  1. 1. Co-existence and conflict in a changing forest landscape: A case study of Maskaure reindeer herding district

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Tove Berg; [2022]
    Nyckelord :Reindeer husbandry; Forestry; Political Economy; Resource production; Landscape; Access; Maskaure; Sweden; Social Sciences;

    Sammanfattning : Land use for reindeer husbandry and forestry are overlapping in large areas of northern Sweden. This co-location is characterized by dynamics in which the forest industry owns the land and the power to transform it, and the reindeer industry possesses a user-right for reindeer grazing and herding.

  3. 2. Host plant selection in closely related butterfly species due to reproductive interference: Modelling a tritrophic system

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Alexandros Bantounas; [2021]
    Nyckelord :reproductive interference; habitat selection; modelling; phytophagous insects;

    Sammanfattning : Host plant selection is an important process during the life cycle of lepidopterans, providing ovipositing sites for adults and food resources for the larvae. The processes behind host plant selection have been extensively studied, especially in closely related species in the context of niche separation. LÄS MER

  4. 3. Villain or scapegoat: New perspectives towards understanding the current management of the human-elephant conflict in Sri Lanka

    Master-uppsats, Lunds universitet/LUCSUS

    Författare :Annemarie Russ; [2019]
    Nyckelord :human-elephant conflict; social-ecological systems; species co-existence; wildlife conservation; sustainability science; Sri Lanka; Social Sciences;

    Sammanfattning : The conflict between humans and elephants (HEC) in Sri Lanka is severe. Due to habitat fragmentation and resource reduction elephants increasingly roam in areas with human settlements. These human-elephant interactions often lead to losses on both sides, which should be prevented. LÄS MER

  5. 4. Importance of bumble bee community evenness for crop pollination : a simulation analysis of Swedish red clover seed production

    Magister-uppsats, SLU/Dept. of Ecology

    Författare :Vivek Babu; [2018]
    Nyckelord :bumble bee; Bombus; community; evenness; biodiversity-ecosystem function; diversity-stability; diversity-productivity; overyielding; productivity; stability; biodiversity; selection effect; species asynchrony; portfolio effect;

    Sammanfattning : The red clover seed production systems are dependent on pollinators for increase in red clover seed yield and its stability. When compared to domesticated honey bees, the wild bumble bees are highly efficient in pollinating the red clover crop due to its relatively longer tongue length. Longer dependence on single pollinator species i.e. LÄS MER

  7. 5. Stress hos tamdjur orsakad av rovdjur

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Maja Månsby; [2013]
    Nyckelord :stress; tamdjur; rovdjur; glukokortikoider; rovdjursangrepp; kortisol;

    Sammanfattning : Det finns fem fredade rovdjur i Sverige: björn, varg, lo, järv och kungsörn. Riksdagen har beslutat att det ska finnas livskraftiga populationer av dessa djur i landet och rovdjursstammarna har ökat den senaste tiden. En viktig orsak till konflikt mellan människor och de stora rovdjuren är rovdjurens predation på våra tamdjur. LÄS MER
