1. Bland granar och grannar : Ansvar och risk för granbarkborreangrepp i skog
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Juridiska institutionenSammanfattning : This thesis discusses the responsibility of and risk for infestations of spruce bark beetle. The spruce bark beetle, Ips typographus, is a natural part of the Swedish forest ecosystem but causes severe financial damage in forestry. Since 2018, the spruce bark beetle infestations have been substantial in Sweden. LÄS MER
2. Pathways to resilient apple orchards –Economic and ecological aspects of Integrated Pest and Pollination Management
Master-uppsats, Stockholms universitet/Stockholm Resilience CentreSammanfattning : Apple orchards as social-ecological systems provide high value crops and habitat for a variety of species. Yields are influenced by pest control and pollination services, and profit-oriented management often motivates the use of inputs, e.g., pesticides, to complement or replace these services. LÄS MER
3. Integrerat växtskydd i stadsmiljö : en undersökning av förutsättningar för en hållbar skötsel av grön infrastruktur
Kandidat-uppsats, SLU/Dept. of Plant Protection BiologySammanfattning : Den ökade urbaniseringen i världen har resulterat i en fragmentering av det naturliga landskapet. Som ett resultat har detta lett till förlust av habitat, en minskad artdiversitet och en påverkan på ekosystemtjänster som är nödvändiga för människans välbefinnande. LÄS MER
4. Intercropping oats with annual clovers : effects on yields and aspects of biodiversity
Master-uppsats, SLU/Dept. of EcologySammanfattning : The use of fertilizers, pesticides and herbicides has contributed to greatly increase the crop yields per hectare. Humanity has become reliant on artificial inputs overshadowing usage of resources from ecosystem services that we continue to weaken further, by using agricultural practises decreasing landscape and species diversity.

5. The natural pest control potential of different landscapes : mapping the ecosystem service in three regions of Sweden
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Natural pest control describes the process of natural enemies suppressing pests and thus reducing crop damage and stabilizing yields. How well these beneficial arthropod predators and parasitoids can thrive in a landscape is influenced by the land-use types in the vicinity, such as forest patches, pastures, or agricultural fields, and their ability to provide resources.
