Throughfall variation in a mixed deciduous forest
… were measured in an uneven-aged, mixed deciduous forest in western Virginia from August 6, 1972 to June 19, 1973. Storms were grouped according to leafy (growing) season and leafless (dormant) season for analysis of gross rainfall and throughfall. Average leafy season throughfall was …

Biogeographical And Evolutionary Processes Influencing The Assembly Of Deciduous Forest Plant Communities
… the geographic distribution of an ant-dispersed forest plant, Jeffersonia diphylla, to assess whether the population structure of its geographic range in eastern North America exhibited patterns consistent with a distribution in equilibrium with the environment, or whether the species’ limited …

The Effects of Prescribed Fire on Millipede and Salamander Populations in a Southern Appalachian Deciduous Forest.
<p>Prescribed fire has increased as a forest management practice in southern Appalachia, but investigations into the effects of this silvicultural treatment on non-game wildlife inhabiting the region is limited. This study investigated the effects of prescribed fire on millipede and salamander …

Differential Canopy Leaf Flushing and Site Nitrogen Status Facilitate Invasive Species Establishment in Temperate Deciduous Forest Understories
… and function worldwide. In the temperate forests of the northeastern United States invasive plant species frequently establish and colonize edge environments; however, they are not confined to these areas. In this study, I hypothesized that nonnative species presence would be greatest …

Eastern Deciduous Forest Phenology and Vegetative Vigor Trends From 2000 to 2013, Mammoth Cave National Park, KY
… of short-term climate variability for forests in central Kentucky. Using a Normalized Difference Vegetation Index (NDVI) calculated from MODerate-Resolution Imaging Spectroradiometer (MODIS) instrument data, the photosynthetic activity of vegetation at Mammoth Cave National Park (MACA) …

The Influence of Selection Silviculture Biomass Harvesting on Soil Carbon, Nutrients, and Respiration in a Northern Mixed-Deciduous Forest
… increased recovery of biomass in northern mixed deciduous forests. Several studies suggest that biomass extraction and enhanced decomposer activity can lead to losses of soil C and nutrients, increased nitrification, and reduced soil CO2 efflux (FCO2) from compaction and root senescence. However, …

The Impact of Neighborhood-Based Processes on Demography and a Decline in Species Diversity in a Temperate Deciduous Forest
… species, Acer saccharum (Sugar maple), in a deciduous forest in central Illinois, U.S.A. during 1939--2001. First, the impact of density-dependence, interspecific competition, and disturbance on mortality and recruitment of tree species was evaluated. Second, neighbor-specific transition …

Inhibition of Canopy Tree Seedlings by Thickets of <I>Rhododendron maximum</I> L. (Ericaceae) in an Eastern Deciduous Forest
… covers large areas of the understory in the deciduous forests of the southeastern United States. Thickets of R. maximum are inhibitory to recruitment and regeneration of many understory plants including canopy tree seedlings. By effectively lowering the survivorship of woody species trying to …

Effects of Climate, Forest Structure, Soil Water, & Scale on Biosphere-Atmosphere Gas Exchange in a Great Lakes Mixed-Deciduous Forest
… between the biosphere and atmosphere. Over forested canopies, the physical structure of vegetation interacts with the wind by exerting drag on the flow, thus generating turbulent mixing that is necessary for scalar transport. These interactions occur across a variety of spatio-temporal …

Floristic homogenization and impoverishment : herb layer changes over two decades in deciduous forest patches of the Weser-Elbe region (NW Germany)
… are herb layer plant communities of fragmented forests such as those in the west European lowlands. However, our knowledge about current changes in species diversity and composition in these communities is limited due to a lack of adequate long-term studies. In this thesis, I resurveyed the herb …

Changes in avian diversity and potential invasive seed dispersal post-wildfire in a Southeastern deciduous forest; Flipper Bend Woods, Signal Mountain, Tennessee
In eastern deciduous forests, fire-disturbance and its ecological implications have not been heavily studied. In Tennessee, a recently burned site (2016) presented a unique opportunity to analyze habitat regrowth two-three years after a major wildfire thought to have been worsened by invasive …

Comparative Phylogeography of Eastern Chipmunks and White -Footed Mice: Population Histories Since the Last Glacial Maximum
… urban development compared to sites separated by deciduous forest habitat. Mitochondrial DNA sequences of all P. leucopus indicated that post-glacial expansions into the region did not confound the analysis of microsatellite variation. This study provides important empirical data on the importance …

The effects of accelerated soil acidification on aggrading temperate deciduous forests: The Fernow Experimental Forest Long Term Soil Productivity (LTSP) Study at 13 years
Many temperate forests in the Eastern US are young and have experienced decades of elevated inputs of acidic compounds from the atmosphere. As a result, I used the Fernow Experimental Forest Long Term Soil Productivity (LTSP) experiment near Parsons, WV to determine how ongoing acidic deposition …

The acclimation ability of the shale barren endemic Eriogonum alleni to light and heat
… temperatures higher than the surrounding deciduous forest. A variety of plant species, several of which are rare or endangered, are endemic to the shale barren habitat. One reason proposed fc)r their endemism is that the plants are obligate heliophytes (Keener, 1983). The purpose of this …

The spatial ecology of the Eastern box turtle (Terrapene carolina carolina) in a fragmented landscape in Southeast Tennessee, Hamilton County
… At the landscape level, turtles used eastern deciduous forest and successional habitats and they selected sites with ample ground and canopy cover. These findings can be used to better conserve the habitats and populations of the Eastern Box turtle.

Early Successional Processes of Experimentally-Reclaimed Mine Sites in Eastern Ohio and the Restoration of American Chestnut
… throughout the Appalachian region of the Eastern Deciduous Forest. Federal law has required reclamation of mined sites to mitigate environmental hazards since the late 1970s. However, the methods typically utilized do not allow for a return to the forest cover found on these sites prior to mining. …
