Mathematical models in evolutionary dynamics
We consider two mathematical models in evolutionary dynamics. The first model is an extension of an evolutionary game theory model proposed by Martin Nowak. We consider both a mean field deterministic approach and a weak noise stochastic approach, but the focus is on latter which is an uncommon …

Critical phenomena in evolutionary dynamics
This thesis consists of five essays on evolutionary dynamics. In Chapters 1 and 2, we study the evolution of trust from the perspective of game theory. In the trust game, two players have a chance to win a sum of money. The "investor" begins with one monetary unit. She gives a fraction of that unit …

Evolutionary dynamics of speciation and extinction
… between the fields of physics, mathematics, and evolutionary biology. Importantly, as we move through the Anthropocene Epoch, where human-driven climate change threatens biodiversity, understanding how an evolving population responds to extinction stress could be key to saving endangered …

Evolutionary dynamics of digitized organizational routines
… the effects of increased digitization on the evolutionary dynamics of organizational routines. Do routines become more flexible, or more rigid, as the mix of digital technologies and human actors changes? What are the mechanisms that govern the evolution of routines? The dissertation theorizes …

Evolutionary dynamics of the hominin pelvis
… of evolution. As such, the particulars of the evolutionary dynamics that underlie morphological change are generally unknown. This study attempts to fill that void by applying evolutionary quantitative genetic theory and methods to the study of hominin pelvic evolution. There are three sets of …

Evolutionary dynamics of the Yersinia enterocolitica complex
… as well as environmental species. The evolutionary history of Y. pestis has been well documented, but information on the evolutionary relationship between the other Yersiniae is less characterized. Y. enterocolitica is a diverse species classed into six different biotypes (BT), but only …

Evolutionary dynamics of the human gut microbiome
… members in the ecosystem. Understanding the evolutionary dynamics of microbial species in the gut microbiome requires sequencing information that differentiates strains and even single cells. In this thesis, I present efforts that investigate the evolution of bacterial strains in their …

The eco-evolutionary dynamics of microbial populations
Microbes have adapted to life in complex microbial communities in a large variety of ways, and they are continually evolving to better compete in their changing environments. But identifying the conditions that a particular microbe thrives under, and how they have become adapted to those condition …

Evolutionary Dynamics of the Alpha-actinin Gene Family
The alpha-actinin gene family is a member of the spectrin superfamily of proteins. Other members of this superfamily include the a- and ~-spectrins, ~heavy spectrin and dystrophin. Each member of this superfamily has a unique actin cross-linking distance consequent to the specific number of …

Evolutionary Dynamics of Social Behaviours on Multilayer Networks
… hence the work is mainly focused on studying the evolutionary dynamics of cooperation and social behaviours on a multilayer social network. Following a Bio-inspired approach, the social network analysis methodologies, and exploiting the mathematical framework of Evolutionary Game Theory (EGT), the …

Population and evolutionary dynamics during microbial range expansions
Spatial expansions occur across multiple scales, from the expanding range of a species to the growth of tumors and microbial biofilms. In ecology, range expansions are becoming more frequent due to environmental changes and rare long distance dispersal, often facilitated by anthropogenic …

Exploring multispecies evolutionary dynamics using model microbial ecosystems
Experiments to date probing adaptive evolution have predominantly focused on studying a single species or a pair of species in isolation. In nature, on the other hand, species evolve within complex communities, interacting and competing with many other species. We developed experimental microbial …

Evolutionary dynamics of avian and non-avian limb morphology
… structure, and particularly how it changes over evolutionary time, will reveal how genetic variation translates into phenotypic variation, the sources of and limits to variation, and ultimately a mechanistic understanding of phenotypic evolution. Traits may covary due to several possible …

THE ROLE OF COMPLEX EVOLUTIONARY DYNAMICS IN MOLECULAR SEQUENCE ANALYSIS
… events (MH) on the statistical inference of evolutionary rate parameters. In evolutionary terms, MH events represent rare phenomena which may have strong effects on protein-coding genes. Evidence for MH events directly impact the patterns and processes of protein-coding gene evolution across …

Defining the Epigenetic Evolutionary Dynamics that Precede Acute Myeloid Leukaemia
… as the tumour develops, and how methylation dynamics are shaped by the acquisition of somatic driver mutations. Acute Myeloid Leukaemia (AML) is a good model system with which to address these questions. As well as the ease of sampling blood, mutations in epigenetic modifiers are some of the …

The eco-evolutionary dynamics of extrachromosomal elements in environmental vibrio

Computational Insights into Evolutionary Dynamics of Human and Primate Genes
The evolutionary history of genes across different species is a subject of research interest. For human genes, there is a particular focus on investigating the possible origins of genes. However, there has been limited research on the development process from an evolutionary perspective. …
