Development of a Structured Adaptive Approach to Klamath Basin Sucker Recovery Planning

Creator:: Barajas, Miguel F.
Abstract:: Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...

Characterization and spatial distribution of particulate organic matter in the Arctic Ocean

Creator:: Corvi, Elizabeth R.
Abstract:: Water samples from the Arctic Ocean were analyzed in order to assess the present nature of particulate organic matter and investigate the effect of climate-driven changes on the ecology of the region. 661 individual surface water samples and 216 samples from CTD casts were collected from the Bering, Chukchi, and...

Analysis of particulate organic matter distribution along surface waters of the California Current

Creator:: Welch, Kylie
Abstract:: Water samples along the Washington, Oregon and California coastline were collected using high resolution sampling and analyzed to determine particulate organic carbon and nitrogen concentrations. Over 28 days during August 2011, nearly 1500 samples were collected aboard the R/V Wecoma (W1108C) using a semi-automated filtration system. Additional subsurface samples were...

A Multivariate Analysis of Pacific Arctic Surface Waters

Creator:: Bryant, Aleesa
Abstract:: The Pacific Arctic is undergoing rapid biogeochemical changes in response to warming air temperatures caused by climate forcing. This is manifesting as changes in seasonal sea ice thickness and sea ice extent, as well as changes in primary production within surface waters. The data and samples analyzed here were collected...

A terrestrial organic matter depocenter on a high-energy margin adjacent to a low-sediment-yield river : the Umpqua River margin, Oregon

Creator:: Hastings, Roxanne H.
Abstract:: Small, mountainous river systems have been increasingly studied due to their importance as sources of fluvial sediment and organic matter to the coastal ocean. Thus far, studies of small, mountainous river systems have focused on rivers with very high sediment loads. The well-studied Eel River dispersal system in northern California...

High-resolution sampling of particulate organic carbon in a coastal upwelling system

Creator:: Holser, Rachel R.
Abstract:: Summertime, wind-driven upwelling off the Oregon coast delivers nutrient rich water to the surface that fuels the autotrophic production of particulate organic carbon (POC). This POC can be transported horizontally by fluid motions and vertically by sinking to the bottom where it can be entrained in the benthic boundary layer...

Computational Investigation on the Effects of Arc Location in Vacuum Arc Remelting

Creator:: Soler, Miguel
Abstract:: Vacuum arc remelting (VAR) is a secondary melting process for exotic alloys. The main purpose of this process is to increase the input ingot’s physical and chemical homogeneity. This is accomplished through the application of a high current that melts the material through the emergence of electrical arcs that induce...

Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

Creator:: Cifuentes Jara, Miguel
Abstract:: Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

Industrial adjustments in American Managerial techniques for developing countries

Creator:: Andrade, Hernan Miguel
Abstract:: The purpose of this study is twofold; first, to describe and analyze the most significant problems encountered by managers of manufacturing plants in developing countries. American managerial techniques are taken as basis of comparison. Second, to suggest approaches and points of view which can be useful to managers and students...

Inheritance of Septoria leaf blotch resistance and the possible influence of heading date and plant height on the disease expression in a winter wheat cross

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: Parental lines, Fi's and segregating populations (F₂, F₃ and BC's) including reciprocals were evaluated under field conditions to determine if genetic resistance per se exists for Septoria Leaf Blotch in a selected winter wheat cross. The experiment was conducted over a three year period with both natural infection and artificial...
