  1. 1. Oligolectic bee species. An understudied group in Global Change impacts?

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

    Författare :Monika Böttcher; [2024-03-19]
    Nyckelord :Solitary bee; global change; oligolecty; red list; taxonomy;

    Sammanfattning : Global change is considered the primary cause of the decline in bees worldwide, posing a significant threat to crucial pollination services they provide, carrying negative economic and ecological implications. Despite the extensive research conducted on the responses of bee communities to anthropogenic impacts, the focus has predominantly been on commercially interesting bees. LÄS MER

  2. 2. Bivänliga växter i urban miljö : en granskning av växtutbudet från landskapsarkitektprogrammet

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

    Författare :Emma Asker Kling; Katarina Enskog Gripenvik; [2023]
    Nyckelord :Bin; humlor; vildbin; pollinatörer; pollinering; urban miljö; växtkännedom; ekosystemtjänst;

    Sammanfattning : Pollinatörerna är hotade globalt och i det svenska landskapet, och behöver hjälp för att överleva (Naturvårdsverket u.å.b). Den främsta orsaken till den negativa utvecklingen är förlusten och fragmenteringen av pollinatörernas livsmiljöer (Naturvårdsverket u. LÄS MER

  3. 3. “What’s the buzz with bilberries?” – Bilberry pollinator community structure and function in relation to forest type and habitat structure

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Jacob Björnberg; [2022]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Over the last century, Swedish forests have undergone rapid land-use change due to intensification of management practices for timber production and the introduction of monocultures, which have resulted in considerable habitat loss and negative impacts to biodiversity. Insects form a significant component of forest biodiversity, yet forest-dwelling pollinators remain understudied, and little is known about how management strategies affect forest insect pollinator communities.

  4. 4. Complementary sex determination in a solitary bee : Mapping candidate sex determination loci and associated genes

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sara Magnusson; [2022]
    Nyckelord :Osmia bicornis; solitary bee; sex determination; Csd; Fem; complementary sex determination; hymenoptera;

    Sammanfattning : The molecular mechanism of complementary sex determination in the haplodiploid organisms is poorly understood and has only been described in the honeybee Apis mellifera. In the haplodiploid system, males develop from unfertilized eggs and females from fertilized eggs. However, in some rare cases, diploid males develop from fertilized eggs. LÄS MER

  5. 5. Flight phenology of oligolectic solitary bees are affected by flowering phenology

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Anna Palm; [2021]
    Nyckelord :Flight phenology; Flowering phenology; Global warming; Oligolectic; Solitary bee;

    Sammanfattning : Understanding the relationships between solitary bees’ flight phenology and flowering phenology is important in the context of global warming. Using Swedish citizen science data, observations of oligolectic solitary bees and flowering phenology were used together with temperature data. LÄS MER
