The Genomic Capabilities of Microbial Communities Track Seasonal Variation in Arctic Lagoons

Creator:: Baker, Kristina D.
Abstract:: The lagoons spanning Alaska’s Beaufort Sea coast provide a unique habitat for arctic wildlife. These lagoons and the food webs they support face extreme seasonality with nine months of ice cover followed by a spring thaw that pulses a large amount of freshwater and nutrients into the lagoons. Bacteria link...

Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

Creator:: Curtis, Jenna R.
Abstract:: Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...

Orbiting the Genus of False Units: Dynamics of Phage Genomes and Nematode Microbiomes Associated with Pseudomonas spp.

Creator:: Ha, Anh D.
Abstract:: Pseudomonas is a diverse, ubiquitous, and widely studied genus of bacteria. As Pseudomonas species occupy a wide range of niches in the ecosystem, they have made remarkable biological impacts. Better understanding of Pseudomonas biology, genetic diversity, and functional interactions with other organisms and the environment will provide valuable insights into...

Impacts of microbial chemical interactions on marine plankton physiology

Creator:: Moore, Eric R.
Abstract:: The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...

Host and Pathogen Contributions to the Populus–Sphaerulina Pathosystem

Creator:: Mondron Kyle T.
Abstract:: Sphaerulina musiva is a fungal pathogen that causes Septoria leaf spot and stem canker on susceptible Populus species and hybrids. In this thesis, host and pathogen contributions to Septoria stem canker disease were explored through: 1) a greenhouse study associating Septoria stem canker phenotypes with molecular markers from a genetic...

Genome Wide Association Mapping for Abiotic and Biotic Stresses in Barley (Hordeum vulgare L.) Using Diverse Arrays of Doubled Haploids Derived From Intercrossing Exotic and Adapted Germplasm

Creator:: Hernandez, Javier
Abstract:: The following dissertation consists of six sections: a general introduction, three manuscripts, a general conclusion, and an overall bibliography. The three manuscripts report on: (1) identifying genetic interactions in diverse germplasm developed during introgression of a major gene conferring resistance to stem rust (Puccinia graminis f. sp. tritici), (2) mapping...

Effect of Agronomically Selenium Biofortified Hay on Oxidative Status, Metabolic and Inflammatory Biomarkers, and Immune Response of Transition Primiparous Dairy Cows and Se Transfer and Glutathione Peroxidase Activity in their Calves

Creator:: Jaaf, Shana S.
Abstract:: During the peripartum period (3 weeks before through 3 weeks after calving, a.k.a. “transition”), high producing dairy cows experience, among others, , oxidative stress and immune suppression that compromise performance and increased incidence of diseases.Among trace minerals, supplementation of Selenium (Se) can help to improve the transition by enhancing glutathione...

A Dive into the Pacific Fish Microbiome: Exploration of Antibiotics from a Unique Ecosystem

Creator:: Austin, Molly C.
Abstract:: With the rise of resistant bacterial pathogens, currently prescribed antibiotics are rendered useless. In recent years, marine natural products (MNPs) have emerged as novel sources for drug leads. The ocean is a complex environment where marine animals cohabitate with many, and sometimes harmful microorganisms and viruses, but resist infections. Developed...

The effects of X-ray CT scanning on microbial communities in sediment cores

Creator:: Ewton, Erica
Abstract:: Using X-ray computed tomography (CT) scanning to characterize the physical characteristics of soil and sediment cores allows scientists to observe and analyze stratigraphy without destroying the integrity of different layers. Microbiologists often work with geologists to characterize the microbial communities in such cores; however, X-rays are known to be destructive...

It’s in Their Bones: Ecological Drivers of Kemp’s Ridley Sea Turtle (Lepidochelys kempii) Somatic Growth and Population Dynamics

Creator:: Ramirez, Matthew D.
Abstract:: Somatic growth variation manifests from the cumulative effects of a suite of biological, ecological, and environmental processes and can have profound effects on individual fitness and species population dynamics. As ectotherms whose growth dynamics are greatly influenced by environmental factors, sea turtles display considerable variation in somatic growth within and...
