From: Seasonal variation in space use and territoriality in a large mammal (Sus scrofa)
Predicted relationships evaluating territoriality among animals based on spatial overlap in home ranges (HR) and core areas (CA). Interactions can occur between two individual’s home ranges (HR–HR), between one individual’s home range and another individual’s core area (HR–CA), or between two individual’s core areas (CA–CA). If animals are not territorial, spatial overlap is expected to be the same across HR–HR, HR–CA, and CA–CA comparisons (solid line). If animals are territorial, it is expected that spatial overlap will decrease between HR–HR and HR–CA comparisons [dashed line; consistent with Burt (1943) and Schoener (1968)] or among HR–HR, HR–CA, and CA–CA comparisons [dotted line; consistent with Gabor et al. (1999), Darden and Dabelsteen (200), and Pierro et al. (2008)].
