Evolutionary dynamics on multi-dimensional fitness landscapes

Evolution is the common theme linking everything in biology from individual alleles to languages. Darwin believed that those who were mathematically inclined had a different insight and he regretted not having it. He probably would feel gratified knowing that now evolution has gained a solid mathematical...

Evolutionary Game Dynamics Driven By Mutations Under Frequency Dependent...

Evolutionary game theory and theoretical population genetics are two different fields sharing many common properties. In both fields, theoretical models are built to explore evolutionary dynamics; various evolutionary forces, such as selection, mutation, and random genetic drift, are involved in the...

Adaptation of bacteria to temporally changing antibiotic environments

The variability of the environment is a challenge for the flexibility of organisms. Temporal variation generates interesting optimization conflicts for evolution, which were investigated in this doctoral thesis for the example of the bacterium Pseudomonas aeruginosa and the sequential treatment with...
Dissertation

Applying evolutionary game theory in modeling life history evolution and...

One major innovation in this thesis project is to build a system that takes into account both aspects and connects the two theoretical frameworks. This is realised by defining age/life-stage dependent strategies. Besides an analytical and numerical study of abstract mathematical models, this thesis also...

Selection intensity and the time to fixation in evolutionary systems

Processes of Darwinian evolution are dynamic, nonlinear, and underly fluctuations. A way to analyze systems of Darwinian evolution is by using methods well established in statistical physics. The main mechanisms that are responsible for evolutionary changes are reproduction, mutation, and selection....
