-plant interactions; and plant carbon, water and light relations.
