Current Projects

As part of a cottonwood common garden experiment, 1000 Populus trichocarpa from the center of its natural range are being propagated in the Northern Arizona University Research Greenhouses (managed by Phil Patterson), in preparation for spring planting at a SEGA field site in Arizona and... read more

This National Science Foundation supported research effort will examine how future climate change and invasive species will affect Fremont cottonwood trees and the plants and animals that depend upon them. Fremont cottonwood is a disproportionately important species, or “foundation species,” of... read more

Because of climate change, plants will either have to tolerate new climate conditions, or migrate. Our research group hopes to determine the role that soil organisms play in helping plants adapt to emerging new environments, and helping plants survive when humans assist their migration. Our... read more

This research effort will examine the combined impacts of climate change and invasive species pressure on native bunchgrases using the elevational gradient of the San Francisco Peaks. By establishing multiple common gardens, one at The Arboretum at Flagstaff and then other at the Chevelon... read more

The role of genetics in herbivore resistance, growth and stress tolerance of Nicotiana attenua. A study to examine the role of genetics in herbivore resistance, growth and stress tolerance of Nicotiana attenua (commonly known as wild or coyote tobacco) is taking place at the SEGA Walnut Creek (... read more
This project will assess genetic variation in fitness and ecophysiological traits in Bouteloua gracilis, an important rangeland restoration species. We will plant out multiple maternal families (half- or full-sib) from 36 populations collected from across the Colorado Plateau along with... read more
Southwestern white pine is an important tree species of southwestern mixed conifer forests that is also host to a non-native fungal pathogen (white pine blister rust). Our research will examine adaptive traits (e.g. cold hardiness, drought tolerance, and rust resistance) and the influence of... read more
