1. Födovalspreferenser hos en arktisk specialist : vad föredrar Gynaephora groenlandica (Lepidoptera:Erebidae) att äta på Wrangelön?
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : The Arctic tundra has many unexplored areas. Due to the harsh climate and the difficult accessibility, there is a lack of knowledge about the different species that live under these circumstances. Herbivores in this environment have a large effect on the plant community, one of these is the moth butterfly larva Gynaephora groenlandica. LÄS MER
2. Effect of Touch on Cotton and Maize : influence on plant morphology and feeding preference in Spodoptera littoralis
Kandidat-uppsats, SLU/Dept. of Plant Protection BiologySammanfattning : Plants are constantly exposed to touch and mechanical stimuli in natural environments, from rain, wind, animals and plant neighbours. However, current knowledge and understanding of how touch physiologically affects plants are limited. LÄS MER
3. Interactions between plant pathogens and their implications for crop protection
Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : One plant may often be infected by more than one pathogen species. It is assumed that species which exploit the same resource have the potential to affect each other. Plant diseases where more than one pathogen is involved in the development of infection are usually termed as ¨disease complex¨. LÄS MER
4. Reindeer induced changes in vegetation composition and plant traits on a tundra-forest border
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. LÄS MER
5. Induction of plant defence and secretion of volatile compounds by Colletotrichum acutatum in leaf infection assay of woodland strawberry
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Consumers demand healthy food with less residues of pesticides, in addition to the global awareness of the negative impact such chemicals have caused to the environment during the last decades. Farmers and other agricultural participants are far away from completely end up the usage of pesticides but currently used practice could stepwise be improved in pest management. LÄS MER
