   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host-bacteria interaction; Helicobacter pylori; Neisseria gonorrhoeae; Lactobacillus; Epithelial cells; Macrophages; EGR1; Amphiregulin; SabA; molekylär biovetenskap; Molecular Bioscience;

   Abstract : Helicobacter pylori colonizes the human stomach, where it causes gastritis that may develop into peptic ulcer disease or cancer when left untreated. Neisseria gonorrhoeae colonizes the urogenital tract and causes the sexually transmitted disease gonorrhea. READ MORE

4. 12. Temperature and the synchrony of plant-insect interactions

   Author : Tenna Toftegaard; Johan Ehrlén; Karl Gotthard; Christer Wiklund; Annette Menzel; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brassicaceae; Anthocharis cardamines; climate change; development; oviposition; phenology; species interactions; herbivory; synchrony; timing; phenotypic plasticity; local adaptation; Plant Ecology; växtekologi;

   Abstract : Increasing temperatures resulting from climate change have within recent years been shown to advance phenological events in a large number of species worldwide. Species can differ in their response to increasing temperatures, and understanding the mechanisms that determine the response is therefore of great importance in order to understand and predict how a warming climate can influence both individual species, but also their interactions with each other and the environment.

5. 13. The effect of climate on oak-based species interactions : annual number of leaf flushes and insect voltinism

   Author : Álvaro Gaytán; Ayco J. M. Tack; Karl Gotthard; Kailen A. Mooney; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; food webs; latitude; leaf flush; plant-based species interactions; Quercus robur; voltinism; Ecology and Evolution; ekologi och evolution;

   Abstract : Plants interact with a large diversity of organisms, including insects and microorganisms. These species interactions are strongly influenced by climate, as illustrated by the advances in plant and insect phenology in response to increasing temperatures. READ MORE

6. 14. Trophic interactions and behaviour : Studies relevant to a Baltic Sea biomanipulation

   Author : Per B. Holliland; Sture Hansson; Elena Gorokhova; Peter Tiselius; Stockholms universitet; []

   Abstract : The main theme of this thesis is the interactions of animals with the environment and each other. The thesis was written within the framework of a biomanipulation project “Pikeperch in Himmerfjärden”. READ MORE

7. 15. The birds in the Iliad. Identities, interactions and functions

   Author : Karin Johansson; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; ancient ornithology; birds; bird symbolism; divination; double motivation; divine intervention; Homer s Iliad; identity; messenger; metaphorical utterances; oral tradition; parallelism; semiotics; species interactions; transformation; transmitter; Trojan war;

   Abstract : As the topic of this study embraces and entwines what is routinely divided into two separate categories, “nature” and “culture”, the birds in the Iliad challenge modern scientific division and in some ways, our thinking. They are simultaneously birds, signs and symbols. READ MORE
