  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. Brain morphology and behavioural variation in relation to habitat and predation risk in minnows (Phoxinus phoxinus)

    Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Marina Gallego González; [2022]
    Nyckelord :brain size; Ecology; environmental complexity; European minnow; fish; geometric morphometrics; morphological divergence; phenotypic plasticity; schooling.;

    Sammanfattning : So far, research on inter- and intraspecific teleost brain plasticity across different freshwater environments has been widely conducted. However, insights of brain morphological variation on social and predator avoidance behaviours are lacking. LÄS MER

  4. 3. Impact of experimental soil moisture manipulation on tropical tree seedling demographic fates and functional traits

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för ekologi och genetik

    Författare :Roel Lammerant; [2021]
    Nyckelord :Tropical forest; Drought; Seedlings; Experimental;

    Sammanfattning : In tropical regions, climate change is predicted to lead to increased drought frequency and intensity. The extent to which this will shift the functional diversity of tropical tree communities is unknown due to a limited understanding about the response of seedlings to variable soil moisture. LÄS MER

  5. 4. The Role of Juvenile Hormone and Ecdysone in Wing Morph Determination in the Wing Polyphenic Water Strider, Gerris buenoi

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Kevin Nielsen; [2021]
    Nyckelord :Wing polyphenism; Phenotypic plasticity; Water striders; Gerris buenoi; Ecdysone; Juvenile hormone; RNAi;

    Sammanfattning : In this laboratory study, the role of juvenile hormone (JH) and ecdysone in regulating wing polyphenism was investigated in the non-model organism Gerris buenoi. Topical application of the JH analog methoprene elicited reduced pronotum, wing defects, and nymphal-adult intermediates but no changes to wing morph. LÄS MER

  7. 5. Time Constraint and Genetic (Phenotypic) Variation in Wing Shape in a Damselfly Along a Latitudinal Gradient

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Meagan Tunon; [2020]
    Nyckelord :Damselfly; time constraint; wing shape; morphology; climate change;

    Sammanfattning : This degree project examined the effect of time constraint on wing shape and phenotypic variation in wing shape along a latitudinal gradient in the damselfly species Lestes sponsa. Fore and hind wings from individuals originating from three different latitudes: North (66°N), Central (59°N) and South (54°N) Europe were treated with their native temperature and photoperiod.
