The eco-evolutionary dynamics of microbial populations
… microbe thrives under, and how they have become adapted to those condition can be exceedingly difficult. For instance, Clostridium difficile became widely known for being the world's leading cause of hospital associated diarrhea, but people can also have C. difficile in their gut without …

The eco-evolutionary dynamics of extrachromosomal elements in environmental vibrio
… and other extrachromosomal elements (ECEs) are recognized as key factors mediating horizontal gene transfer; however, their diversity and dynamics among ecologically structured host populations in the wild remains poorly understood. Here we take a population-genomic approach to determine carriage …

The role of landscape structure in determining eco-evolutionary dynamics during environmental change
… produce a variety of responses in populations' ecological and evolutionary dynamics. At opposing limits of populations' ranges, the responses are expected to differ. Some lag in response may be expected due to the rapidity of climate change, with the strength and type of lags varying across …

Diversity, variability and persistence elements for a non-equilibrium theory of eco-evolutionary dynamics
Natural ecosystems persist in variable environments by virtue of a suite of traits that span from the individual to the community, and from the ecological to the evolutionary scenarios. How these internal characteristics operate to allow living beings to cope with the uncertainty present in their …

The effect of viral plasticity on the coexistence and eco-evolutionary dynamics of host-phage systems
… organisms. In marine environments, viruses are recognized as an important factor altering phytoplankton and bacterioplankton growth and dynamics. However, it is still unclear the exact role that viruses play in the regulation of their host populations. As a consequence, generalizing …

Drivers of eco-evolutionary dynamics in model systems - the role of harvest mortality and intraspecific competition
… how such adaptation can feedback to population dynamics - I also address the outcomes of real world pressures on populations and in chapter IV offer a potential solution to one of those pressures, specifically fishing. This thesis therefore represents an exciting addition, not only to the field …

Understanding the eco-evolutionary dynamics underpinning changes in air-liquid interface biofilms in radiating populations and multi-species communities
Static liquid microcosms have been used to study evolutionary and ecological dynamics of bacterial populations, where metabolic activity produces a heterogenous environment with a low-O2 region in the liquid column, and a high-O2 region directly below the air-liquid (A-L) interface. This system has …

The evolutionary ecology of methylation-dependent bacterial defense systems
… considerable gaps in our understanding of the evolutionary ecology of MGEs and host defenses. Given the role of MGEs in spreading drug resistance alleles, the current focus on developing bacteriophages as alternative antimicrobials, and the ability for host defenses to interfere with both, it …

Spatial-temporal patterns in evolutionary ecology and fluid turbulence
"This thesis explores the turbulence of ecosystems, and the ecology of turbulence. Ecosystems and turbulent fluids are both highly non-equilibrium and exhibit spatio-temporal complexity during the course of their evolution. It might seem that they are too complicated to extract universal …

Evolution at the edge: how hibernation, heat waves, and hybridization impact a range expansion
Evolutionary processes shape the diversity of life on earth. Over millennia, species diverge from one another, radiating out into the tree of life. The same processes of evolution are also acting in much shorter periods of time, selecting for traits, mixing genes across populations, and generating …
