The colonization of a new habitat is a fundamental process in metapopulation biology 1, but it is difficult to study. The emigration of colonists from established populations might be induced by resource competition owing to high local population density 2, 3. Migration distances are also important because they determine the frequency and scale of recolonization and hence the spatial scale of the metapopulation 4. Traditionally, these factors have been investigated with demographic approaches that are labour-intensive …
