Biotic and Abiotic Drivers of Plant-Pollinator Interaction Rewiring
… I present two observational studies exploring drivers of interaction variation, followed by an experiment in which I demonstrate the effect of changing plant-pollinator interactions. First, I use a structural equation modeling framework to demonstrate that temperature variation and plant …

Examination of Abiotic Drivers and Their Influence on Spartina alterniflora Biomass over a Twenty-eight Year Period Using Landsat 5 TM Satellite Imagery of the Central Georgia Coast
We examined the influence of abiotic drivers on inter-annual and phenological patterns of aboveground biomass for Marsh Cordgrass, Spartina alterniflora, on the Central Georgia Coast. The linkages between drivers and plant response via soil edaphic factors are captured in our graphical conceptual …

Using spatial methods to analyse anthropogenic predation risk and movement ecology of white-tailed deer (Odocoileus virginianus)
… human hunters in combination with the biotic and abiotic drivers of predation risk and flight response. Giving wildlife managers greater understanding to influence deer populations, and landscapes, in the future.

Seasonal dynamics of edaphic bacterial communities in the hyper-arid Namib desert
… and magnesium were identified as significant abiotic drivers of community temporal dynamics. β diversity was found to increase over time, while the environment remained relatively static. These findings support previous observations that desert communities are likely structured by stochastic …

Seasonal dynamics of edaphic bacterial communities in the hyper-arid namib desert
… and magnesium were identified as significant abiotic drivers of community temporal dynamics. β diversity was found to increase over time, while the environment remained relatively static. These findings support previous observations that desert communities are likely structured by stochastic …

Bridging prairie restoration and regenerative agriculture with compost tea / the rocket incident: post-fire soil microbe recovery on the Eastern Washington University restoration site
… Hill position and aspect were the major drivers of both bacterial and nematode community composition in the field, and these differences were not well explained by soil moisture or soil organic matter content. These results indicate avenues of further research into the circumstances in …

Molecular characterization of microbial interactions with labile dissolved organic matter
… of microbe-DOM interactions and the biotic and abiotic drivers of those interactions. This thesis addresses those challenges and questions. In Chapter 2, I explore the compound-specific uptake of metabolites by the copiotrophic gamma-proteobacterium Alteromonas macleodii, with a focus on …

COMMUNITY STRUCTURE AND FUNCTIONAL DIVERSITY OF IMPERILED GREAT PLAINS FISHES: IMPLICATIONS FOR CONSERVATION OF TWO ENDANGERED SHINERS (SHARPNOSE SHINER NOTROPIS OXYRHYNCHUS AND SMALLEYE SHINER NOTROPIS BUCCULA) IN THE UPPER BRAZOS RIVER, TEXAS
… regime and river fragmentation. Uncovering the abiotic and biotic drivers across spatial and temporal scales influencing fish assemblages across the Great Plains is required to inform effective management strategies. Here, I investigated ecological drivers influencing fish assemblages containing …

Ecosystem impacts of variable recruitment in Antarctic krill investigated with long-term monitoring and archived ADCP backscatter data
… Profiler (ADCP) to investigate biotic and abiotic drivers of summer krill distribution along the mid-to-coastal shelf region of the western Antarctic Peninsula.In Chapter 1, my coauthors and I examine the impact of cyclical krill recruitment on Adélie penguins. Between 1992 and 2018, the …
