The effects of Bacillus thuringiensis var. israelensis (Bti) on chironomid production was assessed in the New River in southern West Virginia. Production was measured in a year without Bti treatment (1987) and a year with treatment (1988). Sampling was conducted from June through November at Sandstone Falls, 16 km below Bluestone Dam in Summers County. Sampling was restricted to rock outcrops covered with Podostemum (river weed). Samples were collected at 2- wk intervals with a quantitative device that delineates an area of 0.01 m². Three species belonging to two genera accounted for about two-thirds of chironomid production in both years. Cohort production intervals were estimated to be 27 d for both species of Cricotopus and 20 d for P. convictum. Total chironomid production from June through November 1987 was 10.8 g/m² and during the same period in 1988 was 33.8 g/m². In 1987, the production of C. bicinctus and Cc. politus was 4.09 g/m² (38% of total chironomid production), and production of P. convictum was 2.46 g/m² (23%). In 1988, the production of C. bicinctus and C. politus was 12.39 g/m² (37%), and production of P. convictum was 11.38 g/m² (34%). Bti treatments caused no adverse effect on chironomid production in 1988, because the same species were dominant and their production was 3X higher. In addition, density and mean individual biomass were greater in 1988 than in 1987. The production increase in 1988 was probably related to environmental factors other than Bti treatments, such as discharge and Podostemum standing stock. / Master of Science

Much of the bedrock surface of the Southern Appalachian Valley and Ridge Province is covered by a veneer of surficiaI deposits classified as alluvium, colluvium, and residuum. In this investigation the surficial geology of a 60-km² area of the New River drainage system was mapped at a scale of 1:24,000. The area is located within the Eggleston and Newport 7 1/2-minute topographic quadrangles in Giles County, southwest Virginia. The data derived from mapping the surficial geology (particularly alluvial deposits), in conjunction with other field observations and with heavy-mineral analyses, are interpreted in terms of provenance, depositional environment (or accumulation), and preservation of the surficial deposits. In addition, these data are applied to an interpretation of the evolution of the New River drainage in the Valley and Ridge Province during the latter half of the Neogene. The areal distribution of the surficial materials indicates that in a humid, temperate climate deposits of surficial materials tend to be preserved if they overlie carbonate bedrock which weathers chemically but tend to be eroded from shale and sandstone bedrock which weathers mechanically. In carbonate terrains where surface runoff is minimal, surficial materials are let down in place by solution and have been accumulating in a piecemeal fashion over a time period which in some areas may include all of Cenozoic time. Analysis of the transparent heavy-mineral assemblages contained in the modern alluvium and older alluvial deposits of the area indicates that radiation-damaged zircon (intermediate and metamict) is unstable under conditions of subaerial weathering. Earlier workers have suggested that zircon is dissolved by acid ground water. This study supports these earlier suggestions and further demonstrates in a semiquantitative manner that the solution rate of radiation-damaged zircon may be a linear function of time as measured against either tourmaline er normal zircon. The estimated period of time over which the solution rate of zircon appears . to be lil1ear is on the order of 10 m.y. The areal distribution and lithology of alluvial deposits provide evidence which can be used to reconstruct the late Cenozoic evolution of part of the New River drainage system within the Valley and Ridge Province. These data, in conjunction with assumptions involving lithologic and structural variations within the stratigraphic section which has been removed by erosion, suggest that the James and Roanoke Rivers have captured three northeastern tributaries of the New River during the latter half of the Neogene. Within this time period no evidence was found of major changes in the course of the New River itself (except for meander loops) between Radford and Narrows. / Ed. D.

This theses compares the benefits of energy self reliance strategies with the benefits of industrial development strategies to determine which strategies create greater benefits as a method of economic development. A critical factor, which is examined, is the probability of success for industrial development strategies as opposed to the near certain benefits from the self-reliance strategies. The methodology employs a Virginia input-output model using a regional purchase coefficient technique to regionalize the model for the New River Valley Region of Virginia. The strategies are developed based on two distinct expenditure levels, acting as resource constraints on the strategy selection, in order to compare the return on additional expenditures. / Master of Science
