A multi-trophic level examination of recreational impacts on a national wild and scenic river

Creator:: Wright, Kristopher Keith
Abstract:: Initially, components of an aquatic food web were examined to study impacts of recreational use on the aquatic ecology of Quartzville Creek, Oregon in 1995 and 1996. Measurements of the food web components consisted of observations of harlequin ducks (Histrionicus histrionicus), visual counts of the larval caddisfly Dicosmoecus gilvipes, benthic...

From continua to patches : longitudinal patterns in the Middle Fork of the John Day River, Oregon

Creator:: Wright, Kristopher Keith
Abstract:: The Middle Fork John Day River is composed of low gradient, alluvial valley segments separated by constrained, canyon-like reaches, and has a history of multiple land-uses. These factors can alter the physical and biological structure of streams, and disrupt the longitudinal river continuum. I examined habitat, fish, macroinvertebrates, and primary...

Is there an Urban-Rural Divide in Stated Preferences for Protecting an Endangered Species? The Case of the Cook Inlet Beluga Whale

Creator:: Lew, Daniel
Abstract:: General population stated preference surveys are generally drawn from random samples that typically contain a large number of urban households relative to rural households due to the spatial distribution of populations. Given this, it is important to understand and assess whether differences in the preferences and values these two populations...

Estimating Recreation Benefits Through Joint Estimation of Revealed and Stated Preference Discrete Choice Data

Creator:: Lew, Dan and Whitehead, John
Abstract:: We develop econometric models to jointly estimate revealed preference (RP) and stated preference (SP) models of recreational fishing behavior and preferences using survey data from the 2007 Alaska Saltwater Sportfishing Economic Survey. The RP data are from site choice survey questions, and the SP data are from a discrete choice...
