  1. 1. Temporal, climatic and spatial variation in the distribution and activity patterns of the raccoon (Procyon lotor) in Hainich National Park, Germany

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

    Författare :Maria Grüneberger; [2022]
    Nyckelord :raccoon; procyon lotor; hainich National Park; canopy Walk; camera trapping; nocturnality; ground temperature; habitat preference; european beech; fagus sylvatica; anthropogenic influence;

    Sammanfattning : The raccoon (Procyon lotor) has been a part of German fauna since the 1920s, following a number of releases and escapes from captivity. This study intends to investigate the distribution and activity patterns of this non-native mesopredator in Hainich National Park, which lies in Central Germany, in-between 3 core areas of established raccoon populations.

  3. 2. Migration and activity of the eastern black-backed jackal (Canis mesomelas schmidtii) in Ol Pejeta, Kenya

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

    Författare :Julia Hedman Wallin; [2022]
    Nyckelord :black-backed jackals; Kenya; activity; weather; moon; illumination;

    Sammanfattning : This study examined the effects of weather during the day and illumination at night on the migration activity of the eastern black-backed jackals (Canis mesomelas schmidtii) in Ol Pejeta, a wildlife conservancy in Kenya, from October 2015 to December 2019. Jackal ecology is an understudied subject where focus has been directed to a sub-specie of black-backed jackals in southern Africa, with different animals, seasons, and habitats than to those in Ol Pejeta and eastern Africa.

  4. 3. The effects of eutrophication and browning on prey availability and performance of the three-spined stickleback (Gasterosteus aculeatus)

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Olivia Bell; [2021]
    Nyckelord :Baltic Sea; benthic habitats; body growth; climate change; coastal areas; diet; fish; stickleback; zooplankton;

    Sammanfattning : Shallow coastal areas often have high productivity and diversity, in part due to the high availability of light and nutrients. At the same time, they are exposed to multiple environmental pressures, such as browning and eutrophication. LÄS MER

  5. 4. Causes of trends in abundance of mesopredators in the Kattegat Sea
