14 This course will explore how to model the dynamics and evolution of populations with spatial movement, spatial constraints and spatial interactions between organisms. We start with a brief introduction to mathematical ecology. In spatial ecology, we study diffusion, travelling waves, pattern formation and Turing instability, stochastic patch occupancy models, structured metapopulation models, probabilistic cellular automata and coupled map lattices. We also discuss topical issues of evolutionary biology where spatial structure plays a crucial role, e.g. the evolution of mobility (dispersal), specialisation to different environments, and why space matters for the evolution of altruistic behaviour.
15
16 This is a course in applied mathematics. Instead of choosing the problem to suit a method, we emphasize the use of versatile techniques. We introduce/review methods for ordinary differential equations and difference equations, partial differential equations, Fourier analysis, stochastic processes, pair approximation methods, game theory and adaptive dynamics. When necessary, we turn to numerical analysis.

43 The exam lasts 2,5 hours. You can use notes, books etc in the exam. Computers are not needed, but may be used with the internet switched off (download necessary files in advance).
44
45 The final grade is 80% exam + 20 % computational projects. Course activity (exercise classes and quick tests) decides marginal grades.

81 This [[pdf>>attach:computer_projects.pdf]] contains the computer projects you can choose from; everyone must have two projects from different sections. Email your choice to me. You can choose the same project as someone else in the course, but then your second choice must be different from that student.
