1. Modelling the effects of substituting pollinators in decline
Kandidat-uppsats, Lunds universitet/Matematik LTHSammanfattning : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. LÄS MER
2. The effects of a new gall midge in the Panamanian fig/fig wasp mutualism
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The mutualism between the fig tree and the fig wasp pollinator is an important keystone interaction for tropical forests. However, many antagonistic and parasitic species take advantage of the fig/fig wasp mutualism. One such parasite is the gall midge that develops inside fig syconia. LÄS MER
3. Urban Mutualism
Master-uppsats, KTH/ArkitekturSammanfattning : The city of Stockholm has set the goal to build 140 000 new residential units by 2030 to meet the demand of a growing urban population. Simultaneously we are seeing a decline in biodiversity in and surrounding the city. Some of the main factors are climate change, pollution, overexploitation and habitat destruction. LÄS MER
4. Cleaning interactions by bluestreak cleaner wrasse (Labroides dimidiatus) and moon wrasse (Thalassoma lunare) on pelagic thesher sharks (Alopias pelagicus)
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Cleaning symbioses are a well-studied mutualism among marine species. However, the interactions occurring between cleaner fish and sharks are lacking in research, which makes it a target for further investigation. LÄS MER
5. Preferences of the common garden ant (Lasius niger) in choice of aphid mutualist : Possibilities to increase biological control of the rosy apple aphid (Dysaphis plantaginea)
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : The aim of this study is to acquire knowledge about the preferences regarding aphids of the ant Lasius niger (common garden ant), commonly found attending aphids and protecting them agains their natural enemies in apple orchards around the world. By knowing this, it is hypothesized that another plant can be brought into an orchard carrying another aphid, more suitable as an ant-mutualist, to compete with the pest aphid present on site. LÄS MER
