Complex adaptive systems at the interface of ecology and evolution: an integrative overview Ulf Dieckmann (Evolution and Ecology Program, International Institute for Applied Systems Analysis, A-2361 Laxenburg, Austria) Understanding complex adaptive systems requires a marriage of population dynamics with adaptive dynamics. Adaptation in living systems cannot be understood without accounting for the rich embedding of populations. Conversely, predicting the future of populations, especially when exposed to strong anthropogenic impacts, requires accounting for the prospect of rapid adaptation. This presentation provides an integrative overview of modeling approaches linking ecological and evolutionary dynamics, ranging from evolutionary games, adaptive dynamics, and evolutionary reaction-diffusion systems to agent-based models tackling the complexities arising from the genetic, spatial, and demographic structure of real-world systems.
