  1. 1. Hur påverkas fladdermöss av bytet till LED från traditionella ljuskällor? : En jämförelse mellan olika ljuskällors påverkan på fyra arter av fladdermöss i Karlstads kommun

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jennifer Lehikoinen; [2023]
    Nyckelord :Chiroptera; bats; LED; light pollution; artificial lighting; ALAN; Chiroptera; fladdermöss; LED; ljusföroreningar; artificiell belysning;

    Sammanfattning : Ljusföroreningar är ett stort framväxande problem och då fladdermöss oftast är nattaktiva erfaras de ingå i den taxa som påverkas mest. LED-belysning blir allt vanligare i gatubelysning och utstrålar bland annat inget UV-ljus jämfört med traditionella ljuskällor som utstrålar UV-ljus och därmed förändrar insekters- och potentiellt fladdermössens beteende.

  3. 2. Using the AudioMoth - a novel passive acoustic monitoring technology - to monitor bat diversity in a rewilded landscape

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Koen Pronk; [2022]
    Nyckelord :passive acoustic monitoring; bioindicator; chiroptera; audioMoth; trophic rewilding;

    Sammanfattning : Ecosystem restoration through the reintroduction of grazers is gaining interest across Europe. Large herbivores are associated with landscape heterogeneity, restoration of trophic cascades and biodiversity. LÄS MER

  4. 3. Analysis of behavioural changes of wildlife in urban environments:comparison of observable patterns amongst species groups

    Magister-uppsats,

    Författare :Natalia Rubio Mantilla; [2022]
    Nyckelord :urban areas; wildlife; behaviour; changes; mammals; birds;

    Sammanfattning : Through a literature review I have carried out an analysis of wildlife behavioural changes in urban areas. The aim is to determine the behavioural changes that wild species have undergone. This study has been carried out for species belonging to the orders Carnivora, Chiroptera, Rodentia, Passeriformes, Falconiformes and Strigiformes. LÄS MER

  5. 4. Bats in Urban Sweden : A multiple regression analysis of bats’ relationship to urbanization

    Master-uppsats, Södertörns högskola/Miljövetenskap

    Författare :Nils Andersson Skog; [2021]
    Nyckelord :Urban ecology; Insectivorous bats; Chiroptera; Species composition; Bioindicator; Sustainable development;

    Sammanfattning : Human development continues to use up more physical space in the natural world, threatening the natural habitats of many organisms. To combat the loss of biodiversity science needs to explore what landscape features are important for different organisms so that we can incorporate these into the modern environment. LÄS MER

  7. 5. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Esnart Emma Bwalya Chibwe; [2021]
    Nyckelord :sexual segregation; Daubenton’s bat; Myotis daubentonii; landscape analysis; habitat selection; foraging;

    Sammanfattning : Sexual segregation is a phenomenon present in many vertebrate taxa, including the bat order Chiroptera. Sexual segregation is a social and/or habitat separation based on sex and is driven by varying causes such as sexual dimorphism, resource and physiological limitations, predator avoidance and many other factors.
