  1. 1. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clàudia Fernández Mestre; [2023]
    Nyckelord :Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Sammanfattning : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. LÄS MER

  3. 2. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Johan Per Michael Svedin; [2022]
    Nyckelord :Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

    Sammanfattning : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.
