The Lubbock Chamber Of Commerce, The New Deal, And The Ropesville Resettlement Project, William Clayson
The Lubbock Chamber Of Commerce, The New Deal, And The Ropesville Resettlement Project, William Clayson
Great Plains Quarterly (through 2013)
US Highway 62 crosses the town of Ropesville, population 480, between Lubbock and Brownfield on the South Plains of Texas. To the north and west of town, scattered among the suburban-style homes of contemporary farmers, stand several dozen small cottages of identical design. Some are still occupied, many nothing more than ruins, and a few have been added on to, stuccoed, or provided a screened porch. All are surrounded by cotton fields and most are accompanied by ramshackle outbuildings, rusted tractors, dormant windmills, and sealed irrigation wells. These farmsteads are the remains of a rural community project constructed by the …
Humanitarians On The Frontier Examples From Northeastern Logan County, Oklahoma Territory, Leslie Hewes
Humanitarians On The Frontier Examples From Northeastern Logan County, Oklahoma Territory, Leslie Hewes
Great Plains Quarterly (through 2013)
Scholars have studied the frontier of Euro-North American settlement from a number of perspectives. James C. Malin and Allen G. Bogue, for example, have examined the turnover of population in the newer parts of the United States. Walter Prescott Webb considered the Great Plains a strange kind of country for most of its pioneers, branding them as woodsmen out of place in the western part of the great interior grassland. Paul W. Gates has emphasized speculation and an incongruous land system as marking the American new lands, while James K. Hastings has recognized cooperative endeavor, a kind of sharing, as …

Identification and assessment of the relative importance of factors affecting duckling growth and survival are essential for effective management of mallards on breeding areas. For each of 3 years (1993-95), we placed Fl-generation wild mallard (Anas platyrhynchos) females on experimental wetlands and allowed them to mate, nest, and rear broods for 17 days. We manipulated invertebrate densities by introducing fathead minnows (Pimephales promelas) at high densities in half of the wetlands on which broods were confined. Day- 17 body mass of surviving ducklings (n = 183) was greater for ducklings that were heavier at hatch; the …

The scent-station survey method has been widely used to estimate trends in carnivore abundance. However, statistical properties of scent-station data are poorly understood, and the relation between scent- station indices and carnivore abundance has not been adequately evaluated. We assessed properties of scent- station indices by analyzing data collected in Minnesota during 1986-93. Visits to stations separated by < 2 km were correlated for all species because individual carnivores sometimes visited several stations in succession. Thus, visits to stations had an intractable statistical distribution. Dichotomizing results for lines of 10 stations (0 or ≥ 1 visits) produced binomially distributed data that were robust to multiple visits by individuals. We abandoned 2-way comparisons among years in favor of tests for population trend, which are less susceptible to bias, and analyzed results separately for biogeographic sections of Minnesota because trends differed among sections. Before drawing inferences about carnivore population trends, we reevaluated published validation experiments. Results implicated low statistical power and confounding as possible explanations for equivocal or conflicting results of validation efforts. Long-term trends in visitation rates probably reflect real changes in populations, but poor spatial and temporal resolution, susceptibility to confounding, and low statistical power limit the usefulness of this survey method.
