Table 5. Estimates from the home range model from the Sogn & Fjordane and Møre & Romsdal, with the best AIC fit predicting tick abundance within home ranges of resident animals, and winter and summer home range of migratory red deer.

Note that all variables are factors. Baselines are “summer” home range of migratory animals and year 2009 in Sogn & Fjordane and year 2011 in Møre & Romsdal. Individual ID of each red deer was fitted as a random term. HR = home range type. All ticks stages are pooled in these analyses.
