Landscape Genetic Connectivity of a Foundation Tree Species: Implications for Dependent Communities Facing Climate Change and Exotic Species Invasion

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 the Southwest’s rapidly vanishing stream-side habitats. A major portion of this work will involve sequencing the genome of Fremont cottonwood to identify single nucleotide polymorphisms (SNPs). These markers will be used to assess landscape-level connectivity and its relationship to climate change, exotic species invasion, and community connectivity of dependent arthropod communities.
