  2. 6. Community Assembly and Spatial Ecology of Saproxylic Coleoptera

    Author : Jonas Victorsson; Mats Björklund; Stefan Ås; Anne Magurran; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terrestrial ecology; Terrestisk ekologi; Animal Ecology; zooekologi;

    Abstract : Community assembly is the process deciding inclusion/exclusion of species in a developing community. Spatial ecology integrates spatial habitat factors with local biotic interactions within a given patch. I used standardized tree bolts (0.35-1 m long) to sample saproxylic (wood living) beetles in natural and managed forest types. READ MORE

  4. 7. Forest restoration guided by an umbrella species : will measures to protect the white-backed woodpecker benefit saproxylic beetles?

    Author : David Bell; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Management shortcuts in conservation biology, like the umbrella species concept, have been debated worldwide. Umbrella species have been used to identify and delineate protective areas, but habitat requirements of umbrella species can also provide tangible targets in ecological restoration. READ MORE

  5. 8. Bark beetles facilitate the establishment of wood decay fungi

    Author : Ylva Strid; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Forests in the northern hemisphere are largely dominated by conifers and provide a key habitat for a multitude of species. Wood decay fungi, i.e. basidiomycetes, are important for nutrient cycling. READ MORE

  6. 9. Oak as retention tree in commercial spruce forests : effects on species diversity of Saproxylic beetles and wood production

    Author : Maria Susanna Koch Widerberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Retaining trees valuable for biodiversity is a common conservation measure. There are indications that such trees have important benefits for the diversity of many species groups. However, retaining trees may also have negative effects on timber production. READ MORE

  7. 10. Conservation of saproxylic species : an evaluation of set-asides and substrates in boreal forests

    Author : Line Djupström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Forest management has altered the prerequisite of many species in forest landscapes. The new, more conservation-oriented forest management includes a range of different strategies that aim to prevent losses of biodiversity. READ MORE
