    University essay from SLU/Dept. of Ecology

    Author : Andreas Öhlund; [2022]
    Keywords : bäver; Artportalen; medborgarforskning; inventering; Uppland; Uppsala;

    Abstract : Artportalen är Sveriges centrum för medborgarforskning för arter och har bidragit till miljontals inrapporteringar. Medborgarforskningen kan vara ett viktigt verktyg för framtida forskning, trots osystematiskt insamlade data. I Sverige för 100 år sedan var bävern (Castor fiber) utdöd. READ MORE

  5. 4. The relative importance of beavers (Castor fiber) and browsers on the recruitment of broad-leaved trees in riparian areas

    Author : Matilda Karlsson; [2019]
    Keywords : beaver; Castor fiber; ungulates; herbivory; broad-leaved; riparian; conservation management;

    Abstract : Managed forest landscapes in Sweden are dominated by boreal coniferous forest and are deficient in broad-leaved trees.

  6. 5. Abundance and diversity of small mammals in Swedish beaver systems

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Felicitas Glabischnig; [2015]
    Keywords : small mammals; beaver; Castor fiber; habitat heterogeneity; ecosystem engineer; biodiversity; bank vole; Myodes glareolus; wetlands;

    Abstract : Through their ecosystem engineering activities, beavers (Castor fiber ) create ponds and riparian zones littered with deadwood, providing hetero- geneous micro-habitats for a variety of small mammal species. In this study small mammals were snap-trapped in nine beaver systems and four reference wetland systems that were not created by beavers in southern and central Sweden to compare abundance and diversity of voles, shrews and mice.
