  1. 1. Analysis of winter wheat and leafhoppers for wheat dwarf virus : factors causing outbreaks of wheat dwarf disease

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Plant Biology (from 140101)

    Författare :Lina Karm Togo; [2024]
    Nyckelord :Sweden; Psammotettix alienus; DAS-ELISA; cloning; sequencing; BLASTn; BLASTx; MEGA; SDT;

    Sammanfattning : Wheat dwarf disease is caused by wheat dwarf virus (WDV) and is transmitted by the leafhopper Psammotettix alienus. The disease has been reported in many European countries, as well as in West Asia, China, and one country in North Africa. LÄS MER

  3. 2. Mängden död ved i värdekärnor i Söderåsens nationalpark

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Gustav Thurell; [2024]
    Nyckelord :volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Sammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  4. 3. Bivänliga växter i urban miljö : en granskning av växtutbudet från landskapsarkitektprogrammet

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Emma Asker Kling; Katarina Enskog Gripenvik; [2023]
    Nyckelord :Bin; humlor; vildbin; pollinatörer; pollinering; urban miljö; växtkännedom; ekosystemtjänst;

    Sammanfattning : Pollinatörerna är hotade globalt och i det svenska landskapet, och behöver hjälp för att överleva (Naturvårdsverket u.å.b). Den främsta orsaken till den negativa utvecklingen är förlusten och fragmenteringen av pollinatörernas livsmiljöer (Naturvårdsverket u. LÄS MER

  5. 4. Plant-soil feedbacks in boreal tree species

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Kailey Tentis; [2023]
    Nyckelord :plant-soil feedback; plant economic spectrum; biotic feedback; abiotic feedback; sterilization-inoculation experiment; conspecifics and heterospecifics;

    Sammanfattning : Plant-soil feedback (PSF) is important for understanding how plants influence the composition and abundance of soil biota and nutrients and how this affects plant growth. The plant economic spectrum (PES) also plays a role. LÄS MER

  7. 5. 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.
