Adaptive dynamics is a theoretical framework to study frequency- and density-dependent
evolution with a high degree of ecological realism. This framework integrates and extends
concepts and techniques from evolutionary game theory, with special emphasis on dynamical
phenomena such as the origin and divergence of new lineages by evolutionary branching.
A great strength of adaptive dynamics is its capability to incorporate ecological complexity
and to model long-term evolution as driven by ecological interactions. The theory of the ESS
has been enormously successful in analysing evolution in complex ecological and behavioural
interactions. Adaptive dynamics is an extension of the ESS-theory that preserves its wide
applicability to diverse ecological systems. It is being applied by a growing number of
researchers to a wide variety of concrete ecological-evolutionary problems.
The lectures will focus on the fundamental theory of adaptive dynamics, but also look
more briefly at the links between adaptive dynamics and other modeling frameworks
and at the current research challenges within the field. The lectures given in the
first week will enable the participants to solve a practical student project, which constitutes
the main bulk of the course. This includes the concepts and techniques of adaptive dynamics,
but also some widely applicable numerical methods and general principles of model analysis.
The lectures of the last week will round off the course by discussing current developments,
open challenges, and place the material in wider context for example by linking adaptive dynamics
to speciation theory.

discussion and evaluation of projects
Figures used during the lectures can be downloaded as pdf files:
As the goal of this course is to give working knowledge in adaptive dynamics, the projects constitute
the main part of the course. You can choose a project from the list below, subject to the constraint
that each participant must have a different project. The projects are developed
individually. The results of the project must be written up in a report of 5-10 pages
(including figures), which is due by 4 February (the deadline is strict). Then each participant
will read the report of one other project and prepare a brief (1/2 page) summary of it.
Between 13 and 15 February, each project will be discussed briefly with the author and with
the reviewing participant, and graded on a pass-fail scale. The course has no
formal exam; the grade is determined by the completion and quality of the project.
Working on the projects
The projects assume some familiarity with modelling and an attitude of research: the task is to understand
the evolutionary dynamics in a given ecological system rather than to answer some pre-defined questions as in an
exam (some hints will be given to help getting started). Weekly discussions will monitor progress, give an
opportunity to discuss difficulties, and compare methods and results with others. The projects, while simple
relative to the level of complexity that can be handled in adaptive dynamics, constitute valid research problems
of the past decade.
Most projects are based on published papers. Please do not try to trace down the paper while working on the
project. The intention is that you do independent work. Also, the published paper may differ from the project
in some aspects, and the projects often go beyond the published material. The references will be distributed among the course participants
after the completion of the projects (anyone else interested in these projects please contact the lecturer
for references). In every case you use material from the projects later on, please consult the references carefully and
cite the original papers appropriately.
When writing the report, assume that the reader knows the course material but no more. Introduce the ecological
problem at hand. Link the analysis to the background given in the course. In the Discussion part, summarise
the most important findings and mention if you see possible directions of further research or ways to improve
the ecological model given in the project.
Please submit the report in one pdf file. It may be tempting to submit a Mathematica or similar interactive
notebook you developed where the user can explore various phenomena in the model. Please do not do so.
Besides possible software incompatibility problems, it is your job to decide which results are worth
mentioning in the report and to make sure the analysis is complete. Just like when writing a research paper,
a text file with figures must be sufficient.
Participants must have access to a computer and a software package suitable for mathematical modelling
which they are familiar with. Typical tasks during numerical analyses of adaptive dynamic models include the following:
iterating population dynamics in discrete time; solving differential equations (using the simplest numerical algorithm);
finding roots of functions numerically; numerical differentiation; plotting functions (including very complicated functions obtained numerically);
contourplots of functions of two variables. All of these must be done easily with the software, since these are commonly applied
to complicated equations/functions and repeated many times automatically.
The lectures will explain the basics of the necessary numerical algorithms. Ordinary programming languages
such as C, Pascal, etc. are suitable for the implementation of these algorithms. Mathematical packages such as
Mathematica, Maple, Matlab can do the same and also provide shortcuts in form of pre-programmed algorithms.
Participants are free to choose the software they use, but we may be unable to provide technical assistance with software
problems if the chosen software is not familiar to us.
