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. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). LÄS MER
4. FÖDOPREFERENSER HOS BIN En jämförelse mellan pollenpreferenser hos nordiskt honungsbi och Buckfast
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : The original honeybee in Sweden, the European dark bee (Apis mellifera mellifera), was lost form the wild during the 19th century. The subspecies survived through beekeeping but began to be exchanged for other honeybees from the beginning of the 20th century and was almost locally extinct a century later. LÄS MER
5. “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 biologiSammanfattning : 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.
