  1. 1. Faunabroar: Är det framtiden för minskade viltolyckor?

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Lisa Huss; [2023]
    Nyckelord :viltolycka; faunapassager; vilt; dataanalys;

    Sammanfattning : Wildlife vehicle collisions (WVC) are a problem in the world that is costly and can create suffering for the affected. Every year about 65 000 WVC are reported in Sweden only. Fauna passages are built to try to reduce WVC and the fragmentation that road networks make. LÄS MER

  3. 2. Wildlife-vehicle collisions : An evaluation of the mitigation effect by ecoducts and fauna bridges in Sweden

    Magister-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Anna Rietz; [2023]
    Nyckelord :Space time pattern mining; Space time cube; Emerging hot spot analysis; Overlay analysis; Bivariate choropleth map; ArcGIS Pro; Wildlife-vehicle collision WVC ; Annual daily traffic;

    Sammanfattning : The occurrence of wildlife vehicle collisions (WVCs) is an increasing problem in Sweden with a calculated increase of 45 percent from 2015 to 2022. The highest measured number of WVCs occurred in 2021 with over 67,000 reported incidents, where only the payment for the search of wounded animals were approximately 60 million Swedish crowns.

  4. 3. Feasibility of reintroduction of European Bison (Bison bonasus) to Sweden with focus on traffic accidents

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Michael Topszewski; [2023]
    Nyckelord :wildlife-vehicle collision; risk prediction; reintroduction feasibility; european bison; Bison bonasus; moose; Alces alces; Human-wildlife conflict;

    Sammanfattning : The historical occurrence of European bison (Bison bonasus) in Sweden during the early Holocene emphasizes the ecological significance for a potential reintroduction. The European bison, the largest herbivore on the European continent, is a keystone species with a significant influence on ecosystem dynamics. LÄS MER

  5. 4. Airports Runway Monitoring System : Using Thermal Imaging Approach

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :SAI CHETAN POLURI; SAAROOPYA GUTIPALLI; [2022]
    Nyckelord :Background subtraction; Computer vision; Distance estimation; Machine Learning; Mammal detection; Thermal Imaging.;

    Sammanfattning : Context: On airport runways, monitoring is done by Precision Runway Monitor (PRM) method with the help of radar. Most of the airports are built near the forests so there is a greater chance of mam-mal intrusion onto the runways leading to massive accidents. LÄS MER

  7. 5. How Hunters’ Harvest Rate Varies in Response to Population Densities of Fallow Deer (Dama dama), Roe Deer (Capreolus capreolus), and Wild Boar (Sus scrofa)

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Felicia Skorsdal; [2022]
    Nyckelord :Bayesian statistics; Capreolus capreolus; Dama dama; Hunters’ harvest rate; Ungulate management; Spatiotemporal analysis; Sus scrofa;

    Sammanfattning : For many species, population size data is difficult to obtain or even unavailable. Therefore, estimations or indirect abundance measures of populations are crucial for ungulate management. Hunting has an important role in wildlife management, and is a partnership between state, landowners, and hunting communities. LÄS MER
