Globally, the number of threatened species is increasing and conserving them is a high priority to the scientific community. Assessing the status of these protected species is challenging due to missing, contested, and or contradictory data streams. Integrated models (IMs) provide a statistical framework for combining disparate data sources to...
This research deals with the problem of soil erosion in Cypress
Creek basin in West Tennessee and farmer participation in public
conservation programs. The study area is marginal to the
Tennessee Valley, a region identified in the 1930's as having a serious
agricultural soil erosion problem. The four voluntary programs...
Geotextiles are synthetic fabrics which may be substituted for
graded aggregate to protect ocean and coastal structures from erosion
and soil instability adjacent to the structure. They are commonly
used as a filter and as a structural membrane between an undisturbed
sediment surface below and an erosion resistant coarse aggregate...
This dissertation consists of three papers on the use of incentives for conservation of endangered species on private land. The first paper examines incentives based on providing landowners with assurances regarding future regulation in exchange for their participation in a conservation agreement. The second and third papers are empirical analyses...
The nonlinear Schrödinger equation is a well-known partial differential equation that provides a successful model in nonlinear optic theory, as well as other applications. In this dissertation, following a survey of mathematical literature, the geometric theory of differential equations is applied to the nonlinear Schrödinger equation. The main result of...
Energy expenditures, perceived family well being, and energy
conservation actions were analyzed by family composition and level of
income. Data were from a three state subsample (Arizona, Colorado,
and Oregon; N = 2,633) of a larger stratified random sample of
households in the Western United States. Data were collected in...
Management of deer populations is directed toward multiple
objectives. Deer populations on public and private lands belong to the
public and thus management is a political process. Four components
for an effective management system for deer populations are identified.
These are the set of objectives relating to the resource, the...
Soil erosion research in the fields of agronomy, soils science
and mechanics, agricultural engineering, hydrology, climatology, and
other scientific disciplines has economic dimensions. In general,
measurable and, at times, significant economic effects are
associated with the effects of erosion in the other disciplines.
Interactions between climate, soils, hydrology, and tillage...
