Effects of Power Lines on Area Use and Behaviour of Semi-Domestic Reindeer in Enclosures

Table 4

Results from the best mixed logistic regression model of position (proportion of observations when an animal is in the lower half of the enclosure (zones 3 and 4)) of two trials with 12 domestic reindeer each. Animals of different degrees of tameness were tested separately. Intercept in all models is the estimate for zone 1 in a control enclosure. The model uses a logit-link.
