  1. Olfactory discrimination in South African fur seals (Arctocephalus pusillus) of aliphatic aldehydes, carboxylic acids and acetic esters Sandra Selin Final thesis. International Master Programme Applied Biology 2008Supervisor: Prof. Matthias Laska • Aims: • Determinethe olfactory discrimination ability of South African fur seals • Assess whether a correlation between discrimination ability and differences in carbon chain length exists • Conclusions: • South African fur seals have a well-developed discrimination ability for the odorant classes investigated • However, discrimination performance did not correlate with the frequency of occurrence of stimuli in their chemical environment • Results: • All seals successfully discriminated between 14 out of 15 stimulus pairs • No correlation between discrimination performance and differences in carbon chain length • None of the odorant classes was significantly better or poorer discriminated • Materials & Methods: • Odorants used differ in frequency of occurrence in the marine environment • Test method: Food-rewarded two-choice instrumental conditioning paradigm Circled in red: Two cases of failure to discriminate occurred, and both were within the same odorant pair.
