  1. 16. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Författare :Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Sammanfattning : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. LÄS MER

  3. 17. Invasive fungal infections in immunocompromised hosts : epidemiology and diagnostics

    Författare :Anders Krifors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This doctoral project aimed to attain a more in-depth knowledge of the epidemiology and diagnosis of invasive fungal infections. In Study I, we evaluated the diagnostic performance of PCR/ESI-MS. LÄS MER

  4. 18. Microbial temperature dependences in soil: The belowground feedback to climate change

    Författare :Dániel Tájmel; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soil microbial community; microbial growth; microbial respiration; temperature dependence; climate change;

    Sammanfattning : Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. LÄS MER

  5. 19. Soil salinity as a driver of microbial community structure and functioning

    Författare :Kristin Rath; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Sammanfattning : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

  7. 20. Approaches to Species Delineation in Anamorphic (mitosporic) Fungi : A Study on Two Extreme Cases

    Författare :Olga Vinnere; Siv Andersson; Jamshid Fatehi; Berndt Gerhardson; Stephen B. Goodwin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; fungal taxonomy; Colletotrichum acutatum; Mycelia Sterilia; Phoma; Campanella; phylogeny; species concept in fungi; Biologi; Biology; Biologi;

    Sammanfattning : Since the beginning of mycology, studies of species concept in fungi have been mainly based on morphology, partially due to the history of mycology as part of botany. Current advances in biochemical and molecular research have provided mycologists with powerful tools that can be used for delineation of fungal taxa. LÄS MER
