    Sammanfattning : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. LÄS MER

  5. 4. Pappersgarn, framtidens fiskenät?

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Linnea Alkin; Saga Ingerholt; [2023]
    Nyckelord :Fishing gear; sustainability; crayfish trap; micro plastics; degradability; paper yarn; product development; textile technology; ghost fishing.; Fiskeutrustning; hållbarhet; kräftmjärde; mikroplaster; nedbrytbarhet; pappersgarn; produktutveckling; textilteknik; spökfiske.;

    Sammanfattning : Textilindustrin är i behov av nya material som kräver mindre resurser än konventionellt använda material som exempelvis syntet- och bomull. Syntetiska material har en negativ påverkan på miljön, bland annat på grund av den mängd mikroplaster som släpps ut i naturen vid produktion och användning (Nagamine, Kobayashi, Kusumi & Wada 2022).

  7. 5. 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.
