Water-filled tree holes represent isolated and ephemeral aquatic microenvironments in forests worldwide. They are embedded within terrestrial ecosystems, providing a niche for diverse aquatic insect assemblages. These systems are convenient models as they are small, can be treated as discrete units, are very tractable and can be mimicked with artificial analogues. However, the communities inhabiting them are still largely unknown. In this context, we studied artificial tree-hole macroinvertebrate communities in and around two Austrian national parks. Forest areas that serve as steppingstones outside the national parks were compared with areas inside the national parks.
