  2. 11. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

    Author : Pushan Bag; Stefan Jansson; Fransis Andre Wollman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scots Pine; Norway spruce; Photosynthesis; Winter adaptation; biologisk kemi; biological chemistry; biology; biologi; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik;

    Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

  4. 12. Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches

    Author : Shubhangi Lamba; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Climate change; Acclimation; MAESTRA; Whole Tree Chamber;

    Abstract : The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation differ from those of most temperate regions. READ MORE

  5. 13. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)

    Author : Helena Eklöf; Pär K. Ingvarsson; Xiao-Ru Wang; Carolina Bernhardsson; Katri Kärkkäinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Picea abies; forestry; genetic diversity; seed orchards; forest management; WGS; GBS; sequencing; PoolSeq; capture probes; genetic differentiation;

    Abstract : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. READ MORE

  6. 14. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce

    Author : Xi Wang; Pär K. Ingvarsson; Carolina Bernhardsson; Xiao-Ru Wang; Nathaniel Street; Tanja Pyhäjärvi; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; whole-genome resequencing; variant calling; genetic linkage map; nucleotide diversity; natural selection;

    Abstract : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. READ MORE
