  1. 6. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

    Författare :Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. LÄS MER

  3. 7. Samnyttjad mark och urbana allmänningar : En fallstudie av skyfallsanpassning i Malmö och Köpenhamn

    Författare :Per Larsson; Katarina Nylund; Peter Parker; Richard Ek; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban land use; urban commons; cloudburst; sewage system; flooding; Malmö; Copenhagen; Samnyttjande; allmänning; urban allmänning; skyfall; dagvatten; LOD; stadsutveckling; markanvändning; Malmö; Köpenhamn; Urban studies; Urbana studier;

    Sammanfattning : I avhandlingen analyseras möjligheter och hinder för samnyttjande av mark utifrån en fallstudie av skyfallsanpassning i Malmö och Köpenhamn. Som bakgrund står de klimatutmaningar i form av ökad framtida nederbörd och risk för översvämningar som städerna ställs inför, tillsammans med en tilltagande konkurrens om marken från allt fler behov.

  4. 8. Blue-green stormwater systems for citywide flood mitigation : Monitoring, conceptualization, modeling, and evaluation

    Författare :Salar Haghighatafshar; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blue-green measures; drainage system; flooding; flood mitigation; hydrodynamic modeling; rainfall-runoff; stormwater;

    Sammanfattning : Considering the growth in urbanization, leading to an increase in impervious surfaces, and the changing climate, enhancing the intensity and frequency of rainfall events, existing urban drainage networks—separate or combined sewer systems—are presumed to face substantially elevated hydraulic loads, causing pluvial floods in urban areas. There are several ways to address these challenges. LÄS MER

  5. 9. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Författare :Gösta Lilius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

  7. 10. Effects of climate change on boreal wetland and riparian vegetation

    Författare :Lotta Ström; Roland Jansson; Christer Nilsson; Sarah Gergel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomass; flooding; hydrologic niche; invasibility; riparian zone; riparian plant species; river margin; climate scenario; seed sowing experiment; species composition; species richness; transplant experiment; Terrestrial ecology; Terrestrisk ekologi;

    Sammanfattning : Models of climate change predict that temperature will increase during the 21th century and the largest warming will take place at high northern latitudes. In addition to warming, predictions for northern Europe include increased annual precipitation and a higher proportion of the precipitation during winter falling as rain instead of snow. LÄS MER
