Fig. C1. Mean pack size tends to increase with total population density for the Northern Range wolf population (1996–2011, p = 0.04). The curve represents this relationship: pack size = 2.56density0.39. Pack size and density are related for some other wolf populations, for example, Upper Michigan [p < 0.01 (Roell et al. 2010)] and Isle Royale [p < 0.01, (Vucetich, unpublished data)]. In some cases, the influence of pack size on density also requires taking into account the number of packs in the population (e.g., Wisconsin [p = 0.06 for pack size and p < 10-7 for number of packs in the population, (Wydeven et al. 2009)]). In other cases, the relationship is Ç-shaped (i.e., Montana, [p < 0.01 (Hanauska-Brown et al. 2012)]).
