  1. 1. The forgotten sand bee. A follow up on the status of the golden sand bee Andrena marginata in municipality of Mark, a decade later

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Monika Böttcher; [2024-03-19]
    Keywords : Golden sand bee; Andrena marginata; Devil´s bit scabious; Succisa pratensis; Oligolectic bees; Inventory; Meadow land; Conservation;

    Abstract : Over a decade ago, a conservation project aimed at preserving the endangered golden sand bee (Andrena marginata) populations in the Storån valley of the municipality of Marks was initiated. The species, red-listed in Sweden as well as in many other European country, specializes in pollen from Devil's bit. READ MORE

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

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

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

    Abstract : 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. READ MORE

  4. 4. Optical Communication using Nanowires and Molecular Memory Systems

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Thomas Kjellberg Jensen; [2024]
    Keywords : neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Abstract : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.
