Welcome to the webpage for my master's thesis!

Animals can suffer from impaired anti-predator responses when held in captivity without predation pressure for numbers of generations. One possible way of preventing loss of these possibly vital behaviors is to use predator models as environmental enrichments in captive environments.

At Parken Zoo in Eskilstuna, two different endangered species of tamarins are held. The purpose with this study was to evaluate the effectiveness of using two different predator models in inducing anti-predator behaviors in these tamarin groups. By using predator models in the zoo, perhaps the future generations of these tamarins could get better prepared for a life in the wild when they are to be reintroduced.
