  1. 21. Pattern and process in Alpine communities of the Northwestern Caucasus

    Författare :Galina A. Pokarzhevskaya; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; biodiversity; life forms; life-history strategy; microtopography; snowbedcommunities; snow melting gradient; tussock; vegetative mobility; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Patterns in vegetation reflect certain processes affecting plant communities. The present work aims at describing patterns and revealing mechanisms operating in alpine vegetation belonging to four vegetation types: alpine lichen heaths, Festuca varia grasslands, Geranium-Hedysarum meadows and snowbed communities.

  3. 22. Nutrient use strategies of plants of various life-forms in a subarctic environment : Nutrient conservation as an adaption to infertile habitats

    Författare :Rolf Lutz Eckstein; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Mean residence time; Nutrient productivity; Nutrient use efficiency; Plant strategies; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Plant performance in relation to limiting nutrients was analysed using the concept of nutrient use efficiency (NUE). NUE can be decomposed into (1) the nutrient productivity (aNP) and (2) the mean residence time (MRT). LÄS MER

  4. 23. Spatial Models of Gene Patterns in Plants

    Författare :André Larsson; Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; []
    Nyckelord :computational morphodynamics; gene regulation; spatial models; plants; development; auxin; meristem; Fysicumarkivet A:2017:Larsson;

    Sammanfattning : The growth and development of plants exhibits a striking symmetry, visible in the regular arrangement of leaves and flowers. Plant development is carefully controlled at the molecular level by gene regulatory networks, and the symmetry of plants can be observed also in the molecular patterns of gene expression. LÄS MER

  5. 24. The puzzle of forestry and cervid interactions : a missing piece is in the understory

    Författare :Laura Juvany Canovas; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Shrubs of the family Ericaceae, including bilberry (Vaccinium myrtillus), cowberry (V. vitisidaea) and heather (Calluna vulgaris), often dominate the understory in Eurasian boreal and cold-temperate forests. LÄS MER

  7. 25. Biological control of plant-parasitic nematodes by the fungus Clonostachys rosea

    Författare :Mudassir Iqbal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant diseases caused by plant-parasitic nematodes are serious constraints to sustainable crop production due to high yield losses, the persistent nature of these nematodes and a lack of efficient control methods. Biological control is a promising approach to reduce plant diseases caused by nematodes. LÄS MER
