  1. 1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Patricia Salén; [2024]
    Nyckelord :Ectomycorrhiza; drought; Suillus;

    Sammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER

  3. 2. ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT

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

    Författare :Robert Klein; [2023-01-19]
    Nyckelord :urban climate; heat stress; mean radiant temperature; SOLWEIG; urban vegetation; urban planning;

    Sammanfattning : Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly important. LÄS MER

  4. 3. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

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

    Författare :Krishani Devika Wijesinghe Sinhalage; [2023]
    Nyckelord :sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Sammanfattning : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

  5. 4. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Yixian Chen; [2023]
    Nyckelord :density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Sammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER

  7. 5. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

    Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :Annika Silvennoinen; [2023]
    Nyckelord :Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

    Sammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER
