An inventory and mapping of cliffs within the South Cumberland Plateau region of Tennessee
… that permeate Tennessee’s South Cumberland Plateau (SCP) significantly influence the development, economy, and ecology of the region, yet little effort has been made to quantify these geophysical features. This study examined the use of LiDAR-derived digital elevation models (DEMs) to (1) …

Physical and Chemical Parameters of Common Soils in the Central Plateau Region of Haiti
… rate seen in the country today. The Central Plateau of Haiti is a mountainous region in which a majority of the population is rural and practices subsistence agriculture on hillsides and steeply-sloping land. Essential plant nutrients, such as nitrogen (N) and phosphorus (P), are commonly a …

The dietary mineral content of Claytonia lanceolata corms from multiple populations across the Columbia Plateau region of North America
… we sampled 12 populations across the Columbia Plateau region of North America. We resampled six populations about 30 days after our initial harvest. Corms were assayed for dietary mineral and toxic metal content using standard ICP-OES methods. We found that a single serving of corms (100 g …

Effects of acid mine drainage on limnological conditions and fish assemblages in the Cumberland Plateau region of the North Chickamauga Creek System, Tennessee
… problem in Appalachian streams. The Cumberland Plateau (Southwestern Appalachians ecoregion) portion of North Chickamauga Creek (NCC), a fourth-order tributary to the Tennessee River (Tennessee), has been impacted by decades of AMD from active and abandoned coal mines. I assessed stream …

An Approach to Analyzing and Predicting Force-extension Curves of Nucleic Acids
… stretching experiments reveal a distinct plateau region in force-extension curves of nucleic acids such as long double-stranded deoxyribonucleic acids (DNA) and ribonucleic acids (RNA). The dissertation comprises two parts. In the first part, we propose an approach to help analyze polymer …

Climate and habitat reconstruction of hominid sites in northern China with paleosol stable isotopes
The environment of early hominids in the Loess Plateau region of China is a highly debated subject. Interpretations of past habitats and climates derived from fossil faunal and floral assemblages, paleosols, and geochemistry are often contradictory. In order to understand paleoenvironments and the …

A Multi-Millennial Drought Reconstruction for West-Central New Mexico Using Rocky Mountain Juniper (<i>Juniperus scopulorum</i>, Sarg.)
… hydroclimatic proxy records in the Colorado Plateau region spanning the time period (16<sup>th</sup> century and 2<sup>nd</sup> century megadroughts). By ranking the extreme drought events by magnitude, duration, intensity, and overall score, the most extreme drought events of this record are …

Shoulder to the wind : a lyrical evocation of the Bogong High Plains
… the rocks and creatures and winds of the high plateau region of Australia’s south-east corner. Within this elongated spine of high country rise the Bogong High Plains, a series of peaks and sub-alpine grasslands bordered by forests of snow gum and alpine ash. These High Plains are the subject …

The photophysical characterisation of a fluorescence-based immunoassay for the detection of gonadotropin-releasing hormone, type-1 (GnRH-I)
… Specifically, values extracted from the plateau region of the time-resolved anisotropy decay curves are used to estimate the amount of free and bound [des-pGlu¹]-LH-RH-Acp-FITC and comment on the presence of interference processes in the assay. Furthermore, disruption to a system of …

Are the Old Ways New Again?: Local Farmers Practicing Civic Agriculture in Southwest Missouri
… food” movements on farmers in the Springfield Plateau region of the Missouri Ozarks. Specifically, I investigated whether these local food movements are bringing about a re-emergence of traditional family farms once prevalent before the adoption of conventional agriculture, or are these …

Supra-Characteristic-Frequency Response in Gerbil Auditory Nerve Frequency Tuning Curves
… but the ANF had appeared to be unresponsive to a plateau mode of BM motion that occurs at frequencies above an ANF's characteristic frequency (CF). We recorded ANF responses from the gerbil, concentrating on this supra-CF region. We observed a supra-CF plateau in ANF responses at high stimulus …

Regional Deformation and Dynamic Processes of the Southern Puna Plateau, Central Andes
The southern Puna Plateau of the central Andes offers an excellent opportunity to (1) advance our understanding in orogenic models for non-collisional mountain belts, (2) test Earth’s upper-crustal responses to lower lithospheric processes, and (3) explore uses of low-temperature thermochronology …

Effects of Prior Defoliation on the Timing of Life Cycle Events and Susceptibility to Natural Enemies of a Host Specific Gall-Former
… fusiformis, a live oak endemic to the Edwards Plateau region of central Texas. Comparisons of these patterns document an apparent shift in the timing of B. treatae emergence (Past: Oct.-Dec., Recent: Dec.-Mar.) and survivorship (Past: 0-50%, Recent: 0-13%) in the presence of natural enemies. …

Swimming in slime
… forcing yields a swimmer shape that has a plateau region following by a large spike region. It is found that there exists an optimal forcing that will yield a maximum swimming speed. Next, we solve the problem for moderate forcing amplitudes for viscoelastic shear thickening and shear …

Spatial Trends of Non-Point Pollutants in Bottom Sediment of Lake Springfield, Southwest Missouri
… cooling water for power production in the Ozarks Plateau region. The water quality in the James River basin is impaired in some reaches by nutrients and metals from non-point agricultural and urban pollutants. A GIS-based approach to environmental monitoring is used to collect, map, and evaluate …

Sediment chemistry as an archive of provenance and weathering in the Mekong River Basin
… over millions of years. Tectonically active regions, such as the sub-Himalayan region, are considered a hotspot of silicate weathering and key sites for understanding weathering processes. Rivers, as a carrier of eroded and weathered materials, provide a primary archive for the study of …

Non-game Birds in Relation to habitat Variation on South Dakota Wetlands
… and 5 species occurred most frequently in this region: great blue heron, black-crowned night heron, green heron, sora and American avocet. The willet, marbled godwit and Wilson's phalarope occurred most frequently in the Missouri Coteau; red-winged blackbird and lesser yellowlegs in the Southern …

Natural Environmental Gradients Predict The Microhabitat Use, Fine-Scale Distribution, And Abundance Of Three Woodland Salamanders In An Old-Growth Forest
… a ca. 42 ha old‐growth forest in the Cumberland Plateau region of southeastern Kentucky. This study finds that patterns of microhabitat use, occupancy, and abundance of P. richmondi and kentucki reflected physiological restraints associated with desiccation vulnerability and thermo‐osmoregulatory …

Novel Discoveries About the Spin-Crossover Transition in Schiff-Base Ferric Complexes
… (mu)(,eff)/Fe vs. temperature curves exhibits plateau regions. For the latter case the transition is incomplete and in a certain temperature range the (mu)(,eff)/Fe doe not change or changes very slowly. Mossbauer and EPR spectroscopies indicate that, regardless of the type of (mu)(,eff)/Fe vs. …
