Abstract:

      In this course, I present various approaches to model spatial population dynamics in ecology. Mathematical models of population dynamics describe how population size in focus changes with time. These are usually given as ordinary differential equations in continuous time or difference equations in discrete time. These "non-spatial" models can be extended to be "spatial" where spatial distributions of populations are explicitly considered, e.g., lattice models in discrete space or reaction diffusion models in continuous space. Apart from these analytical models, or equation-based models, spatial population dynamics can be algorithmically described as point pattern dynamics where a point pattern changes with time by birth and death (and movement) of points as individuals in continuous space. I present a general way to implement point pattern dynamics as a simulation model and discuss how analytical models and algorithmic models are related to each other.
