Environmental quality and the spatial distribution of economic activities affect each other in many ways. The primary purpose of this dissertation is to contribute to understanding the complex interrelationship and its policy implications. This dissertation consists of three essays.
The first essay examines the roles that locational amenities and increasing...
A taxonomic study was made on the genera Rhynchophorus and
Dynamis of the weevil family Curculionidae which includes all of the
species known to occur in the world. The bibliography lists all the
important papers published to date on the taxonomy and bionomics of
these weevils. A full synonymy is...
Litter nutrient dynamics contribute significantly to biogeochemical cycling in
forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...
Numerous water supply systems and community based water boards have been created with the aid of international organizations and NGOs in developing countries. These water systems have great potential to improve people’s social life and health in these countries. However, in reality, these water systems are often not effectively managed;...
The properties and evolution of nonlinear internal waves (NLIWs) depend
upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...
A feral pig population on Santa Catalina Island, California, was
studied for 17 months beginning in July 1980. Density was estimated
to be 21 to 34 pigs/km² (95% confidence interval) using capture-recapture
techniques. Dry season home ranges determined from
radio-telemetry data were small and differed significantly between
boars and sows....
This dissertation focuses on the predator-prey relationship between two species of avian predators, Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus), and one of their important prey types, juvenile salmonids (Oncorhynchus spp.), in the Columbia River estuary of Oregon and Washington states during the period 1998 – 2007. I...
This dissertation consists of three essays on meta-analysis, benefit transfer and recreation use valuation. The first two essays were based on the sportsfishing valuation literature in the US and Canada while the third essay was based on a study
site in the Philippines and selected study sites from the US....
Biophysical, socioeconomic and geopolitical pressures from population growth and economic development are leading to an increase in tensions regarding the sharing of water within transboundary basins. Transboundary basins are surface rivers and groundwater resources that are shared among sovereign nations and autonomous regions. This dissertation focuses on surface water in...
This study centered upon two objectives. First, to demonstrate and apply a statistical method, the transfer function, and to test its usefulness in regional economic modeling and regional impact ana1ysis; and second, to obtain a better understanding of the causal relationships among total employment, government employment, lumber and wood products...
