  1. 1. COMPARING THE COMPOSITION OF SAPROXYLIC BEETLE FAUNA ON OLD HOLLOW OAKS BETWEEN TWO TIME PERIODS

    University essay from Linköpings universitet/Biologi

    Author : Chipango Kamboyi; [2019]
    Keywords : Saproxylic beetles; Guilds; Species composition; Canopy Cover; Forest Regrowth; Trunk Circumference; Cavity size. Species turnover;

    Abstract : 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.

  3. 2. Medium-term population development and responses to habitat conditions of a beetle, Osmoderma eremita, inhabiting hollow trees

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Olle Tranberg; [2016]
    Keywords : Osmoderma eremita; European hermit beetle; metapopulation; colonization and extinction; habitat; saproxylic species; tree hollows; Pedunculate oak; Quercus robur;

    Abstract : 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). READ MORE

  4. 3. Boxing for biodiversity: a long-term follow up of an artificial dead wood environment

    University essay from Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakulteten

    Author : Staffan Carlsson; [2015]
    Keywords : Artificial habitats; saproxylic beetles; wood mould boxes; hollow trees; succession;

    Abstract : Today many saproxylic species are threatened because of habitat decline in Europe. Hollow trees represent a great part of the habitats that saproxylic species use. Since hollows takes a long time to develop, management actions are needed to prevent the extinction of saproxylic species. READ MORE

  5. 4. Pheromone-based monitoring of Elater ferrugineus as an indicator for species-rich hollow oak stands

    University essay from SLU/Plant Breeding and Biotechnology (until 121231)

    Author : Klas Andersson; [2012]
    Keywords : Elater ferrugineus; Osmoderma eremita ; saproxylic; indicator ; Quercus sp. ; pheromones; conservation;

    Abstract : The rare beetle Elater ferrugineus was sampled at 47 sites in the county of Östergötland, Sweden by means of pheromone-baited traps to assess its value as an indicator species for hollow oak stands rich in rare saproxylic beetle species. In addition Osmoderma eremita was sampled with the same method. READ MORE

  6. 5. Comparison of saproxylic beetle assemblages on four different broad-leaved tree species in south-eastern Sweden

    University essay from Institutionen för fysik, kemi och biologi

    Author : Helena Johansson; [2011]
    Keywords : Conservation; coleoptera; beetles; saproxylic; broad-leaved trees; hollow; preferences;

    Abstract : Old hollow trees have declined in Europe and many saproxylic (wood-dwelling) beetles dependent on them are threatened. Several studies have been done on old hollow oaks and they have been shown to harbour a species-rich saproxylic beetle fauna. However, other broad-leaved trees might also be important to consider as supporting habitats. READ MORE
