Deepened knowledge on response of biota and ecological processes following fire is essential for a future with warmer climate and more disturbances. In 2014 the first mega-fire (13,100 ha) for at least a century in Scandinavia hit south-central Swede

Fire-favoured insects are difficult to sample except opportunistically after forest fires. Here, we tested if smoke from a small fire could be an efficient way to sample such insects. Insects were sampled over ca. 10 h hours, by hand-picking and nett

Despite increasing awareness of the theoretical importance of habitat dynamics on metapopulations, only a few empirical studies have been conducted. We aimed to increase our understanding of how patch size, dynamics and connectivity affect colonizati

Species adapted to early-successional forest habitats are in managed landscapes largely confined to clearcuts. To improve habitat quality on clearcuts, green tree and dead wood retention is widely applied in forestry; however, its effects on rare ear

La quantite de bois mort dans les forets a diminue a cause des pratiques forestieres modernes et plusieurs especes associees a cet habitat se trouvent actuellement menacees. En Suede au cours de la derniere decennie, les troncs tombes naturellement s

Several boreal wood-living insect species breed exclusively in recently burned forest. However, the reason for this dependence on fire is largely unknown. Here wood-living insects and other arthropods were sampled from burned and unburned logs of bir

We studied how variations in fire severity and the degree of cutting before burning affected soil invertebrates in a Pinus sylvestris forest in central Sweden. A varied depth of burn in the mor layer was obtained by exclusion of rain and addition of
