  2. 11. Tree phenology modelling in the boreal and temperate climate zones : Timing of spring and autumn events

    Author : Cecilia Olsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plant phenology in the boreal and temperate climate zones is synchronised with seasonal changes in temperature and photoperiod. For deciduous trees, timing of budburst and leaf colouring define the growing season length and express adaptations to trade-offs in growth and risks. READ MORE

  4. 12. Deuterium isotopomers as a tool in environmental research

    Author : Tatiana Betson; Jürgen Schleucher; Peter Högberg; Richard Robins; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; deuterium; NMR; isotopomers; CO2 response; climate reconstruction; persistent pollutants; stable isotopes; Environmental chemistry; Miljökemi;

    Abstract : This thesis describes the development and the use of quantitative deuterium Nuclear Magnetic Resonance spectroscopy (NMR) as a tool in two areas of environmental research: the study of long term climate-plant interactions and the source tracking of persistent organic pollutant. Long-term interactions between plants and climate will influence climate change during this century and beyond, but cannot be studied in manipulative experiments. READ MORE

  5. 13. On urbanisation and birds : Insights from a molecular and physiological perspective

    Author : Pablo Salmon; Evolutionär ekologi; []
    Keywords : Air Pollution; Antioxidants; Birds; great tit Parus major; Local adaptation; Nitrogen oxides; Oxidative stress; Parallel evolution; Survival; Telomere dynamics; Telomeres; Urbanisation;

    Abstract : Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. READ MORE

  6. 14. High-resolution imaging of kidney tissue samples

    Author : David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Abstract : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  7. 15. Root system of seabuckthorn (Hippophaë rhamnoides L.) : morphology, metabolism and gene expression

    Author : Syed Rehmat Ullah Shah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nutrient availability is one of the limiting factors for plant growth and development, and the nutrients on Earth are unevenly distributed. To overcome this, plants adapt by modifying their morphology and physiology, especially of the root system. Seabuckthorn is a small tree growing in temperate regions of Europe and Asia. READ MORE
