  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Lucy Chipondoro; [2024]
    Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

    Sammanfattning : 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. LÄS MER

  3. 2. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

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

    Författare :Ayesha Nagahage; [2024]
    Nyckelord :Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Sammanfattning : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  4. 3. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Emma Dahlstedt; [2023-08-18]
    Nyckelord :Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Sammanfattning : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. LÄS MER

  5. 4. The Valeriana officinalis aggregate in Sweden. A preliminary study.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Daniel Bäck; [2023-06-30]
    Nyckelord :;

    Sammanfattning : Common valerian (Valeriana officinalis L.) is a species of flowering plants native to Europe, the roots of which have been used in folk medicine for centuries. But due to high diversity in morphology and chromosome numbers, different populations in V. LÄS MER

  7. 5. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Ivan Ruzic; [2023-06-21]
    Nyckelord :heat wave; urban trees; NDVI; remote sensing;

    Sammanfattning : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. LÄS MER
