This study actually showed opposite results from another study and they mention that in their results:
Quote: Home ranges should be smaller if the pig’s living requirements are provided in a smaller area (Sanderson 1966), and when food was scarce during the winter, home range size increased (Kurz and
Marchinton 1972, Singer et al. 1981). Maillard and Fournier (1995) showed that with pig home ranges and movements increased with the onset of hunting pressure in the winter, then decreased when hunting pressure subsided. Our high pressure season (fall and winter) showed the opposite results.
Just more proof there are no absolutes.
