    Sammanfattning : In Sweden today, deciduous woodlands are often restricted to small isolated remnants of what it once was. Managing practices have changed concerning both cattle grazing and logging. Thus, dispersal, habitat requirements and their importance for forest species distributions become a relevant issue.

  3. 2. Biological diversity values in semi-natural grasslands : indicators, landscape context and restoration

    Författare :Mathias Öster; Ove Eriksson; Martin Zobel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; connectivity; Hygrocybe; indicators; landscape history; plants; pollen limitation; species-area effects; surrogate species; Biology; Biologi;

    Sammanfattning : Semi-natural grasslands, which are a declining and fragmented habitat in Europe, contain a high biodiversity, and are therefore of interest to conservation. This thesis examines how plant diversity is influenced by the landscape context, and how plant and fungal diversity can be targeted by practical conservation using indicator species and congruence between species groups.
