Jennifer L. Ison, PhD


I’m a plant ecologist who is broadly interested in population and community-level dynamics in native plant populations. My research has examined how flowering phenology, plant density, and pollinator taxa affect population genetic structure, inbreeding depression, and population persistence across a fragmented landscape.
