Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch
Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch
Electronic Theses and Dissertations
At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to include overstory, …

Community Ecology Of Soil Microbes In Southeast Usa Oak-Pine Woodlands, Ann L. Rasmussen
Electronic Theses and Dissertations
Soil microbial communities can have important effects on plant growth and plant community ecology; however, the relationships between trees and soil microbial communities are still relatively poorly understood. Here i examine several of these relationships. Chapter 1 examines how ecological restoration and environmental conditions affect the community composition and enzyme activities of Ectomycorrhizal fungi (emf). Chapter 2 considers whether host specificity in emf structures taxa occurrence on oaks and pines, and chapter 3 investigates how ash addition affects oak seedling growth and the soil bacterial community. I found that while wildfire lowered emf diversity, prescribed burning did not. Ectomycorrhizal root …
