1. 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
2. Effect of Aggregatibacter actinomycetemcomitans Leukotoxin on ATP Release through Pannexin Channels in Human Monocytes
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologiSammanfattning : Aggregatibacter actinomycetemcomitans is strongly associated with aggressive periodontitis and one of several virulence factors is a leukotoxin (LtxA). The toxin has a consequential impact on human leukocytes which leads to an interference with the host ́s defences due to a chain reaction involving activation and release of a pro-inflammatory cytokine; interleukin-1β (IL-1β).

3. Predator-induced morphological defences in a freshwater snail
Master-uppsats, Institutionen för ekologi, miljö och geovetenskapSammanfattning : The ability of a certain genotype to express different phenotypes depending on variations in the environment is called phenotypic plasticity. Predator induced defences are among the most studied and wide spread examples of phenotypic plasticity. LÄS MER
4. Differences in exocuticle thickness in Leucorrhinia dubia (Odonata) larvae from habitats with and without fish
Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)Sammanfattning : Many prey species are able to develop different morphological structures as defence against for example predators. Some of these structures are induced only by individuals exposed to a predator. This phenomenon is called phenotypic plasticity. LÄS MER
