Theoretical studies in ecology have shown that the outcome of ecological interactions at the population, community and system level may change dramatically when the spatial context of these interactions is explicitly taken into account. Compared to the predicted outcome in a continuously stirred homogeneous environment, essential features such as stability of interactions, resilience of the system, diversity of communities and persistence of populations are fundamentally affected by spatial relationships (i.e. depend on distances, spatial configuration of the habitat, mobility, transport etc.). Likewise, theoretical explorations have demonstrated that interactions between organisms and their physical habitat can lead to pattern formation and structuring of the habitat, and that the spatial context profoundly affects the dynamics of these interactions. All these theoretical explorations provide a number of qualitative predictions. It remains a scientific challenge to expand them, translate them into testable hypotheses and to validate them in the field or laboratory.
Empirical studies of real populations, and especially large-scale long-term ecological data sets provide a wealth of spatially structured information. It is a major challenge to summarize and interpret these data within a theoretical context. This entails formulating hypotheses about underlying processes and the use of experimental approaches, both in the field and the laboratory. Due to logistic constraints, experiments are necessarily executed at small spatial scale. However, they can be linked to observed larger-scale patterns through the use of modelling.
