1. Pollinator communities on a landscape complexity gradient in southern Sweden
Magister-uppsats, SLU/Dept. of EcologySammanfattning : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. LÄS MER
2. Competition between managed honeybees and wild bumblebees - Quantifying dietary overlap in semi-natural grasslands
Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. LÄS MER
3. “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.

4. Urbana ängar och deras betydelse för vilda pollinatörer
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Antalet vilda pollinatörer har minskat globalt och även i Sverige, där ett stort antal arter är rödlistade. Samtidigt visar studier att städer har blivit en viktig tillflyktsort för vilda pollinatörer då de kan innehålla en variation av livsmiljöer. LÄS MER
5. Fördelning av vilda pollinatörer med och utan närvaro av honungsbin i Västernorrland
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : My study focuses on how the pollination frequence for wild insect pollinators was influenced by the presence of honey bees. Man made beehives, with their thousands of honey bees, can potentially affect wild insect pollinators within 3 km radius. Several studies indicate that this competition will be disadvantageous for wild insect pollinators. LÄS MER
