Influence of Soil Disturbance and Fire on the Distribution of Caesar’s Weed (Urena Lobata) in Pine Flatwoods

Unknown Date (has links)
Novel disturbances can increase the vulnerability of pine flatwoods to exotic species such as Caesar’s weed (Urena lobata), a plant that has invaded many ecosystems. To understand Caesar’s weed response to disturbance, a factorial field manipulation was used to quantify invasion success. Influence of feral swine (Sus scrofa) on the presence of seeds in the area was analyzed. The effect of heat on Caesar’s weed germination was also quantified. A winter fire and mechanical soil disturbance had no statistical effect on the spread of Caesar’s weed. However, in feral swine disturbed soils Caesar’s weed was more likely to be husked and experience less competition from seeds of other species. Low levels of seed heating increased germination. This data can provide information about the influences of fire and soil disturbances on the spread of Caesar’s weed, as well as how fire intensity levels can affect the spread of invasive Caesar’s weed. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
