21. COMPARING THE COMPOSITION OF SAPROXYLIC BEETLE FAUNA ON OLD HOLLOW OAKS BETWEEN TWO TIME PERIODS
Master-uppsats, Linköpings universitet/BiologiSammanfattning : Oak habitats are rich in saproxylic species, but the habitat is declining with loss of diversity due to encroachment which decrease the vitality of oaks. The present explorative study compared results from a study conducted in 1994, with present species communities to observe if there has been change in species composition and what factors that can explain species diversity and composition.

25. Medium-term population development and responses to habitat conditions of a beetle, Osmoderma eremita, inhabiting hollow trees
Uppsats för yrkesexamina på avancerad nivå, SLU/Southern Swedish Forest Research CentreSammanfattning : Old oaks play an important role in the southern Swedish landscape by maintaining available habitats for many saproxylic species, several of which today are on the international Red List of threatened species. Old oaks can develop important habitats, such as hollows with wood mould, which is the habitat for the European hermit beetle (Osmoderma eremita). LÄS MER
