  1. 1. Evaluating forest restoration effects on timing of avian dawn chorus in Ranomafana National Park, Madagascar

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

    Författare :Marjolein Pijper; [2023]
    Nyckelord :acoustic monitoring; forest restoration; dawn chorus; avian singing; bird monitoring; automatic recognition;

    Sammanfattning : Monitoring of forest restoration efforts is essential to ensure healthy, self-sustaining tropical rainforests. Passive acoustic monitoring is used to monitor vocal activity of birds, which play a key role in forest ecosystems as seed dispersers. LÄS MER

  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. Pearls as bycatch mitigation strategy for Harbour porpoise (Phoecena phoecena)

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Sara Gustafsson; [2020]
    Nyckelord :harbour porpoise; bycatch mitigation; acoustic reflector; pearl; gillnet; F-POD; click rate; click behaviour; inter-click-interval; terminal buzz; diel phase; GAM;

    Sammanfattning : One of the major threats to harbour porpoise population sustainability is thought to be the high incidence of bycatch specifically in gillnets. This study aims to examine the use of acrylic class pearls developed in an earlier study as acoustic reflectors on gillnets in an effort to increase their visibility to echolocating harbour porpoises in the lumpsucker fishery in Kattegatt.
