4. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

5. Påverkas anknytningsbeteende hos hund av ägarens personlighet och/eller vuxna anknytningsstil?
University essay from SLU/Dept. of Clinical SciencesAbstract : Hunden kan skapa ett band med sin djurägare som är lika unikt som viktigt. Genom evolutionära anpassningar och selektiv avel och har flera förändringar skett som förändrat hundens morfologi, anknytningssystem och belöningssystem. Ett resultat av detta är bland annat hundens förmåga att forma anknytningsband till sin djurägare. READ MORE
