  1. 1. FOREST LANDSCAPE STRUCTURE OF CAPERCAILLIE (TETRAO UROGALLUS) LEK SITES IN NORTHERN SWEDEN : Analysis of lek site characteristics

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Agnes Blomgren; [2023]
    Nyckelord :capercaillie Tetrao urogallus ; habitat selection; forest landscape structure; lek site;

    Sammanfattning : The purpose of this study is to analyze which variables influence the capercaillie’s (Tetrao urogallus) selection of lek sites in northern Sweden by using remote sensing data. The lek site is a crucial area for the species’ reproductive success. LÄS MER

  3. 2. Wild boar habitat selection in south-central Sweden's forested habitats : effects of season and time

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Bengt Arvid Norström; [2023]
    Nyckelord :wild boar; habitat selection; GLMM; Sweden;

    Sammanfattning : How wild boar utilize space, interact, and affect its surroundings is critical for understanding their ecology. Wild boar populations have increased rapidly in Sweden and continue to expand its distributional range further north. LÄS MER

  4. 3. Associations between body size polymorphism in Arctic charr and benthic invertebrate communities – clues to mechanisms for population differentiation?

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

    Författare :Andreas Sund; [2022]
    Nyckelord :arctic charr; benthic invertebrates; polymorphism;

    Sammanfattning : Many fish populations in the north have divided into coexisting ecotypes that differ in body size. While such polymorphic fish populations have been studied for many years, the understanding of how different types of selection contribute to the formation of dwarf- and giant ecotypes remains limited.

  5. 4. Älgens och skogshönsens nyttjande av ett två år gammalt brandfält

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Alice Kårehagen; Hannah Sophie Jakob; [2022]
    Nyckelord :älg; Alces alces; skogshöns; Tetraoninae; brand; skogsbrand; älgbete; Ljusdal;

    Sammanfattning : Forest fires have had an extensive impact on our landscapes. Natural forest fires are especially important for the regeneration of pine and nutrition cycle in the boreal zone. LÄS MER

  7. 5. Dispersal and habitat use of juvenile brown trout (Salmo trutta) following egg stocking : -A case study in the river Rotälven, Sweden

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Jonathan Larsson; [2022]
    Nyckelord :brown trout; egg stocking; dispersal; alevin; fry; parr; redd; habitat preference; Öring; romutsättning; spridning; yngel; parr; habitatpreferens;

    Sammanfattning : Egg stocking in rivers and streams is a common measure to support and re-introduce salmonid populations. To ensure the success of egg stocking programs, knowledge of the early life stages of juveniles including dispersal ability and habitat preferences of fry is a prerequisite. LÄS MER
