The role of soil-water depletion and plant-moisture stress in soil classification and cambial activity of Douglas-fir

Creator:: Thomas, Byron R.
Abstract:: Relationships between soil-water stress and plant-moisture stress were studied with respect to soil classification and cambial activity in Douglas-fir. The study sites were forested with Douglas-fir and located in McDonald Forest and near Marys Peak in the Oregon Coast Range. Soil-water depletion was followed by the use of gypsum blocks...

Biogeochemical Processing of Freshwater Carbon in the Anthropocene

Creator:: Buser, Jessica Z.
Abstract:: Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...

Learning with Partial Supervision for Clustering and Classification

Creator:: Pei, Yuanli
Abstract:: In the field of machine learning, clustering and classification are two fundamental tasks. Traditionally, clustering is an unsupervised method, where no supervision about the data is available for learning; classification is a supervised task, where fully-labeled data are collected for training a classifier. In some scenarios, however, we may not...

The effects of CI tools and implementation practices on hospital performance

Creator:: Holliday, John W.
Abstract:: Continuous Improvement (CI) is an integral part of hospital administration. This study examined the relationship between five CI variables against six hospital criterion measures of, wait times to prepare a room, patient costs per day, waiting time for lab results, reportable errors, patient satisfaction, and employee satisfaction. The research was...

Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

Creator:: Wang, Lu
Abstract:: Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

Diffusion of Eurasian guarding dogs into American agriculture : an alternative method of predator control

Creator:: Lorenz, Jay R.
Abstract:: The diffusion of livestock guarding dogs into American agriculture provides an example of a developed nation adopting a peasant husbandry practice. Guarding dogs, associated with transhumant husbandry, have been used to protect sheep and other livestock from predators in Eurasia for 2000 years. However, they were virtually unknown by Anglo-American...

The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

Creator:: Kieft, Brandon P.
Abstract:: Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

Chemical and Genetic Investigations of Toxic Freshwater Cyanobacterial Blooms for Improved Monitoring and Understanding of Lake Ecology

Creator:: Collart, Lindsay P.
Abstract:: Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...

Ecology and Environmental Controls of Two Keystone Groups of Oceanic Microorganisms : Diazotrophs and Pathogenic Vibrio

Creator:: Gradoville, Mary Rose
Abstract:: Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

On the abyssal temperatures of the world oceans

Creator:: Olson, Boyd Ellertson
Abstract:: In comparison with solar radiation, the energy of geothermal heat flowing through the sea bottom is extremely small; nevertheless, this energy is not insignificant in the circulation of the bottom water. Calculations indicate that in the deep basins of the South Atlantic the water volume transport necessary to remove this...
