Investigating dog behaviour
During my PhD at Lund University (2004-2008), I investigated the colour vision in the trichromatic nocturnal helmet gecko and the dichromatic horse. Now I am, besides teaching in Ethology (part 1-2), The behavioural biology of dogs (part 1-3) and The senses and behaviour of the horse, working in Per Jensen's research group at LiU, investigating dog behaviour and recently also their visual abilities.
During my time in the dog research group I have designed a problem solving task which is now frequently used in our different dog projects. The problem solving test has revealed interesting behavioural results within a large population of beagles (Persson et al. 2015) which now enable us to further investigate interesting candidate genes influencing the contact seeking behaviour of dogs. I have also developed and validated a fast, but standardised method to characterise behavioural variation in pet dogs in a social settings e.g. during training classes (Roth & Jensen 2015). A method that includes both human and dog interactions without any sudden or fearful test batteries.
Lastly, we have also started a project on measuring long-term cortisol levels (stress hormone) incorporated in dog hair. Our first paper on this is now published and reveals how hair cortisol varies with sason and lifestyle (Roth et al. 2016) but also that positive human interactions are associated with low cortisol levels.
