AbstractIn nature conservation it is important to understand under which circumstances populations can survive by compensating local extinctions with colonisations. Many saproxylic (= wood-dwelling) insect species have declining populations and are regarded as threatened due to low habitat availability in managed forests. Several methods have been used to better understand the dispersal biology and colonisation ability of saproxylic insects with declining populations. In this paper, I summarize and compare the results of such studies. When the same species have been studied using several methods, the results are consistent, but different aspects of dispersal biology are revealed with different methods. Capture-recapture and telemetry are direct methods that can be used to quantify dispersal rate and range in the field. Studies of genetic structure and occupancy patterns are complementary, as they reveal the consequences of dispersals that have taken place over a larger spatial and temporal scale than is possible to study with direct methods. Because colonisation, rather than dispersal, is most important for population persistence, colonisation experiments provide useful information. To obtain information relevant for conservation work dispersal studies should be conducted on model species that are representative of threatened species. Colonisation ability probability differs between common and rare species, and therefore it is important to also study dispersal of rare species, even if it is more difficult.
