(Dissertation) | Litter decomposition is a fundamental process about which a great deal is known, but most knowledge comes from studies of single-species decay. Litter-mixing studies have tested whether monoculture data can be applied to mixed-litter systems and have mainly attempted to detect non-additive effects of litter mixing, which addresses consequences of random species loss.

(Master's Thesis) | Nonpoint source (NPS) pollution is possibly the greatest form of contamination to our nation's waters. Nutrient pollutants, such as nitrate and ammonium, often enter aquatic ecosystems through surface and subsurface hydrological transport that drain agricultural watersheds. The over-abundance of nitrogen within these watersheds is easily transported to receiving stream and rivers, and result in aquatic ecosystem degradation.

Variability in seed arrivals depends on spatial variation in the location and fecundity of adults and on the combined effects of two features of dispersal: 1) dispersal distance, how far from a source seeds are likely to land, and 2) seed clumping, how ônoisyö or unpredictable seed arrivals are at fin e spatial scales.

Response to Soil Microarthropods and Microclimatic Conditions to Two-Age Regeneration in Hardwood Forests in the Southern Appalachians. [dissertation] Athens (GA): University of Georgia. | Graduate Publication
(Dissertation) | Forest stands are harvested on a scale of several hectares, whereas most microarthropods will spend their entire lives within a scale of several meters. Rarely is this mismatch between spatial scales accounted for when examining the response of soil microarthropods to forest harvesting methods, such as two-age regeneration treatments. Microhabitats, i.e. residual trees, coarse woody debris piles, grassy clearings, residual shrubs, coppices, and skid roads, are created or exacerbated by the harvesting process. Microhabitats have been shown to be a determining factor in microarthropod community composition. Microclimatic conditions, including soil temperature, soil moisture, bulk density, and litter depth, are also determinants of microarthropod community composition.

(Dissertation) | Processes operating at early life history stages of trees are thought to foster species diversity, but empirical studies have lagged behind theory in determining which processes maintain forest diversity. For my dissertation, I combine extensive data with statistical modeling to determine interacting effects of seed dispersal, seed dormancy, and density-dependent mortality on species diversity of Southern Appalachian forests.

Factors regulating nitrogen mineralization rates of an oak pine and hardwood forest along an elevation gradient. [thesis] Athens (GA): University of Georgia. | Graduate Publication
(Master's Thesis) | Reaction rates typically decrease with decreasing temperature. Temperature decreases with increasing elevation. Thus, nitrogen (N) mineralization rates are predicted to decrease with increasing elevation. However, N mineralization rates are more than an order of magnitude greater at a high elevation northern hardwood (NH) stand than at a lower elevation Oak Pine stand (OP) at the Coweeta Hydrologic Laboratory in the southern Appalachian mountains, NC. A preliminary experiment tested whether a promoter substance existed in the leachate of the herbs, leaf litter or soils of the NH site, by treating soils with cold water extracts of these components.

Seedling Recruitment in Southern Appalachian Forests: Does Spatial Heterogeneity Maintain Species Diversity? [dissertation] Durham (NC): Duke University. | Graduate Publication
(Dissertation) | Spatial heterogeneity in biotic and abiotic factors is one mechanism proposed to maintain species diversity. In forests, canopy gaps are a major source of environmental heterogeneity, providing for increased light levels that may play a central role in tree regeneration and subsequent patterns of species diversity. While many studies have examined the direct effects of canopy gaps on seedling recruitment, few have considered the interaction of other sources of spatial heterogeneity with canopy gap formation. I examine the potential for spatial heterogeneity in understory cover, mineral resources, moisture, seed and seedling predation, and overstory condition to contribute to species coexistence.

(Dissertation) | The sapling and adult stages of the tree life-cycles are understudied for most species. The resulting knowledge gap hinders our understanding of forest community dynamics and undermines confidence in models currently used to predict forest composition. Here I develop techniques for filling this gap, and apply them at a site in the southern Appalachian Mountains.

[dissertation] Athens (GA): University of Georgia. | Graduate Publication
(Dissertation) | Ecosystems of the world today have been greatly affected by both man-made and natural disturbance events. No matter what the origin, disturbances to an ecosystem typically cause changes in ecosystem properties and function. The overall effects of a disturbance event are often dependent upon the severity of the disturbance. By comparing soil properties both before and following disturbance events on Watershed 55 at the Coweeta Hydrological Laboratory, we were able to examine several soil properties which were likely to be sensitive to disturbances affecting both vegetation and the soil system. The main objectives of this study were to: (1) quantify the effects of rhododendron removal and hurricane windthrow damage upon soil microbial biomass nematode trophic groups, soil phosphorus levels, N-mineralization, and litter decomposition in pre-versus post-disturbance soils, (2) compare these aforementioned variables between three temperate hardwood forested ecosystems (Coweeta, Harvard Forest, and Hubbard Brook) in order to examine changes in soil nutrient levels under differing conditions of temperature, moisture, and litter quality.
