Developing Nondestructive Techniques for Managing Conflicts Between Fisheries and Double-Crested Cormorant Colonies

Creator:: Suzuki, Yasuko, Roby, Daniel D., Lyons, Donald E., Courtot, Karen N., and Collis, Ken
Abstract:: Double-crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin. Management plans for reducing the size of a large colony on East Sand Island (OR, USA) in the Columbia River estuary are currently being developed. We evaluated...

Tropical forest fragmentation limits pollination of a keystone understory herb

Creator:: Hadley, Adam S., Frey, Sarah J. K., Robinson, W. Douglas, Kress, W. John, and Betts, Matthew G.
Abstract:: Loss of native vegetation cover is thought to be a major driver of declines in pollination success worldwide. However, it is not well known whether reducing the fragmentation of remaining vegetation can ameliorate these negative effects. We tested the independent effects of composition vs. configuration on the reproductive success of...

Colony Connectivity of Pacific Coast Double-Crested Cormorants Based on Post-Breeding Dispersal From the Region’s Largest Colony

Creator:: Courtot, Karen N., Roby, Daniel D., Adkins, Jessica Y., Lyons, Donald E., King, D. Tommy, and Larsen, R. Scott
Abstract:: To reduce conflicts with fish resources, other colonial waterbirds, and damage to habitats, double-crested cormorants (Phalacrocorax auritus) are currently controlled (lethally and non-lethally) throughout much of their range. Concerns are growing over the Pacific Coast's largest double-crested cormorant colony at East Sand Island (ESI), Oregon near the mouth of the...

Closely-related taxa influence woody species discrimination via DNA barcoding: evidence from global forest dynamics plots

Creator:: Pei, Nancai, Erickson, David L., Chen, Bufeng, Jones, Frank A., Ge, Xuejun, Mi, Xiangcheng, Swenson, Nathan G., Zhang, Jin-Long, Huang, Chun-Lin, Ye, Wanhui, Hao, Zhanqing, Hsieh, Chang-Fu, Lum, Shawn, Bourg, Norman A., Parker, John D., Zimmerman, Jess K., McShea, William J., Lopez, Ida C., Sun, I-Fang, Davies, Stuart J., Ma, Keping, and Kress, John
Abstract:: To determine how well DNA barcodes from the chloroplast region perform in forest dynamics plots (FDPs) from global CTFS-ForestGEO network, we analyzed DNA barcoding sequences of 1277 plant species from a wide phylogenetic range (3 FDPs in tropics, 5 in subtropics and 5 in temperate zone) and compared the rates...

Association of hydrophobic organic compounds with dissolved soil organic carbon

Creator:: Ochs, Michael
Abstract:: Volatile hydrophobic compounds (HOCs) brought into soil and sediment systems represent a serious threat to the environment. Dissolved organic carbon (DOC) may exert an important influence over the total aqueous solubility and mobility of organic pollutants through their incorporation into micelles or the formation of soluble complexes. To date, however,...

Zinc tin oxide thin-film transistor circuits

Creator:: Heineck, Daniel Philip
Abstract:: The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

Sustainable construction safety and health rating system

Creator:: Rajendran, Sathyanarayanan
Abstract:: The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...

Water quality impacts of free ranging cattle in semi-arid environments

Creator:: Larsen, Royce E.
Abstract:: The purpose of this study was to evaluate the effects that free ranging cattle have on water quality in semi-arid environments. There were three specific objectives: 1) To determine the concentration and distribution of cattle feces in meadows, riparian zones, and the associated uplands. 2) To determine the fecal deposition...

The Nature of Sulfate Saturation in Oxidized Arc Magmas: Implications for Magmatic Sulfur Budgets

Creator:: Hutchinson, Michael C.
Abstract:: This dissertation is concerned with the behavior of sulfur in intermediate-silicic arc magmas associated with subduction at convergent margins. In particular it focusses on oxidized, sulfur-rich magmas, the conditions at which they might reach sulfate saturation, and implications of sulfate saturation. It is divided into an investigation of natural samples...

Optimization of seasonal irrigation scheduling by genetic algorithms

Creator:: Canpolat, Necati
Abstract:: In this work, we first introduce a novel approach to the long term irrigation scheduling using Genetic Algorithms (GAs). We explore the effectiveness of GAs in the context of optimizing nonlinear crop models and describe application requirements and implementation of the technique. GAs were found to converge quickly to near-optimal...
