  1. 1. How do rainfall patterns change microbial induced carbon dynamics in soil?

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Maria João Silva; [2023]
    Nyckelord :drying and rewetting; bacterial growth; fungal growth; annual crops; perennial crops; soil depth; climate change; biotechnology; Biology and Life Sciences;

    Sammanfattning : Climate change is changing the precipitation patterns around the globe, leading to more extreme weather events like severe drought and heavy rainfalls. These events are intrinsically related to soil moisture fluctuations, which strongly modulates carbon fluxes in terrestrial ecosystems. LÄS MER

  3. 2. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

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

    Författare :Franklin Lee Harris; [2023]
    Nyckelord :microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. LÄS MER

  4. 3. Våtmarkers relation till skogsbränder : En litteraturstudie och GIS-analys av intakta och utdikade våtmarker i borealt svenskt skogslandskap

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Rufus Rune; Emilia Tidblad; [2023]
    Nyckelord :wetland; wildfire; peat; fire spread; GIS; drainage; våtmark; skogsbrand; torv; brandspridning; GIS; utdikning;

    Sammanfattning : Som en följd av global uppvärmning blir det allt viktigare med resiliens mot klimatkrisens konsekvenser, däribland mer frekventa skogsbränder. Då våtmarker kan behålla vatten och ge resiliens mot torka och bränder är det intressant att undersöka relationen mellan våtmarker och skogsbränder. LÄS MER

  5. 4. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anna Engman; [2022]
    Nyckelord :peatland; peat volume change; ecohydrology; specific storage; peatland age; torvmark; myr; torvvolymförändring; ekohydrologi; specifik magasinkoefficient; ålder;

    Sammanfattning : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. LÄS MER

  7. 5. Bacterial and fungal responses to drying and rewetting using bronopol or cycloheximide as inhibitors

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Simon Lin; [2019]
    Nyckelord :Drying-rewetting; respiration; growth rate; growth response; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : Microbial decomposers breakdown soil organic matter, releasing carbon dioxide (CO2) to the atmosphere. This release of CO2 could therefore contribute to future climate change. LÄS MER
