1. 1. The behavioural response of mice to predator odours

   Kandidat-uppsats, Biologi; Tekniska högskolan

   Författare :Torbjörn Blixt; [2012]
   Nyckelord :Predator odour; prey speceis; neophobia; habituation;

   Sammanfattning : The ability to detect and react to a predator odour is crucial for prey species. In the present study 10 mice (Mus musculus) were used to test the behavioural response of mice towards two predator odours (3-methyl-1-butanethiol and 3-mercapto-3-methyl-butan-1-ol) and one fruity odour (n-pentyl acetate).

3. 2. Magnetic grain-size analyses of Holocene sediments in the North Atlantic and Norwegian Sea : palaeoceanographic applications

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Nyckelord :magnetic grain-size; magnetic hysteresis loops; Reykjanes Ridge; Vøring plateau; North Atlantic; Norwegian Sea; deep ocean currents; Holocene; magnetisk kornstorlek; magnetiska hysteresis-lopar; Reykjanesryggen; Vøringplatån; Nordatlanten; Norska havet; djuphavsströmmar; Holocen; Earth and Environmental Sciences;

   Sammanfattning : High-resolution magnetic hysteresis measurements were carried out on three sediment cores, one from the North Atlantic and two from the Norwegian Sea. These measurements can be used to reconstruct changes in magnetic grain-size. Physical grain-size has been interpreted as a proxy for bottom current intensity (McCave et al. LÄS MER
