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. 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
3. Comparison of drone ecology and behavior between Apis mellifera mellifera and the hybrid Buckfast in southwestern Sweden
Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Most research on the biology of the western honey bee (Apis mellifera) focuses on the worker bees, but knowledge about drones is lacking despite their important role in mating with a virgin queen. Available information about their ecology and behavior are mainly based on direct observations in need of intensive experience and knowledge about honey bees. LÄS MER
4. 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
