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

Figure 3

Observed activities and predicted proportions of restless behaviour over time (hours after the start of the experiment) among treatment and control reindeer from two source populations: domestic tame (Finnmark) and domestic wild (Vågå). Lines represent the estimates from zone 1 (the model intercept). Dashed and solid lines represent treatment animals and control animals, respectively. The two lower lines represent domestic tame animals, while the two upper represent domestic wild. The distributions of observations of restless and nonrestless behaviour 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.
