  1. 1. Bats in Urban Sweden : A multiple regression analysis of bats’ relationship to urbanization

    Master-uppsats, Södertörns högskola/Miljövetenskap

    Författare :Nils Andersson Skog; [2021]
    Nyckelord :Urban ecology; Insectivorous bats; Chiroptera; Species composition; Bioindicator; Sustainable development;

    Sammanfattning : Human development continues to use up more physical space in the natural world, threatening the natural habitats of many organisms. To combat the loss of biodiversity science needs to explore what landscape features are important for different organisms so that we can incorporate these into the modern environment. LÄS MER

  2. 2. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic Scandinavia

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Elin Backström; [2021]
    Nyckelord :Physical Geography and Ecosystem analysis; Vegetation Greenness; Albedo; Fire; Frost Drought; Earth and Environmental Sciences;

    Sammanfattning : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. LÄS MER

  3. 3. Growth and management of Silver birch and Hybrid aspen in southern Sweden

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mari Tuvikene; [2021]
    Nyckelord :Betula pendula Roth; ; Populus × wettsteinii Hämet-Ahti = P. tremula L. × P. tremuloides Michx.; ; plantation; young stand; simulation; fertilization;

    Sammanfattning : Nowadays, the changing climate and the risks associated with it urge us to re-evaluate our silvicultural practices. Due to the increasing demand for wood and good economy amongst other factors, Swedish forest landscape is dominated by two species – Norway spruce Picea abies (L.) Karst. and Scots pine Pinus sylvestris (L. LÄS MER

  4. 4. How do saproxylic beetles differ in spruce (Picea abies) forests of different age? : A comparison between nature reserves and production forests, in county of Östergötland.

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Rebecca Petersen; [2021]
    Nyckelord :;

    Sammanfattning : Today, old growth forests are continuously decreasing, due to deforestation, threatening species to extinction. Species dependent on dead wood, different stages of decaying wood, large trees, and forest cover continuity have a particularly high risk of extinction, such as saproxylic beetle species. LÄS MER

  5. 5. Appropriate experimental design and pre-commercial thinning regime in Norway spruce stands on former agriculture lands in Latvia

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Aksels Edgars Loks; [2020]
    Nyckelord :management regime; heureka; randomized complete block design; density; economical rotation age; land expectation value;

    Sammanfattning : Recent decades Latvian land usage has change and lot of unused agricultural lands has been reforested. These areas show difference by increased growth from typical forest land, because of this trait stands need different silvicultural treatments, implementation time and intensity. LÄS MER
