Effects of the Recreational Fee Demonstration Program on backcountry users in Grand Canyon and Everglades National Parks

Creator:: Leahy, Jessica E.
Abstract:: Since the Recreational Fee Demonstration Program was approved in 1996, allowing public land management agencies to collect and retain recreation user fees, several research studies have gathered opinions and attitudes from different groups of recreation users. One particular group, backcountry users of National Parks, had yet to be included. This...

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

Water movement in the stem xylem in relation to xylem specific conductivity in four hardwood species

Creator:: Fallas-Cedeño, Lottie
Abstract:: In deciduous species, water exits stems mainly through leaf traces attached to the outer growth ring and yet we know that water ascends throughout the entire cross-section of the sapwood. There is an increasing amount of information on sap flow and sapwood hydraulic properties from separate studies, but little information...

The Effect of Downed-trees on Harvesting Productivity and Costs in Beetle-killed Stands

Creator:: Kim, Yaejun
Abstract:: The mountain pine beetle has impacted over 5 million hectares of pine forests in the Rocky Mountains region in the United States. Although some beetle-killed stands are available for salvage harvesting, there are many uncertainties in harvesting beetle-killed stands including safety, costs, recoverable products and their values. These uncertainties impose...

The experiences of middle-level Chinese female adult immigrants working at west coast community and technical colleges

Creator:: Zhou, Lin
Abstract:: Community and technical colleges in the United States are experiencing an expansion of racial and ethnic diversity in students, faculty, and administrators. From 1996 to 2006, the number of Asian female college students increased 55.3%, from 13,184 to 20,477. The number of Asian male students increased 48.9%, from 9,731 to...

The Relationship Between Immigrant Status and Secondary and Postsecondary Attainment in Secondary Students

Creator:: Haviland, Samantha L.
Abstract:: The American School Counseling Association’s Code of Ethics states that counselors and counselor trainees must be competent providers of multicultural counseling, able to practice effectively with clients whose identities differ from their own. Pre-service school counselors receive very little training around immigration status and how to work with clients who...

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Toxicity of Fungal Pigments from Chlorociboria spp. and Scytalidium spp.

Creator:: Almurshidi, Badria H.
Abstract:: Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...

Effects of release from suppression on hydraulic architecture, photosynthetic capacity and functional wood characteristics in Douglas-fir and western hemlock

Creator:: Renninger, Heidi
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a shade intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade tolerant species, were compared to learn more about the temporal pattern of release from suppression in both species, whether hydraulic architecture or photosynthetic capacity constrain release and how wood functional properties change...
