Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Krynickillus melanocephalus was first seen in Sweden 2015. It is now labeled as an invasive species and it potentially poses a threat to the ecosystem, but the slug has not yet shown to have great negative impact in gardens and agricultural fields. There is limited ecological knowledge about the species. LÄS MER
2. Direct and indirect effects of roe deer (Capreolus capreolus) herbivory on an island population of Chequered blue butterfly (Scolitantides orion).
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Herbivory by ungulates is a known agent of disturbance in many ecological systems around the globe.

5. Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?
Magister-uppsats, SLU/Dept. of Plant Protection BiologySammanfattning : The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. LÄS MER
