Dr. Barney works on the causes, consequences, and epidemiology of invasive species to develop innovative mitigation strategies to this element of global change.
Dr. Barney works in a variety of natural and managed ecosystems across the United States, and has projects on both emerging and longstanding invasive species. Current projects include: determining the ecological impact of invasive plant species in natural systems; interaction of propagule pressure, species traits, and receiving habitat characters determining invasion successes; evaluating the role of local adaptation and phenotypic plasticity in range expansion; and the role of epigenetics in stress tolerance.
