Salinity and temperature interactions and their relationship to the microbiology of the estuarine environment

Creator:: Morita, Richard Y., Jones, Larry P., Griffiths, Robert P., and Staley, Thomas E.
Abstract:: An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Activity, composition and structure of soil microbial communities in Savannahshrubs of agroecosystems in semi-arid Senegal

Creator:: Diedhiou, Sire
Abstract:: Piliostigma reticulatum and Guiera senegalensis are two native shrubs that coexist with row crops in parkland systems of the Sahel of Africa. Although permanently green all year around in soil depleted in nutrients and dry for a nine-month period, these shrubs have been largely overlooked. Conventional management of these shrubs...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Design, assessment, and future implications of the Multiple Enzyme Analyzer (MEA), a tool for in-situ monitoring of marine microbial activity

Creator:: Jaeger, Stephanie A.
Abstract:: The microbial loop plays a crucial role in remineralization of organic matter and fuels recycled production in the aquatic environment. The capability of microbes to utilize particular compounds can be examined through their ectoenzyme (found outside the cell) activities using fluorogenic substrate analogs. These catalysts hydrolyze polymers otherwise too large...

Variation in communities of ammonia-oxidizing and denitrifying bacteria in Fennoscandian boreal forest soils

Creator:: Ghimire, Rama D.
Abstract:: The objective of this study was to examine the variation among ammonia-oxidizing and denitrifying communities in soils of a natural Fennoscandian boreal forest and of a forest with a long history of fertilization with different levels of nitrogen (N), and to examine whether there are any changes in the microbial...

Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...

Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

Creator:: Hebel, Cassie L.
Abstract:: Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...
