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. An attempt to promote ground-nesting bees in an urban landscape. Investigating the use of sand beds as a conservation effort.
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : Pollinators provide crucial services for the ecosystems by pollinating around 80-90% of all plants. However, pollinating insects are declining worldwide which may cause a parallel decline in plant species leading to large biodiversity losses. LÄS MER
4. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskapSammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER
5. Privatträdgårdens potential som resurs för gynnande av pollinationssamhällen
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : I detta arbete undersöks hotbilden mot de viktigaste pollinatörerna i Sverige, påverkansfaktorer samt vilka handlingsalternativ som finns för privatpersoner med engagemang i frågan. I dagsläget är många viktiga pollinatörer globalt och nationellt hotade, och därmed också de ekosystemtjänster som vi människor drar nytta av dagligen. LÄS MER
