  1. 16. Bacterial and fungal growth in soil: The effect of temperature and substrate addition

    Författare :Stephanie Reischke; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacterial growth; Fungal growth; Respiration; Carbon loading; Glucose mineralisation; Temperature adaptation; Temperature sensitivity; Temperature dependence;

    Sammanfattning : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. LÄS MER

  3. 17. Interactions between ectomycorrhizal associations and bacteria

    Författare :Srisailam Marupakula; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Boreal forest podzol soils have vertically stratified horizons with different physico-chemical characteristics and high microbial diversity. Ectomycorrhizal fungi play key roles in accessing nutrients from both organic and mineral substrates. The role of associated bacteria in these processes is still poorly understood. LÄS MER

  4. 18. Comparing effects of endogenous and anthropogenic nitrogen supply on ectomycorrhizal fungi

    Författare :Karolina Jörgensen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Boreal forests are characterized by strong nutrient limitation and nitrogen is partic-ularly scarce. Ectomycorrhizal fungi acquire nitrogen from the soil in return for car-bon from their tree host and are, thus, pivotal mediators of carbon and nitrogen cy-cling. LÄS MER

  5. 19. The effect of simulated anthropogenic nitrogen deposition on the net carbon balance of boreal soils

    Författare :Nadia Maaroufi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Anthropogenic activities have globally increased nitrogen (N) deposition and carbon dioxide (CO₂) gas emissions. It is proposed that anthropogenic N deposition may increase the size of boreal forest CO₂ sink, because boreal ecosystems are N limited. LÄS MER

  7. 20. Fungal communities of West African ectomycorrhizal woodlands

    Författare :Brendan R. Furneaux; Martin Ryberg; Matthew Smith; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ectomycorrhizal fungi; West Africa; metabarcoding; Sudanian woodlands; community ecology; ethnomycology; edible mushrooms; fungi; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Ectomycorrhizal symbiosis is a widespread mutualist relationship between fungi and plants, often trees. It is most well-known in temperate and boreal forests, but also occurs in a variety of tropical ecosystems, including Sudanian savanna woodlands and gallery forests in West Africa. LÄS MER
