The vascular flora of the Lula Lake land trust on Lookout Mountain in Walker County, Georgia and a biogeographical analysis of the Coastal Plain element on the Cumberland Plateau
… Plateau was compared to the surrounding physiographic provinces using the legacy database. This comparison indicated a significantly higher proportion of Coastal Plain endemics in the Cumberland Plateau than surrounding physiographic provinces.

Assessment of Genetic Variation of Acer rubrum L. and Liriodendron tulipifera L. Populations in Unmanaged Forests of the Southeast United States
… diversity of these species in contrasting physiographic provinces. AFLP was performed using five primer combinations on samples collected from six unmanaged populations of each species in the Mountains and Coastal Plain of the Southeastern U.S. Wood density was determined using an X-ray …

The Physiography of Canada
<p>The physiographic features of Canada have a complex history which involve a Precambrian peneplain, followed by a long period of sedimentation interrupted in places by diastrophic events, and finally extensive glaciation. Since the turn of the nineteenth century several men have proposed …

Abundance, Distribution, and Geometry of Naturally Occurring Macropores in Stream Banks
… in the banks of 20 streams across five physiographic provinces in the Eastern United States. We identified a total of 1,748 macropores, which were present in all 20 streams, with 3.8 cm average width, 3.3 cm average height, 11.5 cm average depth, and 27.9 cm average height above water …

Quantifying Properties and Variability of Expansive Soils in Selected Map Units
A study of 12 expansive soils in four major physiographic provinces in Virginia was initiated to examine and quantify the relationship between shrink-swell potential, shrink-swell indices, and soil properties. The mineralogy classes, soil series, and (physiographic provinces, parent materials) …

Food habits of the Allegheny woodrat (Neotoma magister )
… in the Ridge and Valley and Allegheny Plateau physiographic provinces of West Virginia and Virginia using microhistological techniques. In the Allegheny Plateau, the top 5 food items were fungi, blueberries ( Vaccinium spp.), acorns (Quercus spp.), ferns ( Dryopteris spp.), and lichens. In the …

Tectonic and sedimentary history of the Mid-Natal Valley (S.W. Indian Ocean)
… basin morphology is defined by five major physiographic provinces: continental shelf and slope, Tugela Cone, Central Terrace, Mozambique Ridge and deep basin plain. Thinned (20-25 km) continental crust, attenuated and subsided in response to Gondwana rifting and drifting, underlies the …

Geospatial and statistical foundations for streamflow synthesis in West Virginia
… in the Allegheny plateau and Valley and Ridge physiographic provinces.

The Appalachian cultural landscape along the New River
… Two explains the physical setting of the four physiographic provinces through which the New River flows. Chapter Three briefly gives an overview of the historical social context of the New River Corridor. Chapter Four describes the eleven sites surveyed as part of this research. The methods of …

Graphical and digital slope stability analyses for Giles County, Virginia
… province and can be adapted to other similar physiographic provinces. Both the slope map and the regional slope stability map can be produced graphically or digitally. The graphical method is inexpensive and fast when used to examine the detailed slope stability of a small area (7.5 minute …

Morphological, Molecular, and Biogeographical Variation within the Imperiled Virginia Spiraea
… the southern Blue Ridge and Appalachian Plateau physiographic provinces. Populations of S. virginiana are found restricted to scoured sections of high gradient streams within the Ohio River drainage. Present evidence indicates the species is reproducing asexually, most probably through the …

Characterization of Vascular Plant Species Composition and Relative Abundance in Southern Appalachian Mixed-Oak Forests
… in the Ridge and Valley and Allegheny Mountain physiographic provinces of Southwestern Virginia and West Virginia to address questions concerning the variability in species composition, richness, and relative abundance of vascular plant species in those communities. All forest strata were …

Growth Correlates of Several Lotic Fishes
… 2002 and 2003. Study sites represented all physiographic provinces in South Dakota and a variety of riverine conditions. Fish studied are common to low order warm water streams and have wide distributions. Mean back-calculated total length at age was estimated from scale annuli for creek …

Evaluation of Nutrient and Pathogen Losses From Various Poultry Litter Storage Methods
… in both the Ridge and Valley and the Piedmont physiographic provinces, with both surface and subsurface flows analyzed. An observational study, where subsurface water was sampled for a nine-month period was conducted using six litter sheds, three in each of the above provinces. Samples were …

Characterizing and modeling wet stream length dynamics in Appalachian headwaters
… I mapped wet stream length in four Appalachian physiographic provinces--the Appalachian Plateau, Blue Ridge, New England, and Valley and Ridge--to characterize seasonal expansion and contraction of the wet network at a broad, regional scale. Conversely, most existing field studies of stream …

Performance of northern red oak (Quercus rubra) underplantings under five management regimes and across existing environmental gradients
… regimes across the environmental gradients of physiographic province, aspect, and fencing levels. Management regimes included 1) control sites, 2) a single prescribed burn, 3) repeat prescribed burns 5) diameter-limit cuts and 4) the seedcut of a shelterwood harvest. Physiographic provinces …

Distribution and Dynamics of the Evergreen Understory Layer in Central Appalachian Highland Forests
… in the Ridge and Valley and Allegheny Plateau physiographic provinces in the mid-Atlantic Highlands using plot data, remote sensing, dendrochronology, and modeling. First, leaf-off satellite remote sensing and topographic data were applied to map the spatial extent and distribution of R. …

Phosphorus Losses in Runoff from Virginia Soils
… P vs runoff DRP relationships varied between physiographic provinces. Generally, the Coastal Plain soils resulted in a higher runoff DRP concentration for a given soil P level compared to Piedmont and Ridge and Valley soils. However, soil M3-P/Al resulted in one relationship with DRP for all …

Assessing the Contamination Risk of Private Well Water Supplies in Virginia
… of Virginia was analyzed, followed by the five physiographic provinces of Virginia: the Blue Ridge, Coastal Plain, Cumberland Plateau, Ridge & Valley, and Piedmont. Ultimately, Louisa County was investigated to evaluate the possibility that better models could be developed using smaller land …
