    Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.

  5. 24. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

    Författare :Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. LÄS MER

  7. 25. Managing agricultural nutrient leaching within the EC Water Framework Directive in Sweden

    Författare :Anna-Lena Bratt; Per Sandén; Martin Ljung; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nutrient leaching; agricultural pollution; C Water Framework Directive; water quality; legislation; övergödning; lantbruk; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Agricultural management practices geared towards reducing nutrient leaching are in focus for the research presented in this thesis. Critical measures for reducing diffuse pollution from the agricultural sector depend on decisions of individual farmers. LÄS MER
