The main hypothesis that isopods from the cave phenotype would be less dispersive than isopods from the surface phenotype could not be supported by the results. Neither could support for similar dispersal be obtained or higher dispersal for the cave phenotype. However, it is reasonable to assume either similarity or difference between the phenotypes occur. The inconclusive results might derive from large variation in dispersal data on both individual and population level, but also on divergent adaptations which yield similar expression of dispersal. Further study with experimental design which is more adapted to the discontinuous and variable movement of the isopods may bring clarity to the question. That body size had positive effects on dispersal in the common garden analysis highlights the potential of the concept behind this study.
