  1. 1. The effect of the COVID-19 lockdown on the spatial ecology of moose in an area with high recreational activity

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

    Författare :Maximilian Dörr; [2024]
    Nyckelord :Moose; Alces alces; habitat selection; tourism; human disturbance; activity; movement; speed; seasons; Covid-19; pandemic;

    Sammanfattning : In diverse landscapes, the coexistence of wildlife habitat requirements and human land use often leads to conflicts, posing challenges for sustainable species management. Recreational activities, especially in sparsely populated areas, frequently disturb wildlife behavior, necessitating a comprehensive assessment of anthropogenic impacts on habitats. LÄS MER

  3. 2. Resilience-building interventions in A refugee camp : A qualitative study  on the circumstances and interventions that promotes children's mental well-being in the context of a refugee camp

    Kandidat-uppsats, Umeå universitet/Institutionen för socialt arbete

    Författare :Ahmadullah Hakimy; [2023]
    Nyckelord :Refugee Children; refugee Camp; Al Zaatari refugee camp; Resilience-building interventions; Jordan;

    Sammanfattning : Abstract      Refugee children living in refugee camps are a vulnerable population at a high risk of developing mental health problems, behavioural issues, and being exposed to violence or trauma. However, not all children that experience these stressors of displacement develop negative outcomes. LÄS MER

  4. 3. Grönare gata på 25 kvadrat : en studie av utmaningar och möjligheter med biodiversitetsfrämjande parklets i urban miljö

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Amanda Freng Blümke; [2023]
    Nyckelord :parklet design; biodiversitet; pollinatörer; innovation; taktisk urbanism; växtdesign; ekologisk hållbarhet; SPUGS; urban ekologi; ekosystemtjänster; framtidsvisioner; ruderatmarker; naturen som förebild; torktåliga arter; sociala värden;

    Sammanfattning : Idag lever nästan 90% av Sveriges befolkning sina liv i urbana miljöer. Eftersom expansionen i många städer blivit begränsad riktas i stället blickarna mot den täta staden som lösning på problemet. Men med förtätning följer också många utmaningar. LÄS MER

  5. 4. Assessing the accuracy of a spatial model of habitat suitability for Calypso bulbosa

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Michael Doorly; [2023]
    Nyckelord :Calypso bulbosa; norna; orchid; conservation; Sweden; alpine region; habitat suitability; distribution model; ecology; biodiversity;

    Sammanfattning : Calypso bulbosa is a rare and visually striking orchid that grows in older mesic to moist forests in the northern half of Sweden. C. bulbosa is red listed as a threatened species (Vulnerable, VU) with a reduction in numbers linked to modern forestry practices and exacerbated by the warming climate. LÄS MER

  7. 5. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Evelina Andersson; [2023]
    Nyckelord :spruce bark beetle; population dynamics; conservation areas; biodiversity; natural enemies; species richness; managed forests; woodland key-habitats; nature reserves;

    Sammanfattning : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.
