Learning outcomes

The aim of the course is to give students with a background in biology basic skills in building and analysing mathematical models of biological systems. On completion of the course, the student should be able to:

  • outline the principles behind modelling - why mathematical models?
  • perform the modelling cycle - (i) translate a biological question into a mathematical model, (ii) analyse the model and (iii) interpret the results
  • choose the appropriate modelling framework for different biological questions - quantitative vs qualitative models - deterministic vs stochastic models
  • analyse models formulated in terms of differential and difference equations: equilibria and their stability, basic numerical methods
  • understand, analyse and apply classic models in ecology and evolution: density-dependent population growth, models of species interactions and structured population models, evolutionary models of allele frequency change and invasion analysis
  • critically interpret scientific papers that are based on mathematical models

Content

  • The modelling cycle: (i) translating a biological question into a mathematical model, (ii) mathematical analysis of the model, and (iii) interpreting the mathematical results in terms of biology
  • Standard models in ecology: models for the dynamics of unstructured and structured populations, models of competition and predation
  • Standard models in evolution: one- and two-locus models, quantitative genetics and the breeders' equation, invasion analysis, the stochastic Wright-Fisher and Moran models for allele frequency change
  • Stability analysis of linear and non-linear models in one and two variables, phase-plane analysis, elementary vector and matrix algebra, eigenvalues and eigenvectors, elementary probability theory.

Instruction

Lectures, home-assignments and exercise classes.

Assessment

Home-assignments and active participation during the tutorials.

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
