  1. 1. 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.

  4. 3. Flower preferences among weed-visiting insects in field edges

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

    Författare :Isolde Galin; [2021]
    Nyckelord :arable field; flower preference; pollinator; weeds;

    Sammanfattning : The increased improvement of weed control throughout the years has led to a decrease in the amount of weed in arable fields. Weeds can be a source of pollen and nectar. Pollinating insects are dependent on a variety of plants for nectar and pollen. LÄS MER

  5. 4. Analysis of Selection and Genetic Drift in a Dioecious Plant : Spatial Genetic Structure and Selection in Phenotypic Traits in a Young Island Population of Silene dioica

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

    Författare :Bea Angelica Andersson; [2014]
    Nyckelord :selection; genetic drift; quantitative trait; FST; PST; drift; evolution; founder event; gene flow; Silene dioica; dioecious; substructure; subpopulation; phenotypic trait; pollinator preference; Skeppsvik; Sweden; succession;

    Sammanfattning : Selection and genetic drift are often competing forces in shaping genetic structure in populations. Genetic drift will often effectively cancel out the effect of selection when population sizes are small, such as in colonizing island populations. LÄS MER
