1. Pollinator communities on a landscape complexity gradient in southern Sweden
University essay from SLU/Dept. of EcologyAbstract : 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. READ MORE

2. Competition between managed honeybees and wild bumblebees - Quantifying dietary overlap in semi-natural grasslands
University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Abstract : 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. READ MORE

3. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.

4. The importance of forest forage resources and a landscape perspective, managing bumblebees (Bombus) in Swedish forest-farmland
University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)Abstract : The Swedish forest has been transformed during the last hundred years, from semi-open forest of multiple tree species to dense production forest of mainly spruce and pine. This has led to alterations of species composition in the forest floor, reducing coverage of dwarf shrubs like Vaccinium myrtillus (European blueberry). READ MORE
