    Abstract : All living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. READ MORE

  2. 2. Nitrogen, parasites and plants key interactions in boreal forest ecosystems

    University dissertation from Umeå : Umeå universitet

    Author : Joachim Strengbom; Umeå universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical loads; Deschampsia flexuosa; amino acids; mycorrhizal fungi; natural enemies; N deposition; N limitation; vegetational composition; Valdensia heterodoxa; Vaccinium myrtillus;

    Abstract : In the work described in this thesis I studied how increases in nitrogen (N) inputs may affect plant community structure in boreal forest understorey vegetation. These phenomena were investigated in N fertilization experiments and along a national N deposition gradient. READ MORE

  3. 3. Retention forestry as a conservation measure for boreal forest ground vegetation

    University dissertation from Umeå : Umeå universitet

    Author : Samuel Johnson; Sveriges lantbruksuniversitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The boreal forest is prone to natural disturbances, especially fire. Despite this, the disturbance caused by forest management is shown to have a severe effect on the system’s biodiversity. READ MORE

  4. 4. Interactions between gray-sided voles (Clethrionomys rufocanus) and vegetation in the Fennoscandian tundra

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Jonas Dahlgren; Umeå universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gray-sided voles; tundra vegetation; trophic cascades; plant-herbivore interactions; bilberry; plant communities; herbivory; plant resistance; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Terrestrial ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Terrestisk ekologi;

    Abstract : I have, in this thesis, studied the interactions between gray-sided voles (Clethrionomys rufocanus) and tundra vegetation, on islands in, and mainland sites close to the lake Iešjávri, in northern Norway. As isolated islands are virtually free of predation, I have been able to compare plant-herbivore interactions in the presence and absence of predators. READ MORE

  5. 5. Gut microbiota to counteract metabolic disorders and neuroinflammation : Impact of dietary factors and their potential to prevent Alzheimer’s disease

    University dissertation from Department of Food Technology, Lund University

    Author : Nittaya Marungruang; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018]

    Abstract : Alzheimer’s disease (AD) is the most common form of dementia. Increased accumulations of senile plaques and tangles are the known neuropathological hallmarks of AD. However, the exact triggers for such protein accumulations, leading to cognitive impairment and important morphological alteration in AD, are still elusive. READ MORE
