Late Pleistocene Climate, Vegetation, And Fire History From A Southern Appalachian Bog, Whiteoak Bottoms, Nantahala National Forest, North Carolina, U.S.A., Mathew Stephen Boehm
Late Pleistocene Climate, Vegetation, And Fire History From A Southern Appalachian Bog, Whiteoak Bottoms, Nantahala National Forest, North Carolina, U.S.A., Mathew Stephen Boehm
Masters Theses
I examined loss-on-ignition, pollen, and charcoal evidence of climate, vegetation, and fire history at Whiteoak Bottoms (35º04’44”N, 83º31’50”W; 1032 m elevation), a peat-forming wetland located along the Nantahala River in western North Carolina. Previous research by J. McDonald and D. Leigh revealed that this wetland formed in a paleochannel of the Nantahala River between 15,000 and 14,000 cal yr BP. I obtained additional AMS radiocarbon dates, carried out high-resolution loss-on-ignition analysis, and examined pollen and microscopic charcoal assemblages in a 157-cm sediment core from the previous study. Radiocarbon dates and stratigraphic analyses indicate that much of the Holocene is missing …
Fire Regimes Of Lower-Elevation Forests In Great Smoky Mountains National Park, Tennessee, U.S.A., Lisa Battaile Laforest
Fire Regimes Of Lower-Elevation Forests In Great Smoky Mountains National Park, Tennessee, U.S.A., Lisa Battaile Laforest
Doctoral Dissertations
Disturbance is a natural part of any forest ecosystem. When disturbance regimes are altered, the forest stands will reflect those changes. Southern Appalachian xeric pine-oak woodlands are one forest type that has experienced such change, primarily in the form of fire suppression. The western side of Great Smoky Mountains National Park contains stands of large trees that escaped earlier intensive logging, show evidence of past fire, and provide an ideal setting for reconstructing stand histories. For three lower-elevation (ca. 500 m ASL) study sites, I used crossdated yellow pine tree-ring chronologies and records from cross-sections taken from living and dead …
Response Of Inland Lakes To Climate Change Across The Tibetan Plateau Investigated Using Landsat And Icesat Data, Zewen Liu
Masters Theses
The Tibetan Plateau experienced tremendous climate change during the past four decades. Due to the large size, widely distribution of cryosphere, and diverse landforms, different parts of the plateau may experience different climate and cryosphere changing patterns. The changes of inland lakes within the plateau are important indicators of climate change as these lakes are fed by precipitation, permafrost degradation, and glacier melting that are all sensitive to climate change. To examine the spatial and temporal differences of lake variations across the Tibetan Plateau, Landsat images and ICESat/GLAS altimetry data were used to extract the changes in surface areas of …
Reconstruction Of Fire History In The National Key Deer Refuge, Monroe County, Florida, U.S.A.: The Palmetto Pond Macroscopic Charcoal Record, Desiree Lynn Kocis
Reconstruction Of Fire History In The National Key Deer Refuge, Monroe County, Florida, U.S.A.: The Palmetto Pond Macroscopic Charcoal Record, Desiree Lynn Kocis
Masters Theses
The pine rocklands in the Lower Florida Keys are considered endangered because of rises in sea level, urbanization, and human impacts on the natural fire regime. Macroscopic charcoal in a sediment core recovered from Palmetto Pond (24°41’45.15”N, 81°19’43.84”W) in 2010 was examined in contiguous 1-cm intervals to reconstruct Late Holocene fire history. Palmetto Pond is a shallow freshwater solution hole located within the pine rocklands of No Name Key in Monroe County, Florida. Radiocarbon dating of plant material at 247 cm depth in the Palmetto Pond profile indicates the sediment record extends back to ca. 4500 cal yr BP. Charcoal …
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Masters Theses
Many organizations demand that current water resource issues necessitate improved stream network mapping for more accurate and reliable watershed analysis and modeling results, which can ultimately enable better management and policy decisions. Stream network data from the National Hydrography Dataset Plus (NHDPlus) and derived from Light Detection and Ranging (LIDAR) are each widely accepted to be of superior quality compared to many other conventional datasets. Each dataset indicates potential to improve a wide range of water resource applications; NHDPlus for its high spatial accuracy and functionality, and LIDAR-derived networks for their high resolutions. NHDPlus is publicly available and widely used; …
