1. 1. Training dogs to indicate synthetic pheromones from Plagionotus detritus, Coleoptera, Cerambycidae to detect living beetles

   Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

   Författare :Matilda Apelqvist; [2022]
   Nyckelord :Detection dog; indicate synthetic pheromone; coleoptera; conservation biology; endangered species;

   Sammanfattning : Using dogs to detect insects’ emitted volatiles is a non-invasive procedure, and a trained detection dog is potentially a fast and accurate method to search for saproxylic insects. The longhorn beetle Plagionotus detritus is categorized as Endangered in the Swedish Red List of Threatened Species. LÄS MER

3. 2. Meerkats (Suricata suricatta) are able to detect hidden food using olfactory cues

   Master-uppsats, Linköpings universitet/Biologi

   Författare :Ida Sörensen; [2018]
   Nyckelord :Buried food test; food odour; foraging; meerkat; olfaction; Suricata suricatta;

   Sammanfattning : Meerkats are known to strongly rely on chemical communication in social contexts. However, little is known about their use of the sense of smell in food detection and selection. LÄS MER

4. 3. Lipase activity in Swedish raw milk

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Julia Hartmann; [2018]
   Nyckelord :food technology; livsmedelsteknologi; raw milk; lipase activity; Technology and Engineering; Agriculture and Food Sciences;

   Sammanfattning : Bovine milk contains several enzymes which can affect the quality of milk. One of these enzymes are lipases which hydrolyse the triacylglycerides in milk. In this process off-flavours, odour and product defects are generated. LÄS MER

5. 4. Behavioural responses of mice to predator odour components

   Master-uppsats, Linköpings universitet/Biologi; Linköpings universitet/Tekniska fakulteten

   Författare :Thorbjörn Sievert; [2015]
   Nyckelord :predator; odour; olfaction; mouse; prey; neophobia; kairomone; avoidance; behaviour;

   Sammanfattning : Having means to detect and avoid potential predators is a necessity for prey species. Most mammalian prey species are able to detect odours emitted by predators and to adapt their behaviour accordingly. These odour cues are therefore considered to act as semiochemicals. Predator odours consist of several dozen different odourants. LÄS MER

7. 5. Behavioural responses in mice exposed to predator odour components

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska högskolan

   Författare :Desirée Sjöström; [2014]
   Nyckelord :Mice mus musculus ; Predator odourants; 2; 2-dimethylthietane; Methyl-2-phenylethyl sulfide; N-pentyl acetate; Behavioural response; neophobia; prey species;

   Sammanfattning : It is essential for prey species to be able to detect predators to avoid them. The sense of smell is used by a number of prey species for this purpose. The aim of the present study was to assess if one of the odourants that make up a predator odour is sufficient to induce a behavioural response in mice (Mus musculus). LÄS MER
