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
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : 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. LÄS MER
2. Oligolectic bee species. An understudied group in Global Change impacts?
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : 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
3. DIFFERENCES ON THE IMPACTS AND ORIGINS OF POLLEN IN FOUR MAJOR SWEDISH CITIES BETWEEN 2014 AND 2019
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Allergies are widespread in the world and coming from various sources, one of the causes being airborne allergens and especially, pollen. The negative impact of pollen is enhanced by pollution and climate change which are some of the biggest issue humankind is facing today. LÄS MER
4. Optical Communication using Nanowires and Molecular Memory Systems
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : 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.

5. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. LÄS MER
