  1. 1. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Shakhera Akter Shimu; [2023]
    Nyckelord :Climate change; plant phenology; phenological traits; phenology change; cumulative temperature; phenotypic plasticity; genotypic variation;

    Sammanfattning : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. LÄS MER

  3. 2. The effect of life history and weather on onset of flowering and length of flowering period of agricultural weeds

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Amanda Karpaty Wickbom; [2023]
    Nyckelord :global warming; agricultural weeds; first flowering; flowering phenology;

    Sammanfattning : With a warming climate and the usage of monocultures in food production it is possible we may face more issues concerning food insecurity in the future as pollinators struggle to find food in agricultural landscapes. Therefore, it is of value to know whether common agricultural weeds are important sources of food for pollinators. LÄS MER

  4. 3. Körsbärsträd i ett förändrat klimat : konsekvenser av ett varmare svenskt vårvinterklimat för körsbärsträdens blomning

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Emelie Karlberg; Åse Hiltunen Nilsen; [2023]
    Nyckelord :Frostskador; knoppsprickning; fenologi; blomning; körsbär; klimatförändringar; svenskt klimat; vårvinter; fluktuerande temperaturer; Prunus;

    Sammanfattning : Körsbärsblom är för många ett tydligt tecken på att våren är här. Den vackra blomningen är populär hos många och kanske är det anledningen till att körsbärsträd är så vanligt förekommande i svenska städer. LÄS MER

  5. 4. FLOWERING TIME DEPENDENCE ON MICROCLIMATE ACROSS AN ELEVATIONAL GRADIENT IN ARCTIC PLANT COMMUNITIES

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Maria Pavolotskaia; [2022-07-06]
    Nyckelord :The Arctic; flowering time; flowering phenology; elevation; elevational gradient; temperature; snowmelt; snow cover; microclimate.;

    Sammanfattning : The Arctic is the fastest-warming region on Earth. Arctic plant communities are highly sensitive to temperature change; temperature-dependent advancement of flowering dates has already been observed in the Arctic. Flowering time is critical for reproductive success. LÄS MER

  7. 5. Evolution of flowering time in a changing environment

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Emmy Sköld; [2021]
    Nyckelord :flowering time; evolution; Arabidopsis thaliana; environmental effects; adaptations; flowering phenology;

    Sammanfattning : How come the same species of plants can naturally occur under various conditions in different parts of the world? A plant's ability to adapt in response to a changing climate hinges on the presence of genetic variation in traits, such as flowering phenology. In this study, I examine whether flowering start varies genetically within populations and compare this variation to differences between populations. LÄS MER
