  1. 1. Migration routes, stopover sites and home range sizes of Taiga Bean Geese (Anser fabalis fabalis) breeding in northern Sweden and central Norway tracked by GPS tags

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Jorina Boer; [2019]
    Keywords : Taiga Bean Goose; Anser fabalis fabalis; migration; GPS; stopovers; home range;

    Abstract : The Taiga Bean Goose (Anser fabalis fabalis) has shown a recent decrease in population size. For geese breeding in central Scandinavia, the delineation between different subpopu-lations is not entirely clear and more detailed knowledge regarding migratory routes is still lacking. READ MORE

  2. 2. The use of spatial and temporal analysis in the maintenance of road mortality mitigation measures for wildlife in Ireland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Aoife Moroney; [2018]
    Keywords : roadkill; wildlife crossing; hotspot analysis; ripley s k; KDE; SANET;

    Abstract : Urbanisation and a growing global population have caused our road networks to expand rapidly in the past decades. The consequences of transport infrastructure for wildlife include traffic mortality, habitat loss and habitat degradation and the negative impact of a road extends far beyond the road itself.

    Abstract : In recent decades, the rate of extinction of species is increasing due to human use and refinement of nature. This has resulted in a large amount of research throughout the world. Forestry today is mostly based on clear cuts, and many natural forests have been cut down and replaced with monocultured forests. READ MORE

  4. 4. Spatial Modeling of Wildlife Crossing:GIS-based Approach for Identifying High-priority Locations of Defragmentation across Transport Corridors

    University essay from KTH/Geoinformatik

    Author : Josefine Jonsson; [2017]
    Keywords : wildlife crossing; GIS; Circuit Theory; habitat; defragmentation;

    Abstract : In this report, connectivity modeling has been performed using land cover data to find habitat pinch-points for deer along the study area Norrortsleden in Stockholm. Norrortsleden was chosen because there are a high number of deer accidents in the area, and is a priority area for action according to a barrier analysis for deer made by the Swedish Transport Administration.

  5. 5. Grey-sided vole and bank vole abundance in old-growth forest patches of different size and connectivity

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Niklas Paulsson; [2011]
    Keywords : grey-sided vole; bank vole; habitat patch size; old-growth forest; connectivity; population decline; environmental monitoring; boreal forest;

    Abstract : Vole populations in northern Scandinavia vary in cycles with peaks every third or fourth year as described by the National Environmental Monitoring Programme of small mammals (NEMP). Some vole species have declined in population numbers since the NEMP started in 1971, especially the grey-sided vole (Myodes rufocanus) which is nearly extinct in the forested region. READ MORE
