Theses and Dissertations
Root hemiparasites are green plants that tap into a neighboring plant’s water-filled xylem to acquire inorganic nutrients, which can lead to an accumulation of nutrients in hemiparasite biomass. I performed an observational field study at Nachusa Grasslands and Franklin Creek State Natural Area (Lee County, IL) in 2019 to investigate how the presence of five root hemiparasites (Aureolaria grandiflora (Benth.) Pennell, Agalinis tenuifolia (Vahl) Raf., Castilleja sessiliflora (Pursh), Dasistoma macrophylla (Nutt.) Raf., Pedicularis canadensis L.) affects their communities through the (a)keystone species hypothesis, that hemiparasites will increase measures of diversity by altering competition among surrounding plant species, (b) ecological engineer …
