The Regeneration Niche in Bottomland Hardwood Forests: Tree and Herbaceous Communities Along Interacting Gradients of Flood and Light in East Texas Floodplains
<p>The research contained in this document characterizes environmental niches of bottomland hardwood (BLH) plant species, focusing on how gradients in light availability and flooding shape understory composition and exploring a potential trade-off between shade and flood tolerance. Field surveys …

Reestablishing Diversity in Our Hardwood Forests: A Transplant Study of Five Spring-Flowering Herbs
Herbaceous communities are critical to the functioning of forest ecosystems. They recycle nutrients, help prevent erosion, provide critical microhabitats and maintain biodiversity. In the eastern United States, most hardwood forests are growing on land once entirely cleared or used for some form of …

A comparison of floristic diversity in old-growth versus mid-successional secondary-growth hardwood forests of the White Mountain National Forest, New Hampshire, United States
… little similar effort has focused on understory herbaceous communities. This study conducted large-scale, comprehensive botanical inventories of three old-growth and three mid-successional (80--100 year old) secondary forest stands in New Hampshire's White Mountain National Forest (WMNF). Cluster …

Granivory and Granivores in Native Grasslands and Agropyron Cristatum Stands in the Northern Great Plains
… rates, granivore seed preferences, and ant communities in paired native grasslands and A. cristatum stands. I examined temporal variation in vegetation factors that influence granivory rates. Finally, I determined the relationship between seed size and vertebrate granivore preferences in …

Habitat use and activity patterns of Gopher Tortoises (Gopherus polyphemus) inhabiting military test ranges and forested sandhills at Eglin Air Force Base, Florida
… component of a number of upland ecological communities throughout the southeastern U.S., but populations have experienced significant declines over the past century, largely in conjunction with the loss of longleaf pine (Pinus palustris) forests. Military installations have preserved large …

Vegetation community change over decadal and century scales in the North Carolina piedmont
… survey records, I study presettlement forest communities of the Piedmont and attempt to reconstruct Piedmont forests as they may have been in the time before European arrival. The pattern of successional change in southeastern United States Piedmont forests has been assumed from chronosequence …

The manipulation, introduction and ecology of field layer communities in broadleaved woodlands
… and investigating techniques to enhance the herb communities of secondary woodlands, particularly recently developed urban woodlands, by manipulating existing field layers, enriching them through the introduction of woodland herbs, and by examining aspects of the ecology of selected species which …

Ecological Limitations and Potentials of Artificial Aquatic Systems
… the town, stratified by substrate and season. Communities varied by substrate and season as expected, but did not differ significantly between artificial and natural streams. Instead, both types of streams changed as water flowed from undeveloped desert through town, suggesting that irrigation …
