NAU awarded $2.5 million to examine genetic response of ‘foundation’ species to climate impacts
The
National Science Foundation has awarded Northern Arizona University a
five-year, $2.5 million grant to examine how future climate change and
invasive species will
affect Fremont cottonwood trees, a “foundation species” of the
Southwest’s rapidly vanishing stream-side habitats.
The
research team will use the Southwest Experimental Garden Array, a new
genetics-based research platform that allows scientists to quantify the
ecological and evolutionary
responses of species to changing climate conditions. With the resulting
data, genetics-based models will be used to explain how the genetic
connectivity of foundation species, climate change and exotic species
interact to affect hundreds of dependent species.
