A Denroecological Analysis of Disturbance of Remnant Pinus Palustris, Southeastern Virginia
Pinus palustris Miller (longleaf pine), in Virginia, is at the northernmost extent of its range. During presettlement times, this species occurred throughout the Piedmont and Coastal Plain of Virginia in pure and mixed stands, covering 607,000 hectares. This forest type has since been reduced to 81 …

Modeling longleaf pine (Pinus palustris Mill) wood properties using near infrared spectroscopy
… from wood samples taken throughout 10 longleaf (Pinus palustris Mill) trees. Principal components and multiple linear regression were compared for performance in prediction of density, strength, and stiffness. I found both modeling techniques to yield similar prediction accuracies. However, I …

Effects of Fire on the Ectoparasites of Small Mammals in Longleaf Pine (Pinus Palustris) Habitats
I tested the hypothesis that fire significantly decreases prevalence and abundance of ectoparasites and therefore increases the condition of small mammals in longleaf pine habitats. I trapped two areas with paired burned and unburned sites in east central Georgia during 2002 2003. I collected 190 …

Characterization of Sites for Native Herbaceous Understory Restoration in West Gulf Coast Longleaf Pine (Pinus palustris) Savannas
<p>Longleaf pine (<em>Pinus palustris</em>) savannas were once dominant in East Texas and parts of western and central Louisiana. Native understory species have since been removed or reduced by exotic plants that were introduced and from the reduction in the frequency of both wild and prescribed …

The Influence of Overstory Structure on Understory Light Availability in a Longleaf Pine (Pinus palustris Mill.) Forest
Understory light environments are inherently heterogeneous and therefore difficult to characterize. Numerous methods to measure understory light have been assessed in closed-canopied forests; however, the reliability of these methods has not been addressed for open-canopied forests. Therefore, the …

Fine Root Dynamics in a Pinus palustris Mill. Ecosystem: The Role of Sampling Interval and the Soil Environment
… Data were collected for eleven months from a Pinus palustris Miller woodland in southwest Georgia. As sampling interval increased, estimates of production and mortality declined, while estimates of mean fine root lifespan increased. Annual production values ranged from a maximum of 1.26 mm/cm2 …

Soil Morphological, Physical, and Chemical Parameters Affecting Longleaf Pine (Pinus palustris) Site Quality and Ecosystem Restoration Potential in East Texas
… large decline in coverage of longleaf pine (<em>Pinus palustris </em>Mill.) within its range in the southeastern United States since the time of European settlement. Due to this decline, interest has developed in the re-establishment of this species on suitable sites. However, many attempts have …

Population Dynamics in Response to Fire in <i>Quercus laevis - Pinus palustris</i> Barrens and Related Communities in Southeast Virginia
<p>Permanent plots in the Zuni Pine Barrens (Isle of Wight Co., Virginia) were sampled in order to: quantify plant population dynamics in response to fire, compare these dynamics among different moisture regimes, compare the effect of mechanical understory removal to that of fire on tree seedling …

Forgotten Landscapes: Using Original Land Surveys to Understand the Historic Distribution of Cane Brakes in Wayne County, MS
… surveyed landscape, likely second only to<em> Pinus palustris</em> (longleaf pine).</p> <p>This research involved digitizing historical surveyors' notes, transcribing them into a structured format, and extracting spatial data for GIS analysis. The methodology developed for this research can be …

Comparison of the Survival and Growth of West Gulf Coastal Plain Pine in East Texas
… Gulf Coastal Plain provenance loblolly <em>(Pinus taeda</em> L.), longleaf (<em>Pinus palustris</em> Mill.), shortleaf (<em>Pinus echinata</em> Mill.), and slash pines (<em>Pinus elliottii</em> Engelm.) were planted in East Texas to compare initial growth and survival. Containerized seedlings …

Profiling Bat Activity and Species Presence in Managed Longleaf Pine Landscapes
… U.S. is that of the longleaf pine (<em>Pinus palustris</em>). Bats inhabit key ecological niches in forest ecosystems, including the longleaf pine ecosystem, and can be indicators of ecosystem condition. This study investigated the effects of current forest management practices and …

LONG-TERM OVERSTORY VEGETATION RESPONSES TO PRESCRIBED FIRE MANAGEMENT FOR LONGLEAF PINE AT BIG THICKET NATIONAL PRESERVE
<p>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 …

Effects of Site Preparation, Seed Germination, and Harvest Maturity on Wiregrass Restoration Efforts at Fort Stewart, GA
… within the Atlantic Coastal Plain longleaf pine (Pinus palustris Mill.) ecosystem. Less than 1 million hectares of intact longleaf pine-wiregrass communities remain, due primarily to anthropogenic activities. Wiregrass is a keystone species in the longleaf pine ecosystem, as its presence …

Human Impacts on Fire in De Soto National Forest, Mississippi, U.S.A.
… is a common occurrence in the longleaf pine (<em>Pinus palustris</em>) forests of the Southeast United States. Prescribed fire is used to manage these threatened ecosystems, but information regarding historical fire activity is unknown. My goals were to determine the historical fire regimes in De …

Delineating Metrics of Diversity for a Snake Community in a Rare Ecosystem
… a ~7,000–ha tract of contiguous Longleaf Pine (Pinus palustris) Savanna within the Angelina National Forest (ANF; Angelina and Jasper Cos., TX), over the course of two consecutive snake activity seasons. I quantified the snake species richness, Shannon diversity, and Shannon equitability for the …

Linking The Functional Diversity Of Ectomycorrhizal Fungal Species To Soil Carbon And The Genetics Of A Foundational Tree Species
… ECM fungal community on different genotypes of Pinus palustris. I tested seven enzymes: β-1,4-xylosidase, β-1,4-glucosidase, cellobiohydrolase, phosphatase, β-N-acetylglucosaminidase, peroxidase and phenol oxidase to test my hypothesis that tree genetics directly influences particular …

Influence of fire and habitat on the removal of invasive plant seeds by granivores in longleaf pine savannas
… in upland plant communities, which included Pinus palustris, Aristida stricta, legumes, grasses, and composites (hereafter “upland habitat”), and upland-wetland ecotone communities, which included P. palustris, Acer rubrum, Liriodendron tulipifera, shrubs, cane, and forbs (hereafter “ecotone …

Ecology of Root-Feeding Insect Assemblages in Fire-Manipulated Longleaf Pine-Wiregrass Ecosystems
… insect assemblages in longleaf pine wiregrass (Pinus palustris-Aristida stricta) ecosystems of southwestern Georgia, U.S.A. On a random basis, study sites were burned at least every other year (B), or left unburned (UB) for about 9 years. Fine root productivity and root-feeding insect abundances …

Experimental study of an avian cavity-nesting community: nest webs, nesting ecology, and interspecific interactions
… within the fire-maintained longleaf pine (Pinus palustris) ecosystem at Eglin Air Force Base, Florida. In chapter 1, I provide a background review of the ecology of my study system. In chapter 2, I use nest webs to depict the flow of cavity-creation and use at Eglin. I identified 2 webs …
