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

Figure 4

Observed positions and predicted use of lower half of the enclosure over time (hours after the start of the experiment) among treatment and control reindeer from two sources: domestic tame (Finnmark) and domestic wild (Vågå). A higher value illustrates more frequent use of the lower part of the enclosure. Lines represent the estimates from zone 1 (the model intercept). Dashed and solid lines represent treatment and control animals, respectively. The two lower lines represent domestic tame animals, while the two upper represent domestic wild. The distributions of observations of animals being located in the lower and upper part of the enclosure are shown as symbols at the top and at the bottom, respectively. Black and grey symbols represent domestic tame and domestic wild, respectively. Circles and squares represent control and treatment animals, respectively.
