Adaptive dynamics is a mathematical theory that links
population dynamics to long-term evolution driven by
mutation and natural selection. It provides methods of
model formulation, methods of model analysis as well
as mathematical theorems that relate phenomena on
an evolutionary time scale to processes and structures
defined in ecological and population dynamical terms.

ECOLOGICAL TIME SCALE
The ecological time scale concerns the question which mutant phenotypes that are not yet present in a population of given resident phenotypes could invade if they were produced by a mutation, and what would be the outcome of such an invasion in terms of which phenotypes will remain in the population and which will be eliminated. These questions concern dynamics in a space of population densities of different phenotypes. In the course we focus on the population dynamics given by (systems of) ordinary differential equations.

EVOLUTIONARY TIME SCALE
The evolutionary time scale is about the long-term consequences of many successive ecological invasion-elimination events in terms of changes in the phenotypic composition of the population. The evolutionary time scale thus concerns dynamics in the space of all possible phenotypes. This dynamics is essentially non-deterministic (e.g., due to the random nature of the effect of a mutation on the phenotype) and is studied using difference inclusions, and in limiting case of infinitesimally small mutation steps, the Focker-Planck equation or the transport equation.

EXAMPLES
Examples are largely taken from recent publications in the scientific literature.

PERSPECTIVE
Adaptive dynamics is a new but rapidly developing theory that poses various interesting and mathematically challenging problems. From an applications point of view, a great strength of adaptive dynamics is its capability to model evolution in systems with complicated ecological interactions. Adaptive dynamics is being applied by a growing number of researchers both within mathematics and biology to a wide variety of concrete ecological-evolutionary problems.

REFERENCES
Adaptive dynamics is new, and there does not exist a comprehensive textbook on adaptive dynamics. For an extensive list of references to both theory and applications of adaptive dynamics in the scientific literature, see the website http://www.mv.helsinki.fi/home/kisdi/ad.htm

LECTURE NOTES
Lecture will be produced on the go as the course advances. Older lecture notes are available here https://wiki.helsinki.fi/display/mathstatKurssit/Adaptive+dynamics,+fall...

EXAMINATION
There will be no exam -- instead there will be project assignments. In the second half of the course, the project assignments take the place of the homework exercises. The lecturer or the assistant will be available for advise during the normal time and place of the exercise classes. A written report and a 15 minute in-class presentation of the report take the place of the exam, i.e., the grade is based on the report and the presentation. The presentations take place during the last week of the course.

PREREQUISITES
Basic knowledge of differential equations, probability theory and some skills in programming (preferably Mathematica or Maple).

I have selected a collection of papers for the projects, but because of copyright issues I cannot just dump them in the section MATERIALS below -- still have to figure out how we do that ...

For the exercise class on Tuesday 23 January from 14:15-16:00 room B121, we will look at the example model in the paper "Evolutionary singular strategies and the adaptive growth and branching of the evolutionary tree" by Geritz et al. in Evolutionary Ecology 1998, Vol. 12, pp. 35-57.

I have moved the exercises classes from Mondays 12-14 to Tuesdays 14-16.
I hope this is consistent with the schedules of at east most of you.

N.B., the change required the "old" classes to be cancelled before the "new" classes could be installed. If you find that your enrollment has been cancelled in this process, just enroll again.)
