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

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

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

    Abstract : 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. READ MORE

  3. 2. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  4. 3. Heritability of methane emission in Swedish Red cattle in northern Sweden

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Lucy Chipondoro; [2024]
    Keywords : methane emission; heritability; swedish Red cattle; dairy cow;

    Abstract : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. READ MORE

  5. 4. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE

  6. 5. Can urban tree re-inventories inform future species selection? : diameter at breast height as an indicator for tree performance in Malmö municipality’s tree database

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Hannah Kit Kraynick Braegelmann; [2023]
    Keywords : DBH; ; diameter at breast height; tree inventories; tree re-inventories; urban forestry; species selection; tree management;

    Abstract : Using the inventory database of trees for Malmö municipality, Sweden, this study explored the potential of using the diameter at breast height (DBH) measurement in re-inventories, as a decision-making tool for species selection and management in urban forests. With the escalating pressures of urbanization and unpredictable climate change effects, there is an urgent need for urban forest managers to possess reliable tools that can facilitate the selection of resilient tree species capable of thriving in diverse and changing urban contexts.
