Scientists with the Merriam-Powell Center for Environmental Research have received a four-year, $859,000 grant from the National Science Foundation to assess how cottonwood trees … Read more about NAU research team receives grant to study how trees adapt to insect damage and the changing environment
When a tree species supports more than 1,000 animals, birds, insects and microbes, the tree type can be considered too big to fail. “Cottonwoods are the General Motors of the plant world because they define a community and an ecosystem,” said Tom Whitham, Regents’ professor of biological sciences. Whitham’s genetics-based research is designed to conserve cottonwoods in the face of climate change.
In the southwestern United States, Fremont cottonwoods grow at sea level up to elevations of 6,600 feet. These… Read more
A new partnership between Cline Library and the Southwest Experimental Garden Array will use repeat photography to document earlier ecological and environmental conditions at garden sites distributed throughout northern Arizona to research how species respond to climate change and land-use management.
“By comparing historical and contemporary photos, researchers can literally see how the plant community is changing over time, which is tremendously valuable,” said Thomas Whitham, SEGA’s principal investigator and NAU Regents’ Professor. “For example, repeat photography allows us to… Read more
