Evolutionary Trade-offs Between Antimicrobial Resistance and Virulence in Pseudomonas aeruginosa
… (AMR) threatens antibiotic efficacy, yet its evolutionary consequences for pathogen virulence and growth remain poorly resolved. This thesis addresses this gap using Pseudomonas aeruginosa, a multidrug-resistant pathogen capable of both acute toxin-mediated and chronic colonization-based …

Evolutionary trade-offs and adaptive phenotypic plasticity under multidimensional selective pressure
… at all levels of organization are the product of evolutionary change. However, predicting how phenotypes respond to selective pressure via a quantitative theory of evolution remains challenging due to a number of factors complicating the genotype to phenotype map. Genetic architecture presents an …

Evolutionary Ecology of the First Animal Ecosystems
… establish the nature of universal ecological and evolutionary rules. Within this thesis I exploit under-accounted-for features of Ediacaran palaeocommunities preserved in Newfoundland to constrain and account for biases in palaeocommunity datasets, and to directly test associations between …

Potential Downstream Immunological Effects of Evolved Disease Tolerance in House Finches
… variation in the degree of population co-evolutionary history with the pathogen. Prior work found that populations of house finches with longer histories of MG endemism have evolved tolerance and resistance to MG, and this evolution is associated with several immunological differences …

BEHAVIORAL ECOLOGY OF ORYZOMYS PALUSTRIS (MARSH RICE RAT) IN COASTAL TEXAS: IMPLICATIONS FOR THE LIFE-HISTORY STRATEGY OF BAYOU VIRUS (BAYV)
… research lies in its illumination of potential evolutionary trade-offs in BAYV host selection, infection, and fitness, in which all are strongly influenced by habitat characteristics. With a clearer understanding of the life history strategy of BAYV and the behavioral ecology of Texas O. …
