Unlike common ordination procedures used to reduce the number of dimensions, n-dimensional hypervolumes fully consider each individual factor (dimension). Thus, this concept has the potential to handle multivariate and complex data without oversimplifying the patterns and camouflaging important explanatory variables. In the symposium, we will introduce and compare different statistical approaches, give examples of their applicability and discuss open questions and the potential of n-dimensional hypervolumes in ecology and beyond.
