16. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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.

17. Mapping edge vegetation in connection to beech forest to locate potential habitats for red-listed beetles in Scania, Sweden
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The number of species classified as red-listed has increased by 11% between 2015 and 2020, with beetles and butterflies being especially affected. Among these are the vulnerable longhorned beetle (Stictoleptura scutellata) and the endangered false blister beetle (Ischnomera sanguinicollis). LÄS MER
18. Naturban : naturinspirerad gestaltning av en park längs Fyrisån i Uppsala
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Städer ligger ofta i områden med en naturligt hög biologisk mångfald. De globala klimatförändringarna innebär en ökad förekomst av extremväder vilket tillsammans med storskaliga monokulturella landskap utgör ett hot mot den biologiska mångfalden. LÄS MER
19. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden
Master-uppsats, Uppsala universitet/PaleobiologiSammanfattning : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.

20. “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.
