Fischer-LeRoy Ecology Lab

Our lab has used whole tree water-use studies to address questions related to how forest genetics
might affect ecosystem water-use in cottonwood trees, how riparian plants
respond to soil water, and understanding size-physiology relationships
in ponderosa and limber pine. Student projects in the lab have most
recently included examining patterns in transpiration and photosynthesis
in Salal, and important understory shrub in temperate
rainforests, and patterns of 13C and stomata density in three
oak species of the sky islands (AZ). All our data and images are
available upon request. We welcome collaboration with other labs and
researchers! |
