1. 16. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences

   Författare :Cecilia Mille-Lindblom; Lars Tranvik; Helmut Fischer; Eric Chauvet; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; fungi; decomposition; antagonism; extracellular enzymes; competition; macrophytes; dissolved organic carbon DOC ; ergosterol; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. LÄS MER

3. 17. Ecology of nematophagous fungi in agricultural soils

   Författare :Lotta Persmark; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic farming; Fungistasis; Competition; Bacteria; Conidial traps; Rhizosphere; Seasonal variation; Distribution; Endoparasitic; Nematode; Nematode-trapping; Ecology; Ekologi;

   Sammanfattning : Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. LÄS MER

4. 18. Modelling European Combined Transport as an Industrial System

   Författare :Johan Woxenius; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the systems approach; actors; the network approach; industry structure; competition; combined transport; resources; ownership relations; activities; intermodal;

   Sammanfattning : The purpose of this thesis is twofold: developing a method for analysis of the European combined transport industry as well as utilising the developed method to describe and analyse the industry. The second part of the purpose could also be stated as verifying the method, but the description and analysis is carried out somewhat more carefully than just for the purpose of verifying the method.

5. 19. Self-Image and Economic Behavior

   Författare :Margaret Samahita; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; self-image; social image; signaling; Pay-What-You-Want; competition; co-operation; communication; selfie;

   Sammanfattning : This thesis consists of four papers studying image concerns in three unique settings. The first paper develops a model incorporating self-image into the buyer's utility in a ''Pay-What-You-Want'' (PWYW) pricing scheme. LÄS MER

7. 20. Resources, the environment, and sex : Examining variation in sexually selected traits in a livebearing fish

   Författare :Erika Fernlund Isaksson; John Fitzpatrick; Gil G. Rosenthal; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mate choice; sexual selection; competition; resource restriction; condition dependence; etologi; Ethology;

   Sammanfattning : Striking variation is observed in sexually selected traits. These traits influence the outcome of competition and choice before and after mating. Before mating, animals compete for the access to mating partners and choose who to mate with between several potential mates. LÄS MER
